"My air conditioner stopped producing cold air Saturday evening, but I noticed so late that I had to wait until Sunday to try to get it fixed. I called the company I typically use for my HVAC and was told it would be $230 for them to even come to my house because it was a weekend. I completely understand a weekend being overtime, but I didn?t want to pay the additional fee so I told them I could wait until Monday to have it fixed. A technician was supposed to call me back to schedule a time for them to come on Monday, but they did not end up returning my call on Sunday. While I waited for the other company to call me back, I looked at Angie?s List to see if there were any highly-ranked companies I could use instead. John Mullen Home Repair was one of the companies I had planned to call Monday, but I noticed the hours said they were still open so I called at 6:00 PM on Sunday, fully expecting to schedule them to come Monday. John answered and said that he was on another job that he expected that to wrap up shortly and that he had another stop to make after that, but he thought he could get to my house around 7:00 PM. At this point it was about 85 degrees in my house with all the windows open, so I agreed to have him come out even if it meant an additional weekend charge. Around 6:45 PM I received a call from an employee of John?s saying he would be at my house in about 15 minutes. In talking to John, it seemed like he was going to be the one who came to my house, but I?m assuming he ended up sending someone else because he would have gotten to my house later than his estimated 7:00 PM. Having had to wait many hours for various service people to show up for their appointments, I was very impressed and pleased that they cared so much about meeting the appointment time. He showed up right around 7:00 PM and almost immediately diagnosed the issue as a blown capacitor. My air conditioner is fairly old and has actually blown a capacitor before, but the previous time it broke I used my typical HVAC company who charged me $250 for the capacitor on top of the labor and additional weekend charge (because of course it broke at the beginning of a 4-day holiday weekend where every day was in the 90s). The guy from John Mullen charged us $100 total for the capacitor and the labor. I was very pleased with that as well, so I mentioned that I?m probably going to replace my AC unit sometime in the next year and would be interested in using John Mullen. He said he noticed that the unit was older and that we could probably just run it until it dies, but explained a few of the newer units they have and the pricing for those. He wasn?t pushy at all and didn?t try to sell me on anything immediately, which I appreciated. To summarize, it took John Mullen Home Repair about 1.5 hours from the time I called them to the time they left my house after fixing my air conditioner, all for $100. I am very happy and would definitely recommend using them."

"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."

"They installed our HVAC system two years ago and they service it every 6 months. We have the furnace checked in the winter and the air conditioner checked in the spring. They are very reliable and professional and they do a great job."

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

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

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.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.
