Professional Indoor Air Quality Services in Frisco, TX

I had an excellent experience with One Hour Heating and Air Conditioning of Frisco! Parvez Ahmed arrived promptly, was professional, and extremely knowledgeable. He took the time to thoroughly assess the issue, explained everything clearly, and ensured the work was completed efficiently. What stood out most was his attention to detail and commitment to providing top-tier service. It’s clear he takes pride in his work and genuinely cares about the customer experience. If you’re looking for reliable, skilled HVAC service, I highly recommend Parvez and the team. Outstanding service from start to finish.

Fast, affordable, helpful, and knowledgeable - I can’t recommend One Hour enough! I have a ductless mini split system in a property that hadn’t been serviced in several years so they were pretty dirty, but Ali took great care of everything. I am located in Denton and even though the company is Frisco-based they got out here on time with no issues. Ali was very informative and made sure I knew how to clean the outside condenser and do the filter changes on the inside split units for upkeep between professional maintenance needs. I was worried there would be extra charges or issues with the system because of how long it had been since the last maintenance, but Ali did a wonderful job taking care of everything and explaining any questions I had, and the price was exactly what I was originally quoted. He was very courteous and respectful of my home as well! I appreciated the text I got beforehand with a picture of the technician so I knew who to expect. As a woman it can be odd to have men come into your house that you do not know, especially when you are alone, but I felt very safe and reassured with how One Hour and Ali handled everything - very professional and considerate. I have already suggested this company to a few of my friends and will be using them again for this property and others. Thank y’all for doing a great job!

I was looking for some reliable AC guys to looks at our units before the summer kicks in. Ali was the AC engineer and he is amazing with his knowledge and expertise on the system. He gave us 3 options to address one of the older units and he is extremely transparent on the pros and cons of those options.

I recently had my air ducts cleaned and I’m extremely satisfied with the service. The team was professional, punctual, and very knowledgeable. They explained the entire process clearly before starting and took great care to keep my home clean throughout the job. What really stood out was their honesty and transparency—no hidden fees, and they didn’t try to upsell unnecessary services. Overall, it was a smooth and hassle-free experience. Thank you Mr. Parvez for helping us.

Just purchased an old house and requested a service check. Adam Matacale of Frisco came in and did thoroughly check the AC system and even helped me to identify the second unit and where it is installed. He explained the test results and what are recommended, patiently ask all my questions, very professional and trustworthy.

I can’t thank Ali Avesta enough for coming to my house the same day and checking my A/C and HVAC units. He was extremely helpful and very knowledgeable! He did not try to sell me things I didn’t need and helped me understand how the units work(I’m a first time homeowner so definitely needed it) and why they do certain things. I have a much better grasp of it now and it’s all thanks to him and his recommendations. Thank you for everything! 110% would recommend him.

I recently called One Hour Heating and Air Conditioning when my air conditioner stopped working properly, and I’m so impressed with their service! They arrived within the hour, true to their name. The technician was professional, friendly, and highly skilled. He quickly identified the problem—a clogged drain line—and cleared it efficiently. He also shared helpful maintenance tips to prevent future issues, which I found very useful. The pricing was transparent with no hidden fees, which I appreciated. After the repair, my system was back to normal, and I noticed improved performance right away. What stood out most was their commitment to customer satisfaction—they ensured everything was working perfectly before leaving. I highly recommend One Hour Heating and Air Conditioning to anyone needing HVAC services. Their promptness, expertise, and dedication to quality make them a top choice. Thank you for a great experience!

I can’t say enough good things about this HVAC company! From start to finish, the entire experience was smooth, professional, and stress‑free. My technician, Guy, showed up right on time, quickly diagnosed the problem, and explained everything in a way that was easy to understand. He clearly knew his stuff — you could tell he’s a real expert in his field.What really impressed me was how fair and transparent the pricing was. There were no surprise charges or pushy upsells — just honest work at a fair rate. Guy even gave me a few helpful maintenance tips to keep my system running smoothly. On top of that, he was friendly, respectful of my home, and went above and beyond to make sure everything was working perfectly before he left.It’s rare these days to find a company that combines skill, integrity, and great customer service like this one. I’ll definitely be calling them again for any future HVAC needs and recommending them to friends and family.
