Heating and air conditioning service built around San Leandro
We keep licensed, background-checked technicians on the road in San Leandro and the surrounding 94579 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
Homes in Alameda County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
The busiest week of our year in San Leandro is the first stretch of sustained may weather. Systems that idled all season fail in clusters.

San Leandro94579 HVAC questions, answered
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in California, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
How often should I change my filter in 94579?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in San Leandro with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in San Leandro, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
How quickly can a technician get to San Leandro?
For the 94579 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
What does a new system cost in San Leandro?
A complete residential replacement in the 94579 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Are your technicians licensed and insured?
Every technician dispatched into San Leandro is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
