  • Just wanted to express our gratitude to your Technician Walt and his Service Manager for quickly getting us help and fixing our heater this Saturday.

  • Dear Hannabery, We just want to thank you for the excellent service given to us by your staff - Ian especially. He was so mannerly and careful - always putting on his booties when coming into the house. The repair to our heat pump was done in a timely manner - and we are so appreciative of your treatment to us....we know that we can always depend on you and we will recommend your company to others.

    P.S. When a company such as yours is doing everything they can to make a customer happy, then you should be rewarded with compliments and appreciation. I feel that you went above and beyond helping me get the heat pump fixed and your records were so complete that there was the warranty that was used as payment. I also want to acknowledge the two ladies that answered the phone when I called - they were both so kind and thoughtful. Be proud of your company. June

  • I want to let you know the 2 men that came to put in my new heat pump were wonderful. They were extremely professional, they were very respectful of my house and made sure it was kept clean. When they were done they made sure I understood the new system. I have been a customer for 14 years and want to thank you for all the wonderful service your company has given over the years. You should be proud to work for Hannabery!

  • Replacement of my central heat pump went exactly as I was told (1+ day). The team that was here was courteous and friendly. They took care to cover my hardwood floors where they had to pass through the house and did a great job at cleaning up. They consulted me throughout the installation about various options I had during the installation and continually updated me on progress. They did not cut corners anywhere. They even added another duct and new wiring at no extra charge on the original contract. When I had them give me a quote, I was never up-sold. I actually was the one that upgraded items (upgraded filter and humidifier system). The work outside the house was as meticulous as inside.

    • Joe Hammerstone

  • My central air/heat pump died. I got a few estimates. I was floored by how I was treated by other companies. One gave me a price and said I had to sign that day for the price, another told me they would need to rip out my ducts & drain pipes. In walks Dave from Hannabery, what a difference! He took the time to look at my old system, explained what SEER was and all of my options. More importantly he conducted himself in a friendly professional manner, as did the crew who put in my system. I have to say with all of the work I have had done, this was the best experience I have had for service, price and quality! I will be referring all of my friends, neighbors and family to Hannabery! Thank you to your entire team for all of their hard and excellent work.

  • I just wanted to let you know about my experience with your company. Recently two of your employees did a Change-out of the HVAC system in my home. The guys arrived on time, were professional and informative and finished up on time also. I had to leave to go to work before they were done but I am happy to say when I returned, my home was warm and just as clean as before they arrived. Please tell Todd and his partner that I appreciate the quality service they provided.

  • Great site! Lots of info - we learned alot about our heat pump! We especially liked the "Heat Pump 101" section. Reminded me of Ferris Bueller's day off...Anyone, Anyone.. LOL! :)

    • Paul and Karen Thieken

  • I really enjoy your website, very informative on how to maintain your own system. Prices are very reasonable on having your system serviced. It's very easy to move around your website and find what you are looking for quickly. Thanks for making it simple and very imformative ;-)

  • I want to thank you for providing a solution to our hvac problem. Our AC stopped cooling and after a search for "hvac not cooling" I was glad to find such a thorough check list to go through before needing a service call. It was a simple solution of realizing the outdoor unit was not running and doing a simple restart. We are cool again! Many thanks!!!

  • I just wanted to give you people a very heartfelt thank you for your trouble-shooting tips on the forced air furnace. My husband was off at work & I was here alone in the house when I woke up to only 52' in here. I have some health problems & can't afford to get chilled so this could have been very dangerous for me. I went through your Troubleshooting checklist & discovered that the power to my furnace was off & I was able to get it turned back on, thanks to your website tips. You people saved me from getting really sick, not to mention a costly service call if I couldn't have figured out the problem from your checklist. So from the bottom of my heart I thank you all. God Bless you. Mrs. Barb Gravel-Canada (where as you may have heard is VERY cold in the winter! *s*)

  • I was able to determine that a service call to my A/C Serviceman was necessary. My desire in looking before hand was finding a short checklist of items to check before he was called. ie reset buttons, etc. I found your site very helpful and the most easy to access simple troubleshooting questions. I appreciate your efforts to answer these querries without anything but a thank you. Well, here it is!! Thanks,John Friedman

    [Follow-up:] Please feel free to use my comments. I really appreciate the way you have transferred your businiess style of customer service [and I never had contact with you prior to this] to the seemingly "service-less" Internet. Most people want a buck for their bang, if you catch my drift.Thanks again, John Friedman

  • Thank you so much for providing knowledge and helpful information to people outside your industy, rather than just having something to sell.

  • Had a problem with my heat pump this morning. Circuit breaker kept popping. Googled it and your website suggested checking for loose wires (to the breaker). Guess what? That was the problem! You saved me hundreds! Thank you so much!!!
