"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"I sent a message through Angies List and they responded almost immediately. I was called and given a 30 minute window of their arrival, plus the technician's name. Then the technician called me when he was on his way. He talked to me then went to work and immediately diagnosed the issue (chipmunk chewed the wiring argh!). He gave me a quote which I felt was quite reasonable and the repair only took about 45 minutes. After that, we spoke further about the Hvac (it's pretty old), he said it seems to be running well but obviously has some age to it. He advised I don't need it replaced but may want to consider some ongoing maintenance. He was nice and professional and answered all of my dumb questions. I would definitely call them again.

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."

"Had an issue with a system 5 Star installed in August (7 months ago). They came out in 3 hours, and in 5 minutes realized that an electrician (separate project) had flipped off the wrong breaker. Had me up and running immediately. Cannot recommend 5 star enough for all HVAC work"

Heating and Air Conditioning FAQs, answered by experts

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, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.
