"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."

"I talked to Nick who was good enough to send a technician out the very same day that I scheduled the service. The technician, Dan, was very prompt, thorough and friendly. He cleaned and sanitized 10+ vents, HVAC system, returns, supply lines, main line, and the dryer vent which was on the roof. A lot of Groupon deals that I looked around for have up-charges for the requirements that I had, particularly since I live in a 3rd floor walk-up in the city. With Lowe's the price that was quoted was the price that I got! I will definitely use their services again!"

"My AC died on me in the middle of the night, so I texted them instead, using the Home Advisor App...They responded before I had my first cup of coffee in the morning! They sent out Art to help me shortly after hanging up... WOW !!! Art knew right away the problem and went to his truck for the part, and it was fixed in minutes. Even before the HOT SUN started to bake my house... I am extremely grateful. They now have me as a permanent customer for both my central air and heating systems... I highly recommend it."

Heating and Air Conditioning questions, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.
