Why Is My Thermostat Screen Blank, and Is the Furnace or AC Still Working?
A blank thermostat screen usually means lost power: dead batteries, a tripped furnace switch, a blown board fuse or a condensate switch. What to check first.

Woodbury grew from a township of about 3,000 people in 1960 to more than 75,000 today, and most of its homes are two-stories built from the 1980s through the 2000s.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Woodbury and across Washington 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.

Book in WoodburyWoodbury's first subdivision, Woodbury Heights, went in off Afton Road in the northwest corner of the township in 1955, and sewer and water lines followed in the early 1960s. Growth took off once Interstate 94 opened along the city's northern edge in the 1980s. From about 10,000 residents in 1980, Woodbury added 26,000 more in the 1990s, 15,000 more in the 2000s and 13,000 more in the 2010s. Houses from the 1950s through the 70s are ramblers and split-levels, many on their third furnace; the 1980s and 90s are mostly two-stories on their second.
Houses from the last 25 years are the tightest in the city, with condensing furnaces, air exchangers, and often a finished lower level with its own supply runs. The oldest are the leakiest, with chimney venting and original ductwork. That spread means a replacement quote in Woodbury Heights and one in a 2015 two-story can look nothing alike, even a few miles apart.
Woodbury's post-2000 houses are tight enough that the air exchanger matters in winter. When it's off or its filters are clogged, moisture from cooking, showers and breathing builds up and shows as frost in window corners and water on the sills. When its core frosts up or the fans are out of balance, the fresh air comes in colder than it should and a nearby room turns chilly. Clean the filters and core each fall, and have the airflow balanced if one room runs cold.
In summer the air exchanger can work against you on muggy days. An HRV brings in outdoor air all day and night, and on a humid July afternoon that air carries moisture the AC then has to remove. Running it on a lower or intermittent setting during the stickiest weeks helps, and an ERV, which keeps some of that moisture outside, is worth considering when the unit is replaced. Upstairs, keep bedroom doors open or add return paths so the second floor isn't starved of airflow.
Woodbury homes get both gas and electricity from Xcel Energy. For the matched furnace-and-AC replacements common in the city's 1990s and 2000s houses, Xcel has separate rebates for the high-efficiency gas furnace and for central AC or an air-source heat pump, and several require an Xcel-registered contractor. Xcel's list also covers smart thermostats enrolled in AC Rewards and heat pump water heaters. Ask which rebates apply before you choose equipment, since efficiency tiers decide eligibility.
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.

If both are original to a 1990s or early-2000s house, usually yes. The indoor coil sits on the furnace, so replacing both lets us match the coil to the new condenser under its SEER2 rating and run the line set and electrical once. You also get one 2-year labor warranty covering the whole system. If one piece is much newer, we'll say so and quote them separately.
It has a cold floor over an unheated garage, three exposed walls and usually the longest duct run in the house, often with no return. We check the insulation under the floor, the duct size and the balancing damper first. If the run can't carry enough air, a small ductless heat pump head in that room is often cheaper than upsizing the whole system.
Quite different. Woodbury Heights dates to 1955, so a house there has more in common with a first-ring suburban rambler than with a 2000s two-story. Expect chimney venting, or a water heater left in the chimney after a furnace upgrade, ductwork sized for heat, and no air exchanger. The quote centers on venting, return air and whether the ducts can carry central air, rather than on matching builder equipment.
Often, if the furnace has years left. The heat pump replaces the AC condenser, the indoor coil is swapped for one matched to it, and a dual-fuel control decides when the furnace takes over. Furnaces from the 2000s usually work with that setup, though the blower and control board need checking. With Xcel supplying both fuels, we set the changeover point by comparing your gas and electric rates.
