EXCELLENT Based on 1005 reviews Posted on Google Yonat ShimronTrustindex verifies that the original source of the review is Google. My furnace couldn't keep up on one of the coldest nights of the year. An Alternative Aire technician was able to come to the house on Sunday morning to fix the problem. I so appreciate their quick and knowledgeable repair crew.Posted on Google Angela TempleTrustindex verifies that the original source of the review is Google. Joey K. visited our location and completed a thorough heating tune-up on our heat pump. He was friendly and professional and took the time to explain everything. The communication from scheduling to the completion of the job was fantastic.Posted on Google Alison BTrustindex verifies that the original source of the review is Google. Joey saved the day when came to fix my system after I’d been without heat for 3 days during this terrible wintry weather. He was polite, personable, and diagnosed and fixed the problem quickly. SO glad to be warm again!!Posted on Google Brian DoraisTrustindex verifies that the original source of the review is Google. Had an issue with my heat pump during a recent cold snap. It was Sunday night so I went to their website and booked an appointment for 8:30-11:30am Monday. Joe messaged and showed up at 7:30am! Took Joe no time at all to figure out my issue and he had me sorted out. He took time to explain my situation and had me check in with him on his personal phone later in the day to ensure all was good. Very impressed with the level of service and the reasonable pricing. Thanks for keeping us warm!Posted on Google David CriswellTrustindex verifies that the original source of the review is Google. Super fast furnace repair on the coldest morning of the year. Long time customer. Recommend the maintenance plan.Posted on Google JamesTrustindex verifies that the original source of the review is Google. Our heat system stopped working as freezing temps were going to hit this weekend. I called earlier this morning and Charles Stewart arrived later at 4PM. Turns out a motor was out so he quickly called a nearby supplier to leave a new motor for him before they closed at 5PM!! He came back with the motor and within minutes was able to get the heat was back on. MUCH THANKS to Charles Stewart and Alternative Aire!!
