W Castro Aurora
in the last week
My husband and I needed a new air conditioner and water heater. We had no knowledge of what was needed or what manufacturer was the best. Signature responded to my Internet query for our needs. I was so impressed with the sales personnel, as they worked to acomplish what we needed within our limited budget. They were all extremely welcoming and professional. The installers were also very knowledgeable and helped with any questions that I had with respect to our new equipment. The sales personnel were honest and forthright in helping us choose our air conditioner and water heater. They took the time to explain the pros and cons of each manufacturer and made sure that we did not purchase an air conditioner that was 'more' than we needed for our home. We thought that we needed a new furnace too, and they took the time to examine the furnace and notified us that we did not need a new one at all. The company representatives could have easily installed a new furnace and charged us whatever fees would have been involved, but instead, they were honorable in telling us that we did not need a new furnace. If we need ANY work in the future, Signature will be the one and only company that we will call for assistance, It is so nice to know that there is at least one company left in the world that is more concerned about the customer than they are about the 'dollar'. We would highly recommend this company to anyone that needs this type of service. • • •

" I want to take this opportunity to thank you for the superior customer service I received from Signature Heat & Air.  All of you were a delight to work with, and I was especially appreciative that you took the time, as the owner, to come out and inspect the job before considering it complete.  I've never experienced this level of service from a contractor before, and think it reflects your commitment to quality and customer satisfaction!

I will definitely recommend your services to everyone I know looking to replace their furnace or A/C unit."

Thanks again,


"I just need to tell you, Steve & John, that I was very impressed by the quality, price, and professionalism of the service you two provided in servicing my A/C system.  I would definitely place your service at the top of the list of all HVAC service providers I have used!  Thank you very much for everything!

I will definitely recommend Signature to others.

"Steve has never missed an opportunity to help me over the phone and the service they did in my home was second to none!!!  I wouldn't use any other service for my heating needs (I don't have an air conditioner), even if a friend referred me elsewhere, because I DON'T NEED TO call anyone else!  Signature is THE BEST in my book!  If you have any heater or air conditioner issues, I strongly suggest you call Signature and consider it taken care of!   Wendi - Northglen

    Thank you so much for eveything you've done for us, Signature!
