Patrick

I was very happy with the service provided by Patrick. My AC was blowing out hot air. I had been told by Doctor Auto that I needed a new compressor, which was going to be quite expensive. Luckily, I decided to call Your Mechanic. Patrick was very knowledgeable, friendly and courteous. He called a few days before the appointment to ask a few questions so he could be sure to bring the right parts. He arrived on time on the day of the appointment, then spent some time to do a thorough check of the AC system, and informed me that he did not believe I needed a compressor. He fixed a slow leak, did an AC recharge and then added refrigerant. The AC is now blowing very cold air, and he fixed it for a fraction of what I was told by Doctor Auto. I will definitely call Patrick again for future repairs, and would highly recommend him.

I though Jose was great. He was extremely communicative and didn't seem annoyed by my random inquiries. We also had a struggle with getting the correct belt for my water pump replacement and he followed through on multiple fronts to get his hands on one. My only minor complaint was the time between the initial inspection and the work. The first appointment was almost a week away and it would have been awesome if that was a little faster. But the work was great!

First off let me thank Danny for doing such a great job. My clutch feels like butter now (this is a good thing). He called me before the appointment to confirm, let me know of traffic he hit along the way, clarified what I needed to be worked on, and completed the job. Danny is a great asset to YourMechanic!

All about Car Thermostat Replacement

A thermostat is part of the cooling system that regulates the temperature of the coolant in the engine. The thermostat is a metal valve that has a temperature sensor built in. It can either be open or closed. When the thermostat is closed, it keeps the coolant in the engine. When the engine gets to a predetermined temperature, the thermostat opens allowing coolant to circulate. The circulation of coolant prevents the engine from overheating. If the thermostat fails to open, the car will overheat. If the thermostat fails to close, the engine may never reach the optimal temperature (~220F). The thermostat opens and closes many times when the car engine is running. It is the most common component in the cooling system to fail, causing the car to overheat.
