Synergy has the tools, people, and the products to provide an indoor weather system that fits your lifestyle and budget.

We believe in what we do, and to be your HVAC contractor of choice. Let us show you how Synergy can surpass your expectations in service and performance. You can count on us for custom-made indoor weather now, and for many years to come.

Weigh the Cost to what you get.

Remember you are not just buying a Furnace, you are buying into the business you are working with. Furnaces are complicated systems and requires a lot of field and factory training. A proper installation is 90% of the experience. You could purchase the best Furnace, have it installed by an untrained crew and before you know it your expensive investment either has an un-wanted repair or needs to be replaced and you could be the one paying for it. Take note of everything you get from a business and never assume the second business is going to do what the first one does. Everyone is different, be sure to get all promises in writing.

Synergy Geothermal-Heating-Cooling can:

  • Design a HVAC system to meet your needs
  • Service all makes and models
  • Provide a cost-effective process from beginning to end
  • Offer final products that exceed expectations

We not only focus on providing quality HVAC products, installation, and service, but also on having the best educated sales and service staff to make sure that you, the customer, is well informed about the decisions you are making. Putting the needs of the customer first isn’t just another marketing tag line to us, it’s the way we do business.
