Cal's Air Conditioning & Heating's website states it has been in business 32 years and lists a service area of Derry, Windham, Salem, Londonderry, Hooksett and Bedford. It holds an A+ grade from the Better Business Bureau. A recent Google reviewer says Cal came out early to accommodate their schedule after five days with no AC and multiple people trying to fix it, and fixed the issue within 30 minutes. A recent reviewer also calls the company professional, with great communication and a reasonable estimate and pricing. In a 2025 review, the reviewer said Cal's had earlier determined their AC, which was only blowing hot air, had a blown capacitor, and was in and out for about $100. In that 2025 review, they said Cal's later upgraded their AC to a three zone mini split with a new more efficient condenser for the high velocity system on the second floor, and performed the work in less than 5 hours. A separate 2025 reviewer said Cal quickly diagnosed the problems, had the tools, electrical supplies and replacement parts in his tool bag and/or van, and got them up and running fast while other services were booking 2+ weeks out. In a 2024 review, the reviewer said Ernie serviced their equipment, both AC and heat, diagnosed and trouble shot the problem, and explained the technical issues in layman's terms. That 2024 reviewer also said that when their ACs went out one hour before a house full of guests arrived, Ernie was at the house in 30 minutes and fixed the issue within 30 minutes.

Professional, great communication and reasonable estimate and pricing! Highly recommend!
Highly recommend. Was able to come out early to accommodate my schedule. After five days with no AC, and multiple people trying to fix it. Cal came out and fixed the issue within 30 minutes.
We first called on Cal’s, a few years ago, when our AC was only blowing hot air. I was expecting a huge cost to repair. Cal’s promptly arrived and quickly determined is was a blown capacitor. In and out for about $100 when I was anticipating several hundred. Fast forward to last Thursday. We had decided to upgrade our AC to a three zone mini split, and a new more efficient condenser for the high velocity system we use for the second floor. In our minds, there was only ONE company to call. Cal’s came out with less than a two week lead time to get on their schedule. They performed the work in less than 5 hours. Right now we are sitting in our house, nice and cool, while it’s 93 degrees outside. One of our dogs was so cool, her nose was running! We have found, through our experience, that Cal’s is a very trustworthy, honest, prompt company with reasonable prices and expert service and installation.
Cal saved us! It's supposed to be 100 degrees tomorrow which would be rough with no A/C. Cal quickly diagnosed the problems, had all the tools + electrical supplies + replacement parts in his tool bag and/or van (so no trips to the warehouse & back), and expertly implemented a fix. We can't thank Cal enough & would heartily recommend his service to anyone. Another important detail is that other services were booking 2+ weeks out. Cal was able to get us up & running fast. 5 stars!
Highly recommend without reservation. Cal’s is a top notch, reliable business with expert level techs. I had the pleasure of the owner (Ernie) servicing our equipment (both AC and heat). He was patient, diagnosed and trouble shot the problem, - all while being patient and explaining the technical issues in layman’s terms. The prices are very fair and reasonable, and are conveyed in quick turn without surprises. We recently had our ACs go out one hour before a house full of guests arrived. I texted Ernie in a panic and he was at my house in 30 minutes and fixed the issue within 30 minutes. Grateful, doesn’t even come close to explaining it. This type of customer service and high technical skill is rare nowadays. This business is exceptional.
