"Very good. This was our first time having this done so we didn't know what questions to ask to get a complete estimate. Because of this they added extra services to ensure we would be happy with their work. Very polite and clean. Would definitely hire them again."

"Took a few weeks to get the appointment scheduled. They were a few mins. late showing up, but called to let me know, which is much appreciated. Work was completed in a timely manner. I was not there to witness the work, but my husband was and said they were professional and thorough. Pricing seemed to be very negotiable. I paid $175 to have 10 ducts and one main done, but then saw an ad in the QC Times for about half that price the next week. Oh well. They also offered the duct sanitizer which I declined."

"It was physical. The workers were really nice along with the owner of the company. The price was fair. It was not a bargain but it was not absorbent either. They are reliable."

Heating and Air Conditioning questions, answered by experts

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.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.
