"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"We were having issues with our current furnace and decided to purchase new equipment versus putting repair money into an obsolete one. Due to the unreliability of the old unit, we wanted the new furnace/AC installed before we went on vacation.  They arrived on time, and completed the work in the time frame promised. All the work was done to the highest quality, and exactly as promised. This work was done on a cold day, and with over a foot of snow around the house, including around the old air conditioner. With the cold temps, we were very happy the total job was done in about 6 hours. The equipment is working extremely well. TR Miller took away all the old equipment, and did a good job of explaining the operation of the new furnace, thermostat, humidifier, and air cleaner. I would highly recommend this company for any heating and cooling work.

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward. He came today as promised and found that my thermostat only needed batteries, but my system was otherwise fine. He is very good and extremely honest and informative."

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"

Heating and Air Conditioning FAQs, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
