MC Electric Comfort Systems is a veteran-founded, fully licensed electrical and HVAC contractor serving Derry and the surrounding Rockingham County communities. As one of southern New Hampshire’s largest towns — home to roughly 34,000 residents — Derry’s housing runs the full range, from pre-1940 New England colonials to mid-century homes and newer developments off I-93. With a median home built around 1981 and more than one in ten homes dating before the 1940s, many Derry houses are running electrical systems that were never designed for today’s demand. That is exactly where we come in.

Electrical Services in Derry

Derry’s older housing stock makes electrical panel and service upgrades some of our most-requested jobs — homes built decades ago simply weren’t wired for modern EV chargers, heat pumps, and home offices. We handle:

• Electrical panel & service upgrades
• Rewiring and outdated / knob-and-tube replacement
• EV charger installation
• Standby generator installation — essential for New Hampshire’s winter storm outages
• Lighting, outlets, and code-compliant repairs
• Residential & commercial electrical work

HVAC Services in Derry

Derry’s four-season climate — long, cold, snowy winters and warm, humid summers — makes a high-efficiency heat pump one of the smartest investments a homeowner can make: a single system that heats through a New Hampshire winter and cools through a humid July, often far cheaper to run than oil or electric baseboard. We install and service:

• Heat pump & ductless mini-split installation
• Central AC installation & repair
• Heating installation & repair
• Mini-split cleaning & maintenance
• Ductwork services

Yes — we’re licensed for both, so one company handles your panel upgrade, EV charger, heat pump install, and AC repair.

My Derry home is older — can you upgrade my electrical panel?

Absolutely. Many Derry homes predate modern electrical demand; we upgrade panels and service to safely support EV chargers, heat pumps, and additions.

Yes. Today’s cold-climate heat pumps and mini-splits are built for New Hampshire winters and heat efficiently well below freezing — while cooling through humid summers.
