HVAC Services in San Dimas

NATE-certified technicians providing the complete range of heating and cooling services.

Mini Split Repair

When a mini-split displays error codes, produces weak airflow, or fails to reach setpoint, the fault often lies within the inverter board, thermistor sensors, or refrigerant circuit. Professional repair restores rated SEER output and eliminates the inefficient short cycling that drives up utility costs.

Smart Thermostat Installation

Professional smart thermostat installation goes beyond mounting and Wi-Fi pairing. Technicians verify your system has the necessary common wire, confirm compatibility with multi-stage heating and cooling equipment, and program setpoints and schedules tailored to your household for immediate energy savings.

Heat Pump Installation

Selecting the right heat pump means matching BTU capacity to your structure while accounting for climate zone, insulation levels, and existing ductwork. Professional installation ensures proper refrigerant charge, correct defrost timing, and verified auxiliary heat staging for demanding winter conditions.

HVAC Inspection

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.

Air Duct Repair

Leaking and disconnected ductwork wastes up to 30 percent of conditioned air before it reaches living spaces, forcing your HVAC system to work harder and driving up energy costs. Professional duct repair seals joints, replaces damaged sections, and restores proper static pressure balance.

Furnace Tune-Up

Scheduling professional furnace maintenance each fall ensures your heating system delivers full BTU output without wasting fuel. Technicians inspect the inducer motor, verify pressure switch operation, calibrate gas valve output, and clean the burner assembly for reliable cold-weather performance.

HVAC Installation

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.

Mini Split Installation

A professionally installed mini-split eliminates the energy losses associated with traditional ductwork while providing independent temperature control per zone. Technicians mount indoor heads at optimal height, route linesets with proper insulation, and commission each zone for verified heating and cooling output.

Emergency HVAC Repair

When your heating or cooling system fails unexpectedly, rapid diagnosis is critical to minimizing discomfort and preventing secondary damage like frozen pipes or heat-related illness. Emergency technicians isolate the fault, whether electrical, mechanical, or refrigerant-related, and execute repairs on the spot.

Heat Pump Repair

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.

Dryer Vent Cleaning

A dryer that takes multiple cycles to dry clothes or feels excessively hot to the touch signals a restricted vent line. Technicians clear lint accumulation using rotary brush systems and compressed air, then verify exhaust velocity meets manufacturer specifications for safe, efficient operation.

AC Tune-Up

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.

Air Duct Cleaning

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.

Boiler Repair

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.

AC Repair

Air conditioning failures range from simple capacitor replacements to complex compressor and refrigerant circuit repairs requiring EPA Section 608 certified handling. Our technicians diagnose the root cause using superheat and subcooling measurements, amp draws, and pressure readings to restore full cooling output.

Answers to the heating and cooling questions our customers ask most often.

What HVAC brands does KIC Refrigeration install in San Dimas, CA?

KIC Refrigeration installs and services all major HVAC equipment manufacturers in San Dimas 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.

Can a smart thermostat really save money in San Dimas?

Yes. The EPA estimates that Energy Star certified smart thermostats save San Dimas homeowners an average of 8 percent on heating and cooling costs annually, which translates to $50 to $150 per year for a typical household. Models from Ecobee, Nest, and Honeywell Home use occupancy sensors, geofencing, and learning algorithms to build a schedule around your actual habits, automatically lowering temperatures when you leave and restoring comfort before you return. Many smart thermostats also provide energy usage reports, filter change reminders, and maintenance alerts that help you keep your system running efficiently. Some California utility providers offer rebates of $50 to $100 on qualifying smart thermostat purchases, further reducing the cost. KIC Refrigeration installs and configures smart thermostats to communicate properly with your specific HVAC system — including multi-stage equipment and heat pumps that require specialized wiring.

Is a heat pump better than a furnace for San Dimas homes?

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 California locations. For San Dimas 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.

Does KIC Refrigeration offer financing for HVAC installations in San Dimas?

Yes. KIC Refrigeration offers flexible financing options for HVAC installations in San Dimas, CA, including low-interest plans, deferred interest same-as-cash programs, and extended payment terms that make it easier to invest in high-efficiency equipment without a large upfront cost. Approved applicants can often finance a complete system replacement for less than $100 per month. We also help San Dimas homeowners identify and apply for available financial incentives including utility company rebates on high-efficiency equipment, manufacturer promotional pricing, and federal tax credits such as the 25C Residential Clean Energy Credit which provides up to $2,000 for qualifying heat pump installations and up to $600 for qualifying furnaces and air conditioners. Between financing, rebates, and tax credits, the effective cost of a new high-efficiency HVAC system is often significantly lower than the sticker price.

Can a new HVAC system lower my energy bills in San Dimas?

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 San Dimas, 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.
