Thank you for visiting our company website.
My name is David Johnston and I am the proud owner of Combined Services HVAC. I have had the opportunity to work in the HVAC industry for over 30 years. In 2009, I decided to open my own company with a few of the most experienced and talented people that I have known in the industry. We use our collective experience to provide our clients with quality products at a completive price. Since the beginning, Combined Services has focused primarily on the Residential HVAC business. From heating and cooling a multi-million dollar home to a small condo, we have been providing the very best engineered systems around.
Since 2009 we have grown into the HVAC Company that can tackle any project. Whether it is residential, commercial or industrial we are the only HVAC Company you will need. If you are looking for service, system replacement or a complete home duct system, we are the experts for you. I will work hard to earn your trust and business. I look forward to working with you.
