"Albert was very polite, helpful and showed me some easier ways to maintain my system. He also offered suggestions on how to best utilize the 2 systems we have to best advantage. I was notified when he would arrive (along with a photo), then an update (as he was early), and work was completed in a timely, efficient manner. I would definitely use Southland Heating again!"

"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"We had hired Air-Tech in 2019 for a whole-house, ductless system. That system still works flawlessly, and we needed another unit for a permitted garage conversion/ADU. We were also in a time-crunch, as our final inspection is coming up, and heating/ac is needed for approval. Though due to the high season, we were quoted about 4 weeks, it took "about 3 days"! We were surprised to hear that they would make a special trip to install our unit. Same, familiar faces as the original system, and same GREAT and personable service (most polite techs in ANY industry, and we know, as we have done lots to our house over the last 7 years). 5 hours later and we had ice-cold air blowing in our new addition, very tidy installation inside and out, and we are all set for final approval by the building inspector AND years of enjoyment. We added the service contract, so these pros can keep our whole house system including the addition, in tip-top shape, under warranty and lasting for years to come. GREAT Job and THANKS A MILLION, AIR-TECH!"

"I am thoroughly impressed with the exceptional service I received from HD Mechanical! Their team recently installed mini splits in my home, and the entire experience was seamless and professional. From the initial consultation to the final installation, their expertise and attention to detail were evident. The installers were courteous, informative, efficient, and ensured a precise installation. The mini splits are now providing comfortable and quiet heating and cooling, exceeding my expectations. I highly recommend them for their accuracy, professionalism, and top-notch service. Five stars and a job well done!"

"Mr Avery was extremely professional and very informative. He explained the price, which I felt was reasonable and fair. He explained the warranty process. Also informed me on how getting annual maintenance on hvac system extends life expectancy. Will have him out during the winter for a heating inspection"

"He was thorough, knowledgeful, listened to my concerns, respectful and got the job done quickly and efficiently with my plumbing problem. I would recommend Alpine Heating, plumbing and electrical services to anyone...and do recommend them."

"QNZ was able to upgrade the existing central A/C unit to the original house as well as tie-in the ducts to a flat roof addition. This a particularly challenging task, but they were able to make it happen. Now we can all be cool in the summer and warm in the winter. "
