"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.

"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

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
