"Noah figured out my air conditioning problem when others tried and failed. Friendly and knowledgeable."

"I originally hired Temperature Pro for my AC/Furnace maintenance. Every time they come I get more than my money's worth from their mechanics. Everyone is not only kind, but very knowledgeable. They always offer me multiple solutions (including usually one that would cost me no money) when they find small issues. The worst moment at my house came on Dec 23, 2023. Furnace went out as we had the horrible snow storm and we were supposed to host a holiday party. Shawn from TP made sure to work me into the schedule that day after facetiming me to see if he could detect an easier fix that wouldn't require him to come out. Needless to say, he made it in time, got it fixed and no guest knew the difference. I cannot recommend Temperature Pro enough!"

"Service Professor was up front and honest right from the start. We had our vintage 1985 gas furnace replaced with a 92% efficient new model and air. While they were here they also replaced our water heater ( also 1985 vintage ), and an electrical upgrade. Now were "up to code"."

"Jordan was very quick and did a great job installing a new furnace. Completely replaced the entire unit along with the air conditioning unit. Very friendly and respectful and answered all questions asked before, during and after job was completed. Very knowledgeable and explained everything in detail."

"Very good. Stuck at it. Found moisture let it dry, came back and fixed it ."

"I love it! Framing and hanging sliding doors that separated kitchen from living room. This is a project that I have wanted to do for a long time and finally got it completed. I own a manufactured home (or as it is called now a mobile home). These homes usually have unique openings and require customized or special orders. John was extremely helpful and brought my vision of what I wanted into reality. He also provided some suggestions which proved to be extremely beneficial. He was quick and efficient with his work. John framed the space from floor to ceiling. John did framing, molding and trim, dry wall (in the space above the doors on both sides), sanded and painted. I will definitely use him in the future and highly recommend this service."

"I will start with first phone call, Ashley was so professionall, and helpfull, telling me a little about the company. Hugo, removed old dishwasher and installed new one. cleand up after he finished. job went very smooth. I own 4 apartments on Lake Bella Vista, I will be using Qualified Maintenance again. Thanks for Great job James Y"
