Frequently asked questions
Should I repair or replace my air conditioner?
As a rule of thumb, if your system is over 10–12 years old, needs a costly repair, or uses the old R-22 refrigerant, replacement usually makes more sense. We'll give you an honest assessment either way.
What size air conditioner do I need?
It depends on your home's square footage, insulation, windows, and layout — not just a quick guess. We measure your home's actual cooling load so you don't end up over- or under-sized.
Do you service heat pumps?
Yes — we install, repair, and maintain heat pumps of every major brand, including high-efficiency models that handle both heating and cooling.
