When a furnace will not light on a cold December morning or the AC quits during a warm September afternoon, the first question is simple: what is wrong, and what will it cost to fix? Our technicians start with a careful diagnosis, explain what they found in plain words, and give you the price before any work begins.
Heating and cooling for East Bay homes
Most homes we visit in San Leandro and San Lorenzo were built in the post-war decades, with a gas furnace in a hall closet or garage and ductwork running through the attic or crawlspace. Many have added central air since then, and more owners are now replacing an aging furnace and AC pair with a heat pump or adding ductless mini-splits to rooms the ducts never reached.
That mix shapes the work:
- Furnace repair — ignition and flame-sensor faults, pressure switches, blower motors and limit switches cause most no-heat calls between November and March.
- AC repair — failed capacitors, dirty outdoor coils, clogged condensate drains and refrigerant leaks are the usual reasons a system runs without cooling.
- Heat pump repair and mini-split repair — defrost problems, sensors and communication faults on inverter equipment.
- Duct repair and duct cleaning — crushed or disconnected runs in older attics are a common reason one room never gets comfortable.
- Maintenance — a yearly check before the season keeps small problems from turning into emergency calls.
Appliance repair under the same roof
We also repair the appliances that keep a household running: refrigerators, ranges and ovens, dishwashers, washers, dryers and wine coolers, including premium brands such as Miele, Wolf, Viking, Thermador and Gaggenau.
How a visit works
- Call or book online. Tell us what the equipment is doing — the noise, the error code, the room that stays warm. Phone support is available 24/7.
- Diagnosis. The technician tests before replacing anything: airflow, electrical readings, gas and safety controls on HVAC equipment; sensors, pumps and control boards on appliances.
- Upfront price. You see the repair price and the options before work starts. The diagnostic fee is waived when you go ahead with the repair.
- Repair and check. After the repair the system or appliance is run and checked, and the repair carries a 90-day warranty.
Where we work
Our office is at 699 Lewelling Blvd in San Leandro. We serve San Leandro, San Lorenzo and Castro Valley, including Ashland and Cherryland. Keeping a small area means shorter drive times and a better chance of same-day service.
