Short cycling, which is when your HVAC system turns on and off too frequently, is a common problem. It can be harmful to your heating and cooling system and signal a variety of issues. Some of these can require air conditioning repair, so you don’t want to ignore a unit that has short cycles.
At Trio Heating & Air, our licensed technicians can quickly diagnose the underlying issue and provide any repair necessary. We recommend scheduling service before the damage adds up and leads to more costly repairs. But let’s explain the issue further to help you understand its scope and causes.
An HVAC system runs for a time, then turns off before turning on again if your thermostat is in “Auto” mode. One on/off period is called a “cycle”. It should last from 20 to 30 minutes, so your heating or cooling unit cycles two to three times per hour.
The system should turn off when the set temperature is reached. While actual cycle times can vary depending on your system and home, problems can occur if your HVAC unit runs too briefly. If it does, this is called short cycling. It can cause the system to use more power, increase your utility bill, and limit cooling or heating performance.
Short cycling occurs most often with single-stage systems. They only turn on and off, so an AC runs at full blast every time it’s too warm. Two-stage systems have more flexibility to adjust to conditions, while variable-speed ACs and furnaces run at incremental power levels, eliminating the need for cycling. They can stay on all the time but use less energy.
When an HVAC unit short cycles, it turns on and off again repeatedly in quick intervals. The compressor continuously starts up and shuts down. This not only wastes energy but also overworks the system. Parts of the compressor can wear out quickly. Or, the compressor can overheat and burn out, leading to one of the most costly AC repairs.
The constant starting and stopping can also accelerate wear on other components. This means you may eventually deal with more frequent repairs. Addressing the issue can avoid needing another repair shortly after your HVAC unit is fixed.
One or more issues can cause your cooling and heating system to short cycle. Therefore, short cycling can signal that there are multiple issues with your HVAC system. Here are some reasons the unit won’t stay on long enough.
You’ll save time and money by planning for installation with a Manual J load calculation. It helps your local HVAC contractor properly size your new system. Short cycling and other issues can be avoided.
If you notice your cooling or heating system turning on and off every five to ten minutes, it is short cycling. It isn’t always an obvious issue, especially if your HVAC system is relatively quiet or its familiar sound blends in with background noises. Subtle signs include a slight decrease in cooling or heating performance. Increased humidity, which can make your home quite uncomfortable, is another sign your AC isn’t running long enough.
Short cycling can be bad for your HVAC system. However, it can be prevented and there are solutions to address it, including the following:
If your HVAC system is short cycling, our licensed technicians can determine why and perform the appropriate adjustments or repairs. We not only ensure your satisfaction but also the optimal performance and efficiency of your AC or furnace. The goal is to find the best solution for your home.

You can avoid or delay thermostat repair with proper maintenance. A well-maintained thermostat generally lasts about 10 years. Although one of the least expensive HVAC components to replace, it’s crucial for reaching and sustaining optimal temperatures in your home.
A thermostat is wired directly to your heating and cooling system. It allows for the temperature to be adjusted and the system to be turned on and off manually or automatically. Therefore, thermostat maintenance should be part of your routine. These are some tips to keep it in top shape:
A low battery reduces the amount of power available to your thermostat. This can make it inaccurate and less able to manage your comfort. To avoid these issues, replace the thermostat batteries every six months or as the manufacturer recommends. Even if your thermostat is hardwired, it may have backup batteries. Change these to prevent disruptions in heating and cooling due to a wiring issue.
A buildup of dirt and dust can prevent your thermostat from working properly. Cleaning it every few months can avoid HVAC performance issues due to controller malfunctions. To clean a thermostat:
If you have an older thermostat, it may have a heat anticipator. It saves energy by turning off a furnace or boiler early and allowing residual heat to maintain the room temperature. Adjusting the anticipator can restore normal cycling. This requires moving the pointer toward a higher setting if the system is cycling too frequently or a lower setting if it’s not turning on enough.
Adjusting the setting too often causes your HVAC system to work harder, increasing energy consumption. This is true no matter what type of thermostat you have. However, frequent adjustments are even harder on mechanical units. It’s best to find an optimal setting so you’re not constantly adjusting the temperature or forgetting to readjust it when you leave home or go to sleep. Or, consider upgrading to a programmable or smart thermostat.
Constant exposure to high heat can damage a thermostat. The unit should not be near a heat source, such as direct sunlight, a draft, or an appliance. To protect its integrity and accuracy, it should be mounted on an interior wall in or near a frequently used room.
Excess heat can cause inaccurate readings, affect the cycling and efficiency of your HVAC system, and increase the likelihood you’ll need thermostat repair. Consider relocating your thermostat. Or, address the problem by closing a window shade, sealing a draft, or moving heat-producing appliances (if possible).
Setting a schedule can save energy, provide more consistent comfort, and avoid having to adjust the temperature throughout the day. Programmable thermostats can be set on daily or weekly schedules based on when you’re home or away. Avoid using the “Hold” feature indefinitely because it can overwork your HVAC system.
Depending on the model, smart thermostats can learn and adapt to your behavior, while geofencing allows some units to sense when you’re arriving home and adjust the temperature accordingly. Other models integrate with other smart devices so, for example, they can lower the temperature once a smart door lock is triggered.
If the temperature keeps fluctuating, your energy bills are increasing, or your HVAC system is running more frequently, your thermostat may need calibration. To calibrate a thermostat, compare its reading with a dependable thermometer. If the readings differ by more than 3℉ after 20 minutes, check the product manual for how to calibrate the unit. Calibration techniques differ based on the type and model of a thermostat.
If your thermostat detects a problem, it may display an error code. The user manual should list each code and what it means. Common error codes indicate:
Ignoring an alert can lead to missed maintenance, which increases wear and tear. It can also lead to reduced efficiency, costly repairs, and a decreased system lifespan.
Newer thermostats have advanced features that improve functionality and can avoid the need for thermostat repair. Some of these include:
A thermostat, with the rest of your HVAC system, should be evaluated at least once a year. Your local HVAC contractor can test and calibrate the thermostat for you. They can also check the unit for issues to fix before they lead to more expensive AC, heater, or thermostat repairs.

It’s no secret that furnace maintenance can save you money. An annual tune-up can improve efficiency and avoid major repairs and early replacement. But it’s not the only way to care for your furnace. Many DIY furnace maintenance steps are effective. We’ll look at simple ways you can maintain your heating system throughout the year and some more advanced tasks to take on if you’re comfortable.
The air filter traps contaminants such as dust and pollen to keep your HVAC system running smoothly. A dirty filter can restrict airflow and strain your furnace. The filter should be replaced every three months or whenever it’s dirty or clogged. When changing it, note the filter’s length, width, and depth (it’s usually printed on the side of the filter) or measure it, as you’ll need to install a filter of the same size.
The filter slot should be where the return air duct connects to the furnace. This is usually on the side near the bottom. Open the door or panel covering the filter and remove the old one. When inserting the new filter, make sure the arrows on it point toward the furnace.
If you have an oil furnace, the oil filter prevents impurities from blocking the oil burner nozzle. A clogged nozzle can cause a misfire. The system will then shut down. Replacing the oil filter requires closing the oil valve, removing the dirty filter, and disposing of it in compliance with your area’s hazardous waste regulations. Then follow the manufacturer’s instructions for installing a new oil filter.
Dirt and dust on your furnace can get inside and make it inefficient. Cleaning outer surfaces is simple. You can use a damp cloth or a vacuum to clean the metal case. Clean the area around the unit too.
There also shouldn’t be any clutter nearby, which can inhibit airflow or make it hazardous to work around your furnace. Remove boxes, tools, or toys. In addition, vacuum floor registers and then remove them to vacuum out duct connection points as well. This can improve efficiency and indoor air quality.
Air registers throughout your home tend to collect dust, lint, pet hair, and other debris. If a register is clogged, it can restrict airflow, similar to a blocked filter. Therefore, the furnace will work harder to maintain the set temperature, so maintenance isn’t limited to the unit itself or its immediate surroundings. All registers should be removed and cleaned with a high-power vacuum.
The flue connects the furnace to its exhaust system. Remove any debris blocking it and look for cracks or other signs of damage. Any issues can cause harmful gases to leak into your home, including deadly carbon monoxide. Dirt or debris can be removed from the flue pipe by removing the access panel and using a brush or vacuum with an attachment. Reattach the panel when you’re done.
Inspect the outside of the flue pipe. If there are small holes, they can be patched temporarily with foil tape. But if there are larger areas of damage or corrosion, call a professional to repair or replace the flue.
The condensate lines of a high-efficiency furnace remove excess moisture. If they get clogged, water can back up and cause a leak. The condensate line is usually connected to a floor drain or external outlet near the furnace. To clean it, disconnect the line from both ends and flush out debris using either a gentle stream of water or a vacuum hose. If the line is clogged with mineral deposits, clear it with a mixture of equal parts vinegar and water.
Only access the inside of the furnace if you’re comfortable doing so. The inner workings are quite sensitive. They are also prone to getting dirty. With the furnace’s power and gas supply off, remove the access panel and locate the flame sensor near the burner assembly. Remove the sensor gently and clean any debris with a soft cloth or fine-grit sandpaper. Then reinsert the sensor and make sure it’s secure.
Next, remove dust or dirt from the pilot light with a small brush or compressed air. Depending on your furnace model, the pilot assembly may have to be removed for cleaning. Also, clean the ignitor, which is a critical combustion component, and check for cracks or other signs of damage. Check the wiring connections for signs of corrosion or looseness as well.

Cleaning a furnace requires time and effort and is not a simple undertaking. Therefore, you should consider hiring a professional furnace cleaner at least once a year. It can be part of your annual heating maintenance visit. Other than changing the filter, which is simple, you should rely on a trained technician for more complex furnace and heating services.
Furnace maintenance keeps your heating unit running smoothly, safely, and efficiently. It can prevent big repairs and give your furnace a few more years of life. A thorough furnace cleaning has many benefits. We’ll now look at why you need a professional to help keep your furnace clean:
Don’t wait for a professional furnace cleaner to change the air filter. Your furnace has either a disposable or cleanable filter. The product manual should identify the type, recommended size, and location. Disposable filters are pleated or non-pleated and come in Minimum Efficiency Reporting Value (MERV) ratings of 1 to 16 (for most homes, a MERV 6-12 filter is sufficient).
Regular furnace tune-ups and cleanings help your heating unit run more efficiently and improve safety and reliability. We specialize in maintaining gas, oil, and electric furnaces.

A furnace install requires lots of considerations. Relying on guesswork can result in wasting money and having a heating system that doesn’t meet your needs. A furnace is an investment that can improve your home's comfort and energy efficiency for many years. Therefore, you need the help of an experienced heating contractor. But even before you hire furnace installers near you in The Greater San Francisco Bay Area, CA, here are eight things to consider:
Repairing a furnace can save you money if the unit isn’t that old, hasn’t been serviced much, and the repair bill is less than half the cost of a new unit. If your furnace has reached the 15- to 20-year mark, consider replacing it. Are you looking for a higher-efficiency model and to save on your heating bills? Then, replacing your furnace can help you achieve your goals.
Since efficiency ranks high in importance, you want to consider the energy-efficiency rating of any new furnace you buy. It is determined by a product’s annual fuel utilization efficiency (AFUE) rating. Today’s mid-efficiency units have an AFUE of 80% or higher, but a high-efficiency furnace can have an AFUE rating of as high as 98.5%. Generally, the higher a unit’s efficiency, the more it costs upfront, but the more you can save on long-term energy costs.
Also, you can save with tax credits and rebate programs for homeowners who invest in energy-efficient upgrades.
A furnace’s size can refer to its physical dimensions (the unit must fit in the available space). However, it generally refers to the unit’s heating capacity. The required capacity depends on your home’s square footage, but a professional will include other variables in a heat load calculation.
An undersized furnace won’t provide enough heat and will run longer to compensate. However, an oversized unit may not run long enough. Either way, energy consumption will be higher and the furnace can wear out faster.
Find the ideal location before a furnace is installed. This is an area with enough airflow and that’s properly insulated. There must also be an electrical outlet nearby to power the furnace and access to a vent leading outside. Consult with a contractor regarding necessary updates, even if you are replacing an existing furnace.
A furnace must also be placed in an area where there are no flammable items. If there are cleaning products, paper, laundry, wood scraps, paint, sawdust, or gasoline in the furnace room, remove these, so your furnace doesn’t become a fire hazard.
Before installing a new furnace, have a contractor evaluate your ductwork. They’ll look at whether your air ducts are properly sealed. If not, energy loss will be a problem, no matter how high the furnace’s AFUE rating is. A professional can seal ducts to minimize energy loss. They can also clean dirt and debris if necessary, which could otherwise reduce a furnace’s performance and efficiency.
Drafts and heat loss can cause dramatic temperature fluctuations between rooms. An increase in your electric bills is also likely. If your home has insulation issues, a heating contractor can evaluate and upgrade wall, ceiling, and attic insulation. They can also wrap the furnace in insulation to improve its performance and efficiency. Sealing gaps around windows and doors can also help as it can stop air from escaping.
If uneven temperatures are common in your home, a zoning system may be the right upgrade. It can help control how heat is distributed. Such an upgrade should be considered during a furnace install to ensure the equipment is compatible. Zoning systems typically require multiple thermostats throughout your home. A technician can help find a programmable or smart model that serves as a centralized hub for the entire system.
Zoning also requires air duct upgrades, including installing dampers. These act as valves to control how much warm air reaches each room.
Installing a furnace has safety implications. Make sure children don’t have access to the area where the unit is being installed. Technicians will be moving heavy equipment and using power tools. Shut off the gas line and circuit breaker for your furnace. If you can, do so before the contractor arrives so this step isn’t accidentally forgotten.
High-quality installation is the first step to having a safe, reliable, long-lasting furnace. At Trio Heating & Air, our licensed heating professionals have the training, tools, and equipment to complete a furnace install that ensures reliable heating and high efficiency.

The Bay Area of California is a bustling hub of technology and innovation. However, some homeowners in the area may still have boilers to heat their homes. If you own a boiler, it’s important to understand when to schedule boiler repair near you. The experienced team at Trio Heating, Air, and Plumbing specializes in providing timely, reliable boiler repairs to keep your home comfortable all winter.
If your boiler is not working properly, here’s what to expect when you call Trio for our local boiler repair services.
Our professional boiler repair in the Bay Area begins with a visual inspection of your boiler, looking for signs of damage, corrosion, leaks, or other issues. The technician may open the boiler casing to look more carefully at internal components like the burner or heat exchanger. Once the problem is identified, they’ll make an official diagnosis and give you an estimate for the repair.
An experienced Trio technician addresses the problem, replaces faulty or worn-out parts, and cleans the boiler’s internal components. The burner, heat exchanger, and combustion chamber are common areas that typically require thorough cleaning for optimum efficiency. After repairs, a comprehensive test will be conducted on important safety devices like the pressure relief valve, safety cut-off switch, and gas pressure.
Once the initial repair and testing are complete, a Trio technician will test the entire boiler. This is the best way to verify that everything is operating safely and efficiently. We’ll also review some tips about operating your boiler efficiently and answer any questions you may have about the repair.
You might wonder when you should schedule boiler repair. Ideally, you should call Trio for boiler repair when you notice an issue that impacts these areas:
You might not know the signs that you need boiler repair. Look for these signs that your boiler requires professional attention:
Odd noises like banging could indicate that the boiler’s circulating pump is malfunctioning, causing it to shake inside the casing. Another common cause for strange noises is buildup on the bottom of the tank, which causes it to overheat and run less efficiently. Whistling noises could be due to limescale buildup, low water pressure, air trapped in the system, water flow issues, or a defective part. No matter what, if you notice strange noises from the boiler, contact Trio for repairs right away.
Boilers are designed as a closed-loop system, meaning water should never leak from the unit. If you notice a leak or water pooling around your boiler tank, it’s a sign you need professional repair. Water leaks may be due to a faulty valve or seal, high pressure, loose connections, corrosion, or a damaged heat exchanger. The trio team is available to help, so call us right away for emergency boiler repair if you notice a leak.
If your home’s heating system is not heating evenly, you’ll notice cold “zones” that compromise your comfort. Uneven heating from a boiler may be due to blocked pipes, circulation pump issues, or problems with the thermostat. Occasionally, uneven heating is caused by an incorrectly sized boiler that’s not appropriately sized for your home.
The pilot light is an important part of your gas boiler. If it suddenly won’t light or if you notice it produces an orange or yellow flame, you have a pilot light issue. A dirty or faulty thermocouple, issues with the gas regulator, or a blocked opening near the pilot light flame might cause this issue. If you suspect a problem with your pilot light, turn off your boiler immediately and call us for help.
A sudden spike in your winter energy bill could mean an underlying issue with your boiler. Dirty filters or clogged components, leaky air ducts, or unoptimized boiler settings can all increase your boiler's energy consumption. Other causes might be limestone buildup in an electric boiler or outdated equipment reaching the end of its lifespan.
So, how often should you service your boiler, and is it better to repair or replace an old boiler? Have your boiler serviced by Trio Heating, Air, and Plumbing experts at least once a year to keep it operating reliably and efficiently. If something goes wrong, we’ll come to your home and make repairs. As for the typical boiler repair costs, you’ll pay less for minor issues and more for complex repairs requiring the replacement of major components.
Here are some examples of times when it’s better to upgrade and replace your boiler with a new one rather than repair it:
