"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."

"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 were so happy to have Sullivan Super Service (Plumbing, Heating, Cooling) come today to repair our central air conditioning unit and to service our HVAC system. Sullivan's technician, Bob Anderson, was polite, professional and experienced. We greatly appreciated his knowledge and counsel. Our AC has been out for a few days in a current hot spell, and Sullivan was the only company that contacted us. They proved the old saying that in winning, half of the battle is just in showing up and being there. We were not Sullivan customers before, but we are now! Sullivan's service was SUPER!"

"Had a great experience with North Pittsburugh Heating. After getting screwed around by our home warranty company for almost 5 weeks (Choice home warranty btw, never use this scam of an agency), I contacted Tim independently to see how quick he could come out and get us a new condenser unit. Tim came out that very day to look at it and got our AC fixed within a week's time at a very good price. The tech's he sent to our house to do the job were also very courteous and helpful, amazing company! A major breath of fresh air after the nightmare we were dealing with previously. We'll definitely be using them in the future for our HVAC needs."

Heating and Air Conditioning questions, answered by experts

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
