"From soup to nuts, the entire experience was made easy for us by the company. The salesman, Nick, came out to see us the day after my system kicked the bucket, and after checking out the system, he presented me with a few different options, and without using fancy words, explained everything plainly and easy for me to understand. After I discussed things with my wife, we called him a few hours later to give the go-ahead, and he had us scheduled just 2 days out. The installation team arrived promptly at the scheduled window, and took care to treat our house like it was their own. Drop cloths were used to protect my flooring, and after the job was done they made sure to remove all the debris from the job so nothing was left. After the job was done, the job foreman took me around and showed me everything that they did and explained the function of the system, and when I had questions, they explained plainly and without complaint or exasperation. They treated me and my house with the utmost respect. I highly recommend this company for any HVAC needs anyone might have."

Customers say: Quick response

"I cannot recommend this cleaning company highly enough! I hired them to do a deep clean on a three-story townhome to get it ready for the rental market, and they exceeded every expectation. Preparing a rental property is always stressful, but they made the transition seamless. Managing three floors of living space is no small feat, but the team tackled it with incredible efficiency and attention to detail. Here is what really impressed me: Flawless Attention to Detail: They didn't just do a surface wipe-down. They got into every nook and cranny, from the baseboards and window tracks to the inside of the appliances and cabinets. Tackled the High-Traffic Areas: With three floors, stairs can be a nightmare to get perfectly clean. They made the stairwells and banisters look brand new. Professional & Reliable: They arrived right on time, brought all their own high-quality supplies, and worked tirelessly until the job was done."

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

Heating and Air Conditioning FAQs, answered by experts

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
