"We came home from an outing on a Sunday night and found our air conditioner not working. I found John Mullen on Angie's list and liked the reviews. I contacted John and he asked me about my schedule on Monday. He fit us in on Monday morning. I wasn't home but my wife was. She said that John was so nice that she assumed that he was a friend of mine. I told her that I never met him before. He fixed the air conditioner and I am relieved that it didn't cost us a ton and we avoided 85 degree heat with an air conditioner. I would use John again. He was dependable, came out with in 12 hours of being called, and my wife does not always comment on how nice someone is unless it is absolutely true. Thumbs up for John Mullen, I have just found a go to guy for everything!"

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"A great company, from the estimate to the install they were on time, informative and very professional. I really think I could not have found a better group of professionals to replace my current heat pump and air handler. Kudos to this company, I highly recommend you give them a shot at your HVAC needs. If their service is as punctual and professional as they have been for the install, I'm not sure you could find a better fit. Thank you Air Systems Mechanical and please say thank you to your team of guys for me who installed my system, they were outstanding! I found my go too for all my HVAC needs."

"ARS stands by their word! Customer satisfaction and a good quality of work is important to them. They will do whatever it takes to correct any customer or equipment issues. Mark is an amazing HVAC technician. He knows his stuff and has proven to be trustworthy in his heating/cooling system knowledge and repairs. When I had a recent burdensome furnace ignitor issue arise. ARS was as puzzled as I was. They assured me that they would do what it took to identify and troubleshoot the problem. They did just that!!! I thanks ARS for their loyalty to good and honest customer service!"

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.

Heating and Air Conditioning questions, answered by experts

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
