"I would highly recommend ARS - Pittsburgh to everyone who is in need of HVAC work!! From the moment I reached out to them to install was 2 business days, and then a couple days for a follow-up visit due to additional work needed which was unforeseen prior to my new boiler installation. Each and every employee (Bob, Chris, Jay and Tomas) were phenomenal. We will definitely be using ARS - Pittsburgh in the future for when we are ready to move forward with our ductless air conditioning needs."

"John stopped one day to quote us a price, we arranged for the work and a few days later our new furnace and AC units were installed. John's helper arrived promptly, removed our old furnace and AC unit and installed the new one along with a new air cleaner, new thermostat and all new piping. The job was competed professionally and in one day. And everything was cleaned up before he left. We did have one small issue with a leaky condensate drain pipe which was quickly remedied the same day we discovered it. I would recommend John Mullen Home Repair to anyone. The best part is that he is a local business and we were really pleased with to deal with someone local."

"I have had air systems mechanical install my high efficiency furnace few years ago and recently install my central air. Their prices are lower than the rest. They are always courteous and professional from salesman to office staff. I have nothing negative to say. Always on time for routine furnace tune up appointments. A great company to deal with."

"I had the crew of Glenn, Brenden &Josiah to clean my air ducts. They were very clean and efficient. They explained everything and pointed out mistakes in the construction of my ducts with cold air returns. They also left information for UV purifier for my son’s allergies to review. I liked the fact that the work was hospital grade."

In the middle of July, when the thermometer is pushing past 100 degrees Fahrenheit, air conditioning isn't a luxury that's nice to have in Pittsburgh—it's an absolute necessity that you don't want to live without. It's obviously a disaster when your air conditioner grinds to a halt on the hottest day of the year. But it's also incredibly frustrating to deal with an AC unit that only "kind of" works and is struggling to get your house down to the temperature on your thermostat or control humidity levels. When you notice those types of annoying issues, it's necessary to get professional Pittsburgh air conditioner repair services before the problem worsens and you're left sweltering in an overheated house.

I have 8+ years experience in the heating and air conditioning field. I’m very mechanically inclined, therefore I’m quite useful to do just about anything. I’ve done everything from general around the house stuff to full scale renovation work. I would be my pleasure to do any work for you!

Air Conditioning FAQs, answered by experts

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.
