We want to make sure that every car ride is a comfortable one. At Mechanic Northwest, we offer comprehensive air conditioning services to keep your A/C running smoothly. We’ll take care of everything so you can focus on the road ahead.

Car Heater Repair

The only thing that rival’s your vehicle’s A/C in terms of importance is the heater. Without a functioning heater, driving can be miserable and even dangerous. Don’t suffer through a cold winter in your car. Let us help you stay warm and cozy all season long!

Services We Offer

Mechanic Northwest offers car heating and cooling services to keep you comfortable all-year-round. Our team of experienced mechanics will inspect, diagnose, and repair your system to ensure it’s properly running. 

We offer a variety of services, including:

  • A/C Diagnostics and Repair

We start with a full-system check, including all hoses, connections, and other components to check for leaks or damage. We also perform state-of-charge test. Our techs also use a manufacturer-approved electronic leak detector.

  • Antifreeze Adjustment

Over time, your car’s antifreeze level can become low. This can cause your vehicle to overheat, so it’s important to keep an eye on the antifreeze level and top it off when necessary.

  • Coolant Flush and Replacement

The coolant eventually becomes contaminated and needs to be replaced. We can perform a flush of the system and replace the coolant with fresh, clean fluid.

  • Thermostat Repair and Replacement

A faulty thermostat can throw off your car’s heating and cooling system. If you notice any issue with your thermostat, our technicians can test it and make any necessary repairs. We can also provide a replacement if needed.

  • Heater Core Repair and Replacement

The heater core is responsible for circulating hot coolant to heat the cabin. If your heater doesn’t work, it’s a sign that the heater core needs to be repaired or replaced.

  • Regulator and Compressor Check

The compressor is responsible for pressurizing the refrigerant while the regulator controls the amount of refrigerant that flows through the system. If either of these components isn’t functioning properly, it can cause major issues with your car’s A/C.

I usually go to pep boys.. but the customer service there has gone down A LOT. They quoted me $1100 for what they thought needed to be done. And if I still liked pep boys I would’ve paid that but then I thought I better give my money to a shop I actually like. I went to mechanic northwest and they were soooo helpful and nice and I can tell they weren’t trying to take advantage of me or overcharge me. Which me being a young girl is usually what happens at mechanic shops. They were so transparent and kept me in the loop the entire time. The lady even took the time to explain everything and show me videos of what was done. If you’re tired of big corporate chain mechanic shops, give these guys a try. I love small family owned businesses. I ended up paying way less than what pep boys was going to charge me And my car runs great! Also I had just taken my car to pep boys a couple months ago and paid $1700 and they said I should have no more problems.. just to end up with my car having trouble again after 3 months. So yea it was time for a change. I highly recommend this shop!

I have only been in Washington for a few years and was looking for a small shop with quality work and fair prices. Called Mechanics Northwest and scheduled a diagnostic. They promptly assessed the issues and provided a quote. Repairs were completed earlier than promised and within the quoted cost. I am happy to have found a shop for all my future repair needs!!

This place deserves the highest of reviews. This is my second car I have taken to them right after purchasing them, without a doubt I get very well taken care of. The guys are very professional and Alnurfo is super knowledgeable and respectful. If your looking into getting your car fixed the right way the first time this is defined the place to go to.

From the moment I met the owner of Mechanic Northwest in the rear of the shop in the parking lot until I drove away fully satisfied that my 2008 Infinity FX35 had its brake job completed ✅ I was treated with respect and friendliness in the process of doing professional work. I definitely feel that I picked the right shop to do business! Thank you for such a pleasant experience. It was totally stress free. I fully trust these people to do work on all my vehicles in the future. And I highly recommend their service. Thankful for Mechanic Northwest!! They cared about my 🚘 !

Very nice people and very thorough. They made sure I knew what was wrong with my car and even went above and beyond to give my dealership an estimate of how much the repairs would cost.

I have an oil change every 4 to 6 months. I recently moved to Fed Way and needed to find a new place. I came across this shop and made an appt. My car seems to run better after having my oil changed here. Not sure what oil they used but I definitely feel a difference in my car. I'm taking it back for a recommended fluid flush. My car is an 07 so I'm sure it needs fresh fluid.

Brought my car in to get the power window fixed (came off the track) and an inspection, got it back same-day. Great service, communicative, friendly and courteous front desk staff. Will be going back if my car ever needs new repairs.

Again, Mechanic Northwest came through for our family when our older truck broke down. They were able to quickly diagnose the problem and call to discuss what can be don. They continue to be reasonably priced & have a fast turn around. I know I can count on them to take care of our vehicle needs.

Over heated on the side of the highway and got towed here. These guys got me in right away, diagnosed the problem, fixed it, and got me on the road in no time at a fair price. They were extremely friendly and transparent. I hung out in the garage with them while they worked on it. Definitely recommend their services.
