"We are beyond happy with the work and professionalism of Porterhouse Cooling and Heating. I called for an estimate and they were out the next day. Then that same day they were able to get us set up for our work. They began the project only a day later. They truly were amazing to work with and supported us throughout the process. We needed a huge job done, because we switched from all electrical to adding gas to our house along with a furnace, water heater, air conditioner, and all new ductwork. We had multiple obstacles that most people did not want to take on. Porterhouse helped us come up with solutions and were very reasonable. They were extremely hard working and did a great job with our house. We love our new heating and air systems! We also have a new thermostat that is wonderful. I highly recommend them for any heating or cooling needs!"

"They were able to send out a tech to repair our AC pretty quickly (within a few days), even though this was during a bout of unusually high temperatures. The tech arrived towards the end of the given arrival window; even though he was still within the window, they called me that day to let me know he would be later rather than earlier, which was nice. The tech diagnosed the issue, and discussed options with me and fixed it (low line refrigerant, possible leak). All that was great, and prices seemed reasonable. The only negative part of the experience is that there was an extra charge to de-ice the frozen interior coils. I could have done that in advance if I knew I was supposed to (the tech seemed surprised I hadn't, or that I wasn't told to). Maybe that's obvious to others, but it's not that big of a deal, just an an annoying extra cost."

"After the tech diagnosed the issue with the AC. It was determined that I needed to run a new line from the AC condenser on the roof to the furnace in the basement. Seeing how the line within the wall was cut. Not sure how that happened but as a service technician myself I have ran plenty of low voltage wire, cable lines, and Cat 5/6 wiring for internet services. After assisting the tech with running the wires. He wants to overcharge me. I asked him if he normally has customers assist with his work and then charge them extra money for there help. And I had to use my own drill to finish the job. I will not be recommending him for anything. Sorry bro you can keep it moving."

"I went from one outlet to three & from a floor cluttered with electrical cords to a clean space. Amir suggested additional outlets because I had created a fire hazard by using a multiple outlet power surger which probably caused the outlet & the power surger to blow out during a storm."

Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

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.
