All reviews for Cal's Air Conditioning & Heating

Ernie and George were awesome to deal with and worked hard to get us on the schedule to replace our AC unit even with the HVAC buiness being straight out. Promoted, courteous and professional!!

Our AC turned off yesterday and even on a Sunday they answered our call and scheduled us an appointment for the following day! They service central AC, which is rare. Super friendly, very insightful, and reasonable pricing! We'll definitely be using them again in the future! Choose Cal's for you air conditioning needs!

Ernie was great! Found him on Angie’s list and couldn’t have been happier. I received 4 quotes for a ductless split system on my home with an air handler for the second floor and an in-law suite as well. Ernie was extremely competitive with his pricing. Ernie was on time, extremely clean and meticulous. He even vacuumed the house after installing. He took the time to explain in detail how everything worked and the most efficient way for everything to work as well. I Highly recommend Ernie, you’ll be happy you hired him.

Cal is just amazing and definitely one of a kind business as in service quality and professionalism.

I was first introduced to cals back in 2004 when I bought my home in Derry. He has never failed me at anything! From installation of my furnace, not one ac units but two over the years. He continues to reach out with a call to make sure I don't have any further questions after his work.

He is polite, kind and straight shooter as in professionalism and quality of his work and clean up afterwards. He has always quickly responded to any and all service questions and conducted repairs immediately. Not many like him and his crew left in the world. Just amazing

I highly recommend him and his services and WILL ALWAYS use his company.

Just had a great experience with Ernie and George. They just replaced our furnace because it was on it's last legs. He was able to get to us right away because my Mom was having a problem with the cold. Was very quick replacing it and was great with the price especially when everyone else we called were much higher on their price with a much longer time line to replace it with. Couldn't have gone any smoother. I would highly recommend Ernie and Cal's they're very good and caring and tells with his quality of work.

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.

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!
