I do not know much about heating/cooling or even how to chose a service company. I used ABC once through a recommendation when doing a final walk through during the purchase of my first home. The A/C wasn't working and ABC came right out. 4 years later it was time to service my A/C again (just an old unit, nothing to do with their previous service) so I called them again and luckily they were able to come out same day. Great service, friendly technitian. I'd recommend ABC to everyone!
