Andrea S.

Excellent customer service with professional technicians. Called on HMS for years now, my expectations are always exceeded. Highly recommend!

Barbara J.

Great! Just moved to Newcastle, called spoke with Christy and Erik was here in no time. Did a great job! From phone call to end north, friendly courteous and friendly, courteous and made sure we were taken care of. Keepers! We will definitely use HMS when the need arises.

Whitney W.

I cannot recommend them enough!!! I’ve had them do 2 jobs for me and they were both done perfectly. The first job another well known Norman company quoted me $1500 “to start” which would take 10 hours. I called HMS and he did the whole job in 3 hours and charged $350. They’re so honest! I would never call another company.

Yvonne J.

Nathan did a great job of fixing my air condition. He has a great work ethic and his education serves him well.

Ashley C.

Awesome customer service, very prompt, professional, and extremely knowledgeable in fixing any problems! I would recommend this company to anyone! HMS will always be my number one company to call.

Michael G.

Responded quickly and did a small, easy job at a reasonable price when I got the run-around and outrageous estimates from other plumbing companies. This is to say, they did a job for about 200 that roto rooter estimated over 1200.00. Will use again when needed and suggest you do as well.

Ruth H.

Came out the same day and service tech was very nice and explained everything he was doing. Quick service and would use this company again.

Billy J.

I had HMS out for a system not cooling. They showed up when they said they would and had the house cool again in no time. Courteous workers and fair prices.

Martin D.

Had another local group troubleshoot air conditioning and they said a full replacement system ($8000) was needed. Called HMS for second estimate and they isolated the issue and repaired for $92. We have been using them ever since for nearly three years now. Always prompt, always thorough, always polite, and always a reasonable and fair price. Nathan is the best!
