Old equipment costs you more than it saves.

Aging systems run less efficiently, break down more often, and drive up utility bills. If yours is getting up there in years, we can help you plan a replacement before it becomes an emergency.

How a job with B.C. actually goes

Three steps, one person handling all of them — from the first phone call to the system running in your house.

01

Free consultation

Joel comes out, looks at your space and your existing equipment, and tells you straight what it actually needs — not what's easiest to sell.

02

Custom install

Equipment sized to your home, permits pulled where required, ductwork done properly. No shortcuts, no subcontracted crews you've never met.

03

Long-term care

Maintenance and repairs down the road come from the same person who installed it — not a call center routing you to whoever's free.

Services

Everything from a rattling furnace to a full dual-fuel system, handled by one licensed crew.

Repair

Heating and AC repairs diagnosed right the first time, so it stays fixed.

Installation & Replacement

New systems sized to your home — not the biggest unit that happens to be on the truck.

Mini-Split & Ductless

Cooling and heating for garages, additions, and rooms your main system can't reach.

Heat Pumps

Efficient heating and cooling from a single system, in a climate built for it.

Gas Furnaces

Installs, tune-ups, and repairs on gas furnace systems.

Dual-Fuel Systems

Heat pump and furnace paired together for year-round efficiency.

Air Duct Work

Ductwork sealed, sized, and routed the way it should have been the first time.

Maintenance

Seasonal check-ups that catch small problems before they turn into expensive ones.

25 years in the trade. One name on the invoice.

Joel Butler learned heating and air conditioning the way most good tradespeople do — in attics, crawlspaces, and every kind of San Diego rooftop, long before he opened B.C. Mechanical.

He still does the estimating, the installing, and the follow-up himself. That means the person who designs your system is the same person who shows up when you need it serviced five years later.

  • Licensed (#1129116), bonded & insured
