HVAC Questions and Answers for Greenwich, CT

Clear answers to the questions Greenwich, CT homeowners ask us about air conditioning, heating, ductless systems, ductwork, thermostats, and emergency HVAC service.

What happens during an HVAC service visit?

A licensed technician inspects your equipment, tests how it is running, and explains what is wrong and what can be done before starting any repair.

Are your HVAC technicians licensed?

Yes. A licensed HVAC technician handles the work in your home, from diagnosing a failed blower to setting up a new ductless system.

Do you offer emergency HVAC service?

Yes. We provide 24/7 emergency HVAC service across Greenwich and nearby Connecticut towns for problems that cannot wait until morning, like a boiler that quits during a cold snap or a system that keeps shutting off.

What HVAC services do you offer?

We cover the full range of home comfort work, including AC repair and maintenance, air conditioning installation, furnace and boiler repair and installation, ductless mini-split systems, duct and vent cleaning and repair, and thermostat installation and other HVAC services.

How often should I change my HVAC air filter?

Check it monthly and replace a standard one-inch filter every one to three months, sooner during spring pollen season.

What areas do you serve?

We serve all of Greenwich, CT, including Cos Cob, Riverside, Old Greenwich, Byram, and Glenville, plus Stamford and other Connecticut towns within about 15 miles of Greenwich. We work in Connecticut only. Not sure about your address? Call (475) 410-8119.

Is a ductless mini-split a good fit for my home?

Often, yes. Ductless mini-splits suit older Greenwich homes heated by boilers and radiators, where there is no ductwork for central air, as well as sunrooms, additions, and finished attics.

How do I schedule a visit?

Call (475) 410-8119 any time, or send a request through our online contact form with a short description of the problem, and we will reply to set up a visit.

How do I know if my ducts need cleaning?

Common clues include dust that settles soon after cleaning, a musty smell when the system starts, visible debris around supply vents, and rooms that get weak airflow. A licensed technician can look inside the ductwork and tell you whether cleaning or repair is needed.

Why is my AC running but not cooling the house?

The usual causes are a clogged filter, a dirty outdoor coil, a frozen indoor coil, low refrigerant, or a failed capacitor that stops the outdoor fan or compressor. Replace the filter and clear leaves and grass away from the outdoor unit. If the house still will not cool, book AC repair in Greenwich.

Is it worth upgrading to a smart thermostat?

For many households, yes. A smart or programmable thermostat can lower the temperature while you sleep or are away and bring it back before you return, which cuts wasted run hours. Some older boiler controls need an added wire or adapter first. We handle thermostat installation and repair for most heating and cooling setups.

What should I do if my heat goes out in winter?

Check that the thermostat is set to heat with fresh batteries, the furnace or boiler switch is on, and the breaker has not tripped. If you smell gas, leave the house and call your gas utility from outside. Otherwise, call (475) 410-8119 for 24/7 emergency HVAC service.
