About us

A family-owned team your neighbors trust

Harborview Heating & Cooling has served Bayport and the surrounding South Shore since 2009. We started as a two-truck operation and grew the honest way: by showing up on time, quoting fair prices, and treating every home like our own.

Reviews

What customers say

“Our AC died during the July heat wave and Harborview had a tech at the house within a few hours. He found a bad capacitor, replaced it on the spot, and the price was exactly what he quoted. Lifesavers.”
Danielle R. · Bayport, NY
“We replaced an ancient oil furnace with a high-efficiency system. The crew was clean, respectful, and walked me through everything. Our winter heating bills dropped noticeably.”
Mike T. · Sayville, NY
“I signed up for their maintenance plan two years ago and it has paid for itself. They catch little issues early and I never worry about the AC quitting in August.”
Karen P. · Blue Point, NY

Frequently asked questions

Do you offer emergency service?

Yes. We provide 24/7 emergency HVAC service across the South Shore. If your heat goes out on a cold night or your AC fails in a heat wave, call us any time and we will get a technician to you as fast as possible.

Do you offer financing on new systems?

We do. Flexible financing is available on qualifying furnace, boiler, and air conditioning installations, including low-monthly-payment plans, so a full system replacement does not have to be an all-at-once expense. We go over the options with your estimate.

Is a maintenance plan really worth it?

For most homeowners, yes. Two seasonal tune-ups catch worn parts and refrigerant issues before they turn into breakdowns, keep your system running efficiently, and satisfy the maintenance requirement on most manufacturer warranties. Plan members also get priority scheduling and discounted repairs.

What brands do you service?

Our technicians repair and maintain all major HVAC brands, including Carrier, Trane, Lennox, Rheem, Goodman, York, and Mitsubishi. We are not locked into one manufacturer, so we recommend the equipment that actually fits your home and budget.
