"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."

"Brian was the sales person and thankfully he was the first person of four to bid on our job. He took the time to explain what we really needed, why we needed it as well as what we didn't need and why we didn't need it. His professionalism, knowledge and ability to explain HVAC to someone who is not familiar with it made all of the difference. None of the other three companies met the standard he set. The real icing on the cake was that the TR Miller bid was also the most affordable.
Ben and his team came to install the system today. They were on time. They were very accommodating. They worked quickly, efficiently, remarkably quietly and effectively. Ben took the time to explain how everything was installed and why it was installed the way it was. He also explained fully how the thermostat and humidifier work.
Our house, inside and out, is cleaner and neater than when they began their work.
We couldn't be happier. I will actively recommend their service to anyone."

"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!"

"The service tech(Chris) was very courteous and knowledgeable. I told him before he came that the fan was running intermittently. He said he would be out in the morning with the motor in case that was the problem. Turns out the fan was fine and it was a solenoid that was bad. He could have replaced the fan and the solenoid and made more money for himself and the company. He just replaced the bad solenoid. He fixed my AC in less than half a day during a heat wave and saved me money! If anybody asked if I know good and honest HVAC place I will recommend "Generations"."

Heating and Air Conditioning FAQs, answered by experts

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
