Heating Installation

You may have inherited your first heater when you bought your house. Installing a new heating system is an important decision and deserves careful consideration. The technicians from Donovan Heat & Air have the insight, experience, and product-familiarity to help you make the best choice for your specific needs and heating dollar. If you are looking for top-of-the-line comfort, dependable performance and superior efficiency, we install only those manufacturers and models with unprecedented temperature control, economy, and proven reliability.

PRO TIP: New furnaces offer improved efficiency

A gas furnace, manufactured forty years ago, typically offers around 65% AFUE. The lowest efficiency now permitted by law is 78%, and many options boast up to 98% AFUE, which is near total efficiency. More efficient furnaces not only cost you less to operate, they generate fewer emissions. Since your cost of heating tends to rise in proportion with your furnace’s fuel efficiency, you can expect to recoup money through lower fuel bills over the life of the system.


The specifications of your furnace should fit your needs. Most homes have furnaces that are larger than needed, which not only costs more to purchase, but keeps it cycling on and off. This frequency puts more wear on components, wastes energy and can cause temperature fluctuations. Too small of a furnace won’t keep your house comfortable during the coldest nights of winter. We’ll inspect hot and cold spots, insulation levels, ductwork, number of windows and take a look at unconditioned spaces, such as attics, garages and crawl spaces to calculate your heating requirements.

Selecting a qualified, licensed contractor to install your new heating system is the most important factor in how well it will work, how long it will last and how much it will cost you over time.
