PA Reviews

“Installers came today on-time and immediately went to work installing my new heating and air conditioning system. Chris, the team leader,explained what he was doing and was very friendly and knowledgeable. The team worked well together and I am very satisfied with the professionalism and work ethic. They did a terrific job and I will certainly recommend McCrea. They deserve a five-star rating.” – Google reviewer, May 2020

“We have been McCrea customers for many years.  Whether it is an emergency … of which there have been few because of the excellent maintenance service … or it is the bi-annual check on the HVAC system, the service has always been easy to schedule, prompt, professional and courteous.  Our last maintenance call was covered by the team of  Burt and Brooks.  They were excellent.  Ours is a 2 zone house and the systems are of somewhat different age and need different attention.  The team was very good at helping us understand the different maintenance requirements and what follow up they would recommend to keep the older unit functioning at high efficiency as long as possible.  We would recommend this team and the entire McCrea enterprise with enthusiasm and without reservation.” – Yelp review, 2018
