Our ASE-certified A/C technicians perform a checklist inspection of your complete air conditioning system and provide a written report.
What We Do
Our standard auto air conditioning performance and diagnostic check includes:
- Visual inspection of accessible air conditioner parts and components

- System pressure test
- System control test
- Leak detector test*
*Some difficult-to-find leaks may require an optional color dye leak detection test, which has an additional cost.
Common Problem
One of the most common auto air conditioning problems is a dirty cabin air filter. These filters clean all the air that enters your passenger compartment and need to be replaced regularly. If the air coming from the vents in your car smells stale, moldy, or damp—or the airflow is weaker than normal—the cabin air filter likely needs replacement.

Protect The Environment
The Federal Environmental Protection Agency (EPA) regulates the type of refrigerant you can use in your auto air conditioner and how it is handled. Your Ann Arbor, MI auto AC service technicians follow strict environmental rules for properly removing, recycling, and disposing of used refrigerant gas to protect the environment while keeping you cool. At Hoover Street Auto Repair in Ann Arbor, MI, we install high-quality replacement parts and refrigerant. Using cheap, counterfeit refrigerant gas can destroy your auto air conditioning system. Give us a call at (734) 913-6272 and let us help you keep your cool.
Auto Air Conditioning - Best Invention Ever!
It's the first hot day of summer. You turn on your car's A/C only to discover an unwelcome blast of warm air from the vents. That's when you phone Hoover Street Auto Repair, your Ann Arbor auto air conditioning service and repair specialists.
Increase Fuel Mileage
Did you know your auto air conditioning system loses 5% to 10% of its refrigerant (and cooling capacity) every year? With reduced cooling power, your AC has to run longer to cool your vehicle, which decreases your fuel mileage. A regular auto air conditioner service can help restore your fuel efficiency.
Lower Repair Costs
Refrigerant gas loss is normal, but without regular automotive A/C maintenance, your auto air conditioning system has to work harder to cool your vehicle. Making the A/C system work harder wears out parts faster and increases your repair costs. An auto air conditioner service can significantly lower your auto A/C repair cost.
Simple Fix
There is a simple fix for decreased fuel mileage and high A/C repair costs: a yearly A/C system check and refrigerant refill keeps your A/C system working at top performance. Schedule an appointment with one of our trained automotive A/C repair technicians—they understand every aspect of auto air conditioner repair and service, from computerized components to environmental disposal requirements.
Routine Maintenance
Most of us in Ann Arbor, MI, don't give our auto air conditioning a second thought as long as it's producing cold air. But your auto air conditioner is a complex and expensive system that should be cared for before it fails.
Besides keeping you cool, regular auto A/C refrigerant recharge has another major benefit. Refrigerant gas absorbs moisture from air that leaks into the system, which can turn the refrigerant into a corrosive acid. This acid damages internal parts and creates very expensive repairs. Fresh refrigerant protects your air conditioning components and keeps your AC system operating at peak efficiency, lowering fuel costs and keeping you cool.
The refrigerant gas in your air conditioner also contains a special oil that lubricates the internal A/C parts. A small amount of this oil escapes with normal refrigerant gas leakage. When enough oil leaks out, your auto air conditioner still produces cold air, but the internal parts no longer have enough oil to protect them. This results in increased wear and eventual component failure. To prevent this, it's important to service your auto air conditioning system regularly.
Your vehicle's air conditioning system plays an important part in passenger comfort and safety. It is responsible for cooling, heating, defrosting, air filtering, and humidity control. It keeps you comfortable during the hot summer and ensures a clear view of the road in the damp, cold winter months. The automotive air conditioning system is a great convenience that is often taken for granted.
At Hoover Street Auto Repair, we can check your vehicle's air conditioning system to make sure it's functioning properly and provide service if needed. Our ASE Certified technicians are experts at auto air conditioning recharging and can pressure-gauge the system, recycle used refrigerant, check A/C pump drive belts, and perform an auto air conditioning performance test. It's the best way to make sure you can beat the heat in cool comfort all summer long.
Prevent Expensive AC Repairs
Even with regular service, A/C parts wear out over time. Normal wear and tear eventually affects all moving parts, but catching problems early can save you from extensive repairs. For instance, a common part that wears out is the compressor shaft seal. When it fails, refrigerant gas leaks, and the system cycles on and off more frequently to keep you cool. This frequent cycling wears out the clutch that drives the A/C compressor, as well as the compressor itself. Wait too long to replace a leaking seal, and you'll face a very expensive repair bill for premature failure of the A/C clutch and compressor.
Annual AC Inspection
An annual inspection of your air conditioning system helps prevent costly repairs. Inspection and preventive maintenance can make a real difference in repair costs, so don't wait. Get your AC checked today.
Your vehicle owner's manual will tell you how often your auto A/C system should be serviced. Hoover Street Auto Repair's service advisor will be happy to provide service recommendations and answer your questions.
