HVAC, Heating & Plumbing Company in La Jolla, California

Many La Jolla residences pair original plumbing with newer additions, and that mix can leave some rooms too warm while pipes in others show their age. Our team handles AC maintenance before summer visitors fill the Village, routine seasonal heat pump maintenance for year-round efficiency, and full furnace installation when an older unit finally fails. We work cleanly, wear shoe covers indoors, and leave every room ready for guests.

Furnace Installation & Replacement

We help you compare furnace efficiency and cost, then complete a tidy install that covers the duct connections, gas lines, venting, and final testing.

Furnace Maintenance

A full furnace tune-up lubricates movable parts, checks carbon monoxide safety, and cleans the blower so warm air flows freely on those chilly nights.

Furnace Repair

Whether the pilot keeps going out or your furnace blows chilly air, our technicians pinpoint the failing component and complete repairs that same day.

Heat Pump Installation & Replacement

Heat pumps pair well with solar panels and electric homes, and our installers cover the sizing, mounting pads, line sets, and all thermostat settings.

Heat Pump Maintenance

We tune heat pumps twice a year, tightening contacts, measuring refrigerant levels, and rinsing the outdoor coil so you can avoid big midseason fixes.

Heat Pump Repair

Ice on the outdoor unit, harsh grinding, or rooms that never reach temperature indicate heat pump trouble that our technicians resolve with real care.

AC Installation & Replacement

Upgrading an aging air conditioner lifts comfort and savings, and our crew installs quiet, high-SEER systems that are sized right for your whole home.

AC Maintenance

Routine AC service checks the temperature split, cleans the blower wheel, and clears the drain line so your system cools evenly without wasted energy.

AC Repair

When your thermostat says cool but the home stays warm, our AC repair team checks the capacitors, contactors, and refrigerant to restore even comfort.

Ductless Mini Split Installation

We install ductless mini splits in guest suites, home offices, and backyard casitas, giving every space its own peaceful zone for heating and cooling.

Air Duct Cleaning

Air duct cleaning lifts out dust, debris, and drywall residue left behind from renovations, so every vent delivers cleaner air into your living areas.

Attic Insulation

New attic insulation seals in comfort, eases strain on your HVAC system, and keeps the top-floor bedrooms from getting overly hot on sunny afternoons.

HVAC UV Light Installation

We add ultraviolet light systems to your HVAC equipment to stop biological growth on the coils, a worthwhile upgrade for allergy and asthma sufferers.

Drain Cleaning

Slow or smelly drains rarely fix themselves, so our plumbers use camera inspections and strong cleaning tools to restore full flow through every line.

Tankless Water Heater Installation & Replacement

We size tankless water heaters to handle your household’s peak demands, so multiple showers and appliances can run at once without water turning cold.

Water Heater Repair

Our water heater repair service handles gas valves, anode rods, and sediment flushing, extending the life of your tank and keeping hot water reliable.

Water Heater Replacement & Installation

If repairs no longer make sense, we suggest a right-sized replacement, install it to local code, and test the temperature and pressure before leaving.

What Your Neighbors Are Saying About Us

What a great company! You can tell by the incredible employees. I needed to get both a new AC and Heating unit. They educated me so that I had options and learned what I needed vs. what I didn't need aka helping me save a lot of money! They gave me and incredible price along with incredible service and they worked really hard to get the job done quickly for me. I highly recommend!

Friars was fantastic. I took a long time to decide what to do with our house because we needed everything: a new furnace and new AC, and I was stunned at the sticker shock of all the estimates I had. Everyone suggested mini splits for our house, but Alex and Carlos really took the time to explain both the benefits and downsides to all the different options.

Wow!! A+ 5 Stars ⭐️ We got a brand new ac installed and furnace moved up to attach. Friars team was AMAZING! From the first consult to the end of service installation. Rick was super polite and informative regarding the system. Friars was the first quote we received and I cancelled all appts after with other companies. They are professional, polite and provide a quote on the spot.

Hands down, great company. Fair price. Straight forward. The technician was prompt and polite. Everything was professionally 10/10 would recommend!

Friars just completed replacing my furnace and air condition. The installers are 1st rate. They are polite, went right to work, finished on time and patiently explained how to use the equipment …very professional. I would recommend Friars with Mora and his team anytime.

Wonderful customer service and professionalism. Very impressed with the whole process from initial phone call with Jennifer, to the install of new AC and furnace, to the complimentary tune up 6 months later.
