Furnace Repair in Wylie, TX 75098

“Had a service issue with our older Goodman Gas heater. My son had provided an exemplary recommendation for Montgomery, and I no longer had an HVAC company that I felt like we could trust.
So, I called, and received same day service. In fact, the technician showed up a few minutes early!
He asked some questions about the trouble I had, then proceeded to isolate, repair, and test. I know a little bit about HVAC, Duane (hope I spelled that correct) could see I was curious, so explained what the issue was, and how he was going to repair. While he was cycling the unit he had repaired to various temperatures to insure it was turning on and off correctly (and I was impressed with this), he asked about the other unit (which we had troubles with previously). Again, he described what he would try to do~~and just like the 1st unit, did what he said he would do!
Pardon the expression, but Duane knocked my socks off with getting it up and running too!
(It had previously been worked on by two different techs/visits from another company, and they wanted a small fortune to get it going, with new equipment. Even as it was, I paid for labor with them that had still left me with a non functional unit). Duane had it running within an hour.
Found a new HVAC company, and Tech! Wow. So impressed. I will continue to get service with Montgomery, and when our equipment is aged and needs replacing, I KNOW where I am going to go. Obviously an extremely competent and professional, Duane stands out. And Montgomery, for having folk like this in their employment, and being able to respond so quickly.
Thank you Duane. Thank you Montgomery.”

Air Conditioner Maintenance in Allen, TX 75002

“Montgomery HVAC is the company to call when you need someone you can trust.
We have lived in Allen for nearly 18 years. During that time we have encountered companies which will try to upsell to the extent that they have unplugged a system to make us believe we needed to a new unit.
You will never have that problem with Montgomery, They are honest, prompt, respectful, efficient and very capable. They will provide options and will always stand behind their work. Call Betty, she'll get someone on the job right away.”

“Dwayne came by today ahead of schedule to complete a tuneup on both our A/C units. He found server all small things that were affecting there operation which has now resulted in both units cooling much better. He was very knowledgeable and professional. Will definitely be using Montgomery from here on. Thanks to Betty as well for her help in getting us scheduled so quickly. 👍😁👏”

Air Conditioner Maintenance in Plano, TX 75025-6300

“The appointment was scheduled for 2PM. Dwayne arrived at our home 1:55PM. That's about a close to the appointed time as one can get!!! Dwayne attended to his duties commencing with the unit in the attic and than the outdoor unit. We discussed the service that was performed as was documented on the check-list. Dwayne appeared to be very efficient in his work practices and was enjoyable to talk with. I will anticipate continuing our working relationship with Montgomert HVAC in the future and will in-fact attempt to have Dwayne respond to any of our HVAC related needs”
