Coomes was very good at keeping me updated prior to my service call. They notified me about the change and technician servicing my unit and why the change occurred. The technician arrived on time and was very courteous. He explained every thing that was done clearly and made sure I understood. This company has been servicing our HVAC system since 2018. They have been the gold standard in efficiency and customer service. I recommend them to my friends and neighbors.
