I was very happy with the work they did. Would call them again if i ever had a heating or ac problem come up.

5.0 Barbara G. Groton, MA

We canâ t say enough good things about Walleyâ s from the moment we contacted them for a quote to the final review of the project! Every step of the way for our fairly complex mini-split heating/cooling installation was smooth. Their exceptional expertise, professionalism and customer service far exceeded our expectations and experience with numerous contractors over the years (building two houses and three additions). We want to give a shout-out to Spencer who was the mastermind behind our project. He went above and beyond. We highly recommend Walleyâ s for a good value and customer experience.

5.0 Robert K. Nashua, NH

Terrific company. Follow up was outstanding. I like the furnace and a/c system they installed and I especially liked the warranty coverage they offer!

5.0 Kristen H. Nashua, NH

We would totally recommend Walley’s !!! Everyone was professional, friendly, nice and informative. We had no heat and a new born. They got us in ASAP and did a complete central air/heat with all the duct work as well as tankless hot water. They were efficient and continuously checked in on us before during and after the project was completed. Would use them again for another hvac project! Well worth the value !

Mandy in the service calling in department is so helpful and understanding. She went out of her way to make sure I understood everything they could help to get my AC back up and running( on the hottest day of 2020). She walked me through what billing would look like and who would service my unit. Tyler was at my house within a few hours and knew exactly what was wrong by my husband just explain what happened. He looked my whole unit over and had the part done in less than 30 minutes. He told me my how long it would take for my house to cool down. Both of these employees has made me a Walley's Heating and Air Condition client if I ever need services. Mandy and Tyler was exceptional kept us informed every step of the way. I will also send neighbors and friends to let.

David L. B., Adam P. L., Daniel J. C., and Christian E. F. at Walley's Heating & Air Conditioning, were all professional, responsive & punctual throughout the installation process. They removed & replaced our 30 year old central AC, leaving the installation better than the original. Their quote was competitive. They covered our hardwood flooring to protect it while the job was underway. They were responsive to our families concerns while the final details such as pad type, compressor & air handler placements were detailed. The entire crew was punctual for every visit.

5.0 Daisy L. Nashua, NH

They are really professional. From the time Dave came in our house to explain and advise the furnace that suits our need and budget, to the installation, after project inspection, the whole crew showed the highest standard of workmanship I have ever experienced. Definitely will recommend them and I will hire them again in the future.

5.0 Melissa I. Windham, NH

I've worked with a lot of contractors - and this company is by far TOP NOTCH in their professionalism and service. Super responsive and accommodating during the quote process, always on time, courteous during installation, and the follow-up afterwards to insure satisfaction is unmatched. Really cannot recommend this company more. By far the best home service company I've had the pleasure of using. You will not be disappointed.

5.0 Esther B. Nashua, NH

Exceptional customer service. Pricing out beats competition in HVAC. Nate Nick we are punctual, knowledgeable, professional, neat, respectfully and left my home spotless.

5.0 Michael W. Amherst, NH

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
