Gas Furnaces

Furnace service.

From skiing the fresh powder at Mt. Bachelor to snowmobiling the open trails at Deschutes National Forest, Central Oregon comes alive in the winter.

We embrace the cold, soak in the sun, and enjoy our scenic landscapes. But at night, as the skies clear and the temperatures dive, we turn up our furnaces and bask in the glowing warmth.

When the time comes to replace your older furnace with a newer model, you can count on Diversified Heating & Cooling to find the perfect home heating system for your budget and lifestyle. Our team of professionals will calculate the square footage of your Oregon home and how well each room is insulated to determine the right-size furnace for your needs.

What You Need to Know About Gas Furnaces

Most furnaces in Sunriver, OR, run on natural gas because it is widely available and tends to be the most economical choice. A properly maintained gas furnace should operate for 15 to 30 years before you need to replace it.

You will want to know the annual fuel utilization efficiency (AFUE) rating of your furnace. An energy-efficient furnace will have an AFUE rating of 95 percent or higher, meaning it can convert 95 percent of the energy it consumes into heat.

The higher the AFUE rating, the more money you save on monthly utility bills. Energy-efficient furnaces also help the environment since they emit a lesser amount of greenhouse gases into the atmosphere. Keep in mind that maintaining your ductwork and sealing the windows and doors in your home are key factors in energy-efficiency savings. If your home is poorly insulated, your furnace will struggle.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient unit. You can even customize it to better match your home's system for a more accurate calculation.

“We're so glad we contracted with Diversified to replace our old, broken, un-repairable heater. Jess and Catie were great with regular communications and answering all our questions. Travis and Raul showed up right on time and went right to work. A few hours later and we were good to go with heat warming our house FAR more efficiently than what we've been experiencing. We'll happily recommend Diversified to anyone looking for a great company to work with on their heating/cooling needs.”

“When I was in my garage I heard water. It was coming from my furnace. I decided not to contact the heating and cooling company that did the maintenance on it because they did a terrible job on something else. David from Diversified immediately knew what the problem was, he showed me what happened, he explained very clearly how it happened and then he clearly explained how to fix the problem. I appreciate his attention to detail and his simple explanations. The other heating and cooling company lacked the attention to detail and that created the problem. David treated me with respect and he took great care to resolve the issue. As a result, I will move forward with Diversified as my go to heating and cooling company.”

“On 12/28/23 I called into Diversified at 4:00 PM, we had no heat from our furnace (just cold recirculating air), I didn't expect to have a tech dispatched that evening, they put me on hold for just a minute and told me they would have a tech over in an hour, great!! Sunshine called and texted that she was on her way, she was exceptional, professional, organized and efficient, best service tech by far.

Thanks Diversified and Sunshine!”
