Smart thermostats from Ecobee, Nest, and Honeywell Home offer occupancy sensing, geofencing, and learning algorithms that adapt to your schedule automatically. Our technicians verify system compatibility, install the required wiring, and configure the device for optimal interaction with your specific HVAC equipment.
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.
Indoor air quality suffers when ductwork harbors years of accumulated particulate matter, allergens, and biological growth. Thorough duct cleaning addresses every branch run, main trunk line, and register boot using agitation tools and high-powered vacuum extraction to restore clean airflow.
Professional AC tune-ups follow a multi-point inspection protocol covering thermostat calibration, condensate drain clearing, electrical connection tightening, and evaporator coil cleaning. Maintaining clean coils and proper superheat readings keeps your system running at peak rated efficiency.
HVAC emergencies do not follow business hours, and a failed system in extreme temperatures puts your household at risk. Our technicians carry common replacement parts including capacitors, contactors, ignitors, and fan motors to resolve most failures in a single visit and restore comfort fast.
Comprehensive HVAC inspections cover thermostat operation, ductwork condition, refrigerant levels, electrical connections, and combustion safety. This detailed assessment identifies efficiency losses, safety hazards, and components nearing end of service life before they result in costly emergency repairs.
Replacing an aging HVAC system with properly sized, high-efficiency equipment can reduce energy costs by 30 to 50 percent. Professional installation covers equipment selection, ductwork modifications, refrigerant line installation, electrical upgrades, and thorough commissioning to verify rated SEER and AFUE output.
Ductless mini-split systems deliver zoned comfort without invasive ductwork, making them ideal for additions, garages, and older homes. Professional installation includes refrigerant line routing, condensate management, and electrical circuit provisioning to achieve rated SEER performance up to 33 in top models.
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.
Boiler systems demand specialized knowledge of hydronic circuits, expansion tanks, pressure relief valves, and combustion analysis. Our technicians diagnose issues ranging from kettling and low water pressure to faulty zone valves and circulator pump failures across gas, oil, and electric units.
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.
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.
Heat pumps rely on a precise balance of refrigerant pressure, electrical components, and airflow to deliver efficient heating and cooling year-round. Professional repair addresses compressor hard starts, frozen coils, faulty thermostatic expansion valves, and auxiliary heat lockout conditions.
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.
KIC Refrigeration is trusted by property owners throughout Concord (pop. 44,862) for a simple reason — we do what we say we are going to do. No inflated repair estimates, no recommending replacements when a repair will do, and no disappearing after the invoice is paid. We are here for the long term and our reputation across Concord reflects that commitment to honesty.
Our commitment to the Concord community goes beyond HVAC service. We hire locally, support New Hampshire suppliers when possible, and stand behind every installation and repair with warranties that actually mean something. When your heating or cooling system needs attention, choose the company that Concord homeowners already trust with their comfort.
Built on NATE certification, transparent pricing, and a guarantee that we stand behind.
If the repair does not solve the problem or the installation does not perform to specification, we come back and make it right at no additional cost. Our guarantee covers workmanship, parts, and system performance because half-finished work is not in our vocabulary.
You receive a written estimate with itemized parts and labor costs before any work begins, and the final invoice matches. No diagnostic fees hidden in the repair bill, no surprise surcharges — just honest pricing you can verify and trust.
HVAC failures do not wait for business hours and neither do we. Our emergency technicians are dispatched around the clock — nights, weekends, and holidays — so you never go without heat in winter or cooling in the peak of summer.
Every technician on our team holds current NATE certification — the highest standard in the HVAC industry for installation and service competency. You get a technician who has passed rigorous exams on system diagnostics, refrigerant handling, and equipment commissioning.
We service Carrier, Trane, Lennox, Rheem, Goodman, Daikin, Mitsubishi, York, Bryant, and every other major residential and commercial HVAC brand. One call handles any system regardless of manufacturer, refrigerant type, or equipment age.
Common questions about HVAC service, costs, and what to expect when you call.
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 Concord, 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 Concord 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.
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 New Hampshire locations. For Concord 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.
The National Air Duct Cleaners Association recommends professional duct cleaning every 3 to 5 years for most Concord homes. However, several factors can shorten that interval: households with pets that shed, family members with allergies or asthma, smokers in the home, and properties that have undergone recent renovation or construction work should consider cleaning every 2 to 3 years. Warning signs that your ducts need attention include visible dust or debris accumulating at register openings, musty or stale odors when the system runs, unexplained respiratory symptoms, and inconsistent airflow between rooms. Our NADCA-compliant cleaning process uses truck-mounted vacuum equipment and rotary brush agitation to remove dust, allergens, mold spores, and debris from your entire duct system. We also inspect for disconnected joints, damaged insulation, and air leaks that reduce system efficiency.
HVAC repair costs in Concord 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.
