Furnace Repair in Parker

At about 5,800 to 5,900 feet, furnace input has to be reduced about 4 percent per 1,000 feet above sea level, along with a high-altitude pressure switch above 4,000 feet. That is close to a 23 percent derate. A furnace that was installed without the conversion overfires, which can overheat and crack the heat exchanger and produce carbon monoxide. Since furnaces run longest on the coldest mornings, that is when these problems tend to show up.

That is why every furnace visit includes a carbon monoxide check and a combustion safety test before we touch anything else.

After the safety checks, we pull fault codes, measure gas pressure and temperature rise, test the igniter, flame sensor, limits and pressure switch, and inspect the blower, filter, venting and condensate system. Our trucks carry the common failure parts for Trane, Lennox, Carrier, Goodman, Bryant and Rheem furnaces. You approve a flat-rate price before work starts, the diagnostic is free with the repair, and overnight and weekend calls are billed at the same rates.

Inside town limits, the Town of Parker Building Division handles permits and enforces the adopted mechanical code. It schedules inspections requested before 4 p.m. for the next business day. Stonegate and The Pinery have Parker mailing addresses but are unincorporated, so a furnace replacement there goes through the Douglas County Building Division. We confirm which applies before ordering equipment.

Natural gas in town is supplied by Xcel Energy, even though electricity usually comes from CORE Electric Cooperative. Xcel's recent Colorado rebate summaries have offered furnace rebates for 95 percent AFUE or higher units that replace non-condensing furnaces, which can help offset the cost of retiring an older 80 percent unit. Program details change annually, so we verify them with you.

We generally recommend repair when the heat exchanger is sound and the fix is a single component. Replacement is worth discussing for 20-year-old 80 percent furnaces facing a major part, or any furnace with a cracked heat exchanger.
