Reviews
There are currently no reviews.
La Mesa sits just east of San Diego, far enough inland that summer afternoons can get hot, while winter nights can turn cool enough to need steady heat. Hi-Tech Air Heating & Cooling keeps La Mesa homes comfortable with air conditioner and furnace repair, maintenance and installation. Our licensed HVAC professionals service every brand, and as a Carrier dealer we offer a full line of new equipment when it's time to replace.
Understanding Your Air Conditioner
Central air works by moving heat from inside your home to the outdoors. The indoor evaporator coil absorbs heat as the blower moves air across it. Refrigerant carries the heat to the outdoor condenser, where the compressor and condenser coil release it outside. The thermostat starts and stops the cycle. When a capacitor weakens, a motor wears out, refrigerant leaks or the coil gets dirty, your home won't cool the way it should.
Early Warning Signs
Weak airflow, warm air from vents, a system that runs constantly, unusual sounds, water near the indoor unit and a spike in your electric bill are all reasons to have your AC checked before it fails completely.
AC Troubleshooting Tips
- Check that the thermostat is set to cool and below the current room temperature
- Look at the air filter and replace it if it’s dirty
- Check the breakers for the indoor and outdoor units
- Make sure supply vents and return grilles are open and clear
- Look for ice on the copper lines; if you see it, turn the system off and call us
When to Choose AC Repair and Maintenance
Signs You Need AC Repair
| What you notice | What it can mean |
|---|---|
| Banging or screeching | Broken or loose parts, failing motor |
| Warm air | Low refrigerant or compressor problem |
| Frequent on and off | Thermostat, electrical or refrigerant issue |
| Water leaks | Clogged condensate drain |
| Musty smell | Moisture or mold in the system |
| Higher bills | Dirty coils or failing components |
Optimal Times for AC Maintenance
Schedule a tune-up in spring so your system is ready before La Mesa's warmest weather. A clean, adjusted system cools better and uses less electricity.
AC Installation and Replacement
Consider replacing your air conditioner if it is 12 to 15 years old or older, needs repairs every summer, uses R-22 refrigerant or can't keep your home comfortable on hot afternoons. We size each system to your home and install it to manufacturer specifications. Learn more about new installation and upgrades and replacement.
Understanding Your Furnace
A gas furnace uses an electronic igniter to light its burners, which heat a metal heat exchanger. A blower pushes household air across the heat exchanger and through your ducts, while exhaust gases are vented safely outside. Safety controls such as the flame sensor and limit switches shut the furnace down if something isn't right.
Furnace Repair and Maintenance
Signs You Need Furnace Repair
- No heat or lukewarm air
- Frequent cycling on and off
- Banging, rattling or squealing
- A yellow or flickering flame
- A burning smell that doesn’t go away
- Higher 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, check the blower and test for carbon monoxide.
When You Need a New Furnace
A new furnace may be the right choice if yours is 15 to 20 years old, has a cracked heat exchanger, needs a major repair or no longer heats evenly. Newer furnaces are more efficient and provide more consistent comfort.
How We Handle Repairs
We start every call with a full diagnosis, testing electrical components, refrigerant pressures, burners, safety controls and airflow as needed. We explain the problem and give you a price before we begin, then test the system after the repair.
Ductless and Hybrid Systems
For rooms the main system can't reach, or homes without ductwork, a Carrier ductless system provides efficient, room-by-room heating and cooling. We also install hybrid crossover systems with high-efficiency inverter performance.
Thermostats and Controls
A thermostat that is outdated, poorly placed or set up incorrectly can cause uneven comfort and higher bills. We check thermostat operation on every visit and can recommend programmable or smart models.
Indoor Air Quality
Our indoor air quality specialists can test your home's air for dust, pollen, mold and volatile organic compounds and recommend solutions. We also provide air duct cleaning.
Repair or Replace?
Deciding between a repair and a new system comes down to a few factors: the age of the equipment, the cost of the repair, how often it has failed and how efficient it is. As a general guide, if the repair would cost a large share of the price of a new system, or your equipment is near the end of its expected life, replacement is often the better value. Our repair or replace guide walks through the details, and we'll give you an honest recommendation with real prices for both options.
Keeping Your Outdoor Unit Clear
Leaves, dust and overgrown plants can restrict airflow to your outdoor unit and make it work harder. Keep a foot or two of space clear around the unit and trim back shrubs, especially before summer.
