Frequently Asked Questions

How often should I have my HVAC system serviced?

We recommend seasonal maintenance—once before summer cooling season and once before winter heating season. This keeps your system efficient and helps catch problems early before they become expensive repairs.

What's the average lifespan of an HVAC system?

Most systems last 15-20 years with proper maintenance. If your system is approaching this age or requiring frequent repairs, it might be time to discuss replacement options with our team.

Can a programmable thermostat really save me money?

Yes. A programmable or smart thermostat can reduce your energy usage by automatically adjusting temperatures when you're away or sleeping, potentially saving you hundreds per year.

Why is my energy bill so high?

Several factors could be responsible—poor insulation, a declining HVAC system, dirty filters, or incorrect thermostat settings. We can diagnose the issue and recommend solutions during a home energy evaluation.

Do you offer maintenance plans?

Absolutely. Our maintenance plans provide regular system check-ups, priority service, and discounts on repairs. They're an affordable way to extend your system's life and prevent emergency breakdowns.
