When Plumbing or HVAC Problems Disrupt Your Day

A burst pipe at 2 a.m., a furnace that quits on the coldest night of the year, or an air conditioner that stops cooling during a heat wave can turn an ordinary day into a stressful emergency. When these problems happen, you need a team that answers the phone, arrives prepared, and fixes the issue correctly the first time. That is exactly what we deliver at Larry's Plumbing, Heating and Cooling.

We are a family owned full service plumbing, heating, and cooling business that has been in business since 1982. Over these decades, we have built our reputation on honest work, technical skill, and a genuine commitment to the comfort and safety of the homes and businesses we serve across Vermillion and Yankton, SD. When you call us, you reach people who treat your property with the same care we would give our own.

Comprehensive Plumbing Services

Your plumbing system works quietly behind walls and under floors until something goes wrong. We handle the full range of residential and commercial plumbing needs, from small leaks to complete repiping projects.

Our plumbing work covers a wide spectrum of situations that homeowners and property managers face every day. For water heater service, we install, repair, and maintain both tank and tankless units, including gas and electric models. We also handle fixture installation, fitting new faucets, toilets, garbage disposals, and sump pumps to modern standards. When pipes are corroded, frozen, or broken, we repair or replace them and upgrade outdated systems.

Because water damage grows worse by the minute, we respond quickly to protect your property. We service all makes and models, so you do not need to worry about whether your existing equipment matches a specific brand. Our goal is a lasting repair, not a temporary patch.

Heating Systems You Can Rely On

A dependable heating system is essential during the cold months. We install, repair, and maintain furnaces, boilers, and heat pumps to keep your indoor spaces warm and safe. Modern heating equipment involves careful measurement of airflow, gas pressure, and combustion efficiency, and our technicians are trained to test each of these factors during a service visit. Proper calibration keeps your energy use down and extends the life of your equipment.

Seasonal maintenance is one of the best steps you can take to avoid a breakdown. When we perform a heating tune-up, we follow a clear process from start to finish:

  1. Inspection: We examine the heat exchanger, burners, and electrical connections for wear or damage.
  2. Cleaning: We remove dust and debris that reduce efficiency and cause strain on components.
  3. Testing: We verify safe operation, correct thermostat readings, and measure carbon monoxide levels.
  4. Reporting: We explain our findings and recommend any repairs before they become emergencies.

If your system is beyond repair, we help you choose a replacement that fits the size of your space and your budget. We offer free estimates and financing, so you can make an informed decision without pressure.

Cooling and Air Conditioning

When summer temperatures climb, a properly working air conditioner protects your comfort and health. We install and service central air systems, ductless mini-split units, and heat pumps that both cool and heat. Correct sizing is critical: an oversized unit cycles on and off too often, while an undersized unit runs constantly and wears out early. We perform load calculations to match the equipment to the specific demands of your building.

Regular cooling maintenance keeps your system efficient and reliable through the hottest days. We check refrigerant charge, clean condenser and evaporator coils, inspect electrical components, and confirm that airflow meets specification. These steps help prevent the sudden failures that so often happen when a system is pushed to its limit. As with our heating work, we service all makes and models, giving you flexibility no matter what equipment you already own.

Why Homeowners and Businesses Choose Us

Trust is earned through consistent, quality work, and we have earned it since 1982. As a family owned company, we answer to our neighbors and our community, not to a distant corporate office. We offer 24/7 emergency service because plumbing and HVAC failures do not wait for convenient hours.

Throughout Vermillion and Yankton, SD, property owners rely on us for prompt response, transparent recommendations, and craftsmanship that stands the test of time. Whether you need a routine tune-up, an urgent repair, or a full system installation, Larry's Plumbing, Heating and Cooling is ready to help.
