Most homes in RidgeGate, Meridian, Heritage Hills and Carriage Club run a mix of built-in refrigeration, gas ranges, and dishwashers from a handful of premium brands. We work on all of it under one visit whenever possible.
A single service call can address more than one appliance. If your Sub-Zero refrigerator is running warm and the Wolf oven downstairs won't hold a steady bake temperature, our technician can look at both during the same $89 diagnostic visit, since the fee is credited toward whichever repair you approve.
We carry a working stock of common seals, igniters, control boards, and compressor components on our service vans, which lets us close out a large share of repairs in a single trip rather than scheduling a return visit for parts.
What We Repair, By Category
Our work splits into a handful of core categories, each with its own failure patterns and parts logistics.
Refrigeration covers Sub-Zero, Viking, Thermador, and standard-depth refrigerators and freezers. Typical calls involve a warm fresh-food compartment, a freezer that's frosting over, water dispenser issues, or a compressor that short-cycles. Because Sub-Zero units use dual refrigeration systems and sealed evaporators, a proper diagnosis usually means checking airflow, defrost timing, and refrigerant charge before anything gets replaced.
Cooking appliances span Wolf and Viking ranges, wall ovens, and gas and induction cooktops. At our altitude near 5,980 feet, gas appliances need a different air-to-fuel mixture than what a unit ships with for sea level, so igniter behavior, burner flame quality, and oven temperature swings often trace back to calibration rather than a failed part.
Dishwashers and wine coolers round out the list. Dishwasher calls usually involve drainage, a control panel that won't respond, or racks that won't lock, while wine cooler issues are almost always thermostat or compressor related, since even a few degrees of drift can put a collection at risk.

Service Categories at a Glance
A quick look at the appliance types we handle most often across Lone Tree, Castle Pines, Parker, and Highlands Ranch homes.
A gas oven that runs 25 degrees hot at sea level can run 40 degrees hot at 5,980 feet if it was never recalibrated for altitude. We check that on every range and oven call in this area.

Lone Tree Appliance Repair, by the Numbers
What appliances does Lone Tree Appliance Repair service?
We repair built-in and standard refrigerators, wine coolers, gas and induction ranges, wall ovens, cooktops, and dishwashers from brands like Sub-Zero, Wolf, Viking, and Thermador. Call Lone Tree Appliance Repair at (720) 575-1433 to describe your appliance and symptoms and get scheduled.
Is Lone Tree Appliance Repair authorized by Sub-Zero or Wolf?
No. Lone Tree Appliance Repair is an independent repair company and is not authorized, certified, or affiliated with Sub-Zero, Wolf, Viking, or any other manufacturer. We use OEM-quality parts and are experienced with these brands, and you can reach us at (720) 575-1433 with questions.
How much does a service call cost and can multiple appliances be fixed in one visit?
There's an $89 diagnostic fee that gets credited toward the repair once you approve the work, and yes, a technician can look at more than one appliance during the same visit. Final pricing depends on the on-site diagnosis. Call (720) 575-1433 to schedule.
Do you offer same-day or same-week appointments?
In most cases yes, especially for calls placed earlier in the day. Our phone line is answered 24/7 at (720) 575-1433, and service visits run daily from 8:00 AM to 6:00 PM.
What's included in the $89 diagnostic fee?
It covers the technician's time to inspect the appliance, run relevant test cycles, and identify the cause of the problem, along with a written repair quote. If you approve the repair, the $89 is credited toward the total.
Why does altitude matter for my gas range or oven?
Lone Tree sits near 5,980 feet, and gas appliances are calibrated at the factory for a specific air-to-fuel ratio. At this altitude, igniters, burner flames, and oven regulators often need recalibration to prevent weak ignition, uneven flame, or inaccurate oven temperatures.
Do you work on appliances outside Lone Tree?
Yes. We regularly service Castle Pines, Parker, Centennial, Highlands Ranch, Castle Rock, Greenwood Village, and Littleton, including the Park Meadows and DTC areas.
What parts do you use for repairs?
We use OEM-quality, factory-specified parts for every repair, matched to the exact model and appliance system so the fix holds up the way the original component was designed to.
Rated 4.9 by Lone Tree-area homeowners
Sub-Zero column refrigerator stopped cooling after a power fluctuation. Tech arrived next morning, diagnosed a control board fault, sourced the part, and had everything running within four days. The $89 diagnostic was credited toward the repair — exactly as promised. Truly professional.
Wolf dual-fuel range burners were flaring unevenly at different heights. Diagnosed as an altitude calibration issue: gas pressure wasn't adjusted for nearly 6,000 feet. Fixed on the spot. This is the specialist knowledge you simply cannot get from a generic repair company.
Miele dishwasher failed to drain mid-cycle. Called at 7 PM, a real person answered. Next-morning visit, drain pump replaced, done in under two hours. Clean work, honest quote before they touched anything. Will use again without question.
Viking refrigerator repair required a part order and a return visit, but communication was consistent throughout and the final price was exactly as quoted. The refrigerator has run without issue ever since. Good experience overall.
Thermador range spark igniter failed on all four burners. Single-visit diagnosis and repair — the technician had the correct igniter assembly in his truck. Diagnostic fee credited to the repair, no surprises on the bill. Clearly knows Thermador.
Sub-Zero wine cooler was drifting off temperature. Technician found a defrost heater fault and thermocouple calibration drift — both repaired in the same visit. Very impressed with the depth of knowledge about high-end Sub-Zero refrigeration.
Wolf wall oven convection fan seized right before the holidays. They worked us in on short notice, replaced the fan motor, and had the oven back in service for Christmas dinner. Above and beyond.
Gaggenau oven throwing error codes. Correct diagnosis on first visit — temperature probe failure — part in stock, repaired same day. The technician's familiarity with Gaggenau specifically was evident. Exactly the service these appliances deserve.
