Quantum Heating and Cooling

Quantum Heating and Cooling has earned a perfect 5.0-star rating across 92 reviews while serving homeowners and businesses throughout Lehi and the broader Utah County area. This contractor handles everything from routine maintenance to full system replacements across both residential and commercial properties. Their broad service menu covers air conditioning, heating, ventilation, and niche offerings like fireplace services, chimney repairs, and refrigeration work.

A detail that surfaces repeatedly across customer reviews is the free diagnostic offer and the willingness to answer calls outside normal business hours, including one reviewer who reached them at 9 pm and received a same-day callback. The company also distinguishes itself with specialty trades not commonly found under one HVAC roof, including fireplace service, chimney cleaning and repairs, and boiler work. These capabilities allow homeowners to consolidate vendors rather than managing separate contractors for different systems.

Joshua stands out by name in multiple reviews for his diagnostic skill and willingness to address secondary concerns during a single visit. ShayLea called Quantum about a malfunctioning gas fireplace, and Joshua identified both the fireplace issue and a separate AC problem during that same appointment. Because the AC unit was over 20 years old, replacement made more sense than repair, and the crew returned three days later with a crane to lift the old rooftop unit off the building before installing the new system. Al Michelle experienced a furnace breakdown on a weekend and had Joshua on-site the next day, where Joshua explained the repair process in detail and stayed until the heat was running again.
