Professional-Quality Heating Installation Service, Done Right Every Time

You should be leery of any HVAC contractor who will install a new heating system without re-evaluating your home to ensure it’s sized right.

There are a number of changes to your home, such as new windows, renovations to the original structure, or additional insulation that can affect your home’s heating requirements. A costly mistake we see all-too-frequently is the installation of an oversize heater. Target temperatures are reached too quickly and components can’t reach peak efficiency levels. Short, frequent cycles of an oversized system can result in a shortened system life, wild temperature fluctuations, system deterioration, and higher operational costs. In short, oversized equipment is definitely not an advantage.

Our highly-trained and experienced HVAC installation technicians will ensure they specify the perfect size for your new furnace. Our extensive hands-on experience, in-depth manufacturer and industry training, and state-of-the-art diagnostic equipment and tools are part of every job. We will custom design the ideal heating system to deliver maximum energy efficiency, along with evenly-distributed warmth, and highly dependable operation at a lower cost for the life of the furnace.

As a Rheem Pro Partner, our certified heating installation technicians receive ongoing in-house and manufacturer training. We consider our team uniquely qualified to recommend and execute leading-edge heating technology. Dor-Mar Heating & Air Conditioning is proud to install and service quality Rheem and Coleman products, two of the most respected names in the HVAC industry.

When you invest your hard-earned money in a Rheem heating or cooling product, you can expect more than just run-of-the-mill temperature control. These amazing, built-to-last heating systems are designed to automatically adapt speeds to deliver maximum efficiency and optimum temperatures.

In addition, WiFi capabilities on some of our leading-edge thermostats allow you to change settings on the fly, track energy use, and receive notifications virtually anywhere you have a cellular signal or a WiFi connection. We consider Rheem to be more of a superior way of living instead of just improved temperature control.
