“Had an old unit which wasn’t working up to standards. Kept shutting off. The folks at One Hour Air came out gave me a very fair price and replaced the unit. From my first communication with with them to the installation everything went smooth and professional. I also used their duct cleaning which made the air inside my house free of contaminants. Great all around!”

“Best servicecompany in the area. We called them about 30 minutes before they show up at our door steps. Great education presentation by KC and Zo. I highly recommend them if you are looking to improve the indoor air quality, comfort and efficiency of your new or existing system. These guys takes time to educate you and your need.”

“I've had my share of bad experiences with previous HVAC vendors who are typically unprofessional, just looking for a sale, or untimely. However, One Hour Heating & Air Conditioning changed that for me. They are always on time, provide me with unbiased recommendations, and really show their care for customer relationships. I've used them for my all-home humidifier replacement, as well as duct cleaning and UV light system installation. Great value and professionalism, which is difficult to find these days. Za and Krunal especially are always a pleasure to interact with.”

“My HVAC system died at my yoga studio on a night it was below zero. it was well after 8 PM and I immediately went onto Thumbtack in a state of panic knowing i had early classes the next morning. KC from one hour responded immediately to my request and he was very helpful and reassuring. By the next morning he had a technician out to my studio and it was fixed by that afternoon. Rami the technician worked very fast and diligently. My unit is on the roof and he was up there in freezing temperatures! I highly recommend them for commercial HVAC situations! KC even came to my studio to explain exactly what parts were needed and helped me understand the pricing. you should definitely use them just be patient with their customer service people 🥴”
