DO NOT USE CARTERS! They have came out multiple times to my 81 yr old inlaws house since September,…read morenever fixed the HVAC system which keeps freezing up and not heating. This week after the 4th visit (and over $300 paid) they told the tech that we would need to call someone else if it isn't resolved, he responds "then call someone else!" and walked out. We ended up having a local company that I use repair it today and they did a great job, the valves and screen were clogged and they never even checked this issue at all. Would never recommend this people and they need an attitude adjustment.

I very much appreciate their honesty and waiving the cost even though it was not their fault. They are still currently helping me to get the leak fixed and I am very happy with their service. I would highly recommend their services. -Rob C.

First time reviewer (shame on me) multi-time customer. I have used MCS almost exclusively since…read moremoving to the mountain over 15 years ago. They have worked on my HVAC units repair and maintenance along with plumbing. My most recent was a repair to a flexible water supply line to a water heater that failed causing water damage. I was without water entirely to the whole house, so no flushing or washing hands, etc. I contacted MCS first thing in the morning and by noon that day Clarence (plumber) had fixed the problem. Clarence quickly evaluated the problem and offered a few solutions explaining the differences (cost, maintenance, expected longevity...) also identified the year of the water heater and its expected life span. In under two hours he had finished the job and explained everything he had completed including an extra shutoff valve I asked for mid service. Clarence was quick, knowledgeable, easy to talk to, patient with questions, clean and very kind. I recommend MCS to all my friends

In a couple hours they sent out a technician who correctly diagnosed and fixed the problem in record time. He also checked the rest of the system to make sure it was actually cooling.
