At some point, most homeowners face the decision to repair or replace their air conditioning system. A repair is often more cost-effective up-front. However, AC replacement can have many benefits. Your air conditioning contractor can help you decide and weigh the benefits of each option. We’ll look at a few perks of replacing your AC unit and when a repair is the best choice for now.

Reasons You Should Consider AC Replacement

There are many benefits to replacing your air conditioner. While you may have become attached to your AC over the past few years, a replacement may be the right decision. These are some reasons to go this route:

• Repair Costs Are Adding Up: Even if your AC needs a minor repair, it can cost hundreds of dollars. You may pay thousands of dollars for a major repair. But even if you’re not facing repair bills that high, consider how frequently your AC requires service. To determine if a repair is worth it, multiply the estimated repair cost by the unit’s age; if it exceeds the cost of a new model, go with AC replacement. Or, if a repair costs over 50% of installation, replace the system.
• Your AC Is Aging: Most home ACs last 10 to 15 years, but depending on the system, they can last longer. However, a unit older than 10 years that requires extensive repairs should usually be replaced. Older air conditioners are less efficient to begin with, and they’re more likely to break down and require additional repairs. You’re just wasting money by fixing a 20-year-old air conditioner time and again.
• Energy Efficiency Is Decreasing: An AC works less efficiently as it ages. Also, older models weren’t designed to be as energy-efficient as modern ones. Higher energy bills are one disadvantage of keeping your aging AC going. You may also be dealing with temperature control issues. A new air conditioner provides more consistent temperatures while saving on energy each month.
• Indoor Air Quality Is On the Decline: A malfunctioning air conditioner is less effective at maintaining good indoor air quality. Excessive dust, particulates, and other pollutants can lead to respiratory and other health issues. Replacing an old AC is one of the best ways to improve indoor air quality. Newer units have more effective filters and are designed to newer standards that require homes to have cleaner air.
• Old ACs Can Be Hazardous: An aging air conditioner can be a safety risk. Worn components and faulty wiring can increase the risk of a fire. Some systems still use R-22 Freon, which depletes the ozone layer and is an environmental hazard. If your AC has a coolant leak, it’s an immediate risk to your health and safety, as refrigerant is toxic.

Can I Get By with an AC Repair?

You may not yet need AC replacement if there are issues such as:

• Warm air blowing due to a faulty or incorrectly set thermostat, dirty filter, or restricted airflow caused by clogged ducts.
• A refrigerant leak if a line can be sealed and your AC system uses the latest acceptable refrigerant.
• The air conditioner runs constantly due to a clogged filter, dirty coil, low refrigerant, or a malfunctioning thermostat.
• Loud, unusual noises are caused by a loose, dirty, or damaged part; in this case, the affected part can be cleaned or replaced.
• Restricted airflow from vents, which can be resolved by cleaning or sealing air ducts or fixing the motor or blower.

How Do I Decide on AC Repair or AC Replacement?

To make a decision, you need to determine the cause of the issue. Many AC issues, even if the system is older, are caused by simple problems. The more complex the issue or the more components it involves, the more likely your HVAC contractor will recommend AC replacement. Therefore, a technician must evaluate the extent of the damage. A repair makes sense if it entails replacing a small, inexpensive part; if the system is over 15 years old and requires a large, costly part, it should be replaced.

Air conditioner maintenance can help keep your home cool, improve energy efficiency, and avoid major repairs. Several different tasks, whether DIY or completed by a reputable air conditioning company, help your AC run more smoothly. That’s why we recommend scheduling AC maintenance at least once a year. If you want your air conditioning system to be reliable and last longer, don’t forget these tasks:

1. Check the Filter and Replace It As Necessary

Ensuring the air filter is clean is one of the most important AC maintenance tasks. Checking and cleaning/changing the filter is a simple DIY task and takes little time out of your schedule. If a filter gets blocked, reduced airflow will cause the unit to work harder and become less efficient. In a ducted system, it can also cause indoor air quality issues.

Disposable filters need to be replaced. Other filters can be removed, cleaned with running water, dried, and reinstalled. To access the filter, turn off the HVAC system and open the service panel. Most filters slide out easily, so cleaning or replacing one is a basic task.

2. Keep the Indoor Unit Clean

The indoor evaporator unit tends to get dirty over time. Layers of dirt, dust, and grime can build up on the coil and blower, reducing performance and leading to a musty or moldy smell. 

To clean the indoor unit, wipe it down with a clean cloth or feather duster. You can also spray the cloth first with a cleaning or antibacterial solution and wipe down the casing. If possible, clean the evaporator coil too. For a more thorough chemical cleaning of components inside the system, hire a qualified HVAC technician.

3. Compare the Thermostat Settings with the Indoor Temperature

One way to know your AC is working properly is to verify the thermostat setting and air temperature match. The thermostat should automatically turn the system on and off to maintain the set temperature. It should also show the air temperature, but you can also use a separate thermometer to verify the reading. If the numbers differ, check if the thermostat is properly set, if the AC needs a new filter, or if there’s an issue with the drain or evaporator coil.

4. Inspect the Condensate Drain and Clear Any Blockages

Your air conditioner collects condensation that forms during the cooling cycle. A built-in tray/pan and drain allow this moisture to be collected and directed outdoors. However, a blockage of grime, mold, algae, or pieces of insulation can cause water to back up and overflow, leading to possible odors and water damage. The drain can be cleared out using a vacuum cleaner at the end of the condensate pipe; depending on the severity of the issue, you may want to call an AC maintenance professional for this.

5. Clean the Condenser Unit and Surrounding Area

Since the outdoor unit is exposed to the elements, dirt, leaves, twigs, and other debris can collect on, in, or around it. Remove these and any items or objects nearby. Leave at least two feet of clearance on each side to avoid airflow and heat transfer issues. These simple DIY tasks can protect the condenser unit:

• Remove any nearby storage boxes, bins, or home/garden equipment.
• Wipe the casing with a damp cloth to remove dirt, dust, or plant matter.
• Clean fine debris with a vacuum cleaner and brush attachment.
• Use a garden hose to gently spray the fins clean.
• Carefully straighten any bent fins with a fin straightening tool.

6. Make Sure Your AC System Is Properly Insulated

The insulation surrounding the copper piping, which looks like a black or white foam rubber material, helps maintain thermal efficiency. This is important as the refrigerant flowing through the lines enables your HVAC system to cool your home. Don’t try to replace damaged insulation yourself. If you find material that’s broken, crumbling, or missing and exposed sections of pipe, call a licensed contractor.

7. Schedule a Duct Cleaning Every Few Years

Unlike routine AC maintenance, duct cleanings aren’t recommended often, but can help extend the life of your air conditioner. A buildup of dust and debris can restrict airflow, straining the system and causing damage or a breakdown. It can also lead to poor indoor air quality. Aside from wiping down or removing and washing grilles and cleaning accessible vent spaces, you should hire a professional with the tools and expertise to properly clean ductwork.

8. Schedule Annual Maintenance

Making that phone call or online request every year is an important AC maintenance task. A professional will visit your home to inspect your air conditioner and perform tasks such as:

• Thoroughly clean AC components
• Lubricate the system’s moving parts
• Inspect and tighten electrical connections
• Test all electrical components
• Perform a complete AC tune-up
• Replace the air filter
• Check refrigerant levels
• Check the thermostat
• Inspect the blower motor
• Look for and seal duct leaks
• Inspect the coils for frost or damage
• Clear the condensate drain line

Air conditioning repairs in Northern California can be expensive, but you can avoid a costly AC repair by being proactive with at-home and professional maintenance. Like any machine, an air conditioner has parts that wear out. However, equipment malfunctions and breakdowns are not inevitable. You can avoid calling for AC repair near you, and potentially save hundreds or even thousands of dollars (leaving more money in your budget), by following these tips:

• Don’t Forget Routine Maintenance
• Change the Air Filter as Recommended
• Avoid Overusing Your Air Conditioner
• Clean Around the Outdoor Unit
• Look For Dirt Inside the Unit
• Check the Thermostat Regularly
• Keep the Vents Open
• Inspect the Condensate Drain for Blockages

1. Don’t Forget Routine Maintenance

Your air conditioner should be tuned up at least once a year. Annual maintenance is the most effective way to avoid costly AC repairs. The system should be inspected, cleaned, and, if necessary, repaired before the cooling season starts. During maintenance, a technician should:

• Clean the evaporator and condenser coils
• Check refrigerant levels
• Lubricate moving parts
• Tighten electrical connections
• Address any electrical issues
• Look for and seal any duct leaks
• Check the thermostat and system controls
• Clear the condensate drain (if necessary)

2. Change the Air Filter as Recommended

A dirty or clogged air filter can reduce or block airflow. The air conditioner’s manufacturer will recommend the best interval for changing the filter. In general, an AC filter should be changed every one to three months, depending on the system and your home’s indoor air quality. Neglecting to replace the filter can reduce cooling performance, force the system to work harder, and lead to higher energy bills. Low airflow can also cause strain that damages the unit, requiring costly repairs.

3. Avoid Overusing Your Air Conditioner

The more you use your AC, the more wear and tear it will experience. Using an air conditioner less may not seem like an option during a hot summer. However, raising the thermostat by a few degrees not only saves energy but can also reduce the unit's demand. 

How can you do this without sacrificing comfort? Running a ceiling fan can make the temperature feel 3℉ or 4℉ cooler, offsetting a slight increase in the thermostat setting. Also, turn the AC off when you go to work, leave for a vacation, or are otherwise away from home.

4. Clean Around the Outdoor Unit

Debris can restrict airflow and potentially contaminate the system, especially if it builds up around the outdoor unit. Regularly check for leaves, branches, grass, dirt, and other items around the condenser unit. Also, trim foliage back. There should be at least two feet of clearance on all sides.

When cleaning the unit, make sure it is shaded. Direct sunlight can strain the system and overheat the compressor. Additionally, make sure there’s a barrier that prevents small animals from getting into the unit.

5. Look For Dirt Inside the Unit

Your AC’s coils and fins are prone to getting dirty. If they become coated, this can interfere with heat transfer and may also damage the coils, especially if they freeze. Combined with restricted airflow, dirt can cause the system to work harder and less efficiently. The unit can even overheat and break down. 

If you have some experience, you can turn off the system, open the unit, and vacuum out excess dirt. The coils and fins can be cleaned with a soft brush. But this may require removing the fan and other components. Call a professional if you notice the unit is dirty and you haven’t cleaned it before.

6. Check the Thermostat Regularly

The thermostat is a small part of your HVAC system but can malfunction and cause numerous issues. A faulty thermostat can cause your AC to run constantly or short cycle. Avoiding these issues can prevent wear and tear that can damage your air conditioner. 

Look for changes in accuracy to determine if your thermostat needs to be checked by a professional. This can indicate an issue with placement or a low battery. A wiring problem can also affect how the thermostat works and trigger an electric shock or a fire.

7. Keep the Vents Open

Don’t close vents in unused rooms. People often do this thinking they can save energy. However, closed vents can disrupt airflow and create pressure variances that can damage your AC system. Also, make a visual note of where the vents are and avoid blocking them with storage units, furniture, or drapes.

8. Inspect the Condensate Drain for Blockages

The condensate drain is another important part of your AC system. An air conditioner collects moisture from the air, which is removed via the condensate drain. If this drain gets clogged, mold and algae can grow inside it. Water damage can occur if the drain overflows. Since unclogging the line can be a tricky process, it’s best to hire a professional for AC repair.

A ductless mini-split AC is a reliable, efficient solution whether you’re building a new home or retrofitting an older one. It is becoming a popular air conditioning option for homeowners. Consisting of an outdoor unit and one or more indoor units, a mini-split is a flexible solution with many advantages, from personalized comfort to improved efficiency. 

Is it nearing the time for air conditioning installation or replacement in your home? Here are some pros and cons of ductless mini-split ACs to help you decide.

Pros of Ductless Mini-Split ACs

The many benefits of installing one of these systems include:

• Simpler Installation: A ductless mini-split AC system consists of an outdoor unit, indoor air handlers, and a conduit between them. Eliminating ductwork simplifies installation. No significant home modifications are needed, except for drilling a small hole in an exterior wall for the conduit, which contains the refrigerant, drainage, and electrical lines.
• Flexible Placement: Indoor units can be placed wherever you need cooling. They are typically installed high up on a wall, while ceiling cassettes and other space-saving options are available. Compact designs can blend in with your interior decor. No matter where you choose to install a mini-split unit, complex demolitions or renovations are avoided while floor space is preserved.
• Zoned Temperature Control: A central HVAC system conditions all the air in your home at once. However, a ductless mini-split AC provides zone-based temperature control. Each indoor unit can be operated independently, meaning the temperature can be set per each occupant’s preferences or a building’s layout and usage. You can also keep bedrooms cooler than the living room. Units in unoccupied spaces can be turned off to save energy.
• Increased Energy Efficiency: There’s less energy consumption for a few reasons. Mini-split ACs eliminate energy loss from ductwork, avoid cooling areas that don’t need it, and use inverters that adjust compressor speed to match specific temperature needs. Some mini-split systems also double as heat pumps, which provide heating and cooling. With a ductless system, any level of efficiency equals reduced operating costs.
• Improved Indoor Air Quality: Not only do these systems avoid the buildup of dust and particulates common in ductwork, but they also have higher-quality, multi-stage filtration systems that effectively remove dust, mold, and bacteria. This is ideal for occupants with allergies or respiratory issues. Ductless mini-split ACs are effective at controlling humidity as well; by removing excess moisture, they can help prevent mold, eliminate stuffiness, and promote an overall healthier living space.
• Quieter Performance: Other HVAC systems tend to produce more noise. However, these systems are quieter. They can operate as low as 19 decibels, or the sound level of a whisper. You don’t have to be distracted by the humming, whirring, or banging sounds that are common with ducted systems. The air handlers can also be placed farther away from the outdoor unit so the compressor’s noise and vibration won’t distract you.

Cons of Ductless Mini-Split ACs

Despite their many benefits, there can be downsides, including:

• Higher Installation Costs: The initial cost is often higher than installing a central AC (however, it’s often offset by energy savings throughout the system’s life). Purchasing multiple indoor units can add to the expense. Furthermore, the system’s power requirements may justify electrical modifications and upgrades, while electrical connections require a qualified professional. And, depending on the system’s configuration, you may need to purchase a condensate pump.
• Indoor Units Can Have Aesthetic Impacts: You may need to move interior decor to make room for indoor air handlers. Some people are distracted by their placement throughout their homes. Outdoor units can be bulky and obtrusive, which can be addressed with proper placement or the use of covers or panels. Your HVAC installer can provide equipment and design options that reduce the visual clutter and maximize both functionality and aesthetics.
• Limited Capacity for Large Spaces: Compared to other air conditioners, the units are designed to cool smaller areas. Therefore, you may experience uneven cooling or a limited airflow range in a large room. Ductless mini-splits come in different sizes. Consult with your HVAC professional to determine the best system for your home.
• Reduced Performance During Extreme Temperatures: These systems work best in moderate climates. However, in extremely hot conditions, a ductless AC’s cooling performance may be limited. Extreme cold can also cause issues; you may need a supplemental heating system if your mini-split doesn’t have a sufficient heat source.
• Maintenance Requirements: A mini-split is efficient and versatile, but requires regular maintenance. The air filters must be changed or replaced regularly (for every air handler installed), and you should check for visible issues with equipment every three to four months. The outdoor unit must be kept unobstructed to maintain proper airflow. A technician must check refrigerant levels and ensure there are no electrical hazards. These tasks reduce the risk of breakdowns and can increase system longevity.
• Possible Noise Concerns: The noise level of a ductless mini-split depends on the equipment model and placement. This is especially true if the outdoor unit is close to a bedroom. Some municipalities have stricter noise regulations. A professional can help address these concerns by selecting options with low-decibel ratings and cleaning the fan and motor often.

To benefit from AC replacement, you must find the right AC unit for your home. It’s important to consult with an air conditioning service contractor. Whether your existing system is reaching the end of its life or is outdated, you have an opportunity to find a more energy-efficient system. However, ignoring important details or making a mistake can have costly consequences.

Finding the right AC unit requires knowing the size of the model you need. We’ll look at numerous factors related to air conditioner sizing and other variables to discuss with your HVAC contractor. 

Square Footage

Square footage isn’t the only size variable to consider when selecting an AC unit. Nonetheless, the square footage of individual rooms and your entire home is usually the first place to start. The larger your home, the more cooling capacity you need. Miscalculating capacity can mean getting too much or too little cool air and spending more on energy.

Ceiling Height

Ceiling heights aren’t included in square footage, but if your home has higher ceiling heights than average, it will require more power to be properly cooled. Ceiling height also influences air circulation. You’ll need a higher-capacity unit to counteract the accumulation of rising warmer air. Irregular airflow patterns caused by sloped or vaulted ceilings must also be considered. 

Number of Windows

It may seem less obvious, but windows have a big impact on an AC unit’s efficiency. If you have a lot of south- and west-facing windows, more sunlight causes higher heat gain, requiring a stronger AC. Other window-related AC sizing factors include:

• Number of Windows: More windows mean more opportunities for heat gain and air leakage.
• Age of Windows: Older windows tend to let more air seep in and are less insulated.
• Window Coverings: Blinds, curtains, and other coverings help windows be more efficient by blocking out sunlight.

Insulation

Insulation in walls, ceilings, and attics can affect AC efficiency. Each insulating material has an R-value; the higher the number, the greater a material’s thermal resistance (ability to prevent heat transfer). Replacing old materials or filling in poorly insulated gaps or spots with high R-value insulation can reduce energy consumption.

Climate

The climate conditions in your area determine how much cooling you need. A smaller air conditioner won’t perform well in soaring summer temperatures, and if your region sees cooler summers, a larger system may not be cost-effective. Nonetheless, you must consider the temperature range throughout the year, along with typical humidity levels.

About Calculating Cooling Capacity

The capacity of an air conditioner is measured in British Thermal Units (BTUs). The larger your home, the more BTUs you’ll need, but the requirements vary. For example, a well-insulated, shaded room generally needs 25 to 30 BTUs per square foot, but rooms with average insulation and moderate sun exposure may need 30 to 35 BTUs per square foot. However, a brightly lit room with poor insulation can require 35 to 40 BTUs per square foot.

Therefore, capacity requirements can vary significantly. Other factors that influence BTU requirements include the number of occupants, lighting fixtures, and the presence of heat-generating appliances. For a novice, working all these variables in a calculation can be overwhelming.

An HVAC professional has an easier way to perform a load calculation and find the right AC for your home. They may use formulas to input specific numbers. Or, they can use load calculation software tools that further streamline the process. This means load calculations can take less time, but this doesn’t minimize their importance at all.

About Efficiency Ratings

Every air conditioning unit has an efficiency rating on its label. You can use this to compare units and predict how a system will operate under standard conditions. Energy efficiency ratings include:

• Seasonal Energy Efficiency Ratio (SEER): This is an air conditioner’s cooling efficiency throughout a typical cooling season. Higher SEER ACs cost more upfront but consume less electricity and can save money over time.
• Energy Efficiency Ratio (EER): By measuring a unit’s cooling capacity under standard conditions, its EER can estimate how it will perform during peak demand and predict how it will operate during extreme temperatures.

Finding the Right Type of AC Unit

Sizing, efficiency, and other factors are heavily considered. It’s also important to consider the best type of unit. If you have a small home or a smaller room to cool, a window unit is an option. Central air conditioning systems are often used to cool entire homes; they use ducts to distribute air throughout the space. 

However, a split unit is better suited for cooling a smaller space or individual room. More advanced solutions include heat pumps (provide both heating and cooling) that are even more efficient. Another option is a mini-split; it allows you to zone your home for different levels of heating or cooling in different locations.

Additional Considerations

An AC unit must fit in the available space. If you have a small home, you may have fewer options. Also, consider the HVAC equipment you have. Does it match the AC unit you want to install? Will the new AC and your ductwork be compatible? If your ducts aren’t the appropriate length and diameter, issues with air velocity and pressure drop can affect performance and efficiency. To avoid persistent issues, you may want to consider replacing your entire HVAC system.

Faulty AC coils can cause serious problems, so schedule AC repair as soon as you notice something is wrong. Evaporator and condenser coils transport refrigerant so an HVAC system can collect and dissipate heat. It won’t do so effectively if the coils are damaged. Fortunately, the effects are noticeable, so you should know when to call a local AC contractor.

How Do AC Coils Work?

The evaporator and condenser coils are connected by coolant lines, which bring refrigerant to and from the condenser. A fan in the condenser unit dissipates heat from the refrigerant in the lines. The compressor then pumps the coolant back to the evaporator, where coils absorb heat and a blower pushes cool air into ducts. The coolant returns to the condenser to dissipate heat once again.

Signs You Have Faulty AC Coils

The most common effects of faulty AC coils in your home include:

• Refrigerant Leak: A leak can occur if an object falls against the coils. The coils can also become corroded due to exposure to acidic compounds in the air. If you see a refrigerant leak, call for help right away. It can do major damage to your AC and is a toxic chemical; exposure can lead to skin and respiratory problems.
• Environmental Damage: Coolant can harm the environment if it leaks from a damaged AC coil. It can contribute to atmospheric warming and ozone layer depletion (especially older R-22 Freon). A hissing sound from the coils means refrigerant gas is escaping.
• Reduced Cooling Efficiency: Refrigerant enables your AC system to generate cool air. A lack of cooling is one of the leading signs of faulty AC coils. Damaged coils cannot absorb heat effectively, so the system may not cool your home, or the cooling it provides will be inconsistent. Some rooms can be much cooler than others instead of the normal uniform distribution of air.
• A Noisy AC: Most air conditioners operate nearly silently. You should be used to the sound of the fan and airflow. If the evaporator coil is broken, you may hear a hissing or banging noise. These sounds mean refrigerant is leaking or loose or misaligned components are hitting other parts of your AC system. Ignoring any unusual noises can lead to even more significant damage.
• Frozen Coils: Ice can form on coils due to a refrigerant leak. Low refrigerant levels reduce the amount of heat transported through the lines, cooling them enough to cause condensation to freeze (poor airflow can also do so). The ice further contributes to the problem because it insulates the refrigerant, inhibiting heat transfer. Therefore, the air in your house is not cooled.
• Higher Energy Bills: Worn or damaged coils force your air conditioner to work harder to maintain a cool temperature. The extra work increases energy consumption. As a result, your monthly energy bills may increase suddenly or gradually without a clear reason. And, if your AC system works harder for a long period, major components can wear out, requiring costly repairs.
• The AC Short Cycles: The air conditioner may cycle on and off frequently if the evaporator coils can’t absorb enough heat. Short cycling wastes energy and can strain the system. The extra wear and tear can lead to expensive repairs or premature system failure. Call an AC contractor near you if the unit starts to run in shorter cycles.

How Do I Protect My AC Coils?

Check the AC coils often to reduce the risk of damage. Dust, hair, grime, and dirt can build up on them over time. The longer you wait, the harder the buildup is to remove. Use an AC coil cleaner or hose off outdoor coils to prevent damage, or call a contractor for help. If the coils freeze, have them check for a leak or airflow issue and, if necessary, correct it.

What’s the Safest Coil Cleaner to Use?

Use an AC coil cleaner that’s labeled for use with your type of system. The user manual or your AC installer may recommend certain products. You can also use a mix of water and mild dish detergent, and even add a little distilled white vinegar, for effective cleaning.

Should a Faulty AC Coil Be Repaired or Replaced?

Coils may be sealed or repaired if the damage is limited to a small area. However, a leak is often caused by eroded metal and corrosion. If part of the coil is corroded, other areas are likely affected. An HVAC contractor will generally recommend replacing it, which can be less expensive than a repair and recharge.
