"I had an emergency with a leaking water heater all over my basement. UGI did not get back to me after THREE attempts over two days of leaving my info with them. I decided to call a plumber instead. I believe I spoke with Jason, and he sent two of his team members out within 30 minutes, who checked out my situation and had a new water heater at my house 20 minutes later. Excellent service, friendly employees, and fair price. Highly recommend."

"Universal Air Heating and Cooling recently installed new air conditioner and gas furnace. Smooth process from start to finish. Bill was very knowledgeable and honest about what I needed. He provided options and did not oversell additional equipment like other companies. His team installed the new systems in a timely fashion. They too were knowledgeable and were eager to teach me. They were careful while in my home and cleaned any debris. Pricing of new system was very fair for Trane. Thus far, happy to use this company and would recommend to a friend or family member absolutely."

"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"HL Bowman came through when we needed them most. Our AC failed on the hottest day of the year, and they had us back up and running with a full new system installed the very next day. The technicians were knowledgeable, professional, and honest. They explained our options clearly and never pressured us into anything we didn't need. We felt confident we were getting quality equipment at a fair price. HL Bowman only carries best-in-class equipment with a variety of options across different budgets. In a stressful moment, they made the whole thing painless and smooth. Highly recommend."

"Provided excellent and on time service. Had my gas valve replaced, knew exactly what he was doing with no hesitation. The price he charged was fair, and exactly what was quoted. Requested he come back in spring to service my ac unit. Thank You Matt. Eric K."

"I hired NS JOHNSON to install a Climate Master Tranquility 30 geothermal heating and air conditioning system. Their work was very professionally done, and spot on the budget. The installation took a day an a half. The outdoor temperature was in the low 30 degree (f). On completion of the first day they activated the system to assure we had heat for the night. They completed the installation the next day. Iâ  m very impressed with their work and would recommend them to anyone needing this service. They will continue to maintain the system on a yearly basis. I plan on using them for other services."

Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.
