October 2026: Just had another great experience with SWHC! Joe Kastens did our winter maintenance and diagnosed a wiring issue in our thermostat. Being a part of the maintenance plan family is well worth it. Thanks again! April 2026: Just had our Spring maintenance with Hayden Burnett. He was on time, professional, thorough and a true gentleman. Very thrilled with the service he provided. Hope to see him again next time. October 2025: We had Christian Meyers perform our semiannual routine maintenance on our air conditioner and furnace. Christian was on time, thorough and explained everything to us. A true professional and only what we've encountered since we started working with Southwest Heating and Cooling. Lisa and Cathy in the office can answer all your questions, help with installation dates, etc.... We just contracted with them to replace our water heater. While Christian was servicing our unit, he was able to provide an estimate for the replacement. Scheduling was made easy with a call to the office. Our new water heater will be installed in less than a week. June 2022 We had a new air conditioner and furnace installed. We had an immediate need. Mike, owner, met with us personally to review options from last year. Tony and Ray were terrific installers. On time, professional, left our place spotless. They went over all my questions. The office staff took care of all product registrations and rebate offers. This was a great outcome for us. Great job. July 2021 Great choice we made having Southwest Heating and Cooling service our unit. On time, spent time explaining to us what our system status is, etc.... Jake was great to work with. He left us with options on a new system, explained our options, reviewed their annual maintenance plan with us and overall treated us like family. We will definitely be recommending and using their services again.

Michael Carpenter was awesome and helpful. We were looking for additional air quality cleaner/improvements and he talked me through the options and let me do my homework and settle on the right one without pressure. Once we identified it, he was able to get back out the next week and install it. Really happy with Southwest Heating and Cooling.
