How It Works →Tucson Summer Survival Guide
Pro tips from the people who live the heat every day
Change your filter every 30 days
In Tucson dust, a dirty filter can raise your electric bill by 15% and make your system work twice as hard.
Set thermostat to 78° when away
Every degree lower costs you 5-8% more. Use a smart thermostat for automatic savings.
Check for leaks around windows & doors
Even tiny gaps let hot air in, which can raise your electric bill.
Schedule annual maintenance in spring
Beat the summer rush. Our Maintenance Club members never wait in line.
Keep vents clear of furniture
Blocked vents make your system work harder and unevenly cool your home.
Never ignore strange noises
A little rattle today can become a $3,000 repair tomorrow. Call us at the first sign.
