     The Owner, Dathan Alexander, started in the HVAC field at the young age of 16, working in his family's Air Conditioning business in the Bay Area. They worked primarily on Hi-Tec commercial systems. In 2001 he moved to El Dorado County and worked with some of the best commercial companies as a Project Manager and Lead Service Tech. In 2010, he started working with Solar Power and energy efficiency evaluations. He realized there was a bigger need for highly technical systems that lowered power usage in order to save the customer money. So, in 2015 he received his Contractors license and started Alexander Heating & Air Conditioning.

     At Alexander Heating & Air Conditioning, we enjoy finding solutions for problems that others just push products at. We are building strong relationships with those in our community, by doing it "old school" meaning, we do not sell something that is not needed. We are a company where a handshake means something, and our yes means yes.

Heating & Air Conditioning

You know the phrase “ they don’t build’em like they use to”  well that applies to most Heating & Air Conditioning system's.

That’s right!

They are a lot better! Smarter!  And, More Efficient! 

If your system is more than 15 years old you may be wasting your hard-earned cash. Products have advanced so much in just the last decade, that the average system is wasting up to 40% of its energy consumption on heating or cooling.


So the best way to cut down your cost is to maintain and/or upgrade your biggest appliance, your Heating & Cooling System.
