What size air conditioner do I need?

Ask us for help in determining the size. Today’s air conditioners are more efficient than older models and don’t need to be as large to deliver the same benefits. We can calculate the best size for your home.

What’s the average lifespan of an air conditioning system?

The average life is between 10 and 15 years. Life expectancy can hinge on the amount of usage, how well your air conditioner is maintained, and the climate.

How do I tell if I need a new air conditioner?

Unit age and energy costs are the two biggest signs that your system needs replacing. If your current A/C is 10 or more years old or needs frequent repairs—or your energy bills are sky high—it’s probably time to upgrade it.

Why is there ice on my air conditioner?

It could be due to low refrigerant, bad air flow, or a busted fan. If you find ice on your unit, it’s best to have one of ComfortAire’s experts repair it—continued improper use could damage the compressor and force costly repairs.

How often do I need to schedule A/C maintenance?

Just like your heating system, your air conditioner needs a yearly clean and check. Schedule a routine appointment in the spring, just before the warmer weather arrives, to make sure it’s ready for the season.

Is “auto” or “on” the best setting for my thermostat fan switch?

When running your A/C, both fan settings do different things. Setting it to “auto” will help you keep cooling costs at a minimum, as the fan only runs when needed to hit your set temperature. For more consistent temperatures and uninterrupted airflow, set the switch to “on.”

My A/C isn’t running—what are my next steps?

Check the basics before calling a professional to repair your A/C. That includes testing the batteries in your thermostat, changing your air filter, checking for a blown fuse, and making sure your system is set to “cool.” If you check those boxes and still aren’t getting cool air, call our experts for help.

Is there anything I can do to improve the energy efficiency of my home?

There are many factors that can affect the energy consumption of your home, including ductwork leakage and overall ductwork condition. We have ductwork and sheet metal capabilities and offer duct cleaning, duct sealing, air duct repair, and sheet metal installation for a variety of duct systems.

Why is my system running all the time?

Check to see if your thermostat is set too high or too low. If you’re uncomfortable, call us for help.

My home isn’t cooling. What can I do?

Check the circuit breaker box or electrical panel. Are the breakers in the ON position? Check that your thermostat is ON and set to COOL.
