We have been using A-1 Guaranteed Heating and air now for quite some time. They actually installed our heating/air conditioning unit about 10 years ago and we have a contract with them. They have always been very considerate and timely. I have dogs that I need to lock up when they come so the technician always calls ahead. When we need service they have always gotten to us very quickly. I definitely recommend them.

I had scheduled a tune up of our furnace on Nov. 19 and the technician was suppose to arrive between 11 and 1. At a little before 11, I receive a call from Brian and he says he will be doing the service and that he is 10 minutes out. Promptly at 11 he arrives, which I truly appreciate as no one likes waiting. I'll keep it short, but Brian did a thorough inspection of the unit, found what issues were there and then went over them in detail with me regarding the unit. What I liked is that he didn't try to sell me anything, but told me what to be aware of and, in the future, they can repair/replace

I have been using A-1 for several years now and have been very happy with their service. I'm on their Kasey club plan for my heater maintenance. I recently replaced all my heater air ducts that were failing and the entire process was flawless from the initial inspection by Kirk who is so knowledgeable, friendly and quickly responsive to later questions all the way to completion. Kenya in the office called with the schedule which consisted of 4 separate appointments and emailed as well. The abatement team arrived on schedule but a few hours earlier than planned which was fine since we were

Ever aspect of my experience with this company, from the initial estimate, my contacts with the main office personnel, the installation itself, and the follow-up wireless control, for my new heat pump system was absolutely top notch. Matt, the project manager, was especially helpful, knowledgeable, and responsive throughout the entire process, and an absolute pleasure to work with. I would recommend this company without hesitation to anyone in the market for a new HVAC system.

A-1 Installed heat-pump (for cooling and heating) in our house.
All the process was pleasant and professional, from the first interaction with Kirk, to the office staff and the crew, Roger, Edgar, Tyler and Davis.
The crew kept the house clean, during the job and after the work was done.
Kept mask on.
Answered all questions.

This is an updated review, Krissy personally reached out to me and set things right.
Even though I did not complete my service with A1 the owner made things right by providing me a 100% refund of what I gave A1 for the initial estimates.
Just based off the owners care for the customer I would recommend this business.

We have been customers with A1 for over 35 years. Each job and upgrade they have completed for is is handled perfectly. One furnace had an odd vibration that just could not be locate. One day the installer shows up and says he has an idea what was causing vibration. He did his magic and found the problem, a simple fix was the answer.
Today Brian came by for the semi-annual checkup. He knows where everything is. No issues. Will see him in December.
A-1 is the best there is and they are a longtime local business that does a lot in the community.

I just had Jacob come out and repair our aging AC unit. He was was very thorough and efficient and fixed the problem quickly while pointing out areas to pay attention to to help me prolong the life of this unit within reason. He was so great that I signed up for their discount program (small monthly fee) which saved me money on today's repair.
I've had A-1 out here a few times over the past couple of years and each time the tech was everything I could have asked for. This company employs good, competent, friendly, trustworthy people from everyone I've interacted with. I give them

Let me start out by saying I've used plenty of HVAC companies and in my opinion, none have compared to A-1 Guaranteed. I've finally found a company that I can trust with maintaining my HVAC system.
However, the real shout out goes Jacob! The technician that arrives on-time and has been keeping my system running.
As aforementioned, Jacob arrives on-time which is why he doesn't have to rush to get the job done. As some may know, it's a process to ensure your HVAC system is safe and up-to-par and even moreso when you have a very old HVAC system, as I have.

I hired A-1 Guaranteed Heating & Air to install an air conditioner for me last summer. I'm very satisfied with the job they did. One of the programs they offer their clients is to go on a monthly "subscription" plan with them and you get your air conditioner as well as heater serviced twice a year. There are additional benefits with this program as well. I just had my second service and continue to be very impressed with this company from the people working in the office to their technicians. Brian was the technician and he did an excellent job. I would definitely recommend this company.

Great service, friendly installers! Had a rough road to getting a new ac unit put on after getting scammed by another company I finally found A-1 Guranteed and they came out promptly and installed a new unit for a quarter of the cost of my costco estimate. If anyone needs hvac service this is definitely the place to call. From kirk coming out to quote me a price to the installers Victor and Jon, the whole process was amazing. THANKS SO MUCH!
