Annual Tune-up #78034 We had A1 install a new HVAC system in our home last year and today was the first annual service for our furnace. We were impressed that the service tech arrived right at the scheduled time. He was extremely thorough and took the time to explain how we should have our humidifier set for maximum comfort. He was very neat and did remove his shoes before entering our home. Thank you for the great service John! 

Business response:

John is a great guy - I think we will keep him!! Thank you for taking the time to post a review!

Replace old furnace and AC A1 responded promptly to my inquiry and provided all the info required to make an informed decision. The installers were prompt as was the actual installation. They were informative as to what they were doing as well as their progress. They were also polite. Definitely not a pair of bulls in a china shop. Their work was excellent and they made sure to clean up after every step in the process. I would have no hesitation in recommending A1 to friends. 

Business response:

Thank you for the great review!

We have used A-One for 12 years and will continue to use them for our heating/air conditioning needs.

Thank you very much for being an A1 customer for such a long time. We appreciate your business!

New air conditioner and furnace Our 28 year old air conditioner was barely working by the end of the summer, so we decided to get a new one, while also considering replacing the 19 year old furnace at the same time. Dave from A1 came to our house within four hours of my call to A1 to provide a quote. He also included information on the government rebates we were eligible for. We decided late on a Thursday night to proceed with A1 - first thing on Monday morning, the installers were at our house installing our new units. They... read more
