Business overview

Charles Marker - In House Services is a growing family owned and operated business in Southwestern Ohio, serving Ohio, Kentucky and Indiana. Our focus is Preventive Maintenance for Air Conditioning and Refrigeration to help avoid unexpected, high cost repairs. We also service and repair air conditioning and refrigeration systems and offer affordable service plans.

After retiring I wanted to have a new career that would not only help pay the bills but allow time for family and allow.. us to help others at the same time. We can?t help others by breaking their banks.

We are local, we are mobile and we come to you for automotive and appliance refrigerant recovery and recharging. We are E.P.A. and ASE certified.

With the high cost to operate air conditioning and refrigeration systems, whether in your home, business or automobile it is crucial all components run at peak performance and are maintained properly to increase their dependability and life span. Properly maintained systems save energy, reduces repair and replacement cost, and saves on utility and fuel cost.

RESIDENTIAL: For residential customers we walk through the homeowners cooling system components with them showing them what everything is, what condition it is in and what they can do to keep their system running more efficiently, longer. We offer Preventive Maintenance and Annual Tune-Ups, as well as services for replacement of compressors, evaporators, blower motors, condenser fans, etc. if required.

BUSINESS: For business customers we offer the same tips on preventive maintenance and the same repair services as we do our residential customers. We provide not only preventive maintenance, annual tune-ups and services for replacement of compressors, evaporators, blower motors, condenser fans, etc., but repair services for the following units:

Ice Machines
Sandwich units
Reach-in and Walk-in refrigerators and freezers
Pie cases
Roof Top Units (RTU) air conditioning
General Maintenance Services for your business

AUTOMOTIVE: Automotive services include recharging of air conditioning in any type of vehicle. If necessary we can recover your refrigerant, do leak detection, then recharge your system with the proper amount of refrigerant after repairing the minor leak. If necessary, we can advise you as to the type of work that may be required so you can take your vehicle to a certified mechanic for more in depth repairs. 9 times out of 10 problems are simple, but that number 10 needs the right person for the right job.

We would like to invite you to visit our website to see who we are and what we offer.
