Auto A/C & Heating Services

Is your vehicle's air conditioning or heating system not keeping up with the weather? Don't let the temperature in your vehicle make you miserable. Come visit Northwest Automotive LLC in Defiance, OH 43512 and we'll get you comfortable again.

Even if your heat or A/C is working at reduced efficiency, it's still worth a visit to Northwest Automotive LLC. That's because heating and A/C systems may break eventually with usage, and hose pipes may clog and drip if not serviced. Let us examine your vehicle and keep your systems working at top performance. Call us at 419-782-7827 to learn more about how we can get your air conditioning or heating up and running again!

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:

Air Conditioning
Have you been sweltering in your vehicle lately? Perhaps your car's air conditioner isn't functioning properly. At Northwest Automotive LLC we have qualified service professionals who can fix your air conditioner. To have an air conditioning system serviced, repaired, or replaced by experts consider visiting Northwest Automotive LLC. You can also call us at 419-782-7827 with any questions relating to your vehicle's air conditioner.

Belts
A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on Northwest Automotive LLC for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit Northwest Automotive LLC today. The mechanics at Northwest Automotive LLC will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

Coolant System Flush
A car's air conditioning system contains a coolant which transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the a/c coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 419-782-7827 or visit Northwest Automotive LLC in Defiance, OH 43512 for all your coolant system flush and fill needs. Ensure maximum performance from your vehicle's heating and cooling systems today.

Hoses
Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on Northwest Automotive LLC for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit Northwest Automotive LLC today. The mechanics at Northwest Automotive LLC will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

Radiator Flush
A radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust and other solid deposits build up inside your car's radiator. These make the cooling system become clogged and less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make radiator flushing a part of your routine car maintenance schedule. For all your radiator flush needs, call 419-782-7827 or visit Northwest Automotive LLC today.

Radiators
Radiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. To have your radiator needs handled by experts, visit Northwest Automotive LLC today.

Summerize Your Vehicle
It's important to prepare your car for the perils of summer - heat, dust, traffic jams - which increase the likelihood of a breakdown. At Northwest Automotive LLC in Defiance, our technicians can perform the necessary preventive maintenance to get your car ready for summer. These are some of the recommended services:

  • Check the battery
  • Change the fluids
  • Examine the belts and hoses

What Our Customers Are Saying

Early Saturday morning, we were heading home to Minnesota and our car started making grinding noises. Called Tim and he said bring it in. Discovered we needed a new air conditioner compressor and he installed it and had us back on the road right away. It was a 12 hour drive home and we felt happy, cool and comfortable. Thanks Tim!


-Sharon Snyder

Extremely trustworthy and knowledgeable, with fair rates. Absolutely recommend this shop! You won't be disappointed.


-Jennifer Holman

My family has always gone to Northwest Automotive. We enjoy their great work, great deals, and friendly staff. I needed an alternator on an emergency. The shop owner found me an alternator after hours and willingly installed it to get us back on the road at a reasonable price. Always my first choice when recommending professional automotive repair.


-Sarah Doeden

Thanks so much for making our car safe, and doing it for an afforadable price.


-Madalyn Hasselschwert

Great service!


-Kevin Kaskel

The guys here are awesome! The fuel pump in my 99 Firebird went bad. They had my car towed to their place, diagnosed the problem, and had the fuel pump and the serpentine belt fixed within a few days. Will be recommending this place to all my family and friends!


-Jillian Graham

My daughter's car was making a horrible clacking noise from the engine. I trailered it to Northwest Automotive, and they took one listen and knew it was mechanical in nature. The worked really hard to quote a good price, find a used engine, and even offered to arrange financing. We chose not to repair the car at this time, and they didn't charge us for the effort they put in. I would definitely recommend these guys for any auto repair need.


-George Schaffer

My experience at Northwest Automotive has always been good. They have always gotten me in quickly and fixed whatever I needed for a reasonable price! I would definitely recommend doing business there. Specializing in engine repairs and all your other needs!


-Cassy Jennings

Our van's check engine light came on Friday evening. We planned to leave Sunday after church for vacation. So, Saturday morning I call up Northwest Automotive to see if they could fit me in. They said come on in. When I arrived, they ran the standard diagnostic test to find what tripped the light. It turned out to be an extremely simple fix, and they had me back on the road in 10 minutes, which was fantastic because I had two toddlers in tow. The best part? They charged me nothing! At dealerships, I've paid $50+ for them just to run this test.


-Eric Moquin

Great service and great guys that know what they're doing. And, they get it done fast and right!


-Justin Reed

Awesome work! These guys know automobiles and have all the professional tools to do any job, big or small. Take your vehicle in or give them a call. OUTSTANDING WORK!
