I needed service on a furnace that we have had in our house in Del Mar for almost 18 years. It was working fine until December but then one day it had a funny smell and then no longer worked. I found Carini Heating and Air Conditioning on YELP and saw they had good ratings. I also read reviews about them and had their service man come to check the system. The man, Anthony, took a lot of time an explained that a newer furnace could save on energy use and the warranty was good (it was a Rheem heater). I have been very happy with the performance since it was installed. Good work by the company.
