FAQ

HVAC Questions, Answered

How do I know if I should repair or replace my HVAC system?

If your system is over 10–15 years old, needs frequent repairs, or your energy bills keep climbing, replacement may make more sense. We’ll give you an honest assessment and lay out the costs both ways — no pressure either direction.

We recommend a tune-up twice a year — once for your cooling system in the spring and once for your heating system in the fall. Regular maintenance keeps everything running efficiently and catches small issues early.

It depends on your home’s square footage, insulation, windows, and layout. A system that’s too big or too small won’t run efficiently. We do a proper load calculation to recommend the right size for your space.

A well-maintained furnace can last 15–20 years and a central AC unit about 12–15 years. Regular maintenance is the biggest factor in getting the full life out of your equipment.

We prioritize no-heat and no-AC calls and offer same-day service whenever possible. Call us and we’ll get a technician to you as fast as we can.

Yes. We offer flexible financing options to help spread the cost of a new system into manageable monthly payments. Ask us for details when you call.

We’re a GE Authorized HVAC Pro, and we install and service all major brands. We’ll recommend the best equipment for your home and budget — not just the most expensive option.
