How It Works →Tucson Fall Comfort Guide
Simple ways to get your home ready for cool desert nights
Test your heat early
Turn the heat on during a mild afternoon so you find any problem before the first cold night, not during it.
Know the first-run smell
A faint dusty smell the first time your heat runs is normal, but if it lingers or smells electrical, shut it off and give us a call.
Start the season with a fresh filter
Monsoon dust clogs filters fast, so a clean one helps your system heat evenly and breathe easy.
Book your fall tune-up
A heating check before winter catches worn parts early, while the schedule still has room.
Test your carbon monoxide detectors
If you heat with gas, press the test button on every CO detector and swap in fresh batteries now.
Clear around the outdoor unit
If you have a heat pump, pull leaves, weeds, and desert dust away from it so it can work all winter.
What Tucson Customers Say
“We called them bright and early after our AC went out and they were at our house within a couple hours. They quickly diagnosed the problem and explained our options. We are very happy with the work that they did and appreciate their kindness.”
“AC went out evening before family event. Called Serrano and they were at my home within 2 hours and got unit working well again. Great service!”
“Avery and Micah provided 5-star service. During my annual A/C inspection it was discovered I needed to replace a part. They went and got the part and made a second trip to my house same day to replace. Excellent experience. Company is very reliable and professional.”
