"My experience with heating and air conditioning repair, replacement, and new installation was excellent. Their staff was amiable, well-informed, and meticulous. Our device is operating more efficiently than before. Really trustworthy service!"

It took 5 days  and went very well.  Jesus and Juan were hard workers and nice to have around. 

When Duke initially evaluated the house, he pointed out some reasons the old furnace system was inadequate and corrected these problems so the house now heats quietly and evenly, which is a nice change.  2 of the air returns were redone and an additional one added to improve circulation. The associated ducts in the attic were upsized which also helped. All the old crawl space duct work was replaced with a modern version and the associated register covers replaced..

"The team at Smart Heating & Air Conditioning are second to none. Quality work and amazing customer service. Would recommend everyone to them for your heating and A/C needs!"

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"Excellent. Max arrived on time and got straight to work. He inspected the furnace, took measurements of the air temp and cleaned all the filters. He provided some helpful information for the potential future replacement of the furnace with options and estimates. Max was professional and personable. The total cost was as quoted. Other companies I contacted either would not give me a quote over the phone, charged to just dispatch a technician, or quoted more than double."

"Air Sharks are very professional and I think they did a good job on installing HP HVAC in our property."

"They came out quickly. Did the job properly replace the heating and air-conditioning unit very happy with their work and the price I would recommend them to anyone."

"The repair person showed up on time, quickly diagnosed the problem, had a replacement part on hand, quickly repaired the wall furnace, cleaned up the dust/debris, and did a CO2 check."

"I found Jim's Air Systems through HomeAdvisor, and Josh was the first contractor to reach out to me personally, not through an automated service. From the start, communication with him was excellent. I provided him with a detailed description of the job, along with model numbers and photos of my existing system. He reviewed everything carefully rather than giving me a quick, generic quote. I received another bid for comparison, but the other contractor was significantly more expensive and wanted to upsell me. It was refreshing that Josh understood I had done my research, knew what I wanted, and didn't pressure me into unnecessary upgrades. Josh's team arrived on time, completed the work as scheduled, obtained the required permit, and left my home as clean as they found it. Overall, a great experience and a solid value. I wouldn't hesitate to recommend them."
