We have used Tony and his employees for over 20 years. As always they respond quickly are knowledgeable, efficient, and prompt. Would never consider using anyone else.

Excellent service. They have been providing service to our residential heating and cooling systems for over 20 years. I highly recommend them!

My heater went out in the middle of the night. They came as soon as I called and got in fixed in no time. There service was fast and the tech was very knowledgeable. I would recommend them to everyone. Thank you!

Chandler is very thorough and reliable. Wonderful service from him and Guaranteed Mechanical.

I just want to say how impressed I am with guaranteed mechanical, my furnace and air conditioner has been running fantastically. I've had it for about 9 months and the results are just outstanding.

Guaranteed Mechanical has been taking care of our family and friends for 20+ years. Your HVAC never seems to go out at the perfect time, Tony and his guys always find time to fit us into their schedule and get us back up and running!

Guaranteed Mechanical has been taking care of my HVAC systems for over 15 years. In all that time they have kept everything maintained, and because of this all the equipment is running as well as it was when first installed. If you need anything from service to new install you should give Tony a call!

My House Air Conditioning wasn't working when I got up yesterday morning. Called Guaranteed Mechanical at 7:30am and they found a way to come to my house by 2:30 pm. Chris investigated and was Able to resolve the problem (burnt off lead on the Start-Up Capacitor), by installing a new Start-Up Capacitor and fixing the wiring. I was Lucky my Compressor still good.

The removal of the obsolete air conditioning units in our member clubroom was done very professionally and on time. The technicians repositioned furniture moved during the removal process and cleaned the area before leaving. We are very satisfied.

I felt they were very prompt, friendly, and honest. Chris did a thorough job of cleaning our furnace, and double checking everything to make sure everything was good and working well before leaving. I definitely recommend them!

I recently hired Guaranteed Mechanical to install a new A/C and furnace. The technicians where prompt and professional. Joe and Chris, the service techs were engaging and very detail oriented in the installation, and did a great job with clean up. Our system works wonderfully, and I am so pleased at the job they did. I highly recommend these guys for your HVAC needs!

Guaranteed Mechanical is great! Tony answered the phone right away and was able to get his team out first thing the next morning for our office's broken A/C unit! The team was here on time, and you can tell they were very honest. As a business, we had two other companies come out and provide quotes on repair and not only was Guaranteed Mechanical accurate but they had the best, most reasonable pricing. Would recommend them to anyone.

Walker did a great job! Was able to troubleshoot the issue with the AC not cooling quickly and fixed it! Yesterday was record breaking heat index of 105-110 degrees . We were cooled off in no time. I am posting on behalf of Fischer Building and Remodeling Inc.

Chandler came out the same day our AC went out when it was in the high 80's. Tony and his crew are the best at what they do and take great care of their customers. Highly recommend!
