Certified Mitsubishi Electric Ductless & Heat Pump Solutions Across CT

HVAC Contractor in Greenwich, CT -- Certified, 5-Star Rated

5-Star Rated. Same-Day Service. Certified Mitsubishi Diamond Dealer.

Greenwich's Trusted HVAC Contractor

Greenwich homeowners expect a level of professionalism that matches their property, and that’s exactly what Express Home Services delivers. We’re a family-owned HVAC company with a 5.0-star rating and Mitsubishi Electric Diamond Dealer certification — factory-trained technicians who treat a large Greenwich estate with the same care and precision as any home we service.

Greenwich properties often run larger, more complex HVAC systems than the Connecticut average — multi-zone central air, multiple heating units, and premium equipment that requires a technician who actually understands it. We work directly with homeowners, property managers, and household staff to keep those systems running without disruption.

Heat Pump Installation

Modern heat pumps are increasingly common in Greenwich’s higher-end new construction and renovation projects, delivering efficient heating and cooling from a single system with a smaller environmental footprint. We install both Mitsubishi ductless heat pumps and central ducted systems.

Ductless Mini Split Systems

For additions, pool houses, guest cottages, or finished spaces that a central system can’t reach, ductless mini splits offer precise, quiet, high-end comfort control. As a certified Mitsubishi Electric Diamond Dealer, Express installs to manufacturer spec with the certification most contractors in this market simply don’t carry.

Heating Services

Heating Services

  • Furnace repair and replacement — all major brands, all fuel types
  • Boiler repair and replacement — steam and hot water systems in Greenwich’s older, established homes
  • Heating tune-ups — a fall inspection recommended before peak winter demand
  • Emergency heating service — a failure in winter gets priority, no exceptions

Our Comfort Club maintenance plan covers annual AC and heating inspections at a discounted rate, with priority scheduling that fits a busy household’s calendar.

Greenwich properties often carry higher-end, more complex equipment than the Connecticut average, and our technicians treat every visit with the discretion and professionalism a premium property calls for — coordinating directly with homeowners, property managers, or household staff, whichever works best for your schedule.

Spring is the right time for an AC tune-up before summer demand peaks, and fall is the right time for a furnace or boiler inspection before winter arrives. Homeowners on our Comfort Club maintenance plan get both automatically, at a discounted rate, with priority scheduling built in so you’re never trying to book a technician during the busiest week of the season.

Serving Greenwich and Lower Fairfield County

Greenwich sits at the southwestern edge of Connecticut along the Long Island Sound, bordering Stamford and the New York state line. Our team covers this stretch of Fairfield County as part of our regular service route.

We also serve Stamford, Norwalk, Fairfield, and Bridgeport. From waterfront estates to established residential neighborhoods, our technicians handle the full range of premium and standard systems Greenwich properties have.

Within Greenwich, our technicians regularly work across the town’s full range of neighborhoods, from waterfront properties along the Sound to estate properties further inland. We’re accustomed to larger properties with multiple mechanical rooms or zoned systems spanning a main house and separate structures, and we plan service visits with that scale and complexity in mind from the first call.

A full system replacement on a larger Greenwich property is a significant expense, and we’re direct about that. For homeowners weighing a new multi-zone system, heat pump conversion, or premium mini split installation, $0 down financing for qualified applicants means the decision doesn’t have to be rushed. We’ll walk you through the numbers alongside the detailed estimate, not as a separate sales conversation.
