Family-Owned Heating & Cooling Company with Owner-Managed Emergency Dispatch
Autumn Air Heating & Cooling was built on something personal. Owner Joshua Nepa named the business after his daughter, Autumn, and his family’s hands-on involvement shaped what the company became. Joshua has worked in the HVAC industry since 1994 and earned two consecutive nominations as a top HVAC technician before bringing that experience to Arizona. Today, Autumn Air Heating & Cooling serves tens of thousands of customers across the greater Phoenix area.
San Tan Valley sits squarely in the Sonoran Desert, where summer temperatures push well past 100°, and monsoon season brings its own demands. Your HVAC system works harder here than almost anywhere in the country. San Tan Valley homeowners can reach our certified, experienced HVAC team any time.
Call (602) 905-6468 for same-day service or emergency dispatch.
Why San Tan Valley Homeowners Call Autumn Air Heating & Cooling
We get called out at all hours. A customer reached us after 9:30 pm and had a technician at the door in under an hour. That kind of response isn’t an accident. Owner Joshua Nepa personally manages chat support and coordinates after-hours emergency dispatch, which means when you reach out on a summer night, you’re connecting with someone who’s accountable for the outcome. Multiple customer reviews have documented this involvement by name.
Our technicians hold NATE credentials, BPI certification, Master Heat Pump certification, and qualification status with both Arizona Public Service (APS) and Salt River Project (SRP). That status means qualifying installations may allow customers to access potential utility rebates through APS and SRP programs. We carry a 4.9-star rating across more than 1,510 customer reviews, and reviewers consistently note that technicians arrive earlier than the quoted window.

HVAC Services We Offer in San Tan Valley
We cover the full range of residential heating and cooling needs. Whether your AC system needs a same-day repair or you’re replacing a unit that’s reached the end of its life, our technicians arrive equipped to diagnose and get to work.
Our installation and service work spans:
- AC repair and replacement
- Heating repair and installation
- Heat pump service
- Ductless mini split installation
- Smart thermostat installation
- Duct cleaning
- Indoor air quality solutions
- Preventive maintenance
For homes without existing ductwork, or rooms that never quite reach the right temperature, ductless mini split systems provide zoned control without the need for a full duct system. Heat pumps are another efficient option for Arizona homeowners: a single system handles both heating and cooling, which fits the region’s mild winters and extreme summers well. Every technician who steps onto your property understands what high-demand desert operation does to equipment over time.
Preventive Maintenance & Our Maintenance Agreement
A tune-up from Autumn Air Heating & Cooling is performed by NATE-certified technicians working to factory specifications. During each visit, we clean the air handler, replace air filters, check refrigerant levels, inspect ductwork for leaks, calibrate the thermostat, and verify safety controls. This isn’t a checkbox inspection. It’s the kind of thorough service that can help catch a failing component before it becomes a 105° emergency.
For homeowners who want long-term protection, our Preventative Maintenance Agreement pairs annual tune-ups with savings on repairs. Standard manufacturer warranties typically cover parts only. Labor costs, service call fees, and part acquisition costs generally stay with the homeowner. The agreement helps reduce those costs: for a one-time payment starting at $479 for a 1-unit, 2-year plan (or from $18.99 per month with the Autumn-Matic Agreement), members get no service call fees, 20% off parts and labor on repairs not covered by warranty, and a lifetime warranty on most parts (see terms).
Members also get an annual summer AC tune-up and winter heat check, with emergency service available within 24 hours. During peak summer demand in San Tan Valley, when wait times for non-members can stretch into days, members go to the front of the line. Customers who aren’t on a plan still receive a 1-year warranty on parts.
Indoor Air Quality in San Tan Valley
Desert living means ongoing exposure to fine dust and particulates that accumulate in ductwork and move through your home with every cycle your system runs. Monsoon season compounds this: the summer storm season introduces additional humidity and airborne debris that can affect both HVAC performance and indoor air quality. Our duct cleaning service removes what’s built up in the ventilation system, and we also offer air filtration upgrades and other indoor air quality solutions for homeowners dealing with dust, allergens, or contaminants circulating through the system.
