HVAC, Heating & Plumbing Company in San Diego, California

Friar’s Plumbing, Heating, and AC Repair has kept San Diego comfortable for years, sending licensed technicians across the county from Pacific Beach to Rancho Bernardo. Whether you need a same-day furnace repair, a full AC installation and replacement, or a stubborn clog cleared with professional drain cleaning, our team arrives ready to solve the problem the first time. We treat every home along the I-5 and I-15 corridors like our own.

Furnace Installation & Replacement

San Diego’s mild winters don’t mean you can skip a dependable furnace, especially in cooler inland neighborhoods like Tierrasanta and Scripps Ranch. Our licensed technicians size and install energy-efficient systems correctly the first time, keeping your home warm without driving up your utility bill.

Furnace Maintenance

Routine furnace maintenance catches small issues before they become costly breakdowns on the first cold night of the year. Our team inspects, cleans, and tunes up your system so it runs safely and efficiently all season long, wherever you call San Diego home.

Furnace Repair

A furnace that won’t kick on is never convenient, whether you’re in a hillside home near Mission Trails or a condo downtown. Friar’s dispatches experienced technicians who diagnose the problem fast and get your heat running again the same day.

Heat Pump Installation & Replacement

Heat pumps are a smart fit for San Diego’s mild climate, delivering efficient heating and cooling from a single system. Our team helps you choose the right size and model for your home, then handles the installation with precision and care.

Heat Pump Maintenance

Routine maintenance keeps your heat pump switching smoothly between heating and cooling all year, from foggy mornings near the coast to warmer afternoons inland. We check refrigerant levels, clean coils, and inspect components to protect your investment.

Heat Pump Repair

When your heat pump stops heating or cooling properly, comfort disappears fast. Our technicians troubleshoot the issue quickly and carry the parts needed to complete most repairs in a single visit, so your home gets back to normal sooner.

AC Installation & Replacement

Summer heat waves and Santa Ana winds can push an aging AC system past its limit. We help San Diego homeowners choose and install high-efficiency air conditioning sized correctly for their home, so every room stays cool and comfortable.

AC Maintenance

A well-maintained AC system works harder for less money, which matters when temperatures climb in neighborhoods like Mission Valley and Kearny Mesa. Our seasonal tune-ups keep your system running efficiently and help you avoid breakdowns during peak summer heat.

AC Repair

An AC that’s blowing warm air or short cycling needs attention right away. Friar’s technicians arrive with the tools and parts to diagnose and repair most cooling problems on the spot, restoring comfort to your home quickly and affordably.

Ductless Mini Split Installation

Many of San Diego’s older homes in North Park and South Park were never built with ductwork, making ductless mini splits an ideal upgrade. We design and install systems that deliver targeted, energy-efficient comfort room by room without major construction.

Air Duct Cleaning

Dusty canyon winds and coastal humidity can build up inside your ductwork over time, reducing airflow and air quality. Our thorough duct cleaning removes dust, debris, and allergens so your HVAC system runs efficiently and your air stays cleaner.

Attic Insulation

Many San Diego attics are underinsulated, forcing your heating and cooling system to work overtime through hot afternoons and cool coastal nights. We install quality insulation that improves energy efficiency and keeps indoor temperatures more consistent year-round.

HVAC UV Light Installation

A UV light installed in your HVAC system helps neutralize mold, bacteria, and allergens before they circulate through your home. It’s a simple upgrade that improves indoor air quality, especially during allergy season across San Diego County.

Drain Cleaning

Slow or clogged drains are common in San Diego’s older homes, where aging pipes near neighborhoods like Golden Hill and Normal Heights can accumulate buildup over the years. Our team clears stubborn clogs quickly, restoring proper flow without damaging your pipes.

Tankless Water Heater Installation & Replacement

Tankless water heaters deliver endless hot water while taking up less space than a traditional tank, a welcome upgrade for smaller homes near the coast. We handle sizing, installation, and replacement so your household never runs cold.

Water Heater Repair

No hot water in the morning is never good news. Our technicians respond quickly to diagnose leaks, pilot light issues, and heating element failures, getting your water heater repaired and your routine back on track the same day.

Water Heater Replacement & Installation

When your water heater is beyond repair, we help you choose a reliable replacement suited to your household’s size and hot water needs. Our team handles removal and tankless water heater installation or standard replacement safely and efficiently, so you’re never without hot water for long.

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.
