I was very, very impressed with Custom Heating. Not only did they call me within minutes of submitted my email request to Service Magic, they were prompt, professional and very good at what they did. I will always use them in the future.

Dwayne Haskins (the owner) oversaw all aspects of the project and answered all my questions thoroughly making me feel confident that the work would be done to my satisfaction. The A/C and Furnace are excellent and I have been very pleased overall with the job they did installing it.

The crew that removed my old water heater and installed my new tankless water heater were professional and minmized disruption throughout the entire process. I would recommend them to anyone.

While others seek to profit by cutting corners or recommending unnecessary services to customers, Custom believes that a good reputation and consistent service will reap bigger profits in the long run. 

Very happy with the job they did on a Prestige Boiler and side arm water heater installation. They were on time, always delivered what they promised. They negotiated the price to where i could live with it. Inspectors passed Custom Heatings work with out question.
