Expert Boiler Installation in Knoxville
Sometimes repairing a boiler isn’t the most practical solution. If your system is outdated, breaking down frequently, or requiring costly repairs, installing a new boiler may be the smarter choice.
When we handle a new boiler installation, we consider every factor to deliver optimal performance and efficiency:
- The size and layout of your home or business
- The condition of insulation and existing piping
- Your radiator setup and hot water usage
Our goal is to match you with a boiler that meets your heating needs without overworking the system or wasting energy. During installation, we take care to protect your floors and living spaces, remove your old unit safely, and install your new boiler with precision. After testing, we walk you through thermostat operation, system performance, and ongoing maintenance tips.
If you’re unsure whether to repair or replace your boiler, we provide a clear comparison of costs, system age, and expected reliability so you can make an informed decision without any pressure.
Boiler Replacement Services
Older boilers often lack modern efficiency and safety features, leading to higher utility bills and more frequent problems. Upgrading to a new system can:
- Lower energy costs with advanced, ENERGY STAR® certified models
- Eliminate the hassle of a pilot light
- Improve safety with modern controls and sensors
- Provide consistent warmth even in the coldest months
We’ll guide you in selecting a boiler that fits your home or business size, insulation, and hot water requirements, ensuring long-term comfort and savings.
Comprehensive Boiler Repair in Knoxville
Our team handles a wide range of boiler repair needs for both hot water and steam systems. We troubleshoot efficiently, and for complex issues, we deliver expert solutions to get your system running safely and reliably.
Common boiler problems we address include:
- Thermostat Issues: Faulty or outdated thermostats can cause uneven temperatures. We repair or upgrade to programmable models for precise control.
- No Heat or Uneven Heating: We inspect all components, water levels, and settings to restore consistent warmth.
- Leaks and Water Damage: We locate and repair leaks from worn seals, corroded parts, or broken components before they worsen.
- Unusual Noises: Banging, gurgling, or whistling often indicates trapped air, mineral buildup, or failing components, that's why we correct the issue for safe operation.
- Pilot Light or Ignition Problems: We repair thermocouples, clean deposits, and restore reliable startup.
- Low Water Pressure or Frequent Shutdowns: We diagnose the cause and adjust valves, pumps, and circulation to maintain consistent performance.
- Cold or Uneven Radiators: Sludge and trapped air reduce efficiency; we flush and bleed the system to restore even heat.
- Frozen Condensate Pipes: We safely thaw frozen pipes and implement measures to prevent future freezes.
Many of these issues result from skipped maintenance or aging equipment. That’s why we also offer regular boiler service plans to catch problems early, extend your system’s lifespan, and keep your home comfortable while managing energy costs.

It’s common for your heating and cooling equipment to make a little noise. However, hearing odd or loud noises could mean there’s an electrical problem or trouble with the blower fan or capacitor. If not fixed, there can be serious (or expensive) consequences later on.

A popping disturbance is a common sign of an insufficient duct design. This occurs when there’s more airflow than your ductwork can manage.
Troubles with your ductwork can lead to other ventilation and air quality troubles, such as:
- Significant noise
- Greater energy needs
- Early system malfunction
- Irregular heating and cooling
- Broken AC compressor in the summer
- Too hot furnace or heat pump in the winter
- Mold growth inside ducts
Call a qualified company in the U.S like R & M Climate Control Service Experts to examine your home’s ventilation system. We can offer suggestions for duct repair or installation.
