Customer Testimonies

Dear Jeff,

On behalf of the Board of Directors, I would like to thank you for your generous act of kindness by getting the air conditioning unit up and running for us today here in the library. Doing this for us at no charge is a huge generosity. Scott was very courteous and respectful, and saw to the problem and took care of it. His announcement to me that you were donating this call was a huge relief, and I want you to understand how much we appreciate it.

Because we are a community library and not part of Shasta County Library system, we receive no federal, state or county funds to maintain our library. We have been successful merely due to the generosity and kindness of people and business partners like you here in the Shasta County area. We want you to know how much we appreciate and are grateful for the kindness you have shown us. It does not go unnoticed.

Thank you again for your kindness.

Dear Jeff,

Your dad and I have known each other and done business together for longer than 25 years and during this time Dennis’ Heating and Air Conditioning always provided excellent services and workmanship for our company. The attention to detail and arrival to scheduled appointments was without equal in your field of expertise. I know this is because your dad and his outstanding staff made it their priority to service each customer in an equitable and professional way. I will always be grateful for the business your dad and I did together.

Jeff, I am delighted to write, with pride, that since you have taken the “helm” of Dennis’ Heating and Air Conditioning, Inc. the same care and pride of work has continued flawlessly. I want to compliment you and your staff for outstanding work and service, day in and day out. Way to go! I am looking forward to continued business in the future…when the work picks up!!!!!!!!!!

In closing, I would like to express my gratitude for the way that your staff went above and beyond the call of “duty” to start up the heater at the “Fallow” job. Thank you so very much for your help. And as I have already alluded, it’s a delight to do business with your company.

Your firm installed the seventh air conditioner on my commercial building – Bartels Center – on Bechelli Lane. Each and every installation was done in a very professional, efficient, and timely manner. I was present each time with your crew and on every occasion I have been pleasantly impressed with their professionalism, courtesy, and work ethic. I usually see them doing something a “little extra” to improve their work and the installation and I appreciate their efforts.

I would happily recommend your company to anyone needing your service. Thanks for seven jobs well done.

Thank you for doing such wonderful work in installing our new heating / cooling system. I speak for my whole family when I say how happy we are with our system and your crew and their work. Hugo and his crew were neat, professional and very nice.

Thank you again, it is the best money we could ever spend.
