Why maintaining your AC System is very important:
Heating and A/C systems may break eventually with usage, hose pipes may clog and drip if not serviced, causing reduced efficiency heating and cooling capabilities. Regular maintenance will keep your AC system operating at peak performance!

Indications your A/C system may be having issues:

• If your air conditioning blows only slightly cooler air compared to the exterior air
• Air that blows in smells damp, musty, or like mildew and mold
• Your cabin does not warm up in cold weather, or is just a little warmer than outside
• The defroster takes longer than typical to operate, or does not operate
• Your heater or A/C only functions when driving, not when idling, or quits blowing when the car is stationary
• Your heating system blows cold air, or the air conditioning blows warm air
• Low airflow even at the highest fan setting.

A comprehensive evaluation of heating and A/C system includes:

• Examining the internal controls and blower
• Checking radiator coolant operating temperature, hoses, pressure radiator cap and thermostat
• Inspecting the compressor belt
• Inspecting system and seals for leaks or various other damages.
• A cooling system pressure test
• Verifying the A/C pressure meets manufacturer specifications
• Measuring the interior vent air temperature

Our repair and maintenance services include:

Belts
The fan belt, also referred to as a drive belt, connects your vehicle's engine to its front-mounted accessories. This belt is responsible for rotating the water pump and engine fan, ensuring a cool engine environment. Unfortunately, over time, your vehicle's fan belts can dry out and develop cracks, requiring a replacement.

Coolant System Flush
A car's coolant system transfers excess heat from one part of the engine and dissipates it through the radiator fins. As time goes on, the coolant can become old and contaminated, negatively impacting the system's performance. To maintain optimal system function, consider regular coolant system flushes as part of your vehicle's cooling system maintenance.

Hoses
Hoses have the crucial role of transferring coolant and antifreeze throughout the engine's cooling system, including the radiator. With time, these hoses can dry out and develop cracks, leading to leaks. When it's time for replacement, you can rely on our team of experts for your vehicle repair needs.

Radiator Flush
Your vehicle's radiator is responsible for keeping the engine cool and safeguarding it from excessive heat. Sludge, rust, and other solid deposits can accumulate inside the radiator, leading to clogs and reduced system efficiency. This, in turn, can negatively affect your vehicle's performance. Incorporating regular radiator flushes into your routine car maintenance schedule is essential.

Radiators
Radiators serve as heat exchangers, cooling your car's internal combustion engine. They accomplish this by circulating engine coolant through the engine block and then releasing the heat into the atmosphere through radiation.

Coolant FAQs

When should I do a coolant flush?

Your vehicle's owner's manual will recommend getting the coolant flushed about every 30,000 miles or three to five years, whichever comes first. Make sure to consult your owner's manual as some outline a more specific interval depending on the vehicle's make and model and your driving habits.

Why is my coolant leaking?

Corrosion within the radiator is the leading cause of a coolant leak. As the radiator tubes get older and weaker, sediment or debris collects inside and causes a leak. The sealing gasket between the tank and the radiator can also wear out, and lead to a leak.

Why is my coolant light on and what should I do?

If the dashboard light is red, indicating your car is overheating then you should pull over as soon as it is safe to do so and switch off the engine. If the coolant level is low or there is another problem with your cooling system, you could cause serious damage by continuing to drive.

Radiator FAQs

What does radiator service include?

Radiator service starts with draining the system. Then we flush the radiator and engine block, inspecting all hoses to make sure they're not cracked. Next we refill the radiator with fresh coolant and finish by pressure testing the radiator cap and cooling system.

What is the average lifespan of a radiator?

While radiators usually last 8-10 years, some factors can shorten their lifespan. Watch for signs of deterioration to know when replacement is needed.

Why is my car engine overheating?

The most common reason a car overheats is a lack of coolant or a coolant leak. However, if you have an older vehicle, it may also indicate that it is time to replace your radiator, thermostat, water pump or heater core. If it continues to be a problem that you can't fix, your best bet is to bring it to our shop in Lake Geneva.

Great people! We were traveling with my wife, daughter and our 8 year old granddaughter when the car overheated in the afternoon on a hot day. Mike's Auto pulled the best mechanic off another job to analyze the problem, a leaky fitting. They were not able to get the part the same day, but filled the car with a gallon and half of antifreeze and hoped we'd make it home. Here is the part that sets them apart. He wouldn't accept any payment, just shook hands and wished us safe travels. I'm so impressed. I'm 84 and had lost faith in this kind of old school kindness.
