HVAC Installation & Service reviews in Durham
Hear from Durham homeowners about their experience with local hvac installation & service companies.
Called on our way through LI Sound, had an issue with refrigeration. Matt was available on short notice and was great problem solver, made sure the repair was done right. Fair price.
Outstanding service. Kevin and Matt are professional, knowledgeable and personable. They solved multiple cooling and heating problems quickly and efficiently.
We called Kevin on an extremely hot day with a forecast of a heat wave for the next 3 days and he came within hours of our call. He was quick to fix and knows his profession well! Just Awesome service! Thanks Kevin. It is nice to have a reliable local person in our small community! You are the best!
Kevin and his team came to install a new furnace for our home. Our old furnace had some quirky plumbing and wiring, but Kevin and his team came back multiple times (more than he was anticipating when he started) to resolve all the issues and get the new furnace running. His services we a good value, especially compared to the other quotes we got. Thank you!!
Kevin came out on short notice and worked tirelessly in the brutal heat to get our central AC up and running. As it is an older machine we thought we might need a whole new unit, but he was able to make repairs with minimal parts and ensured us it still had some longevity left. If you are looking for an honest, pleasant professional with very reasonable rates look no further than Kevin!
Very reliable, knows how to solve any problem.
HVAC Installation & Service performance guide for Durham, Connecticut
Climate averages are state-level reference values, not city-specific measurements.
Climate impact in Durham, Connecticut
Durham, Connecticut sits in a Cold climate zone with average summer highs near 80°F and winter lows near18°F. Those swings load the evaporator coil, blower motor, refrigerant lines, and condensate drain. Keep a clean MERV filter to protect the compressor.
Extended heating cycles strain heat exchangers and blower motors. Inspect ignition systems and combustion safety annually.
Most common local breakdowns
Heat exchanger stress and ignition issues in gas furnaces during long winters.
Frozen coils caused by restricted airflow and dirty MERV filters.
Low airflow from dirty MERV filters or a weak blower motor causes ice. Ask for airflow and refrigerant superheat checks.
Equipment recommendation
A cold-climate heat pump or high-AFUE furnace with SEER2 15+ AC keeps both heating and cooling efficient across seasons. Seal ductwork and schedule coil cleaning to protect the heat exchanger, capacitor, and compressor.
Furnace + AC setups need annual heat exchanger inspection, verified combustion, and balanced blower airflow.
Local code and housing notes
Ask contractors about Connecticut energy code compliance and permits. Older homes often benefit from ductless mini-splits to reduce line-set length and improve zone control.
Mechanical permit for system replacement and condenser swaps.
Post-install inspection covering refrigerant line pressure and condensate drain routing.
Load calculation proof to avoid short-cycling compressors.
Airflow verification (blower motor speed + static pressure).
Always confirm a contractor's license and insurance before hiring.
