WHO WE ARE

Licensed HVAC technicians for Greenwich homes of every age

Pro HVAC Greenwich CT sends licensed HVAC technicians to homes across Greenwich, CT to repair, maintain, and install the heating and cooling equipment that keeps each room comfortable.

Greenwich houses vary widely, from Victorians heated by hot-water boilers and radiators to newer homes with central air and multiple zones. We look at how your house is built and how you use it, then recommend the repairs, upgrades, or maintenance that fit.

Our goal is straightforward: keep your system running safely, explain what we find in plain language before we pick up a tool, and leave your home as tidy as we found it. Careful workmanship and clear communication guide every visit, from a tune-up to a full replacement.

HOW WE WORK

Why Do Greenwich Homeowners Call Us?

When your heat stops on a January night or your AC quits in a humid July heat wave, you want a licensed HVAC technician who listens first. We diagnose the actual cause, explain your options clearly, and only then start the work.

Every visit gets the same care, whether we are replacing a worn blower motor, clearing a clogged condensate line, or installing a ductless mini-split in a finished attic. We protect your floors, clean up when we finish, and stay available 24/7 when an HVAC emergency cannot wait.

COMMON QUESTIONS

Your HVAC Questions, Answered

Here are straightforward answers to the heating and cooling questions Greenwich homeowners ask most, from maintenance timing and system sizing to ductless options and emergencies.

Plan on two visits a year: a cooling check each spring before the humid months, and a heating check each fall before the first cold snap in Greenwich.

Sizing depends on square footage, insulation, windows, and how much sun each room gets. A proper load calculation avoids an oversized unit that short-cycles or an undersized one that never keeps up.

A tune-up catches worn belts, weak capacitors, dirty coils, and clogged filters before they cause a breakdown, and a clean, well-adjusted system uses less energy to keep you comfortable.

Replace filters on schedule, seal leaky ducts, clear leaves and snow from outdoor units, and let a smart thermostat ease off when nobody is home.

Watch for repairs that keep coming back, rooms that never reach the set temperature, rising energy bills, and loud or unusual noises. Many central air conditioners last roughly 15 years, and shoreline salt air can wear outdoor coils sooner. Older systems that use R-22 refrigerant are also harder to service. A licensed HVAC technician can help you weigh repair against replacement.

Yes. Our emergency HVAC service runs 24/7, nights, weekends, and holidays included, for a boiler or furnace that quits in freezing weather or an AC that fails during a heat wave.
