"Mat and his team are consistently awesome. The first couple years we owned our home we struggled to find a reliable HVAC company to help us. Once we found Home Mechanix we were so relieved, and have never looked back. They’re always prompt, respectful of our home and business (they’ve done work at both), friendly, and happy to explain all work and maintenance. We won’t use anyone else for our HVAC work, period."

"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."

"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."

"I work for a property management company and we had a tenant that said her furnace wasn't working (it was freezing outside) and all of my "go-to" HVAC people were unable to get there. So I called Calfo and they rushed someone out there pretty much immediately. As it turned out, there was absolutely nothing wrong with the furnace -- just the tenant. But the technician (whose name escapes me) was very professional in dealing with the tenant and only charged us for the call. I will definitely use this company again."

Heating and Air Conditioning questions, answered by experts

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.
