"Sam the Air doctor took time out of his very busy schedule to come and help me out with my thermostat. It took him seconds to figure out what the problem was with it. Not only he fixed the problem right away but also gave me advice on how to keep my ac unit working the way it should. His prices are very fair. Never felt like he was charging more than what he should for his work. From now and on we will call anyone else. All we need is our Air Doctor. Very happy client over here. Thank you again."

"My AC stopped putting out cold air so I messaged Guerrero's via HomeAdivsor (based on the recommendation of a friend) and he called me THREE MINUTES LATER and was able to come to my house THAT afternoon. He gave me a 1hr window and was there at the beginning of it. He had our unit fixed and running within 30 min. Very kind and knowledgeable. I would definitely recommend this company!"

Air Conditioning FAQs, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
