A/C & Heating
Blowing warm in July or cold in January? We find the actual fault instead of just topping it off.
When the air won't blow cold in summer or the heat won't come up on a frozen morning, your day gets miserable fast — and a windshield you can't defrost is a safety problem. Tom's Mobil Service keeps Roseville drivers comfortable and their glass clear year-round, and we fix the real cause instead of topping off refrigerant and sending you out to be back in three weeks. Call 651-489-7807 or book online.
Signs your A/C or heat needs attention
- Air blowing but never getting cold (or never warm)
- Weak airflow on the highest fan setting
- A musty or sweet smell when it runs
- The defroster taking forever to clear
- Knocking, squealing, or rattling at startup
- Cabin temperature drifting hot and cold on its own
We diagnose the real cause first
We don't guess. We check system pressures, test the compressor and electrical side, scan for leaks with the right tools, and look at the heating side too — coolant, thermostat, and flow — then quote upfront.
- Measure high- and low-side pressures
- Leak-detect with UV dye / electronic tools
- Test compressor, clutch, and controls
- Inspect coolant, thermostat, and heater core
What we repair
- Refrigerant recharge with a proper leak check
- Compressor, condenser, evaporator, and lines
- Cabin air filter
- Blend doors and actuators
- Heater core, thermostat, cooling-system repairs
- Electrical and control faults
Heat and defrost, not just A/C
Cold-weather comfort runs through the cooling system — thermostat, coolant, heater core, blend door. Clearing your windshield fast isn't a luxury; it's how you see. We service both sides of the climate system.
All makes and models
Domestic, Asian, and European vehicles, to manufacturer specs with quality parts — your climate system gets the right fix, not a generic one.

Frequently asked questions
Why is my A/C blowing warm?
Usually a low charge from a small leak, but it can be the compressor, a clogged filter, or an electrical fault. We test to find the real cause.
Can you fix my heater and defroster too?
Yes — heat issues trace to the cooling system, and we service the whole climate system.
How much does A/C repair cost in Roseville?
Depends on the cause; we diagnose first and quote upfront. Call 651-489-7807.
How long does it take?
Many A/C and heat repairs are same-day.
Do I need a yearly A/C check?
It's the cheapest way to avoid a breakdown — it catches low charge and small leaks early.
