Testimonials From Our Valued Customers


“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.”

From Mrs Paula J – York PA (Hayshire Area)



“Your Promptness Was More Than I Expected”

“You have no idea how much I appreciate what you have done to correct my A/C problem. Seriously Fred you have helped us financially and your promptness was more than I expected. May God richly bless you.

Respectfully yours.”

From Mr & Mrs Beaver – York 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



“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



“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.”

From Denise C. – East York, PA



“…Best Purchase I Made For My House”

“My girlfriend and I are enjoying the air conditioning. This was by far the best purchase I made for my house.

Thank you for your service.”

From Don S. – York, PA



“Courteous….Everything Was Clear…”

“This letter is in appreciation for installing the air conditioner on a Saturday, during one of the busiest times of the year.

Bob and Brandon did a super job installing our furnace in such a small space. They were very courteous and explained how the new furnace operates. Everything was clear when they finished the job.

We will recommend your business to our friends. Gary says, thanks for installing the digital thermostat, he is now living in the 21st century.”

From Gary & Norma. – West York, PA



“An Outstanding Job…”

“I want to express my appreciation of how Bob and Brandon did such an outstanding job on our new Trace Central Air/Gas furnace installation last week.

They arrived promptly, when scheduled and performed in a professional manner with no disruption to our families home activities.

Very neat/cleanup after the job plus provided a thorough explanation of the systems operating features.

Both are outstanding technicians and a great credit to Cool Masters!!! Plus Fred, I appreciate your manner in working with us from the initial home visit, answering questions etc.

You may use me as a reference for Cool Masters anytime!!”

From Larry S – Dallastown, PA



“Thank You, Fred, For A Job Well Done.”

“On behalf of our council and congregation, we would like to take this opportunity to thank you for the courteous and professional manner with which you installed our new heating and cooling system.

When it became apparent that our 40 year old steam boiler system was failing, and with an increased desire among our members to have air conditioning, we knew it was time to have a new climate control system installed. However we had little idea of what systems were available, what would work well in our building, and what the cost for the project would be. Your insight and suggestions when we were trying to determine exactly which system would best suit our needs, and your willingness to answer questions and pursue information on our hehalf was of great benefit to us.

We would also like to compliment your workers on their professionalism. Throughout the course of the job, they were respectful and friendly to all who had contact with them and took great care in leaving us with a clean building every week in which to hold our services. They are an asset to your company.

We welcome you to use us as a reference and would be happy to accommodate any potential clients who wish to contact us or come to our church to see your craftsmanship.

Again, thank you, Fred, for a job well done.”

From The Trustees Committee – St Paul’s Lutheran Church – Spring Grove PA



“You Were Very Price Competitive….”

“You recently installed a new Bryant furnace in my house. In addition, back in 2003, you installed a new Bryant Deluxe Air Conditioning System in my home. Both heating and air conditioning units are functioning great. My wife and I are very impressed with your work.

You were very price competitive and completed the work on time. I found you and your staff very professional and knowledgeable. I would highly recommend your company. Thanks again for two jobs well done.”

From – Robert L – York PA



“I Am A Very Satisfied Customer.”

“Fred Holder was referred to me by my son-in-law Jerry Curran and installed a furnace and air conditioner for me. In turn three other condo members had furnaces installed.

Fred has a nice low key personality – no hard sell. He explains thoroughly. His workers always wore shoe covers to protect my floors. And when they need to work over my carpet they put down canvas drop clothes.

They too are very polite. I am a very satisfied customer.”
