These guys came and installed a gas valve on our 40 year old furnace. And went over and above and even put a new filter on. Very professional. Highly recommended. Best in town .

I had a pool heat pump issue and the pool company recommended them.
Let me start with the positive. Everyone I dealt with was extremely nice and friendly. When they thought they knew what was wrong they said if it didn’t work they would charge me after the initial service call.
However, the tech that came out checked pressures but didn’t check anything electrical. He said it was the thermostat. I called the manager and said I’m fine with trying it as long as someone else comes out to install it so they could verify that they thought it was the thermostat. Well the original tech showed up

If I could give this company 0 stars I would. I have never been so unhappy with a company in my life. My dad has owned his own business for 20 years and with the customer isn't happy, he always makes it right. With this company it is all backwards. My husband and I had them come out to our house and the technician was new and a little unsure about the decisions he was making but he left and later that night the problem was back. We called back to get some of the money back since he didn't fix the problem and we needed to go with a different company. Talked to the manager and it was the worst customer

Will always makes sure we get great service. They have done a lot of work for different family memebers of mine and a lot of commercial work for us. Always fair and honest!

After my experience with ML, I had to find a way to leave a public review. My mom is 78 years old living alone. She's concerned about the age of her furnace, so Hal Mullins came out to do an inspection and give an estimate for a replacement furnace. After we discussed the furnace further with my mom, she decided to wait and see if she could get another year out of her old one. On his first visit, Hal noticed a loose handrail on my mom's basement steps. He told her he would fix it. A week later, he called her to see if she was home so he could swing by and repair the handrail! She said she tried

I'm the pastor of Columbus West Church of God. In my tenure here as pastor we have gone through 3 different heating companies to service our 9 furnaces. It has been our experience that ML is the best we have worked with. They are prompt in getting out and meeting our needs. The air conditioners and furnaces that we have had to replace have been less expensive than other companies. The service has been awesome and very prompt in handling some of the difficult situations of our building. I recommend them to whoever is in need of furnace or air conditioning work.

Horrible Customer Service. Tried for 2 weeks just to get a return phone call or email for a quote. Girl that answers the phone knows nothing, claims someone will call me back and never does. Great to see a business so busy they don't need new customers. Good for them.
