HVAC reviews in Simi Valley, California

Great service. This is an honest shop. They tell you straight and do not try to sell you service you do not need. Refreshing!!

So helpful! Was very nice, efficient, and did his job well :) Love this auto repair store!

Love these guys ,they have always taken care of us with our cars ,honest , reliable and knowledgeable in mechanics....great crew , thanks H&M.

Professional technicians do excellent service work. Cost of work close to estimate. Owner Marcel great mechanic.

Set up an appointment a few days back and when I arrived, they told me that they were not going to be able to fix the car in the timeframe that was given. H&M Auto did not try and work with me or give options. Just canceled.

Thermostat unresponsive. Rewired the terminal connections and secured everything. Problem fixed.

Came in under quote. Car runs great. Done in a timely fashion. Unbelievably personable. Definitely recommend. This is my new shop.

Been coming here for a long time due to the great job they do on our vehicles. Honesty and integrity is what I feel this company is all about. Thank you Marcel and staff!!

Marcel and crew are honest amazing kind mechanics who know there stuff and have been doing this for many yrs my parents have been going to them for 35 yrs

Burning smell from vents during heat. They cleared debris in the heat exchanger and changed the filter. No more smell since.

Only half the vents worked. Tech located a collapsed duct and replaced it. Now airflow reaches every room again.

They have always done a great job over 10 years plus that I've been going to them, stand behind their warranty and don't nickel and dime me or make up problems. I have had nothing but great experiences every time.

Cooling dropped randomly. Found a refrigerant leak and patched it. Refilled and tested the unit—cooling holds stable again.

Furnace smelled gassy. They checked for leaks and tightened loose fittings. Everything tested safe.

In all honesty I don't think there is a better place to get your tires and brakes done. As a person that relies on a limited income, Jum and his guys really are awesome. I have never felt like I was taken advantage of or felt their estimates were way off.

Heat pump failed in freezing weather. Found a broken defrost sensor. Replaced it, and the unit now works in all temperatures.

Heating took too long to start. Adjusted gas pressure and cleaned burners. Warm air starts flowing within minutes now.

So happy I found this place. Came from another shop nearby with a terrible experience and this place made my car issues stress free. He really tries to get to the root of the problem versus just trying to get money out of you. I truly appreciate my experience here.
The last place was ready to replace the part, quoted me with $2,000 worth of work and talked to me disrespectful, this place looked into things further and discovered the part only needed to be cleaned, so thankful.

I brought a 2007 Ford Edge in to have the spark plugs replaced, they were suspected of causing a missing/surge when driving the vehicle. Normally I would do this myself, but I just moved out here and don't have a good garage setup or all the right tools out here yet. I met Hector, the manager, and explained the situation. He stated they would hook it up to a scanner, drive it and call me before anything was done. Shortly after I got home, he called and nothing obvious was found, but agreed on the plug replacment as a logical step. He quoted an amount. It was quite a bit of work since you have to take the intake off, and all the air handling pieces to get to the cylinders in the back, next to the firewall since it's a transverse v-6. I agreed to proceed. He pointed out that it would make sense to replace the three coils on the back side, so the intake wouldn't have to be removed again if the coils were the issue, and had two options for coils. I checked the pricing online, and his pricing on the coils was very competitive. I agreed with this approach; replace the three in the back while the top of the intake was off so it wouldn't need to be done a second time later. The next day he called it was done. He had all the old parts for me, and suggested I keep the removed coils in case one of the front coils went bad. Again, a great idea to help minimize the cost. The surging issue was resolved, the plugs were in very bad shape it was obvious from looking at them they had never been changed. The final cost was what I was quoted. Great transaction; solid quote, final cost matched the quote, they did the work like I would have, they saved money where they could. I would highly recommend H and M Auto. I'll be going back here for anything I think they could work on for me.

My brakes failed and needed to replace brake pads, calipers, rotors and a grease seal. Ive owned my truck for over 20 years and my brakes have never worked so well. After the job was done they showed me the parts they took off my truck and explained what happened. I will definitely come back to this shop if other issues come up.

My car was making noise due to bad wheel bearing. Manny was genuine in providing the estimate and repaired / replaced it in no time. He was very professional, thorough and honest in his work. I would definitely recommend this shop.
