KJ's Cooling & Heating is a Phoenix HVAC contractor with a 4.1-star rating from 26 Google reviews, operating 24 hours a day, seven days a week. Owner Kris leads the company with technicians Robert, Trey, and Leonard on the team.

The positive reviews highlight competitive pricing as a consistent differentiator. One customer got four competing quotes for a full AC and furnace replacement — KJ's came in "MUCH less expensive" while still installing a new Rheem system with a gas-fired furnace in a single day. Kris also assisted the customer with their home insurance claim for the HVAC system. A property owner with four properties now uses KJ's as their go-to HVAC company after one no-questions-asked return visit during a Phoenix summer. A customer who has used KJ's for years specifically notes fair pricing and being educated on replacement options — given multiple price points — rather than being pushed to a single choice.

The review record also includes two substantive negative accounts. One describes a thermostat installation where the installer could not connect a system requiring a common wire, left the job incomplete, and ultimately refused to return — requiring a second company to resolve the issue. Another describes a missed appointment (technician went to the wrong address) and a conclusion that nothing was wrong despite the customer's AC running at 84 degrees inside; a different company later identified and fixed a connection issue.

For Phoenix homeowners comparing HVAC replacement costs, KJ's is worth getting a quote from alongside other contractors. For complex new installations, the review record suggests asking detailed questions about technician experience with the specific installation type. Call (602) 795-6754 for service or a free estimate.
