I had Heatmaster Services quote and install a humidifer and air conditioning system in my home. Dmitri was able to provide the lowest quote, complete with a detailed breakdown of costs so that I could see where my money was being spent. You have to respect a company that is able to provide this sort of transparency and detail, then stay true to their word at the end of the job. He knew a lot about my older furnace system and was able to custom fit the right AC unit for my home. I knew I could trust his advise as he was able to point out minor problems in my existing heating system and fix them for free to stay true to his quote. The job was done on time and clean up was spotless. Every step of the install was explained in detail showing he is very knowledgable in his trade. I would recommend Heatmaster Services for any residential heating and cooling needs. Bring on the summer heat, I'm ready. Thanks again guys.
