"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."

"Because our AC was not working and you guys were busy and our scheduled install date was a week away, John Yost had a service tech come the next day and try and fix or charge our old AC, It didn't work but that was very nice. Our new AC was installed by Greg or Craig (forgot his name). He did a great job. Then we had a heating flew problem that leaked water from a heater install from 2006. John another service tech came out at no charge to us and replaced the defective elbow. You guys are the best."

"We have worked with Jeff for years. He has previously installed full furnaces and air conditioners, and two prior mini-splits at our house. He just used him again to install a third mini-split. As always, he was responsive and easy to work with. His crew are very polite and professional. They work very cleanly, leaving no dirt at all in my daughter's room after installing the mini-split. They balanced the needs of the equipment well with our desire to conceal any lines as much as possible. I would absolutely work with Jeff again."

"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

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.

Bought my new furnace from them a few years ago and North Pittsburgh Heating canâ t be beat for pricing, quality and service. Dan was out today for a furnace check and small AC fix, and he was absolutely wonderfulâ so nice, knowledgeable and took care of everything quickly and thoroughly. Great company and people for all your heating and cooling needs!"

"Water had been pooling in front of my garage by the storm drain.  I called and they were able to come out the same day.  The service technician confirmed that the drain was blocked by ice and that the water would eventually stop pooling when the ground/ice finally thawed after the long cold winter we had experienced.  Weeks later it thawed out.
The technician was polite and answered all my questions. I would recommend this company and have continued to use them.

"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."

Air Conditioning FAQs, answered by experts

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.
