Boiler Repair in De Soto, MO
A malfunctioning boiler can quickly turn a comfortable home into a cold and unwelcoming space. When your boiler isn't working correctly, you need fast, effective repair services from professionals you can trust. In De Soto, residents and businesses can rely on Hely Heating and Air Conditioning for prompt and accurate Boiler Repair.
Common signs that your boiler may need repair include:
- No Heat or Insufficient Heat: The most obvious sign of a problem. This could be due to issues with the pilot light, thermostat, circulation pump, or other internal components.
- Strange Noises: Gurgling, bubbling, banging (often called "kettling"), or hissing sounds can indicate trapped air, mineral buildup, or pressure issues within the system.
- Leaking Water: Leaks around the boiler unit or piping can point to seal failures, corroded components, or pressure problems.
- Pilot Light Issues: If your pilot light keeps going out, there might be a problem with the thermocouple or gas supply.
- Low Boiler Pressure: Many boilers operate within a specific pressure range. If the pressure drops too low, the system may shut down.
- Radiators Not Heating Up: This could indicate issues with the circulation pump, air trapped in the system, or thermostat problems.

Boiler Installation & Replacement in De Soto, MO
Whether you're building a new home, replacing an aging, inefficient system, or switching heating sources, professional Boiler Installation is crucial for optimal performance, efficiency, and safety. Hely Heating and Air Conditioning provides expert boiler installation and Boiler Replacement services throughout De Soto, MO.
Deciding whether to repair or replace your boiler can be challenging. Here are some signs it might be time to consider a new installation:
- Age: Boilers typically have a lifespan of 15-20 years. If your boiler is approaching or exceeds this age and requires frequent, costly repairs, replacement is often a more economical long-term solution.
- Frequent Breakdowns: If your boiler needs repairs every heating season or multiple times a season, the cumulative cost can outweigh the investment in a new, more reliable unit.
- Decreased Efficiency: Older boilers, especially those with lower AFUE ratings (Annual Fuel Utilization Efficiency), are significantly less efficient than modern systems. A substantial increase in energy bills may indicate your boiler is losing efficiency.
- Inconsistent Heating: Cold spots or uneven heating throughout your property could signal that your boiler is no longer capable of effectively distributing heat.
- Safety Concerns: Cracks in the heat exchanger or other serious issues can pose safety risks like carbon monoxide leaks.
When considering a new boiler, efficiency is a key factor. The AFUE rating indicates how efficiently a furnace or boiler converts fuel into usable heat over a year. For example, an 80% AFUE boiler means that 80% of the fuel energy is used for heating, while the remaining 20% is lost through the chimney or other inefficiencies. Modern high-efficiency condensing boilers can achieve AFUE ratings of 90% or higher, leading to significant energy savings and lower utility bills over time.
We specialize in the installation of gas boilers, which are prevalent in the De Soto area. Our partnership with leading manufacturers like Goodman and Daikin allows us to offer reliable, high-quality systems designed for lasting performance. We guide you through selecting the right boiler type and size for your property's specific needs and ensure a precise, compliant installation according to manufacturer specifications and local codes. A properly installed boiler not only provides consistent comfort but also operates safely and efficiently for years to come.
Boiler Maintenance in De Soto, MO
Routine Boiler Maintenance is not just recommended; it's essential for keeping your heating system running safely and efficiently throughout the cold months in De Soto. Just like regular oil changes for your car, annual boiler tune-ups can prevent costly breakdowns, improve energy efficiency, extend the lifespan of your equipment, and ensure safe operation.
Our comprehensive boiler maintenance service includes a detailed inspection and cleaning of key components, such as:
- Checking and cleaning the burner assembly
- Inspecting the heat exchanger for cracks or corrosion
- Checking the igniter or pilot light
- Testing safety controls and valves
- Verifying proper system pressure
- Inspecting the expansion tank
- Checking for leaks in pipes and fittings
- Flushing the system if necessary (depending on water quality and system type)
- Monitoring exhaust flue integrity
- Checking the thermostat calibration
Regular maintenance helps identify potential problems before they lead to a complete system failure. It also ensures your boiler is operating at its peak efficiency, which can significantly reduce your energy bills. Furthermore, it helps maintain healthy indoor air quality by ensuring proper combustion and venting.
To make maintaining your boiler simple and cost-effective, we offer a Maintenance Plan that includes annual tune-ups and other benefits. Enrolling in a plan provides peace of mind, knowing your heating system is regularly inspected and cared for by professionals.
