Air Conditioning Repair & Installation
When humid Fairfield County summers push a Stamford system past its limit, CELCO repairs and installs central air, coils, condensers, and thermostats with clear pricing before work begins, including careful duct and sizing work when an older system needs more than a quick swap. Explore air conditioning services or call 203-371-0055.
Heat Pumps, Ductless & Go Hybrid
Heat pumps and ductless mini-splits can provide efficient cooling in summer and heating in shoulder seasons, with hybrid options that keep a furnace or boiler as backup. Ask about available heat-pump incentives: qualifying 5-ton systems can save up to $8,150.* We will help you check current eligibility.
*Up to $8,150 example is for a qualifying 5-ton system replacing oil, propane, natural-gas or electric-resistance heat, completed Sept 1 to Dec 31, 2026. Eligibility and program rules apply, and amounts may change. See Rebates & Incentives for details.
