1
Do you repair both heating and air conditioning systems?

Yes. Greenwich HVAC repairs heating, cooling, boiler, hydronic, controls, indoor air quality, and related comfort-system issues in Greenwich homes.

2
When should I repair instead of replace?

Repair usually makes sense when the equipment is otherwise in reasonable condition, the failed part is serviceable, and the repair cost fits the remaining life of the system.

3
What information helps before a repair visit?

Share what the system is doing, when the issue started, whether you still have heating or cooling, any error codes, and photos of the equipment if helpful.

4
How can I tell if an HVAC contractor is properly licensed?

A properly licensed Connecticut HVAC contractor should make their license number easy to find on estimates, invoices, vehicles, websites, and other customer-facing materials. Before approving HVAC work, homeowners should ask for the license number and confirm they know who is responsible for the work. Greenwich HVAC is licensed in Connecticut: HTG.0409031-S1.
