About Lone Tree Appliance Repair
A local, independent repair shop built around one idea: show up, diagnose it right the first time, and fix it with parts that last.
How we got started
Lone Tree Appliance Repair opened in 2014 with a single service van and a simple territory: the I-25 corridor between Highlands Ranch and Castle Rock.
The founder had spent years on factory-authorized service crews, driving from Aurora to Colorado Springs to work on high-end kitchens, and kept noticing the same gap. Homeowners in Lone Tree, Parker, and Castle Pines wanted a technician who actually lived nearby, knew the neighborhoods, and could get to a broken refrigerator before the food inside went bad. So the business started local and stayed local, building a route that now covers Centennial, Greenwood Village, and Littleton alongside its home base.
We are not a franchise and we are not on anyone's authorized service network. Sub-Zero, Wolf, Viking and the other brands we work on all have their own certified programs, and this company is not part of them. What we offer instead is independence: we choose parts based on what actually fixes the appliance correctly, we're not bound to a single manufacturer's service scripts, and we answer the phone ourselves at (720) 575-1433 around the clock, every day of the year.
What running an independent shop actually means
Being unaffiliated isn't a marketing angle here, it changes how a repair gets done.
When a tech from an authorized network diagnoses your Wolf range, they're often working from a script that leads toward specific part numbers and specific labor codes, regardless of whether a cheaper fix or a rebuilt component would solve the problem just as well. Our techs diagnose first and price second. The $89 diagnostic fee covers a real inspection, not a sales pitch, and that fee comes off the final invoice if you move forward with the repair.
It also means we can work across brands in a single visit. A lot of homes in RidgeGate and Heritage Hills have a Sub-Zero refrigerator, a Wolf range, and a Viking or Bosch dishwasher all in the same kitchen. One call, one technician, one invoice, instead of three different authorized networks with three different hold times.
Altitude is part of the job description
At roughly 5,980 feet, Lone Tree sits high enough that gas appliances behave differently than they do at sea level.
Thinner air changes the air-to-fuel ratio a gas range or oven needs to burn cleanly, which is why factory default settings on a range shipped from a lower elevation can leave you with a yellow-tipped flame, a slow-igniting burner, or an oven that runs hot or cold against its dial. Every technician on our team is trained to check and adjust orifices, igniters, and gas regulators for our elevation, not just swap parts and leave. It's a detail a lot of national chains overlook because their training materials assume sea-level installs.
What happens when you call
The process is the same whether you're in a RidgeGate townhome or a Carriage Club estate kitchen.
- 01
You call or book online
Reach a live person at (720) 575-1433 any hour, or request a visit through our online booking page. We ask for the brand, model if you have it, and what the appliance is doing.
- 02
We schedule a same-week visit
Service runs 8:00 AM to 6:00 PM daily, and most Lone Tree, Parker, and Castle Rock addresses can get an appointment within the week, often sooner.
- 03
The technician diagnoses on site
The $89 diagnostic fee covers a full inspection of the unit, including elevation-related checks on gas models, and you get a specific repair quote before any work starts.
- 04
We repair with OEM-quality parts
If you approve the quote, we complete the repair using OEM-quality or factory-specified parts and the diagnostic fee is credited against the final bill.
Independent shop vs. authorized service network
Both models have their place. Here's the practical difference homeowners in our service area tend to notice.
| Factor | Lone Tree Appliance Repair | Manufacturer-authorized network |
|---|---|---|
| Scheduling window | Often same week, phone answered 24/7 | Call center hours, booking can run 1-3 weeks out |
| Brands serviced per visit | Sub-Zero, Wolf, Viking, and most major brands in one trip | Typically limited to that one brand's network |
| Diagnostic approach | On-site inspection, $89 fee credited to repair | Varies by contracted labor guide |
| Altitude calibration | Standard check on gas ranges, cooktops, and ovens | Depends on individual technician training |
| Warranty work | Not eligible for manufacturer warranty claims | Required for active factory warranty repairs |
Is Lone Tree Appliance Repair authorized by Sub-Zero, Wolf, or Viking?
No. Lone Tree Appliance Repair is an independent, locally owned company and is not authorized, certified, or affiliated with Sub-Zero, Wolf, Viking, or any other manufacturer. We use OEM-quality parts and standard repair procedures, but if your appliance is under active factory warranty, that claim needs to go through the manufacturer's own authorized network. Call (720) 575-1433 to ask which applies to your situation.
How long has this company been in business and where do they work?
Lone Tree Appliance Repair was founded in 2014 and has served the south Denver I-25 corridor since then, including Lone Tree, Castle Pines, Parker, Centennial, Highlands Ranch, Castle Rock, Greenwood Village, and Littleton. The phone at (720) 575-1433 is answered 24/7, and service visits run daily from 8:00 AM to 6:00 PM.
Do they charge extra for gas ranges because of Lone Tree's elevation?
There's no separate elevation surcharge. The standard $89 diagnostic fee, which is credited toward the repair, covers checking and adjusting air-to-fuel mixture, igniters, and gas regulators for our roughly 5,980-foot elevation as part of a normal gas range, cooktop, or oven diagnosis. Call (720) 575-1433 for a quote specific to your model.
Do you work on all major appliance brands or just luxury brands like Sub-Zero and Wolf?
We service both. Our technicians regularly work on Sub-Zero, Wolf, and Viking equipment alongside mainstream brands like Whirlpool, GE, Samsung, LG, and Bosch, so one visit can often cover an entire kitchen.
What does the $89 diagnostic fee actually cover?
It covers a technician's full on-site inspection of the appliance, including a specific written quote for the repair before any work begins. If you approve the repair, that $89 is subtracted from the final invoice rather than charged on top of it.
Can I book a technician online instead of calling?
Yes. You can request an appointment through our online booking page at any time. For same-day or urgent issues, calling (720) 575-1433 directly is usually faster since the phone is staffed 24/7.
Which neighborhoods and cities do you actually serve?
Our regular service area covers Lone Tree, including RidgeGate, Meridian, Heritage Hills, and Carriage Club, plus Castle Pines, Parker, Centennial, Highlands Ranch, Castle Rock, Greenwood Village, and Littleton.
What kind of parts do you use for repairs?
We use OEM-quality and factory-specified parts chosen for the specific model and issue, not generic aftermarket substitutes, so the repair holds up under normal use.
