We live in a Barranca Mesa Los Alamos home built in the 1960's with baseboard heat and a boiler but no air conditioning.. Pro-Tech installed mini-split Carrier HVAC units throughout our home in the spring of 2019. Steve came out and did our home assessment and recommended mini-split units instead of central air conditioning and was an excellent sales person contact. Installation was very professionally done with minimal disruption to home and great cosmetic result. Units have worked great for both additional heating for individual rooms this spring and cooling this summer. Highly recommend working with Pro-Tech to meet your heating and cooling needs.
