TESTIMONIALS

What Our Clients Say

Brandon, the technician, was excellent—he explained my unit clearly and was very polite. The only issues I experienced were some misinformation about my account and the lack of communication regarding the appointment. I was told someone would reach out the night before with my time slot, but that never happened. I had to call in myself to confirm that someone would be coming out few times on the day of appointment.

Technician was on time and explained clearly how our system worked and the maintenance done and what we should expect maintenance and repair to cost in the future.
Maxime Caron
At the first preliminary service call to evaluate and diagnose our system in a commercial space with heating and a/c the tech discovered a filter that had been lodged inside the system where it shouldn’t have been. It had been there since the system was installed! 15 years. Even with an other company servicing the system. Removing it freed up the airflow and solved one of the issues. A comprehensive list of near future and further out repairs was written up with ballpark pricing. Personable tech and admin staff. Excellent work! Looking forward to seeing a Preventative Maintenance Agreement with Cardinal.

Christopher Roberts
Kenneth came first thing in the morning to service the furnace and heat pump. He was professional, courteous, and very knowledgeable. He performed the work in an efficient timeframe and did an entire overview of what might be needed in the future. He gave me information on other offerings Cardinal heating has without the major sales pitch, which I appreciated and may take advantage of in the future. 100% satisfied today. Great work Kenneth.
