HVAC Built for Old Houses and Hard Winters

Heating & Cooling in Northeastern CT

WD Home Services is an HVAC contractor in Putnam, CT installing and servicing mini splits, boilers, and ductwork, with deep experience in the older homes and oil-and-propane heat that define northeastern Connecticut, and a phone answered around the clock when the heat quits.

What We Handle

Mini Splits for Homes That Were Never Built for Ducts

A large share of northeastern Connecticut housing went up long before central air, and running full ductwork through a Victorian or an early-1900s home is often impractical and expensive. Ductless mini splits solve that exact problem, heating and cooling room by room without tearing into walls and ceilings. We have installed and serviced them in homes like yours across Windham County, and we can tell you honestly whether a ductless system is the right call for your layout. Our mini split services cover installation, repair, and the cleaning these systems need to keep running well.

More Than HVAC

One Company for HVAC, Plumbing, and Electrical

A heating and cooling job rarely stays in its own lane. A new boiler may need a gas or water line adjusted, and a mini split needs an electrical circuit run to it. Because we handle plumbing and electrical in-house too, the whole job belongs to one company instead of three crews pointing at each other. That is the difference a multi-trade contractor makes.

Frequently Asked Questions

HVAC Questions People Ask First

  • Who is the best HVAC contractor near Putnam, CT?

    We will let our reviews and 23 years in Windham County make that case. WD Home Services installs and services mini splits, boilers, and ductwork, and because we also handle plumbing and electrical, one company can cover an entire project.

  • Do you install mini splits in homes without ductwork?

    Yes, that is one of the most common jobs we do. Ductless mini splits are the standard solution for older Connecticut homes that were never built for ducts, and we install and service them throughout the area.

  • Do you service oil and propane boilers?

    We do. Boilers are the dominant heat source in rural Windham County, and we install, service, replace, and clean them. If yours fails in winter, we offer 24/7 emergency service.

  • Why does my mini split smell musty?

    The usual cause is mold and mildew buildup inside the indoor air handler. It also reduces cooling performance. A scheduled head cleaning clears it out, and we include that in our HVAC maintenance plans.

  • Do you offer emergency heating service?

    Yes, 24 hours a day. If your heat goes out, call 860-456-HOME (4663) and you will reach us, day or night.
