We offer expert automotive repair, radiator repair, and auto air conditioning services.

Our radiator and cooling specialists are experienced in a variety of radiator repair services, including flushing out radiator and cooling systems, repairing leaks and other damage to copper/brass and aluminum/plastic radiators, checking thermostats and fixing broken hoses or cracked belts. We can also check for corrosion and debris. While performing automotive services, we may spot and address potential problems that will help prevent emergency auto repair problems down the road.

One of the most appreciated luxuries of any vehicle is the automotive air conditioning system. There is nothing better than being able to flip on your vehicle’s AC unit to keep you cool. At the same time, there is nothing worse than your AC system not functioning properly during hot weather. Knowing where to take your vehicle if you find yourself sweltering from a problematic automotive AC unit can be extremely helpful.

If you find that your automotive AC system is not working correctly or that it’s not as cold as it used to be, Gill’s Auto Repair is the right place. At Gill’s, our certified AC repair technicians have the experience to diagnose and repair your auto air conditioning system.

With years of auto repair experience and knowledge, we have the ability to fix all types of automotive air conditioning malfunctions. Whether it’s an AC compressor replacement or a simple AC recharging service, we can get your vehicles cooling system functioning properly again.
