FAQ

Frequently Asked Questions

Answers Long Island homeowners ask us most about cooling.

1What cooling services do you offer on Long Island?

We repair, maintain, and install central air conditioning, ductless mini-splits, and heat pumps, set up thermostats, and install standby generators across Suffolk and Nassau County.

2How often should I service my air conditioner?

Once a year, ideally in spring before the cooling season. An annual tune-up keeps your AC efficient, lowers bills, and helps prevent summer breakdowns.

3Do you install ductless mini-split systems?

Yes. Ductless mini-splits are ideal for additions, older homes, and rooms your central system cannot reach, and we install all major brands.

4What AC and heat pump brands do you carry?

We install and service Durastar, Fujitsu, Rheem, Trane, Ruud, Goodman, Samsung, GE, Mitsubishi, LG, Lennox, and Panasonic, among others.

5Should I repair or replace my air conditioner?

If your system is relatively young and the repair is minor, repair makes sense. If it is older or inefficient, a high-efficiency replacement usually pays off. We give honest advice and free estimates.

6Do you offer financing on new cooling systems?

Yes. We offer financing through Wisetack so you can spread the cost of a new AC or heat pump into low monthly payments.
