1
How do I know if my HVAC system should be replaced?

Replacement may make sense when the system is older, unreliable, inefficient, unsafe, or facing a repair that costs too much compared with the remaining life of the equipment.

2
Do you recommend repair before replacement?

When repair is practical and responsible, Greenwich HVAC will say so. If replacement is the better long-term choice, the reasons should be explained clearly.

3
What matters most when replacing HVAC equipment?

Sizing, ductwork or hydronic layout, airflow, controls, comfort complaints, installation quality, and future service access all matter. The equipment brand is only one part of the decision.

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.
