I built my home thirteen years ago and stayed with the same contractors for years, but I had trouble establishing communication and services with the third owner. Around the time I started searching around for a new service, my son hired Comfort Shield Heating and Air Conditioning, LLC. to install a full system in his home. Since my son works during the day, I went to monitor the installation for him and I was very pleased with what I saw. I have since contracted with the company for my biannual maintenance beginning this year. The staff are very reliable, communicative, and informative about your system. They have honored warranties for systems they did not install and are in contact with the manufacturers so I do not have to be myself. Comfort Shield Heating and Air Conditioning, LLC is a reputable company with fair pricing and I highly recommend the services the company offers.
