Furlong HVAC is very responsive. We called them initially to fix our AC unit, which was quite old. In the end, a new unit was needed and they reduced new unit price, by the amount I paid on the initial service call. All in all, I would highly recommend this company. Curtis was very polite and explained everything to us very well.

Outstanding experience all around. Phone was answered by a real person who was pleasant and professional. Appointment was made promptly and we were called when Curtis the service technician was on his way. Curtis was on time and stayed until the job was completed perfectly. We will definitely use them in the future!! Thank you!
