Windsor is a separate town, not a Fort Collins neighbourhood — about 15 to 17 miles east and south-east of Fort Collins, about 10 to 15 minutes via CO-392 or Crossroads Boulevard (one source says 17 miles and about 27 minutes), and one of Northern Colorado's fastest-growing family communities, with a population of about 35,000. It is a new-construction-heavy market: historic downtown bungalows beside Water Valley lake and golf homes and new master-planned communities — RainDance, Seven Lakes, Cornerstone and The Timbers — with a median sale price of about $588,000–$589,950 in July–August 2026.

Windsor calls for first-time AC, furnace work on new builds, smart controls for zoned homes, and ventilation for finished basements.
Adding AC to a Windsor home built with furnace-only heat is the most common job in town. We check the ductwork first — where it can carry cooling airflow we use it, and where it cannot we size a ductless system instead.

View details ↗04A finished basement needs balanced air, not just a bigger box. We install and service zoning controls, extend ductwork into finished space, and verify airflow with static-pressure testing.

Many Windsor homes were built with a furnace and no air conditioning. The ductwork was built for heating, and it may not carry cooling airflow — or the home may have no ducts worth using at all.
We test the ductwork before recommending anything. Where the ducts work, we add a ducted system; where they do not, a ductless mini-split heats and cools without them.
Book a visit →A builder warranty ends, and the system that was “new” is suddenly the homeowner's responsibility. The check at that point is maintenance, refrigerant charge, duct leakage and thermostat configuration — the items that protect the system's life.
We service warranty-age systems and can advise on what is covered before any work starts. Check your builder warranty documents, because warranty-age work needs to protect the warranty rather than void it.
Book a visit →An unfinished basement that becomes living space needs duct extensions, zoning and a system that can carry the extra load. A system sized for the original floor plan will not heat and cool a finished basement.
We extend ductwork, add zoning controls and re-balance the system room by room, verifying airflow with static-pressure testing. A bigger system on leaking ducts just wastes more energy.

Downtown, the lake and the new communities are the anchors of Windsor. Tell us which one you are near when you book.
The downtown bungalows anchor the historic core and are the best reference for the retrofit streets.
The lake and golf community is a useful reference for the lakefront homes and their humidity and IAQ needs.
The new master-planned community with resort amenities anchors the newest phases of town.
The lake community on the eastern side of town is a reference for the newer subdivisions.
Windsor sits about 15 to 17 miles east and south-east of Fort Collins via CO-392 or Crossroads Boulevard — about 10 to 15 minutes, though one source says 17 miles and about 27 minutes. It is a separate town with its own downtown and its own housing market. If your home is in Windsor, it is on our Windsor route.
