Questions & Answers

Heating & Cooling FAQs.

How often should I service my HVAC system?

Twice a year is ideal — a cooling tune-up in spring and a heating tune-up in fall. Regular maintenance keeps efficiency high, prevents breakdowns, and often protects your manufacturer warranty.

Do you install ductless mini-split systems?

Yes. Ductless mini-splits are perfect for additions, older Long Island homes, and rooms that are always too hot or too cold. We’ll size the system correctly and install it cleanly.

Do you repair all makes and models?

We service and repair all major brands of furnaces, boilers, heat pumps, and air conditioners throughout Suffolk and Nassau County.

My AC runs but the house isn’t cooling — what’s wrong?

It could be low refrigerant, a dirty coil, a failing capacitor, or a thermostat issue. We’ll diagnose the real cause and give you an honest repair-or-replace recommendation.
