Posted on Crystal FarmerTrustindex verifies that the original source of the review is Google. I’ve used Montell Heating and Air for both air-conditioning installation and spray insulation in my attic, and I’ve been very pleased with the results. Frank Monroy, the owner, is knowledgeable, professional, and easy to work with. He took the time to explain my options and made sure the work was done right. The AC units he installed have been running great, and the spray insulation made a noticeable difference in comfort and energy efficiency. It’s clear that Frank takes pride in his work and stands behind it. If you’re looking for a reliable Heating and Air HVAC contractor, I would definitely recommend calling Frank at Montell Heating and Air. Crystal F.Posted on Kimberly OviedoTrustindex verifies that the original source of the review is Google. Francisco is absolutely wonderful! Highly recommend!! He did the install on our new home. He has since been back for routine maintenance to keep the systems in best condition. We did have to do one repair and he made sure TRANE covered it! Great man and great company!Posted on mike luTrustindex verifies that the original source of the review is Google. My impression of this company is of an excellent status. Prompt and knowledgeable service on my thermostat that apparently died out. Very professional and I’ve even suggested to my job about their company and service! My boss has since contacted the company for handling 4 stores hvac systems. Hopefully it’ll all work out well for this company as well as it has for me. I’ll keep Montell as my personal ac& heating company for sure! Thank you so very much!Posted on Ranieri paivaTrustindex verifies that the original source of the review is Google. "Top-notch service from start to finish! Francisco was professional, efficient, and knowledgeable. He diagnosed the issue with my AC unit quickly and provided a fair quote for the repair. He explained everything clearly, and got my system up and running in no time. Highly recommend for all your heating and cooling needs! 5 stars isn't enough - I'd give them 10 stars if I could!"Posted on Maceo WoodwardTrustindex verifies that the original source of the review is Google. Hottest day of the year and our AC stopped blowing cold. Called Montell in the morning and they were able to squeeze us that afternoon. The whole visit took a little over an hour and we were back up and running!Posted on Ryan & Sarah GibsonTrustindex verifies that the original source of the review is Google. Francisco and his team were wonderful! He responded quickly to our call, answered all of our questions with details to help inform our decision, and provided us with several quote options once we decided a replacement was the way to go. He has been great to check back in once the install was complete as well to make sure everything is going well. I would highly recommend their services!Posted on Carla WhiteTrustindex verifies that the original source of the review is Google. I highly recommend Mr. Monroy at Montell Heating and Air. He came over promptly to assess the issue and was very professional. 10 out of 10 !Posted on BRIAN LEWISTrustindex verifies that the original source of the review is Google. We called the company at about 1:00p on the 4th of July, with one of our units not working & 85 degrees registering on the thermostat upstairs (and rising). They were in and out by 3:00p, with the unit working and blowing cold air. Also, the technicians were very knowledgeable & professional. Outstanding service all around. Highly recommend this company!!Posted on Saida AliTrustindex verifies that the original source of the review is Google. Frank was very kind and professional. Affordable, so I will use him again.Posted on Todd DTrustindex verifies that the original source of the review is Google. Our 24 year old AC unit bit the dust around 5:00pm on Tuesday this week. Our neighbors referred us to Montell, and Francisco came out to our house the same day. He clearly explained what was wrong with our system and we both agreed I would need a new unit and it would be a good idea to replace our limping 23 year old furnace as well. Today, less than 48 hours later, we have a new AC unit installed along with a new furnace. Francisco and his team are extremely knowledgeable and skilled in their trade. He can answer any question, responds quickly to communication, and him and his crew were punctual on our appointment day. I would happily refer Francisco and his team to anyone with HVAC needs. Thanks again!
