HVAC Services in Greenwich, CT
Heating and cooling help in Greenwich, CT, from system repair and seasonal maintenance to ductless mini-splits, duct and vent work, and thermostat installation, all handled by licensed HVAC technicians.
HOW WE WORK
Our HVAC Service Process
Every heating and cooling visit follows the same four steps, so you always know what happens next.
Step 1
System Inspection
We ask what you’ve noticed, then check airflow, temperatures, electrical components, and controls at the equipment itself to trace the problem to its source instead of guessing from the symptom.
Step 2
Plain-Language Options
You hear what we found and what each option involves, whether that’s a simple part swap, a cleaning, or a bigger repair, and no work starts until you approve it.
Step 3
Careful Repair Work
A licensed HVAC technician completes the work, whether that means replacing a failed capacitor, resealing a leaky duct joint, or mounting and wiring a new smart thermostat.
Step 4
Final Checks And Follow-Up
Before we leave, we run the system through a complete cycle and show you what changed. If questions come up later, a phone call reaches us.

OUR SERVICES
About Our Greenwich HVAC Services
A furnace that quits in January and an AC that leaks water in July share one trait: neither waits for a convenient moment. The services below cover the heating and cooling Greenwich homes depend on, so a single call gets help for the whole system.
HVAC Repair & Maintenance
Weak airflow, a system that runs nonstop, or a furnace that clicks without lighting are all reasons to schedule HVAC repair in Greenwich instead of nudging the thermostat again. We trace faults in blowers, igniters, capacitors, and control boards, and we offer seasonal maintenance that cleans, adjusts, and checks your equipment before summer heat or winter cold puts it to work.
Ductless Heating & A/C
Many older Greenwich colonials and Victorians were built without ductwork, which makes a ductless mini-split a practical way to heat and cool an addition, sunroom, or finished attic. We install, maintain, and repair ductless heat pumps, from cleaning indoor head filters to fixing drainage and refrigerant problems.
Duct & Vent Cleaning
Dust puffing out of registers, a film of grit on furniture soon after you clean, or a home that just went through a renovation can all point to dirty ductwork. Duct cleaning removes built-up dust, pollen, and debris from supply and return lines, and we check vents and grilles for blockages while we’re there.
Duct & Vent Installation & Repair
Rooms that never get comfortable, ducts that rattle or whistle, or a basement that feels warmer than the floors above can mean leaking joints, crushed runs, or poorly sized vents. We repair damaged ductwork, seal loose connections, and install new duct runs and vents for renovations, additions, and system upgrades.
Thermostat Installation & Repair
A blank screen, a system that ignores new settings, or rooms that never match the display often trace back to the thermostat or its wiring. We handle thermostat installation and repair, including smart and programmable models matched to your equipment.
Central AC, Heating & Emergency HVAC
Central air conditioners, furnaces, and boilers each get a closer look on their own pages: AC repair, air conditioning installation, and heating repair and installation. If the house has no heat or cooling right now, see our emergency HVAC page.
WHY CALL US
Why Greenwich Homeowners Call Us
When you call us, a licensed HVAC technician looks at the whole system rather than just the part that failed. That approach carries through every furnace, boiler, air conditioner, mini-split, duct run, and thermostat we service in Greenwich.
We explain what we find in plain terms and answer your questions before anything gets started, so you’re never left guessing about your own equipment. When heat or cooling stops completely, our 24/7 emergency HVAC service is available day or night.
Our aim is equipment that runs quietly and evenly through humid summers off Long Island Sound and cold Connecticut winters. Along with Greenwich itself, we serve nearby Cos Cob, Riverside, Old Greenwich, Byram, Glenville, and Stamford.
