What Our Clients Say About Our Heating and AC Maintenance and Installation Service

The Real McCoy did a great job specifying and installing the Heating and Air Conditioning systems at our new Tasting Room Building.....their workmanship was excellent and they came in on time and under budget. Also their after sales service and follow up has been very good.  Based on our experience, we would definitely use them again on another project.

We had two different service men from two different local companies out to check the motor in our heater.  Neither one could find out what was wrong, but both charged us for a ‘service call’.  I called Seth McCoy at The Real McCoy.  The heater made a loud noise when it was on.  Seth said he knew what was wrong but explained that it was difficult to find parts for our mobile home heater.  He took out the heater motor, took it with him to his parts supplier and was able to put the parts together that took care of the problem.

Since it was so cold in the ‘big snow’ of 2010-2011, we were very grateful to Seth.  He had the motor back in the same afternoon and it has been working fine every since.   His prices are more than fair but what impressed us the most was how he insisted on making sure everything was working properly.  He is genuinely interested in doing the best job possible.

Now that is what I call service!
