AC Repair and Service in New Haven, CT

New Haven’s housing stock is some of the oldest in Connecticut. From the three-family homes in the Westville and Beaver Hills neighborhoods to the older walk-up apartments and single-family colonials in East Rock and Fair Haven, a significant portion of this city’s residential HVAC systems are aging — and aging systems fail when temperatures push into the 90s. That is when we get called.

AC Repair — All Makes and Models

Our AC repair technicians service central air conditioning systems, ductless mini splits, and heat pump systems throughout New Haven. When you call, a technician comes to diagnose on-site and gives you a written estimate before any work begins.

Common AC repairs we handle in New Haven:

  • Refrigerant leaks and recharges — one of the most common calls in older New Haven homes. Low refrigerant means your system runs longer and cools less.
  • Capacitor and contactor replacement — these electrical components fail regularly in aging systems. Inexpensive to fix when caught early, but a failed capacitor can burn out the compressor if ignored.
  • Frozen coils — caused by restricted airflow or refrigerant problems. The system blows air but stops cooling.
  • Compressor failure — a more serious repair. We diagnose whether repair or replacement makes better financial sense and give you the honest comparison.
  • Blower motor and fan issues — loud noises, reduced airflow, or a system that runs but does not move air are often motor-related.
  • Thermostat and electrical faults — sometimes the AC is fine and the thermostat is the problem. We check the full system before replacing anything.
  • Emergency AC repair — same-day priority service for systems that have stopped working entirely. Call early and we will make every effort to be there the same day.

AC Installation in New Haven

For New Haven homeowners whose systems are beyond economical repair, or whose homes have never had central air, we install new systems sized correctly for the home’s layout and insulation level.

We offer honest guidance on whether repair or replacement makes financial sense. A 14-year-old system with a failed compressor in a New Haven triple-decker is usually a replacement conversation — we will walk you through why and present the numbers clearly.

Financing is available for new installations. If upfront cost is a barrier to replacing an end-of-life system, $0 down financing options are available for qualified applicants. Learn more about HVAC financing.

Ductless Mini Split Systems in New Haven

Many New Haven homes — especially the older multi-family housing stock and homes with finished spaces that lack ductwork — are ideal candidates for ductless mini split systems. A mini split can cool and heat individual rooms or zones without requiring any duct installation.

Express Home Services is a certified Mitsubishi Electric Diamond Dealer, which is the highest level of factory certification available for Mitsubishi HVAC products. We install and service Mitsubishi mini split and heat pump systems throughout New Haven. Most HVAC companies in Connecticut are not Diamond Dealers — certification requires factory training and verified installation standards that Mitsubishi audits directly.

Heating Services in New Haven

Connecticut heating season runs longer than most people plan for, and New Haven’s older housing stock includes a large inventory of oil-heated homes, steam boilers, and aging furnaces. When heating systems fail in January or February, we treat it as the emergency it is.

Our heating services in New Haven include:

  • Furnace repair and replacement — all major brands, natural gas, propane, and oil
  • Boiler repair and replacement — steam and hot water systems are common in New Haven’s older homes
  • Heat pump installation — a growing option for New Haven homeowners looking to reduce dependence on oil heat
  • Annual heating tune-ups — fall inspections before the heating system is under full winter demand
  • Emergency heating service — when a system fails in the middle of winter, we prioritize those calls

Our Comfort Club maintenance plan covers annual AC and heating inspections and is designed for homeowners who want consistent maintenance without having to remember to book each season. Members also receive priority scheduling and repair discounts.

HVAC Service FAQs for New Haven

We also offer preventive maintenance through the Comfort Club plan. Whatever your home or property needs for heating and cooling, we handle it.

Do you offer same-day AC repair in New Haven?

Yes. For most AC repair calls in New Haven, we offer same-day service. Call us at (860) 606-4872 in the morning and we will schedule a technician for that day whenever our schedule allows. For true emergencies -- AC completely failed in a heat wave, no cooling and vulnerable household members -- we prioritize those calls at the front of the queue.

My AC is old. Should I repair it or replace it?

The general threshold most technicians use: if the repair cost is more than 50% of a new system's installed price, and the existing system is over 12 years old, replacement usually makes better financial sense. We will give you the actual numbers on both options during the diagnostic visit. There is no pressure -- the goal is to help you make the decision that makes sense for your home and budget.

Do you offer financing on new HVAC systems in New Haven?

Yes. For new system installations -- central air, furnace replacement, heat pump, or mini split -- $0 down financing is available for qualified applicants. See our financing page for current terms. If an aging system needs replacement and upfront cost is the barrier, financing makes it manageable.

Yes. Express Home Services is a Mitsubishi Electric Diamond Dealer, which means our technicians are factory-certified to install and service Mitsubishi mini split and heat pump systems. If you are considering a ductless mini split for a New Haven home without ductwork, or a heat pump upgrade to replace oil heat, working with a Diamond Dealer ensures the installation is done to manufacturer spec and the warranty is fully in force.
