Furnace Replacement in a Clairemont Mesa Split-Level

BeforeAfter

The homeowner had a 38-year-old Lennox that had tripped the rollout switch twice in one week. We pulled the old unit, corrected the flue slope that was trapping combustion gases, and set a new Trane S9V2 in place with a sealed filter cabinet. The utility closet went from rust-flaked and sooty to clean, quiet, and safe. That furnace gets a written 365-day guarantee on the whole installation.

AC Repair That Saved a July Weekend in La Mesa

BeforeAfter

A family in La Mesa woke up to an 88-degree upstairs on a Friday morning. The condenser fan was humming but not spinning. Our technician found a failed dual-run capacitor and a contactor with burned contacts, both replaced same day, along with a hard-start kit for the aging compressor. The house was back to 74 by mid-afternoon. Total repair came in under $300 with the written price handed over before a tool was opened.

Ducted Heat Pump Retrofit for a Point Loma Bungalow

BeforeAfter

Point Loma homes near the water carry salt air that eats coil fins. This 1940s bungalow had a dead furnace and a 25-year-old AC with corroded coils. We removed both and installed a Carrier 38MURA ducted heat pump, which runs on one outdoor unit and pushes warm or cool air through existing ductwork. The result is a year-round system that handles Point Loma’s damp, mild winters and uses far less electricity than the old setup.

AC Condenser Replacement After a Salt-Air Failure in Chula Vista

A Chula Vista homeowner near the Otay River bottom had a Goodman condenser with fins crumbling to the touch. Salt and moisture had eaten through the coil in six years. We installed an American Standard Silver 14 with a coastal corrosion kit and elevated the pad to keep standing water off the base. The old unit ran at 11 SEER; the new one runs at 14 SEER and coasts through east county’s hot, dry afternoons.

Clogged Condensate Line Cleaning in Normal Heights

The ceiling stain in this Normal Heights bungalow was the giveaway. The evaporator coil’s condensate line had clogged with algae and dust, backing water into the ceiling drywall. We vacuumed the line, flushed it with a microbial cleaner, and installed a float switch that kills the AC if the drain ever backs up again. Water alarms and one wet patch of drywall were the full extent of the damage. The whole call took under two hours.

Furnace Ignitor and Flame Sensor Service in North Park

A North Park condo owner called with a furnace that would light intermittently on December mornings. The ignitor had hairline cracks, and the flame sensor was coated in baked-on carbon. We replaced the ignitor with an OEM-equivalent part, cleaned the sensor with a proper abrasive pad, and verified the flame signal on our meter. That repair ran $190 total, written guarantee included, and the heat lights on the first try every time since.
