What HVAC maintenance does a Hudson, WI home need?
A furnace tune-up each fall and an AC tune-up each spring, plus filter changes, clear PVC vent pipes and a clear outdoor unit between visits. Newer, tighter homes also need the air exchanger serviced. Hudson follows Wisconsin programs such as Focus on Energy, and our prices match the Minnesota side.
Key points
- Fall furnace tune-up in September or October, spring AC tune-up in April or May.
- Hudson homes are served by Xcel Energy's Wisconsin company, and Wisconsin programs like Focus on Energy apply.
- Older houses near downtown bring boilers and tight basements; post-2000 houses bring PVC-vented furnaces and air exchangers.
- Newer, tighter homes need their air exchanger serviced along with the furnace.
- Our tune-up prices are the same in Hudson as in Minneapolis: $129, or $219 for both.
A Hudson home needs a furnace or boiler tune-up each fall, an AC tune-up each spring, and a few homeowner checks in between: filters, the PVC vent pipes after snowstorms, the outdoor unit, and in newer houses the air exchanger. Hudson sits on the St. Croix at the Wisconsin end of the I-94 bridge, a few minutes from the Minnesota side. The winters are the same as in the Twin Cities. The state rules, the utility programs and a good share of the houses are not. Most maintenance advice written for Minneapolis still applies here, with a few Hudson-specific differences that change what you should check and where you look for help paying for upgrades.
Two kinds of Hudson houses
Hudson was settled in 1840, and the blocks near downtown and the riverfront still hold houses from the lumber and railroad years. Those homes bring their own maintenance list: boilers and radiators, furnaces that replaced old gravity systems, tight basements with little room to work, and chimneys that may now vent only a water heater. For these houses, the fall visit is the important one. Boilers need pressure, relief valve and circulator checks, and an older furnace in a cramped basement needs its venting and clearances looked at every year.
Most of the city's growth came after 2000: subdivisions of two-stories, walkouts and townhomes. Those houses were built tight, with sealed-combustion furnaces venting through white PVC pipe and air exchangers bringing in fresh air. Their original builder equipment is now aging, and the maintenance list shifts toward condensate drains, PVC vent terminations, humidity and ventilation. One- and two-family homes built in Wisconsin since 1980 fall under the state's Uniform Dwelling Code, so these houses were built to Wisconsin's rules for insulation, venting and ventilation, even when the owners commute to Minnesota.
Who supplies gas and electricity in Hudson, WI?
In the city of Hudson, Xcel Energy provides both gas and electricity, operating in Wisconsin as Northern States Power–Wisconsin. Out in the surrounding townships, utility service depends on your address, and some rural homes heat with propane.
That matters for rebates. The Xcel and CenterPoint rebate pages you'll find in Minnesota articles are for Minnesota customers. Wisconsin's statewide efficiency program is Focus on Energy, and Xcel runs its Wisconsin programs separately from Minnesota's. Focus on Energy's IRA home energy rebates (HEAR) are open to income-qualified households, and most of those rebates require an IRA Registered Contractor. Check the Focus on Energy HEAR page for current terms, and ask any contractor whether a rebate needs a registered installer before you count on it.
Wisconsin also has its own carbon monoxide alarm law (Wis. Stat. 101.647): homes with fuel-burning appliances need a CO alarm in the basement and on each floor level. Test them each fall when the furnace starts up.

When should you book a furnace tune-up in Hudson?
Book the heating tune-up in September or early October, before the first cold night puts every furnace to the test in the same week. Before we arrive:
- Change the filter and note the date.
- In newer homes, walk outside and check the PVC intake and exhaust pipes. On some walkouts they exit low on a wall where drifts pile up. Mark them with a stake so they're easy to find and clear after a storm.
- Swap the humidifier pad and set the humidity lower as it gets colder outside.
- If you're on propane, check the tank level and schedule a fill before deep cold.
In the older houses near downtown, the fall list looks different. With a hot-water boiler, write down where the pressure gauge sits when the system is cold so you'll notice if it changes, bleed air from any radiator that stays cool at the top, and look for water at the relief valve or on the floor around the boiler. If the furnace was replaced with a high-efficiency model at some point, the water heater may now be the only thing venting into the old chimney, and a chimney that's too big for it can draft poorly. Ask the technician to check it.
Our fall furnace checklist walks through the full homeowner list, and our page on furnace repair in Hudson covers the problems we see most in the city's PVC-vented furnaces, like clogged condensate traps and frozen drain lines.
When should you book an AC tune-up in Hudson?
Book the AC tune-up in April or May. Cottonwoods grow along the river, and their June fluff can blanket an outdoor coil in days. If your yard gets it, rinse the coil again once the fluff stops falling. Our spring AC checklist lists what to check yourself and what the technician covers.
Many of the city's condensers went in with the houses in the early 2000s and are near the end of a normal life; our page on AC repair in Hudson covers the failures that age brings. In the post-2000 two-stories, a bonus room over the garage that bakes in July is a common complaint. A tune-up won't fix that, since it's usually a duct or insulation problem. A ductless mini-split is one fix; our post on mini-split costs in Western Wisconsin runs the numbers.
Between visits
- Change the filter on schedule, more often with pets.
- Keep the air exchanger's filters clean in a tight newer home. A clogged one leaves stale air and winter window condensation; our ventilation page covers HRV and ERV service.
- Keep supply registers and return grilles open and unblocked.
- Leave the outdoor AC uncovered in winter, clear of snow and plant growth.
- Clear snow from PVC vent pipes after every big storm.
- If you have a heat pump, get it checked before both seasons, since it works year-round.
When should a Hudson homeowner stop and call for HVAC help?
- You smell gas. Leave the house, then call Xcel Energy or 911 from outside.
- A CO alarm sounds. Get everyone out and call 911 first.
- The boiler's pressure climbs well above where you noted it cold, or the relief valve drips or discharges.
- The furnace locks out again after one reset, or the vent pipes are clear and it still won't light.
- Water collects around the furnace, the AC coil or the condensate pump.
No-heat calls get priority, and we're open 7 days, 7am–9pm.

Questions
Do Minnesota rebates apply to my Hudson home?
No. Hudson is in Wisconsin, where Xcel Energy operates as Northern States Power–Wisconsin and statewide efficiency incentives run through Focus on Energy. The Xcel and CenterPoint rebates in Minnesota articles are for Minnesota customers. Check Focus on Energy and Xcel's Wisconsin pages for current offers, and ask whether a rebate needs a registered contractor before you count on it.
Do you charge more to come to Hudson?
No. Our prices are the same across the Twin Cities and the roughly 50 miles around them, including Hudson, River Falls and Prescott. A furnace or AC tune-up is $129, both together are $219, and repair calls carry the same $79 trip charge as anywhere else, waived when you approve the repair.
Are you licensed to work in Wisconsin?
Yes. We're licensed in both Minnesota and Wisconsin and insured, so Hudson homes get the same service, pricing and written quotes as homes on the Minnesota side. When a replacement needs a permit, it goes through the local permit office for your address, under Wisconsin's rules rather than Minnesota's.
How often should an air exchanger be serviced?
Check the manufacturer's manual, but most HRVs and ERVs need their filters cleaned or changed a few times a year and the core cleaned periodically. In a tight post-2000 Hudson home, a neglected air exchanger shows up as stale air, higher humidity and window condensation in winter. We look at it during the furnace tune-up if you ask.
