Rigden Farm is a 308-acre master-planned community at the south-east corner of South Timberline Road and Drake Road, with access from Timberline in the west, Drake in the north and County Road 9 in the east. Annexed in 1988, with its Overall Development Plan approved in April 1999, Phase I construction from October 1999 and Phase II from fall 2001, its homes were built between 2000 and 2011 — ranch and two-storey homes, townhomes and condos, around a neighbourhood commercial centre at Timberline and Custer. Those homes are now hitting furnace and AC replacement together, and that is the Rigden Farm story.

Rigden Farm calls for first-replacement furnaces and ACs, zoning for two-storey comfort, and systems that fit townhome and condo constraints.
A 2000–2011 furnace is reaching the end of its life. Since 1 January 2026, Colorado's HB23-1161 rule means new furnaces must meet the ultra-low-NOx standard of 14 ng/J or less — a condensing unit with PVC venting and a condensate drain.
View details ↗02New AC in a Rigden Farm home means sizing for the house, not the square footage alone. We run a Manual J load calculation at altitude — 5,003 feet cuts AC capacity roughly 10–20% against sea-level ratings — and verify the ductwork can carry the airflow.
View details ↗03Zoning starts with control. A properly wired and configured smart thermostat — with the right staging for a two-storey home — is what makes a zoned system actually work, instead of fighting itself.
View details ↗04Two-storey master-plan homes need balanced air, not just a bigger box. We install and service zoning controls, balance airflow room by room, and verify it with static-pressure testing.
View details ↗A single build decade, a single replacement wave, and a mix of single-family, townhome and condo. The work here is planned replacement, not guesswork.
A home built in 2003 has a furnace nearing 25 years and an AC past 20. Replacing one without looking at the other wastes a truck roll and a second disruption — and the two systems share ductwork, venting and controls.
We assess the furnace and the AC together and give you the combined picture: what can wait, what cannot, and what a paired replacement saves against two separate jobs.
Book a visit →LaGrange condominiums and the Flats at Rigden Farm have shared walls, limited outdoor space and HOA-maintained exteriors. A standard split system does not always fit, and the HOA has a say in what goes outside.
Compact outdoor units and ductless mini-splits are the practical answer here. We confirm the HOA's exterior-equipment rules before we start — check your HOA covenants, and we will work within them.
Book a visit →The most common Rigden Farm complaint is the second floor: hot in July, cold in January. The cause is usually distribution — duct leakage, unbalanced dampers, a system sized for the ground floor — not a lack of capacity.
We test duct leakage and static pressure, balance the system room by room, and add zoning controls where the ductwork allows it. A bigger system on leaking ducts just wastes more energy upstairs.

Rigden Farm's landmarks are the shops, the schools and the trails. Tell us which one you are near when you book and the technician will find the street.
The neighbourhood commercial centre at Timberline and Custer anchors the community and is the best reference for the western streets.
At 5844 South Timberline Road, established in 2003, the school marks the southern edge of the community.
The trail runs close to the community and is a useful reference for the streets on the southern and eastern edges.
The centre sits adjacent to the community, across the constructed lake and wetlands buffer on the eastern side.
Rigden Farm sits at the south-east corner of South Timberline Road and Drake Road / Custer Drive, with access from Timberline in the west, Drake in the north and County Road 9 in the east. If your address is inside that 308-acre master plan, it is on our Rigden Farm route.

Call (970) 932-2324 →Often, yes — or at least assess both together. A 2000–2011 home is hitting furnace age (20–25 years) and AC age (15–20 years) at the same time, and the two systems share ductwork, venting and controls. We give you the combined picture: what can wait, what cannot, and what a paired replacement saves against two separate jobs.
The Rigden Farm HOA exists and maintains open space, parks and landscaped buffers. Whether it restricts condenser placement or screening is not verified in our sources — check your HOA covenants before moving or replacing exterior equipment, and we will work within whatever they say.
Usually, yes — if the ductwork allows it. Zoning works through dampers, thermostat controls and balanced airflow, and it starts with a duct leakage and static-pressure test. If the ducts leak, sealing and balancing come first; a bigger system on leaking ducts will not fix the upstairs.
As of November 2026: Xcel offers $1,500 per heating ton for cold-climate heat pumps (from 1 October 2026), and Colorado offers a $1,000 state heat-pump tax credit, claimed by the contractor and worth at least a $333 customer discount. Amounts change. The federal 25C/25D credit expired on 31 December 2025 and the Xcel $225 furnace rebate was removed on 1 January 2026.
Yes. LaGrange condominiums and the Flats at Rigden Farm are a regular part of this route. Compact outdoor units and ductless mini-splits suit the limited outdoor space, and we confirm HOA rules on exterior equipment before we start.
