JMR Heating & Air Conditioning

JMR Heating & Air Conditioning is a family-owned HVAC contractor based in Laguna Niguel, California, holding a flawless 5.0-star rating from two verified client reviews. The company operates Monday through Friday from 7 AM to 5 PM and has built its reputation serving residents throughout South Orange County, including Aliso Viejo and surrounding communities. With a straightforward commitment to reliable heating and cooling solutions, JMR handles everything from new system installations to responsive repairs for homeowners who need dependable indoor comfort year-round.

What distinguishes JMR Heating & Air Conditioning is owner Mark's hands-on approach to every project. Rather than passing clients to a dispatcher, Mark personally walks each job with customers, provides verbal quotes followed by written proposals, and maintains direct communication throughout the process. Reviewers consistently note his flexibility with scheduling challenges and his willingness to accommodate urgent situations that other contractors brush off as impossible.

Mark and his crew demonstrated exceptional responsiveness when a commercial kitchen in the area faced a complete A/C collapse during an oppressive heat event, with interior temperatures reaching 111 degrees and staff unable to continue working. While competing companies quoted eight-week wait times, Mark expedited a new 3.5-ton rooftop unit and mobilized his crew for a 6 AM arrival, restoring the space to a comfortable 70 degrees the same morning at roughly half the price another vendor charged for emergency service. In a separate residential installation, buyer Joe Kellner, who describes himself as a demanding purchasing professional, awarded JMR top marks after the team completed a seamless one-day replacement, with his wife specifically commending the crew's courteous and tidy work ethic.
