Your service rep took care of everything!

On my first call under a regular maintenance contract, your service rep Dan noticed that the gas pressure was way below what it should have been. Before I even knew about the problem, he had already arranged for the builder to contact me to replace the outside gas regulator, all under warranty, free, and completed in two days! Thanks, Dan, for the fantastic service! The furnace, range top and fireplace all work a lot better now.

Excellent service and follow through

I was highly impressed with the service and follow through of Christie, the service techs,up to and including the Operations Manager, Scott Johnson. My furnace quit working and presented a challenge to get it repaired. The above people stayed with me until the problem was resolved. I HIGHLY recommend this company for their integrity in service and installation. This company is a rare jewel in today’s market place.

Pleased with the ethics the company stands by.

I went after three quotes for the replacement of my A/C unit. Sales Rep was very professional. They came in mid rang on pricing but was pleased with the ethics the company stands by. Install team was courteous and respectful of property, again very professional. Will hire them again when the furnace goes out.
Thanks guys!

I am writing to tell you what a great representative for your company David Harmsen is. He has been to the house three times; he is very professional and given us outstanding customer service. Thank you.

Dan Boom serviced my furnace yesterday and I wanted to write a note to compliment the extremely high level of service. Dan did a great job and helped me learn more about my system and how to use and maintain it, as well as some potential upgrades that might improve my system. I will definitely use Smith & Willis for future service as a result of the great experience of Dan’s service. You are lucky to have such a great employee.

Smith and Willis has the warranty contract on our air/furnace and I couldn’t be happier with them. Always friendly, helpful and quick to accommodate. Chuck has been to our house on both our air conditioner and furnace and is fantastic. We will definitely continue with them after the warranty.

Mondo is very well put together, communicated well, is very knowledgeable and helpful. I had a squeak in my floor and I was told there was nothing that could be done about it. After going around in circles with other subcontractors, Mondo came and was able to fix the problem. I am very impressed and wanted to let you know.
