Waverly is a Highway 12 town with two lakes, Waverly and Little Waverly, where Hubert Humphrey built his lake home in 1958, and its population grew about 85% between 2010 and 2020.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Waverly and across Wright County. Every visit starts with a $79 trip charge and a written price before any work, and the $79 is waived when you go ahead with the repair.
Xcel lists Waverly for both gas and electric; rural properties outside town may be on a cooperative and propane.

Book in WaverlyWaverly began in 1856 as Waverly Mills, with a dam and mills at the outlet of Little Waverly Lake, and the railroad laid out Waverly Station around 1868. The oldest houses still sit near the lakes and the Highway 12 business blocks. The town then shrank for much of the 20th century, bottoming out at about 470 residents in 1980, so Waverly likely has fewer postwar ramblers than its neighbors and relatively little 1970s housing.
That changed after 2000. Waverly grew from about 730 residents in 2000 to 1,900 in 2020, so most homes are 2000s and 2010s two-stories, ramblers and split-entries with direct-vent 90%+ furnaces and, in the newer ones, an air exchanger. The 2000s homes are reaching the age of first major repairs, while the 2010s houses mostly need maintenance. Lots on Waverly Lake and Little Waverly Lake add a mix of older lake homes and newer builds.
Waverly's older in-town homes are where winter safety comes up. Many share one brick chimney between the furnace and water heater, and an oversized, cold masonry chimney left serving just a water heater after a furnace swap can draft poorly and collect condensation that crumbles the liner over a winter. A backdrafting appliance spills exhaust into the basement. Minnesota law requires a working CO alarm within 10 feet of every sleeping room, so test yours before the heating season. In the newer homes, keep the PVC intake and exhaust clear of drifting snow.
The newer Waverly homes are tight, and in July that means the air exchanger and the AC work together. A neglected HRV or ERV with a clogged core brings in less fresh air, and one running hard on a muggy day pulls in moisture the air conditioner then has to remove. Clean the cores and filters in spring and set the exchanger to intermittent or low in humid weather. On the lakes, houses near the water run more humid still, and an oversized condenser leaves them feeling clammy.
Xcel Energy supplies both gas and electricity in Waverly. Xcel's heating equipment rebates cover high-efficiency gas furnaces and point to a participating contractor, and its heat pump rebates generally call for a Trade Partner Network contractor, so ask before you buy. Xcel's rebate summary also lists smart thermostats enrolled in AC Rewards and heat pump water heaters. Rural properties outside town may be on a cooperative for electric and propane for heat, which changes both programs, so check your bills.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

When a high-efficiency furnace moves to PVC venting, the gas water heater is left alone in a chimney sized for two appliances. Its small, cool exhaust may not draft well, and moisture condenses inside the chimney. That can mean backdrafting and a crumbling liner. The fix is a properly sized liner or a power-vent water heater, and we put it in the furnace quote instead of a change order.
Possibly, but check the registration. Many manufacturers only give the longer parts warranty if the equipment was registered online within 60 days of installation, and that step sometimes got missed on new construction. Send us the model and serial numbers and we can help look it up. Labor coverage from the original installer usually runs shorter than the parts warranty.
Clean or replace its filters every few months, wash the core once or twice a year as the manual describes, and clear leaves and snow off the outdoor intake and exhaust hoods. On an HRV, check that the condensate drain runs freely. Balancing the airflow takes instruments, so that belongs on a service visit. A neglected exchanger leaves the house stuffy and can make winter window condensation worse.
If the house already has a forced-air furnace, a coil on the furnace and a condenser outside use the existing ducts, after we check that they can carry cooling airflow. If the house has a boiler, or ductwork that won't work, ductless heads in the main rooms avoid opening walls. In Waverly's older homes the first floor often cools easily while the second floor needs its own solution.
