Get directionsSupercare Inspection #78039 My parents recommended A-1 to us quite a few years ago when we needed a/c service and we found out that the company that had installed out heating and a/c equipment had gone out of business. We are so glad we did!! A-1's service is always top notch. John D came to do our heating inspection and went above and beyond to make sure all was good for the upcoming season. Thanks John!!
Business response:
A1's Supercare is an excellent program to keep your HVAC equipment running smoothly and you get an added bonus of a great license technician like John looking after you!
Repair Furnace My furnace would not work above 62 degrees. MikeB from A1 figured out what the problem was, fixed it and also made sure that the furnace was running properly before he left. I and other family members have dealt with A1 for well over 20+ years. When we have an issue or just need the annual inspection completed our preferred technician by far is MikeB. He is professional, courteous, knows his stuff and does a great job. He is also always respectful that he is working in someone else's home.
Business response:
Mike B is a an excellent representation of A1, we have many staff that have worked with us for 25+ years which means so much...thank you for posting a review!
Maintenance Program A1 has an excellent Maintenance program. Have been with them for several years. John D is always very thorough, pleasant and professional. We request John D because we are confident the job will be done right. Highly recommend John D and A1. Thanks John. 79530

79649 Hi Peter, Rolf, Mike recently conducted a service inspection of our furnace. I must say that we are not surprised with the ongoing superlative service provided by A1's service staff. Wouldn't consider going anywhere else and continue to sing your praises. Best regards.

New furnace and air conditioner We needed to replace our air conditioner and furnace due to other renovation plans. A1 worked with our schedule. Everyone we dealt with was courteous, knowledgeable and helpful. The installation is excellent - clean looking, and was done in less time than expected. Will continue to use A1! 79514
Business response:
Thanks for the great recommendation! We look forward to working with you!
A1 Air Conditioning and heating My furnace was installed some years ago by Mike of A1 after he discovered a dangerous leak in my old furnace which the previous servicing company had either overlooked or didn't check.
