Get answers to common questions about hvac services in Old Lyme, Connecticut.
For a full high-efficiency AC system replacement in Old Lyme, homeowners can expect to pay between $5,000 and $12,000, with the final cost heavily dependent on home size, system complexity, and the chosen unit's SEER rating. Coastal Connecticut's humidity makes proper sizing and installation critical for efficiency. We recommend getting multiple detailed quotes that include removal of the old R-22 refrigerant unit (if applicable) in compliance with EPA regulations.
The optimal times are during the shoulder seasons—late spring (April-May) for AC service and early fall (September-October) for heating service. Scheduling during these periods ensures your system is ready for Old Lyme's humid summers and cold, damp winters, and you'll avoid the high-demand rush periods where wait times are longer. For replacements, fall is often ideal as it allows you to address both heating and cooling needs before winter.
Yes, Connecticut homeowners have access to several valuable programs. Energize CT, sponsored by the state's utilities and the Energy Efficiency Fund, offers rebates for installing qualifying high-efficiency heat pumps, central AC units, and furnaces. Additionally, the federal tax credits for energy-efficient home improvements can apply. A local, licensed HVAC provider in Old Lyme can help you navigate these programs to maximize your savings.
Always verify that the contractor is licensed by the State of Connecticut (License Type S1 or S2) and insured. Given our coastal environment, choose a company with extensive local experience who understands how salt air can affect outdoor units and how older New England homes present unique ductwork and insulation challenges. Check for strong reviews, clear written estimates, and a commitment to proper Manual J load calculations for accurate system sizing.
This is a common concern in Old Lyme, where temperatures can dip into the teens. Standard air-source heat pumps lose efficiency below freezing. The solution is a properly sized cold-climate heat pump (ccHP) model, which is specifically designed for New England winters and can operate efficiently at much lower temperatures. Alternatively, and very commonly here, your heat pump can be paired with a hybrid system that uses a gas or propane furnace as a backup for the most extreme cold spells.
