"I highly recommend Top Energy Solutions. During the heat wave my air conditioning system blew out hot air. I expected to wait days for a technician to come out. Leor sent one the next morning. The technician quickly located the problem and fixed it within minutes. Their employees are professional, courteous and very knowledgeable."

"Heard about them through Angie. They have a professional and comprehensive set up. Their dispatch provided updates on when the technician would arrive. Even provided me with photo and brief work history of the HVAC technician. Phil, diagnosed and performed maintenance on my unit. He was very patient and waited until my work meeting ended. I’m very pleased with their professional service."

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."
