AC and Furnace Repair and Installation in San Diego, CA

San Diego's weather changes a lot from the coast to the inland neighborhoods. Homes near the ocean deal with salt air and marine-layer humidity, while homes further inland see hotter summers and cooler winter nights. Wherever you live in the city, Hi-Tech Air Heating & Cooling can keep your air conditioner and furnace running well. We provide repair, maintenance and installation for both, our licensed HVAC professionals service all brands, and as a Carrier dealer we offer a complete line of new equipment.

Understanding Your AC System

A central air conditioner moves heat out of your home. The blower moves indoor air across the evaporator coil, where refrigerant absorbs heat. The compressor pumps that refrigerant to the outdoor condenser coil, where a fan releases the heat outside. The thermostat starts and stops the cycle. Problems with any of these parts, from a weak capacitor to a refrigerant leak or a dirty coil, reduce cooling and raise your energy bills.

Troubleshooting Tips for Your AC

• Set the thermostat to cool and check the batteries
• Replace a dirty air filter
• Check the breakers for the indoor and outdoor units
• Open closed vents and clear blocked returns
• Clear leaves, sand and debris from around the outdoor unit
• Turn the system off and call us if you see ice on the lines

When to Opt for AC Repair and Maintenance

Indicators for AC Repair

What you notice	What it may mean
Warm or weak airflow	Refrigerant leak, failed capacitor, dirty coil
Loud banging or screeching	Loose or broken parts, failing motor
Frequent cycling	Thermostat, electrical or refrigerant problem
Water near indoor unit	Clogged condensate drain
Musty odor	Moisture or mold in the system
Corrosion on outdoor unit	Salt exposure near the coast

Optimal Times for AC Maintenance

Spring is the ideal time for an AC tune-up. We clean the coils, check refrigerant, test electrical parts, clear the condensate drain and service the filter. Coastal homes benefit from extra attention to coil cleaning and corrosion.

AC Installation and Replacement

Consider a new air conditioner if yours is 12 to 15 years old or older, uses R-22 refrigerant, needs frequent repairs, is heavily corroded or can't keep your home comfortable. We size each system for your home and install it to manufacturer specifications. See new installation and upgrades and replacement.

Introduction to Your Furnace System

A gas furnace starts when the thermostat calls for heat. An inducer motor clears the flue, an igniter lights the burners and the burners heat the heat exchanger. The blower then moves household air across the heat exchanger and through your ducts. Safety controls, including the flame sensor and limit switches, shut the furnace down if something isn't right.

When to Pursue Furnace Repair and Maintenance

Signs You Need Furnace Repair

• No heat, or cool air from the vents
• The furnace turns on and off frequently
• Banging, rattling or squealing
• A yellow or flickering flame
• A burning smell that lingers
• Rising gas bills

Ideal Times for Furnace Maintenance

Schedule furnace maintenance in early fall. We clean and inspect the burners, test the igniter, flame sensor and safety controls, inspect the heat exchanger and venting, and test for carbon monoxide.

When Furnace Installation or Replacement Is Needed

Consider a new furnace if yours is 15 to 20 years old, has a cracked heat exchanger, needs expensive repairs or no longer heats evenly. A new high-efficiency furnace uses less fuel and provides more consistent comfort. If your air conditioner is also aging, replacing both at once can improve efficiency and simplify the installation.

How We Handle Repairs

We diagnose every problem before we recommend a fix. Our technicians test electrical components, refrigerant pressures, burners, safety controls and airflow as needed, explain what they found and give you a price before starting. After the repair, we test the system to make sure it's running properly.

Repair or Replace?

Age, repair cost, repair history and efficiency all factor in. If a repair would cost a large share of a new system, or your equipment is near the end of its life, replacement is often the better value. Our repair or replace guide covers the details.

Ductless and Hybrid Systems

A Carrier ductless system is a great way to heat and cool homes without ducts, additions and rooms that never stay comfortable. We also install hybrid crossover systems with high-efficiency inverter technology.

Comfort Across Different Neighborhoods

Because conditions vary so much across San Diego, we tailor our recommendations to your home. Near the coast, we focus on corrosion, humidity control and efficient heating for cool evenings. Inland, we focus on cooling capacity for hot afternoons and keeping outdoor coils clean of dust.

Indoor Air Quality

Our indoor air quality specialists can test for dust, pollen, mold and volatile organic compounds and recommend solutions. We also offer air duct cleaning.

Thermostats and Safety

We check your thermostat on every visit and can recommend programmable or smart models. On every furnace repair we test for carbon monoxide. Keep working CO detectors on every level of your home, and if you smell gas, leave and call your gas utility from outside.
