Cardinal has been servicing our system for the last five years. Sarah has done a great job of keeping our 30+ year old gas heating system and 20+ year old AC system operating as well as keeping us informed of what to expect in the future. Thanks, Cardinal.

We moved to having Cardinal Heating and Air service our radiant boiler system after to many problems and mistakes and outrageous bills with the original installer. Cardinal Heating and Air did a great job fixing the problems with the original system and when that boiler finally failed during the coldest part of winter, Cardinal Heating and Air was able to clearly explain everything that was done wrong in that first installation and put in a replacement system that addressed those problems. We have relied on them for annual maintenance for each of the two years since that installation and continue to be completely satisfied. Their pricing has been competitive, their work is professional and clean, and every employee of Cardinal Heating and Air that we have interacted with has been courteous, informative and transparent with everything. I highly recommend - don’t hesitate to give them a call!

Excellent, efficient service from friendly technicians.

We were very pleased with Cardinal's prompt response and quality of work. More than anything else they demonstrated a high level of transparency and trustworthiness. The prior company I worked with tried to sell me a new $30,000 system just because out unit had a dirty coil and was 12 years old. Our Cardinal technician confirmed that out equipment still likely had a number of years left on it, and only a minor bit of maintenance to replace a $50 part (which the prior company didn't do). Cardinal is now our go-to HVAC service provider.

Great service, on time, knowledgeable techs
