Certified Mitsubishi Electric Ductless & Heat Pump Solutions Across CT
5-Star Rated. Same-Day Service. Certified Mitsubishi Diamond Dealer.
Norwalk is one of the most distinctive HVAC markets on the Connecticut shoreline. You have historic neighborhoods like East Norwalk and Rowayton with homes built in the early 1900s — many of them without traditional ductwork. You have the South Norwalk waterfront where older mixed-use buildings have been converted to residential. And you have newer construction throughout Wolfpit, Cranbury, and the Route 1 corridor.
What all of these homes share: Fairfield County’s coastal humidity and heat load. Express Home Services provides HVAC repair, installation, and maintenance throughout Norwalk. We are family-owned, certified by Mitsubishi Electric as a Diamond Dealer, and have earned a 5.0-star rating from homeowners across Connecticut.
Norwalk summers run hot and sticky. The combination of coastal heat and Long Island Sound humidity creates conditions that stress HVAC systems harder than inland markets. We handle all central air conditioning repairs for Norwalk homeowners: AC not cooling, refrigerant issues, capacitor and electrical failures, coastal corrosion and outdoor unit maintenance, frozen evaporator coils, blower motor and airflow issues, and emergency AC repair.
Salt air accelerates corrosion on outdoor condenser coils and electrical components — Norwalk homes near the water benefit from annual preventive maintenance more than inland properties.

Ductless mini splits are the right solution for a large portion of Norwalk’s housing stock. Norwalk has a significant number of homes built before central air conditioning was standard — Victorian and craftsman-style homes in East Norwalk and Rowayton, older cape cods throughout South Norwalk, and converted industrial and commercial spaces in the SoNo district. As a certified Mitsubishi Electric Diamond Dealer, Express Home Services installs and services Mitsubishi ductless systems throughout Norwalk.
For Norwalk homes with existing ductwork in serviceable condition, central air conditioning remains the most cost-effective whole-house cooling solution. We do not size by square footage alone — we calculate first, then specify equipment. Financing available — $0 down for qualified applicants.

Fairfield County winters are milder than Hartford County on average, but Norwalk still gets extended cold periods. We service and install furnaces, boilers, and heat pumps for Norwalk homeowners. Norwalk has a higher-than-average proportion of older boiler systems, particularly in the multi-family and older single-family stock.
Our Comfort Club maintenance plan covers both your heating and cooling system with seasonal visits — the right way to maintain HVAC equipment in a coastal environment where salt air accelerates wear.
