Mike's Heating & Air Conditioning

My air conditioning went out over the Labor Day weekend, right when temperatures were hitting 117. I called Mike's on Labor Day morning, expecting them to be closed. To my surprise they answered, happened to be in a neighboring city, and even though they weren't open that day, could be at my home within an hour. Thirty minutes later they were here, quickly diagnosed my problem (a bad capacitor) and my AC was up and running again.
Mike was very professional and took the time to show me what had happened and the replacement part he was installing. He is very customer focused and really cared about

Mike was awesome! We had him come out to fix my mom's super old ac last year and he came out immediately. Replaced a part and said it was just a temporary fix because the ac was over 20 years old. This year the ac broke again and we decided to get it replaced. Called Mike up and he showed up within 30 minutes. Replaced the ac, coils, condenser all within 2 days. Saved my mom from being without an AC in the recent heat wave. Not only was he quick with the replacement, but he was very reasonably priced. Thanks again, Mike. Really appreciate it!

Called Mike Saturday evening and he was here Monday morning. Price was affordable, he was on time, and most importantly very honest and trustworthy. Thank you Mike!

Very fairly priced. I've used his company for the last 23 years. Mike has always been courteous, efficent and the best price! I have recommended him to family and neighbors. His staff is friendly and they take extra precautions in keeping everybody safe during the pandemic.

I've called Mike a few times over the years and he's ALWAYS very helpful. We finally had to replace our compressor (after 35 years!) and haven't had any problems since. I just recently called him because it didn't turn on, and he came by within a couple of hours. Turns out it was an electrical issue and he even recommended an electrician to me. Great guy and great service!

I called Mike's on a Saturday morning after my AC unit stopped working the night before. Mike's wife Anna took the call and she was a pleasure to deal with. She arranged for Mike to come out by noon. Mike arrived around 1130 and had my AC fixed and running great within about 15 minutes, after identifying a bad capacitor. Mike was very friendly and even chatted with my two yo son. I'm happy to support a family owned/run Diamond Bar business and I will definitely be calling Mike next time. His price was reasonable and he even gave a one year guarantee. Thanks Mike and Anna!

Our air conditioner was not working in the early morning. I called Mike's at 6:00am and he came out at 7:00 that same morning as promised! He took care of the problem right away. Good guy who was knowledgeable, nice and effective. We are grateful for his speedy response and professionalism.

Replaced a 35 year old furnace and AC which used Freon. Due to Government ban on Freon in 2019 the Feds are allowing for a tax write off on these old units. Got a new unit from Mike. He did a superb job. We are paying less for the electric bill and hopeful off Tax refund.

Mike is the best!!! He is very professional, honest, trustworthy and is always punctual. I not only utilize Mike's Heating & Air Conditioning for personal use, but also for my real estate business. He is knowledgeable about updated codes. Mike always answers his phone calls and will make every effort to accommodate your schedule. I would recommend Mike 5 times over. Thanks Mike for all of your help!!!

Excellent service, very knowledgeable, extremely personable. On a week where every AC company told me I needed to wait a week or more for an appointment. Mike's heating & AC arrived withing 2 hours. Not only did Mike and Brian remedy the issue at hand, but gave me tips on how to prevent the issue in the future, and to keep my eye on potential issues that may occur. Their professionalism, and friendly demeanor, are just a few reasons on why I will be recommending Mike's Heating and Air conditioning to everyone I know who needs AC service.

Over the years I have used Mike and have told all my friends and family this is a family owned company that is so kind thoughtful professional and honest I recommend them so highly to anyone if you need your air conditioning serviced or your heater serviced this is the company to call!!! all your friends all your family this is a good man good family and a lovely family owned business and it shows in the detail and how quickly they respond that they care I wouldn’t call anyone else and if you’re lucky enough to read this you have found the right man for the job. I am not one that takes time

I hired Mike as one of my friends had recommended him to me. My Ac wasn't working due to the heat and he was able to fix it up with honest prices. I would recommend.

Mike came out within a few hours of my initial call to take a look at my A/C unit that had unexpectedly quit the day before. He took one look at it and within 15 minutes he had it back running and cooling like a champ.

My stupidity over trying to save a lizard that had fallen into the unit. I had pulled the top cover off and in doing so allowed a bracket to fall down into the unit and obstruct the fan which then overheated the motor. Thankfully the motor's built in failsafe shutdown went into effect and the unit shut itself down.

Once the bracket was put back in place the motor and fan

Our A/C is leaking water, called mike. And came next morning on time. We have the a/c system installed 12 years ago by Mike.This is the first time we called for service. He flushes the pipe both ways and check the freon, washed the compressor exterior. Told me how to do the simple maintenance. Very nice guy, I would highly recommend their service, good to have this local company.

Mike's AC is the best!!! This guy always goes the extra mile to make sure everything is just perfect. His prices are very fair. I have recommended him to many of my friends and they all love his service. I can not say enough about how wonderful his business has helped us.

Mike to the rescue! Called at 9:30 am, he was here at 3:15 pm same day. This is the 2nd time I have used his excellent service. This time for a different part for my 20+ year unit.

Mike is the best person for any of your heating and air conditioning repairs. After contacting other businesses in the area who wanted to sell you a new air conditioning unit instead of fixing an existing problem he replaced the problem part for a fraction of the price. He is very professional and did a wonderful job. This is the second time I have used his services and will be calling him in the future.

Absolutely horrible attitude and service. I cant believe they could be a part of the walnut community. I have lived here for over 20 years and i cant understand how they can still be in business with their type of incompetent attitude and stuck up service.
