FAQ
Common Heating & Cooling Questions
Should I repair or replace my system?
If your system is over 12 to 15 years old or needs frequent repairs, replacing it often saves money. We'll give you honest options.
Do you offer financing?
Yes. Approved homeowners can spread the cost of a new system with low monthly payments.
Are your technicians licensed?
Yes. Our technicians are licensed, insured, background checked and trained on all major brands.
Do you offer emergency repairs?
Yes. We offer same-day and after-hours repairs for no heat, no cooling and other urgent problems.
How often should I service my HVAC system?
Twice a year is ideal: your AC in spring and your furnace or heat pump in autumn. Regular tune-ups prevent most breakdowns.
