Alexander Hvac & Mechanical Llc

Alexander Hvac & Mechanical Llc handles HVAC work for homes and businesses around Plano, Texas. The local climate puts heavy demands on cooling and heating equipment, with long hot summers that push air conditioners to their limits and occasional cold snaps that test furnaces and heat pumps. Homeowners here often deal with duct issues, worn compressors, and systems that struggle to keep up during peak heat. The company focuses on straightforward mechanical service without extra layers, covering everything from routine checks to full equipment swaps in both residential and light commercial settings.

They install and replace air conditioning units along with heating systems such as furnaces and heat pumps, and they handle repairs on complicated setups that other crews have walked away from. One job in a warehouse setting finished ahead of schedule even when overtime was offered, showing they stick to the plan and move efficiently. Technicians arrive when promised, charge a straightforward rate for the time and skill involved, and keep working through tough diagnostics until the cooling or heating runs right again. They also manage ductless mini splits, boiler work, and related mechanical fixes that keep indoor air moving properly through Plano properties.

Customers note the crew gets jobs done quickly and correctly at a price that matches the effort, with clear updates along the way and solid results on tricky HVAC problems that had stumped others before. Reviews highlight reliable arrival times and fair billing for the experience brought to each site, though a few mention concerns over how some drive between calls. Overall the pattern shows steady performance on quality and communication that matches what Plano homeowners need when systems break down in the heat. DIRT Score 3.44 from 18 reviews on Finds.

“They completed their scope of work efficiently and in a very timely manner. They were offered overtime and they refused it and still completed the work ahead of schedule. I would be glad to use Alexander Mechanical again and I highly recommend them. This project was in a warehouse environment and made sure that when they left, their workspace was clean & orderly.”

“These guys show up on time, know what they are doing and charge a fair rate for their time and experience. Highly recommend for HVAC”

“Watched their technician grossly speeding and road raging other drivers, over 80 in a 45 mph zone, then forcing several other drivers off the road so he could pass unsafely. If they can't be respectful on the way to your house, what says they'll be respectful at your place?”

“Amazingly responsive, professional, knowledgeable. Alexander came through for us when no one else has been able to resolve any of our HVAC problems. The job is complicated but they forge ahead with successful results. Thank you Alexander!!”

“We were in a real pickle. The power company changed out our gas meter and in the process shook loose a bad joint in one of the gas lines under our house. They shut down our gas and told us we needed to get a licensed plumber out to fix it before they could restore our sevice. THIS WAS AT THE END OF JANUARY! No heat! I spoke with Mark on the phone, we pulled a permit with the city and he sent Byron and Kaleb out to get us fixed right away. Mark also came by the house to make sure everything was going smoothly and called after to make sure NV Energy got us turned back on. We're very happy. I will be calling them again to run gas to our backyard for the BBQ and firepit this Summer.”
