Appleton HVAC built for Wisconsin reality. Furnace dies at 2am in January. AC quits the week of the EAA fly-in. We answer the phone and get there fast — across the Fox Valley.
The Fox Valley has one of the most punishing HVAC environments in the country. 120-degree annual temperature swing. A January cold snap can hit −25°F. The same furnace and ductwork has to keep up with 95°F-and-humid days in August. Most systems engineered for a moderate climate fail here within a decade.
Then there's the housing stock. Appleton's older neighborhoods — north of College, the Highland District, Old Third Ward — are full of 1920s and 1930s homes with radiator boilers, octopus furnaces, and zero original ductwork. Retrofitting central air into a balloon-framed 1925 home is its own science. We do it constantly.
And the newer side: Greenville, Springwood, and the developments east of County A built after 2000. These have tighter envelopes, higher loads from finished basements, and ductwork sized for code minimums. Most of them benefit from a properly-sized two-stage furnace and a variable-speed AC, not the single-stage builder-grade units they came with.
The point: "installing a furnace" isn't a generic job. The right system for a 1929 Appleton four-square is not the same as the right system for a 2018 Greenville two-story. We size and engineer for your actual house.
Full residential and light commercial HVAC across the Fox Valley. Same-day emergency dispatch for no-heat and no-AC calls. Scheduled service typically inside a week.
No heat at 2am. Loud bangs at startup. Short cycling. Cracked heat exchangers in older Lennox and Carrier units we see all over Appleton. Same-day diagnostic.
Not cooling when it's 92°F and humid. Frozen evaporator coil. Capacitor failures. Refrigerant leaks. Most of what we see is fixable — replacement only when the math actually says so.
Sized for your home, not a spec sheet. Furnace, AC, heat pump, mini-split. Manual J load calc included. Financing available.
Adding central air to an older Appleton home with no ducts. Sealing leaky returns in newer Greenville builds. We don't just patch — we measure airflow before and after.
Whole-house humidifiers for dry Wisconsin winters. Dehumidifiers for muggy summers. HEPA, MERV-16, and UV systems for allergy sufferers.
Spring AC tune-up. Fall furnace check. Catches the failures that would otherwise hit on the coldest or hottest day of the year. Discounts on parts and priority service included.
Different problems each season. We're ready for both.
Below-zero stretches mean your furnace runs at near 100% capacity for days. That's when components fail. We run 24/7 emergency in winter — usually 4-6 trucks rolling on a sub-zero week.
Fox Valley summers run 85-95°F with brutal humidity off Lake Winnebago. AC units sized for code-minimum loads get pushed past their design point. Failures spike during EAA week.
24/7 emergency HVAC for no-heat, no-AC, and major failures across the Fox Valley. Most calls answered in under 10 minutes.
920-470-2542HVAC contractors who size systems for the actual climate — not a generic spec sheet.
State-certified contractor. Refrigerant certified, ductwork code-compliant.
4-6 trucks rolling overnight during sub-zero cold snaps. No voicemail.
We size systems based on your actual house, not your square footage.
If repair is the right answer, we say so. Even when replacement pays better.
The questions Fox Valley homeowners ask us most.
No-heat calls in single-digit or sub-zero weather get priority dispatch. During a cold snap we run 4-6 trucks 24/7 across the Fox Valley. From the time you call, we're typically at your house in under 90 minutes — usually faster in the immediate Appleton city limits.
Yes, and we do this constantly in the Highland District and Old Third Ward. The two common approaches are: high-velocity ductwork (small flexible tubes that fit between joists, no major wall opening), or a multi-zone mini-split heat pump system. Both work well in older Appleton homes. We'll walk through the trade-offs on a free in-home estimate.
Standard 80% efficiency furnaces typically last 15-20 years. High-efficiency 95-97% units typically 12-18, because they have more components and run more cycles. The cold here works systems harder than southern climates — the Fox Valley average heating load is about 7,000 heating degree days, roughly 2x what a system designed for Kansas City would see.
Modern cold-climate heat pumps (the ones rated to perform at −15°F or lower) are absolutely worth considering, especially if you have natural gas costs above $1.50/therm. We typically pair them with a high-efficiency gas furnace as backup — hybrid systems are the sweet spot for the Fox Valley climate. They'll handle 90% of your heating hours, then the gas furnace kicks in on the coldest days.
If you'd rather not be the one calling at 2am with no heat, yes. A spring AC tune-up catches refrigerant leaks and capacitor failures before they fail. A fall furnace check catches cracked heat exchangers, weak igniters, and pressure switch issues before they hit. Most plans run $180-$240/year and pay for themselves in one avoided emergency call.
