We are your Local HVAC experts!

Jonas offers a wide variety of Energy-Efficient Heating and Cooling systems. Read a little bit more about what we have to offer below...

Air Conditioning

Cool your home or business more efficiently this summer! We offer a wide variety of solutions for every cooling need. We are the area's premier Mini-Split A/C system providers. We earned the Mitsubishi Diamond Dealer Award three years in a row, and have been named as a leader in residential sales! We've also earned the American Standard dealer of the year award. You can trust our expertise to bring you a system that works and won't let you down when it gets hot. We service all makes and models, and we sell equipment from industry leaders such as Mitsubishi and Amercian Standard.
Don't forget, a properly engineered AC system will save you money and provide you comfort for many years. When you shop for a new AC system, make sure you purchase from a contractor that will stand behind your system. Not all AC systems are created equal!

Heating

No one offers as many different options as we do! We've been providing efficient, comfortable heating systems for over 30 years. We sell, service, and install radiant, hydronic, gas/oil/electric furnaces, heat-pump, decorative, passive-solar, and more. We can recommend the right system for your home or business.
There are many variables that can affect the performance and reliability of your heating system. Our experts will be able to help you find a system that fits your needs.

Indoor Air Quality

You would be amazed at the number of alergens and contaminants that can make their way into your home. Do you suffer from allergies or other respiratory issues? Maybe it's time to have our experts evaluate your indoor-air-quality. We employ a variety of methods that can greatly enhance the purity of the air inside your home, as well as enhance your quality of life.
Don't suffer unneccessarily, we can help you live a better life, and breathe easier!

Efficient Water Heating

Water heating can make up a large portion of your utility bills. That's why it's important to size and engineer your water heating system properly. Our experts will help you select the right system for your home or business so that you will have all the hot water you need for an affordable price. We sell tank, tankless, and boiler/hyrdronic systems too.
We can help you select the right system for your budget. Call us today!
