"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!"

"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."

"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."

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.

"Very professional and high-tech serviceman. He did not rush. He took the time to diagnose the problem with the heat exchanger in our furnace. We have a very old furnace in a property we rent. He made us feel comfortable the furnace can make the winter. Would highly recommend Kennilhan. Great company."

Heating and Air Conditioning questions, answered by experts

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

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.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.
