I again wanted to mention what a great job your guys did and what a pleasure it was to have them at my house.  They all worked so well together and are all a credit to your company.  They all knew what they were doing and got it done. 


While I felt a bit guilty having the guys out on a Sunday, it is great to know your company is available seven days a week.

You folks are terrific to deal with and i have recommended Cote's Mechanical to a number of people. You have great customer service and we are very pleased we have chosen to do business with you. as an aside when the town inspector came out after the the installation was completed he commented on what a "top grade installation"  (his words) your team had done.  I would rate Cote's Mechanical 5 stars.

“Foster and Cote, How can we begin to THANK YOU and your staff for your services today. We truly appreciate how you handled our urgent situation. I hope the family buying our home will enjoy the cool, energy efficient comfort the new unit will provide. Jonathan and Tom were awesome! Jonathan took the time to explain the problem, recommend the solutions and both were very efficient with the repairs You have two great employees! Foster, it was a pleasure to meet you and we appreciate the cost efficient proposal you provided. You have our business for years to come and I will highly recommend your company to anyone needing heating or AC repairs. Thank you ALL once again.”

“Thanks for getting our air fixed! My boys called and said it was so much better! I really do appreciate you! It will be great to go home to a cold house instead of a muggy one! Have a great day!”

— Kenna K.

“Greetings! I can't thank you enough. I sent in a service request before dawn and James was here to get my a/c running in no time. Even with a trip to Denton for parts, he had the work done and my house beginning to cool by 10:30! In an era when the sloppiest folks and poorest work are called “customer service,” it was a true joy to me to have this awesome experience. I never got to the danger point with breathing difficulty, and James was pleasant and obviously competent. Anyone I know looking for HVAC work will definitely get a recommendation to you folks from me, a Very Satisfied Customer!! Thank you, and blessings to you all.”

“Just wanted to let you know what a great job your guys did yesterday on the system…very hard workers and very efficient…couldn't have been happier with them. If they do all their jobs like this they will keep you in business a long time. Thanks.”

— Tom T.

“Cote's Mechanical gave us several options for our new system and explained the benefits of each. They arranged financing with very good terms, and had a crew out immediately once we made our decision. Everyone was very professional and courteous. They replaced our entire AC/heat pump system in one day. There was no “hard sell”, they did everything they said they would do when they said they would do it, they installed high–quality equipment at a good price, they worked with the home warranty company to maximize their contribution, and they were great to work with. Our new system works great – we are WAY more comfortable – and we are looking forward to lower electricity bills. This is an excellent investment in our home. Thanks to Foster, Cote, and everyone at Cote's Mechanical!”

— Dev H., Lewisville, Texas
