Do I need to keep my furnace or boiler as backup?

Not necessarily. Many Lexington homes run a heat pump as the primary heat source year-round, while others prefer a dual-fuel setup that keeps an existing furnace or boiler for the coldest stretches of winter. We size the system based on your home and your comfort preference.

How many indoor units would my Lexington home need?

It depends on the layout. A single problem room might need one indoor unit, while a whole-home conversion in a larger Lexington colonial could call for four or more zones. We measure the home before recommending a count.

Will my electrical panel need an upgrade?

Sometimes. Larger ducted heat pump systems draw more power than a single mini-split, so we check your electrical panel capacity with every quote and flag any needed upgrades before installation day.

Do you repair and maintain existing heat pumps in Middlesex County?

Yes. We service heat pumps we didn't originally install throughout Middlesex County, including filter and coil cleaning, refrigerant checks, and troubleshooting for underperforming units.

How do heat pump running costs compare with oil in Lexington?

Running costs depend on your electric rate, the age of the heat pump, and how well the home is insulated, but many Lexington homeowners see lower seasonal costs than an aging oil system, especially with a newer, properly sized heat pump.

Is ice on the outdoor unit normal during a Lexington winter?

A light layer of frost that defrosts on its own is normal operation. Heavy ice buildup that doesn't clear, or a unit that stops running, usually points to a refrigerant or defrost cycle issue that warrants a service call. Ask about current heat pump rebates Lexington, MA offers whenever you schedule that visit, since qualifying repairs and upgrades sometimes overlap with Mass Save incentives.

How long does a multi-zone ductless installation take?

Most multi-zone ductless installations in Lexington homes take one to three days depending on the number of indoor units, line set routing, and any electrical work required.

Ductless and Ducted Heat Pumps Across Lexington

A heat pump in Lexington, MA can mean two very different projects: a ductless mini-split for one or two problem rooms, or a fully ducted heat pump replacing a furnace or air handler across the whole house. We install and service both, and we walk you through the real tradeoffs before you commit.

Single-zone and multi-zone ductless layouts

A single indoor unit solves one stubborn room; a multi-zone mini-split installation in Lexington can cover an entire addition, finished basement, or upper floor with individually controlled heads.

Whole-home vs partial-home conversions

Some homes are ready for a full ducted heat pump Lexington conversion right away, while others do better starting with the rooms that struggle most and expanding later. We size each option honestly rather than upselling the bigger job by default.

Dual-fuel setups that keep an existing furnace

If you would rather keep an existing furnace or boiler for the coldest days, we can set up a dual-fuel system where the heat pump handles most of the season, and the furnace covers the extremes.
