I highly recommend Semper Fi Heating and Cooling, they helped me fast without cutting corners. Best of all I was offered a great price for a much needed New A/C. They installed better than the original builder, I was impressed. For a good deal & great work ethic company who cares, give them a call you will be glad you did.

Overall I think the service I received was good. I do feel their prices were on the high end $3,500 especially since I purchased two HVAC’ from them in the past three years and had the vents cleaned and ultra violet lights installed which costed over 25k. I will have to repaint and I just painted the area in June. I do think that moving forward I will have to get multiple quotes before selecting a company even if it is a hot water heater or HVAC
