What we see in Littleton homes
Historic downtown, older houses. Littleton incorporated in 1890 and is the Arapahoe County seat. The blocks around Main Street hold some of the older houses in the south metro — basement furnaces in tight utility rooms, ductwork added and rerouted over the years, and flues that deserve a careful look during a tune-up.
Mid-century ranches and split-levels. Littleton grew quickly in the 1950s and 1960s. Many homes from that era are ranches with basements or split-levels, and the lower level of a split-level is often the coldest room in the house. Before blaming the furnace, we look at return air and how the duct runs were laid out.
A Littleton address isn't always the City of Littleton. Littleton mailing addresses cover a large area outside city limits, in unincorporated Jefferson, Arapahoe, and Douglas counties. That doesn't change the repair, but send your zip and the nearest cross street when you book so we can confirm a window.

Common questions
The lower level of my split-level is always cold. What can I do?
Keep lower-level registers open and returns clear, and swap the filter. If it's still cold, request a visit — split-levels usually need airflow work, not a bigger furnace.
How do I know if my older furnace is safe to keep running?
Furnaces and water heaters make carbon monoxide. A working battery detector is the first DIY item every house should have. If the detector alarms, there's a strange smell, or the breaker trips, shut the furnace down and request a visit.
