Clogged dryer vents are a leading cause of residential fires, with lint buildup restricting exhaust airflow and causing the dryer to overheat. Professional cleaning removes compacted lint from the full vent run, verifies proper airflow velocity, and inspects the exterior termination for damage.
A professional HVAC inspection evaluates the complete system from furnace combustion and heat exchanger integrity to air conditioning refrigerant charge and electrical safety. Technicians document equipment age, efficiency ratings, and any code violations to give you a clear picture of system health.
Ductless mini-split systems require specialized diagnostics for inverter-driven compressors, electronic expansion valves, and multi-zone communication boards. Our technicians resolve issues including refrigerant leaks at flare connections, blinking error codes, frozen evaporator coils, and failing fan motors.
Installing a mini-split system correctly requires precise wall penetration, vacuum-sealed refrigerant lines, and proper electrical isolation between indoor and outdoor units. Our technicians size each zone independently using BTU calculations to ensure consistent temperature control across every room.
Maintaining safe and efficient boiler operation requires precise attention to water chemistry, flue gas temperatures, and combustion efficiency. Professional repair addresses leaking heat exchangers, malfunctioning aquastats, air-bound radiators, and ignition system failures to restore rated AFUE output.
An annual air conditioning tune-up catches refrigerant leaks, worn contactor points, and degraded fan motors before they cascade into compressor damage. Technicians measure temperature differential across the coil, verify amp draws, and confirm proper subcooling to protect your investment.
Restoring reliable air conditioning performance requires more than replacing visible parts. Technicians measure refrigerant pressures, check compressor winding resistance, test run and start capacitors, and verify condenser fan operation to ensure every component of the cooling circuit functions within specification.
A comprehensive furnace tune-up includes combustion analysis, heat exchanger inspection, and verification of gas pressure at the manifold. Technicians clean burners, test flame sensor microamp readings, and confirm proper flue draft to maintain safe, efficient operation throughout the heating season.
Clean ductwork directly impacts the efficiency of your HVAC system by reducing static pressure and allowing unrestricted airflow to every register. Our technicians inspect for microbial growth, seal access points after service, and verify airflow improvements with anemometer readings post-cleaning.
Upgrading to a modern heat pump delivers dual-mode heating and cooling from a single system, with top-tier models achieving 10+ HSPF and 20+ SEER2 ratings. Proper installation includes Manual J load calculations, refrigerant line sizing, and electrical panel verification for reliable year-round comfort.
Full HVAC installation requires coordination of heating equipment, cooling components, ductwork design, and control systems to deliver efficient comfort at rated capacity. Our technicians perform Manual J and Manual D calculations, size equipment to match your structure, and commission the system to manufacturer standards.
Ductwork problems manifest as uneven room temperatures, excessive dust near registers, and HVAC systems that run continuously without satisfying the thermostat. Technicians identify crushed flex runs, separated joints, and deteriorated mastic seals using pressure testing and visual inspection protocols.
Upgrading to a smart thermostat enables precise scheduling, remote access, and energy usage reporting that can reduce heating and cooling costs by 10 to 15 percent. Professional installation ensures correct wiring to your HVAC system, including C-wire verification and multi-stage equipment compatibility.

The ideal time for HVAC replacement in Stonington is during the shoulder seasons — spring and fall — when demand is lower, equipment availability is highest, and scheduling is more flexible. Contractors are less booked during these periods, which means faster installation timelines and potentially more competitive pricing. You are also more likely to find manufacturer rebates, utility incentive programs, and promotional financing during off-peak months. From a technical standpoint, moderate temperatures allow your new system to be commissioned and tested under less extreme conditions. However, KIC Refrigeration completes HVAC installations year-round in Connecticut and can often start within days of your approved estimate, even during peak summer or winter demand. If your current system is showing signs of failure, do not wait for the perfect season — a planned replacement is always better than an emergency one.
Absolutely. Modern high-efficiency HVAC equipment can reduce heating and cooling costs by 20 to 40 percent compared to systems installed 15 or more years ago. The improvement comes from advances in compressor technology, variable-speed motors, and smarter controls. In Stonington, upgrading from a 10-SEER air conditioner to a 16-SEER2 or higher unit delivers substantial monthly savings — the higher the SEER2 rating, the less electricity consumed per BTU of cooling. On the heating side, replacing an 80-percent AFUE furnace with a 96-percent modulating furnace means that 16 cents of every heating dollar previously wasted up the flue now heats your home. Heat pumps offer even greater efficiency, delivering 2 to 4 times more heating energy than they consume in electricity. KIC Refrigeration calculates projected energy savings for any equipment upgrade so you can see the return on investment before making a decision.
KIC Refrigeration installs and services all major HVAC equipment manufacturers in Stonington including Carrier, Lennox, Trane, Daikin, Goodman, Rheem, York, Bryant, American Standard, Mitsubishi, and Fujitsu. For ductless mini split systems, we specialize in Mitsubishi, Daikin, and Fujitsu units which are the market leaders in inverter-driven technology. We are not locked into a single manufacturer or distributor, which means our recommendations are based entirely on what best fits your home size, budget, efficiency goals, and existing infrastructure. Each brand offers different warranty structures, SEER2 ratings, and feature sets — from basic single-stage units to premium variable-speed communicating systems. Our NATE-certified technicians install every unit strictly to manufacturer specifications and register all warranties on your behalf.
We recommend professional HVAC maintenance at least twice per year for Stonington homeowners — once in spring to prepare your cooling system and once in fall to prepare your heating system. Each tune-up includes a comprehensive multi-point inspection covering filter replacement, refrigerant level verification, electrical connection tightening, thermostat calibration, condensate drain clearing, and performance testing. For the heating check, technicians also inspect the heat exchanger for cracks, test safety switches, and verify gas pressure on furnaces and boilers. Routine maintenance catches small problems — like a failing capacitor or a dirty flame sensor — before they cause complete system failures. Industry data shows that well-maintained HVAC systems last 15 to 20 years compared to 10 to 12 years for neglected equipment, and they operate 15 to 25 percent more efficiently throughout their lifespan.
Heat pumps offer both heating and cooling from a single outdoor unit, making them significantly more energy-efficient than furnaces for moderate climates. A heat pump does not generate heat — it transfers it from outdoor air, which requires far less energy than burning gas or running electric resistance coils. Modern cold-climate heat pumps with variable-speed inverter compressors operate effectively down to minus 15 degrees Fahrenheit, making them viable in most Connecticut locations. For Stonington homeowners with natural gas access, a dual-fuel system — heat pump for primary heating paired with a gas furnace for backup during extreme cold — often provides the best balance of efficiency and performance. Heat pumps also qualify for federal tax credits under the Inflation Reduction Act. KIC Refrigeration evaluates your specific climate zone, insulation levels, and utility rates to determine whether a heat pump, furnace, or dual-fuel system is the smartest investment.
HVAC repair costs in Stonington typically range from $150 to $500 for minor fixes such as capacitor replacement, contactor swaps, or thermostat wiring issues. Mid-range repairs like blower motor replacement or refrigerant recharging run $500 to $1,200. Major repairs — including compressor replacement, heat exchanger repair, or evaporator coil swap — cost $1,200 to $2,500 or more depending on equipment brand and system type. The final price depends on whether you have a furnace, heat pump, air conditioner, boiler, or ductless mini split, as parts and labor vary significantly between system types. Our NATE-certified technicians diagnose the issue accurately on the first visit, and KIC Refrigeration provides a written estimate with transparent pricing before any work begins. We never charge a diagnostic fee when you proceed with the recommended repair.
