About KJ's Cooling & Heating
KJ's Cooling & Heating operates from Phoenix, Arizona, and holds a 4.1-star average across 26 client reviews. The company maintains 24-hour availability seven days per week, positioning itself as a resource for both scheduled maintenance and urgent breakdowns across the greater Phoenix metro area. Serving Gilbert, Chandler, and Mesa alongside Phoenix proper, KJ's Cooling & Heating has built its reputation through responsive emergency calls and transparent project quotes.
A distinguishing operational trait at KJ's Cooling & Heating is the round-the-clock scheduling policy. During Arizona summers when daytime temperatures routinely exceed 110 degrees, a failed cooling system constitutes a genuine safety concern. Reviewers describe swift response times and same-day arrivals, and one client notes a full equipment replacement completed within a single visit. The company also navigated home insurance paperwork for a client, smoothing an otherwise complex claims process. KJ's Cooling & Heating works with the Rheem brand, including the REEM series, and supplies multiple equipment tiers so homeowners can weigh upfront cost against long-term efficiency.
Darrin Francom called KJ's Cooling & Heating when his 17-year-old air conditioning system lost refrigerant and developed a coil leak. Technician Kris partnered with Robert to diagnose the problem and source an R-410 alternative compatible with the existing gas heater. Four competing firms submitted higher bids, and KJ's Cooling & Heating won the job. Robert and two additional technicians arrived with the new REEM unit, stripped the old system, and finished the installation before dark. Meanwhile, technician Trey addressed a heating malfunction for Laurynn Sillimon under a home warranty assignment, resolving the fault in a single afternoon without a callback.
Across four verified reviews, every client awarded five stars and each scenario involved a different specialist by name. Three reviewers specifically mention same-day or next-day arrival, and two clients note that KJ's Cooling & Heating undercut competing bids by a significant margin. One reviewer with four rental properties now routes all service calls through this company, and a second client with a home warranty chose KJ's Cooling & Heating over the warranty-assigned default. Negative feedback does not appear in the current review set.
What Customers Say
6 of 8 reviewed customers gave 4-5 stars. Owner Kris is praised for pricing well below competitors on a full HVAC replacement, assistance with insurance claims, and same-day availability. A multi-property owner uses KJ's exclusively after a reliable same-day return visit. Two negative accounts are worth noting: one describes an incomplete thermostat installation that required a second company; another describes a missed appointment, diagnosis of "nothing wrong," and a resolution by a different company that found an actual connection issue.
