"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."

"Steve and his team are very professional and get the job done in a timely fashion. We had three quotes on a new HVAC system and his was by far the lowest. They were wonderful to deal with and would hire them again without question."

"Francisco and his team (Ralph) did absolutely great work. If you are reading this review, book them. Your search for an HVAC contractor can stop here. I am a new home owner and had a lot of questions about my home. I am an engineer and wanted to understand the exact details of the repair.. They took the time to answer all of my questions, I had a few HVAC contractors estimate the work and they were the only ones that did not try to upsell. They explained the work to be done before and during the job. Afterwards they gave recommendations about future work that I plan to do. I would absolutely do business with them again and you should too. Note: I have no relation to them at all. I did not know the two of them before this job. I would absolutely do business with them again should their services be needed. It was a pleasure learning from them and they did quality work repairing the original issue they were contracted for. Additionally, they went above and beyond the contract to fix several other issues that occurred / were found during the job. This is the team you want to hire for your HVAC needs. They were fast, did quality work, were on time, had solid communication, and were reasonably priced. Francisco / Ralph, if you you ever need a referral, let me know. Again, great work guys. 10/10"

"Jim also replaced an aging furnace. I can't say enough good things about his operation -- prompt to respond, thorough in explaining (down to JPEGs) of problems that need attention, dependable service, good pricing. He recently fixed an HVAC thermostat problem in my condo that had most likely been caused by my tenant's well intended intervention -- with no charge. I would highly recommend him to anyone. Honest, knowledgeable, and a pleasure to work with."

"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!"

"I talked with the rep on the phone about the vents and my 2 A/C units. We agreed on a price based on the fact the 2nd AC only covers the master bedroom. The tech called a hour before he was to arrive. He was very professional and got right to work. He was able to clean the vents, clean out the dry vent and santize in just under 2 hours. They are very reliable and do a good job. I would definitely hire them again. They dryer is definitely drying much better!"

Heating and Air Conditioning questions, answered by experts

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.
