Furnace Service

Proper furnace venting is a critical safety element that deserves careful attention during any furnace installation or replacement. Standard 80 percent AFUE furnaces vent hot combustion gases through metal flue pipes to the outside of the building, relying on the natural buoyancy of hot gases to draw them upward and out. High efficiency condensing furnaces vent cooler exhaust gases through PVC pipe, typically through a sidewall rather than through the roof. Matching the venting system to the furnace type is not optional; using the wrong vent materials or configuration creates a safety hazard. When replacing a furnace, the existing venting often needs to be evaluated and possibly modified to suit the replacement equipment. DC Electrical HVAC Plumbing addresses venting as an integral part of every furnace installation, not an afterthought. We also check existing shared flue systems in homes where the furnace and water heater share a common vent to confirm the flue is properly sized for the remaining appliance after a high efficiency furnace is installed. Getting the venting right is a fundamental safety requirement, and it is one area where DC Electrical HVAC Plumbing never cuts corners.

The heat exchanger is the most critical safety component in a gas furnace. It is a metal chamber that separates the combustion gases from the circulating air, allowing the air to be heated without coming into contact with carbon monoxide or other combustion byproducts. Over time, repeated heating and cooling cycles cause the metal to expand and contract, which can eventually lead to cracking. A cracked heat exchanger is a serious safety hazard; combustion gases that breach the exchanger can enter the air stream and circulate through the home, creating a carbon monoxide risk. Signs of a cracked heat exchanger include a visible crack in the metal, soot buildup near joints, a yellow or flickering burner flame, or a carbon monoxide detector alarm. DC Electrical HVAC Plumbing inspects heat exchangers as part of every furnace maintenance visit and during any service call where a safety concern is suspected. If a cracked heat exchanger is found, we shut down the furnace and explain the situation clearly, including the cost of replacement and the option to replace the furnace if the system age makes repair uneconomical. Safety comes first on every furnace call, without exception.

Furnace efficiency directly affects the monthly cost of heating your Lawrence home, and the difference between equipment ratings compounds significantly over the lifetime of the system. A furnace with an 80 percent AFUE rating loses 20 percent of the energy in every unit of fuel through the flue, while a 96 percent AFUE model loses only 4 percent. In a home that spends $1,500 per year on gas heating, upgrading from 80 to 96 percent AFUE reduces that cost by roughly $250 annually. Over 15 to 20 years of operation, those savings add up to several thousand dollars, which can offset a significant portion of the cost difference between the two equipment tiers. The calculation becomes even more compelling when replacing an older furnace that may be operating at an actual efficiency well below its original rating due to years of wear and component degradation. DC Electrical HVAC Plumbing helps customers in Lawrence evaluate the long term economics of different equipment options, factoring in upfront cost, estimated energy savings, and available rebates or tax credits. Utility rebates for high efficiency furnace installation are sometimes available through Evergy or other Kansas energy programs, further improving the return on investment. Our team stays current on available incentives and can advise you on programs that apply to your installation.

Thermostat compatibility is an important consideration in any furnace installation or replacement. Modern furnaces with variable speed blowers and two stage burners require thermostats that can communicate with and take full advantage of those features. Installing a basic single stage thermostat on a two stage furnace limits the system to single stage operation, eliminating the efficiency and comfort benefits the equipment was designed to provide. Smart thermostats add scheduling, remote control via smartphone, and learning algorithms that further optimize furnace operation and reduce energy consumption. DC Electrical HVAC Plumbing evaluates thermostat compatibility as part of every furnace installation and recommends upgrades when the existing thermostat would limit the performance of the new equipment. We install and program thermostats as part of the installation process, so the system is set up correctly and you know how to use all of its features before we leave. A properly configured thermostat is one of the easiest ways to maximize the comfort and efficiency of a new furnace installation. Customers who combine a high efficiency furnace with a compatible smart thermostat consistently report excellent comfort and noticeable reductions in their monthly heating costs.
