"Working with Mario was very easy and stress free. Any questions or concerns I had, he was eager to answer and or solve. The Trane system (installed 4 weeks ago, 96% Furnace and 18 SEER AC) has been working VERY WELL and so far I could not be happier. Install took two days which was expected, clean up could have been a little better but that comes with every person that comes into your house. Overall I would absolutely recommend Air Temp and Mario to anyone in need of any type of HVAC work. Very Pleased."

"They arrived promptly, entered the HVAC housing area and accessed the situation. I was glad to learn that my furnace was working fine and the smell of an electrical fire was gone. They changed the filter and suggested that I call them if the smell returned."

"No 1 Cleaners were very professional and did a good job of cleaning our air conditioning ducts and vents. Carlos was knowledgable and did a through job. However, there was one thing that we did not like. While angi said that the initial quotation was FREE, No Cleaners said that if they came to provide a quote and we decide not to proceed with the work, we needed to pay $99 as fee for inspection. This was a bit disturbing as others did not charge for the visit and initial quote. I would recommend No 1 Cleaners as they were were professional and executed very well."

"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

"My tenant reported an issue with the HVAC on a Sunday. I called Robert @ Phase II at noon on a Sunday and he had someone over to resolve the issue within a couple of hours. Great customer service. I will definitely use Phase II in the future. Thank you!"

"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

Heating and Air Conditioning FAQs, answered by experts

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.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.
