About the Owner
Meet Fred Holder

Cool Masters owner Fred Holder was born and raised in York County and is proud to provide quality service throughout the region. Fred began working in the construction field during the early 1980’s when he started out as a roofer while also doing a lot of masonry work. From there, he worked for a construction company that pretty much did it all. In the process, Fred started doing plumbing and electrical work along with heating installation and air conditioning repair.
That kind of on-the job training prompted Fred to take some courses related to his field at Penn State and some other local schools. Those courses helped give him an even broader knowledge of the building process. Fred narrowed down his favorite part of the business to the heating and cooling aspect. Then, in 1996, Cool Masters was introduced to York County after years of education and training.
Continuing education is part of the job
Fred’s continuing education helped him acquire multiple certifications related to the repair and installation field. His friendly demeanor has also helped form a tight-knit organization with trustworthy employees. Every one of the technicians at Cool Masters is required to pass a thorough screening test. That includes drug testing as well as criminal background checks.
Cool Masters has become a staple of the York community and a business that residents can trust. Cool Masters provides service to York County area with its shop located Mt. Wolf. Its experienced team of technicians also provides repair and installation services in Lancaster PA, Gettsyburg PA and other surrounding areas.

Testimonials
“I appreciate your promptness..”
“Just wanted to drop you a note and let you know how much my husband and I appreciated your promptness when our central air conditioning died. You were prompt in answering my call and sending someone out the same day. The price was very reasonable and your work superb. You were understanding and worked with us on the payment. So again thank you so much.”
Mrs Paula J – York PA (Hayshire Area)
“Prompt, Professional…Pricing Was Above All, Fair. “
“We have had Cool Masters to our home twice in the last three years. Each time you were prompt, professional and your pricing was above all, fair. What a rarity your company is in today’s world.”
From Cindy M. – Stewartsown PA
“Professional and A Super Job Cleaning Up”
“My wife and I were both impressed with your two installation representatives, Bob & Brandon. They were professional and did a super job cleaning up both inside and out after finishing the job. You did a terrific job explaining the features and benefits of the Trane product. Thank you also for the extra visit to clarify the positioning of the A/C unit outside. I think the spot we picked works well. The unit blends in nicely with out landscaping, despite the large size. Your pricing was competitive and fair and in combination with the outstanding service, I would fee comfortable recommending you and your company to any of my neighbors.”
From Jim G – Outdoor Country Club Development – York Pa
“You Were A Pleasure To Work With..”
“I wanted to drop you a letter to say that I am very pleased with the Trane furnace and air conditioning unit recently installed in my condo. You were a pleasure to work with providing a prompt quote on the job and answering any questions and concerns I had. The installers were both very courteous and professional and hard working throughout the two day installation. Leaving the job site after the first day, the installation site was left clean and clear of any debris. When the Springettsbury Township inspector came out to approve the work, he commented what a quality and professional job had been done. I would highly recommend Coolmasters to any client needing service or replacement of their heating and/or air conditioning. Sincerely yours.”
