Questions
Do I need AC maintenance before summer?
While AC maintenance requires 60°F+ temperatures, we recommend scheduling during off-peak seasons to avoid spring rush. Annual tune-ups ensure optimal performance regardless of timing.
Why won't my AC cool to the set temperature?
AC systems typically cool 18-20°F below outdoor temperatures. If performance falls short, check insulation or schedule a professional inspection for potential issues.
What payment methods do you accept?
We accept major credit cards, cash, and checks. Flexible financing options, including 0% interest plans, are available for qualified customers.
Which HVAC brands do you service?
We install and service Lennox, Mitsubishi, Carrier, Generac, and Bradford White systems, while maintaining expertise across most other brands in the industry.
Can you troubleshoot HVAC issues over the phone?
Accurate diagnosis requires in-person evaluation. Our technicians use specialized tools to test equipment and identify root causes during on-site visits.
How often should HVAC filters be replaced?
Replace filters every 30-60 days, or more frequently in homes with pets or allergies. We offer convenient filter delivery and installation services.
