Olathe, KS
Family, Women & Veteran Owned • Serving Johnson County Since 2003
Full Nelson serves Olathe homeowners with honest, reliable plumbing and HVAC work. As the Johnson County seat and one of the fastest-growing cities in Kansas, Olathe has homes ranging from 1970s construction to brand-new builds. Our team handles them all. I-35 and our Leawood office put us within quick reach when you need service.
We Exceed Expectations
Olathe has grown from a small Santa Fe Trail stop into a city of over 140,000 people. That growth brought decades of residential construction, from established subdivisions built in the 1970s to new developments breaking ground today. Full Nelson understands the plumbing and HVAC needs across all of them.
We opened our doors in 2003 as a Family, Women and Veteran owned company. Our approach has stayed the same since day one: tell customers what we find, explain their options, and let them decide. No pressure, no upselling. Our Leawood office at 4901 W. 136th Street and quick I-35 access means we reach Olathe homes fast when emergencies happen.

Our licensed plumbers understand these local conditions and provide solutions that last.

- Water softeners

Drain Cleaning
A slow drain usually signals a bigger problem forming in your pipes. Tree roots, grease buildup, and years of accumulated debris can restrict water flow and eventually cause backups. Full Nelson uses professional-grade equipment to clear drains and identify underlying issues before they become emergencies.
For more serious issues, we offer:
- Drain cleaning
- Rooter services
- Clogged sinks
- Showers
- Floor drains
-
Sewer Repair and Replacement
Sewer problems announce themselves through slow drains, gurgling toilets, and unpleasant odors in your yard. Ignoring these signs leads to raw sewage backing up into your home. Full Nelson inspects sewer lines with video cameras to pinpoint damage, then recommends the most practical repair based on what we find.
Our services include:
- Sewer line repair and installation
- Sewer video inspection
- Trenchless excavation using pipe bursting technology
-
Sump Pumps and Battery Backup Systems
Spring storms drop heavy rain on Olathe, and that water has to go somewhere. Many homes rely on sump pumps to keep basements dry. When the pump fails during a storm, water damage follows quickly. Full Nelson installs, repairs, and replaces sump pumps and adds battery backup systems that keep pumping when the power goes out.
Our services include:
- Sump pumps
- Battery backup systems
-
Gas Leaks and Gas Repairs
The smell of natural gas means you need help immediately. Even small leaks create explosion and health risks for your family.

Our services include:
- Gas leak detection
- Gas leak repair
- Gas line testing
- Gas line installation
-
Toilet Repairs and Replacements
A toilet that runs constantly wastes hundreds of gallons each month and drives up your water bill. A toilet that clogs repeatedly signals a problem in the drain line or the fixture itself.

Our services include:
- Toilet repairs & replacements
- Flapper replacements
- Toilet rebuilds
- Water-efficient toilets
-
Faucets and Shower Valves
That dripping faucet is more than an annoyance. Left alone, it wastes water and can damage sink basins and countertops.

Full Nelson repairs and replaces faucets, shower valves, and tub fixtures from all major manufacturers.
Our services include:
- Kitchen faucets
- Bathroom faucets
- Shower valves
- Tub fixtures
-
Water Filtration
Municipal water treatment removes most contaminants, but chlorine taste, sediment, and trace minerals still reach your tap. A whole-home filtration system addresses these issues at the source, protecting your family and extending the life of appliances that use water. Full Nelson tests your water quality and installs filtration matched to what we find.
Our services include:
- Whole-home water filtration systems
- Water quality assessment
- Filtration solutions
-
Water Softeners
Hard water leaves white scale on fixtures, spots on glassware, and residue that makes hair and skin feel dry after showering. Over time, mineral deposits damage water heaters and reduce their efficiency. A water softener removes calcium and magnesium before they cause problems. Full Nelson sizes and installs systems based on your household’s water usage.
Our services include:
- Water softeners
- Water softener installation
- Water softener service
-
Well Pumps and Well Tanks
Rural properties in the Olathe area often rely on private wells. When the pump fails or the pressure tank loses its charge, water stops flowing to every fixture in your home.

Our services include:
- Well pumps & Well tanks
- Low water pressure issues

Water Main Line Repair and Replacement
The water main carries every drop of water your household uses. A leak in this line can waste thousands of gallons before you notice your bill spike. Signs include unexplained wet spots in your yard, low water pressure, or discolored water at your taps. Full Nelson locates water main damage and repairs or replaces the line to restore full service.
We offer:
- Water main line repair
- Water main line replacement
- Restoring water service
-
Sewer Line Repair and Replacement
Mature trees throughout Olathe send roots seeking moisture, and your sewer line is a prime target. Roots enter through tiny cracks, then grow until they block the pipe entirely. Aging clay and cast iron pipes in older neighborhoods become brittle and collapse. Full Nelson inspects sewer lines with cameras and recommends repair or replacement based on actual conditions.
Our services include:
- Sewer line repair
- Sewer line replacement
- Video inspection
- Recommending a solution
-
Septic Tank Repair and Replacement
Properties outside Olathe’s municipal sewer service rely on septic systems to handle wastewater. These systems work quietly for years but eventually need repair or replacement. Warning signs include sewage odors, wet areas over the tank or drain field, and drains that empty slowly throughout the house. Full Nelson inspects septic systems and completes repairs to restore proper function.
Our services include:
- Septic tank repair
- Septic tank replacement
- System inspection
- Identifying issues
-
Septic Lateral Field Repair and Replacement
The drain field disperses treated water from your septic tank into the soil. When these underground lines clog or collapse, wastewater has nowhere to go. You may notice soggy ground, foul smells, or sewage surfacing in your yard. Full Nelson evaluates lateral field damage and performs repairs or full replacement to get your system working again.
Our services include:
- Septic lateral field repair
- Septic lateral field replacement
- System assessment
- Restoring proper drainage
-
Trenchless Sewer Repair and Replacement
Traditional sewer replacement means digging a trench across your entire yard. Trenchless methods avoid most of that disruption. Pipe bursting pulls new pipe through the old line while breaking apart the damaged one. Pipe lining creates a new pipe inside the existing one. Full Nelson evaluates your situation and recommends the approach that makes the most sense for your property.
Our services include:
- Trenchless sewer repair
- Trenchless sewer replacement
- Pipe bursting
- Pipe lining
- Installing new pipes

Water Heater Services Olathe
Hot water is essential for showers, laundry, and dishes. When your water heater stops working, the household feels it immediately. Full Nelson repairs and installs all types of water heaters. We help you weigh options, explain the differences between systems, and provide clear pricing before starting any work.
Gas Water Heater Repair and Replacement
Gas water heaters recover faster than electric models and cost less to operate in most areas. Common problems include pilot lights that won’t stay lit, faulty thermocouples, and tanks that rumble from sediment buildup. Full Nelson services all major gas water heater brands and installs new units sized correctly for your household’s hot water demand.

Electric Water Heater Repair and Replacement
Electric water heaters offer simple installation and work in homes without gas service. When heating elements fail or thermostats malfunction, water temperature becomes inconsistent or stops altogether. Tank corrosion eventually requires replacement. Full Nelson diagnoses electric water heater problems and completes repairs or replacement efficiently.
Tankless Water Heater Repair and Replacement
Tankless systems heat water as you use it, eliminating standby energy loss and providing hot water that never runs out. These units require different maintenance than tank models, including periodic flushing to remove mineral scale. Full Nelson services tankless water heaters from all manufacturers and installs new units for homeowners ready to make the switch.
Hybrid Water Heater Repair and Replacement
Hybrid water heaters pull heat from surrounding air to warm your water, using a fraction of the energy required by conventional electric tanks. They cost more upfront but deliver significant savings over their lifespan. Full Nelson installs and services hybrid systems, helping homeowners understand whether this technology fits their situation and budget.

Heating Services
Olathe
January temperatures in the Kansas City area drop into the single digits, and ice storms knock out power when you need heat most. A well-maintained furnace or heat pump keeps your family comfortable through the worst winter weather. Full Nelson added HVAC expertise in 2019 by acquiring a 25-year Kansas City heating and cooling company. That experience shows in every service call.

Furnace Repair, Installation, and Maintenance
Gas furnaces heat most Olathe homes. These systems run reliably for years but eventually develop problems: ignition failures, blower motors that quit, and heat exchangers that crack from thermal stress.

Our services include:
- Furnace repair & replacement
- Furnace installation
- Furnace maintenance
-
Heat Pump Repair, Installation, and Maintenance
Heat pumps move heat rather than generating it, delivering efficient heating and cooling from one system. Modern heat pumps work effectively even in cold weather.

We also install new systems sized for Olathe’s climate.
Our services include:
- Heat pump repair and replacement
- Heat pump installation
- Heat pump service

Our services include:

Mini Split Repair, Replacement, and Installation
Mini splits deliver heating and cooling to specific rooms without ductwork. They work well for additions, sunrooms, finished basements, and older homes that lack existing ducts. Each zone has its own thermostat, letting you condition only the spaces you use. Full Nelson installs mini split systems and services existing units when problems arise.
-
Filters, Dehumidifiers, UV Lights, and Indoor Air Quality
Humid summer air promotes mold growth and makes your home feel warmer than the thermostat indicates. Your air conditioning system removes some moisture, but whole-home dehumidifiers do a better job in our climate. Full Nelson also installs upgraded filtration and UV light systems that improve the air your family breathes all summer long.
-
Duct Services
Ductwork distributes conditioned air throughout your home. Leaks in duct joints waste energy and create uneven temperatures between rooms. Dust, pet dander, and allergens accumulate inside ducts over time. Full Nelson provides duct cleaning to remove debris and duct sealing to eliminate air loss and improve system efficiency.
- Power When You Need It
Generator Installation
Olathe
Olathe loses power during ice storms, thunderstorms, and high winds every year. Established neighborhoods with tall, mature trees like Havencroft and Forest Hills see outages more frequently. A standby generator starts automatically when the power fails, keeping your refrigerator, HVAC system, and lights running until utility crews restore service.
Whole-Home Standby Generators
- Whole-Home Standby Generators
- Automatic startup during power outages
- Keeps lights, HVAC, and appliances running
- Protects against storm-related outages
Full Nelson sizes generators based on your home’s electrical load and installs the complete system, including automatic transfer switch and fuel connection.
