Expert Heating Maintenance Services in Connecticut

In Connecticut, with its cold winters and substantial use of heating systems to keep homes and commercial buildings warm, preventative heater maintenance should ideally be carried out annually. The best time to schedule Connecticut preventative heater maintenance services is during the early fall, ahead of the heavy usage period. This annual check-up can allow our technicians to spot any potential issues and resolve them before they escalate into major complications. 

If your heating system is older or is in constant use, you might want to consider having it inspected more frequently. Systems that are over a decade old, or those that operate throughout the year due to being part of a combined heating and cooling system, might benefit from biannual maintenance visits. This can help in identifying wear and tear issues at an early stage, ensuring your system continues to operate efficiently.

Not sure how often your heater needs maintenance? We can assess its age and performance and advise how frequently you should schedule professional inspections.   Check out our blog articles on the importance of an annual tune up and the benefits of a service plan for your oil burner to learn more.

Urgent Heating System Repairs: Recognize the Warning Signs

Keeping on top of routine maintenance will help you avoid many common heating system issues or catch problems before they escalate. Regular maintenance is a preventative measure, but it does not eliminate the need for timely interventions if problems do arise.

There are certain signs that your heating system might require immediate professional attention, even if regular maintenance is being conducted, so do not wait to call Levco if you notice:

  • Unusual noises. If your heating system is making strange or unusually loud noises, it might indicate an underlying problem. Sounds such as banging, whining, or buzzing could be a sign of a mechanical issue that needs immediate attention.
  • Inconsistent heating. Your heating system should distribute heat evenly in your home or building. If you notice cold spots or rooms not heating properly, it may indicate an issue with your heating system's distribution capabilities.
  • Unexplained spikes in energy bills. If you notice a sudden increase in your energy bills without any significant change in your heating usage, your heating system might be operating inefficiently. 
  • Frequent Cycling. Your heating system should not be turning on and off frequently. This could indicate a major problem that needs to be addressed promptly.
  • Poor Air Quality. If you notice an increase in dust, dry air, or respiratory problems among the inhabitants, it may suggest that your heating system is not adequately filtering the air.

Comprehensive Preventative Maintenance for Your Heating System

At Levco, our technicians are highly skilled and trained to maintain a wide variety of heating systems. We service both propane-fired and oil-fired heating equipment, and our team has the expertise to conduct thorough and essential maintenance tailored to your specific heating system.

Our Connecticut preventative heater maintenance services include expert assistance with:

  • Boilers. Propane-fired and oil-fired boilers are complex systems, and their maintenance involves several key steps and checks to ensure they are functioning optimally and safely. A typical maintenance service begins with a thorough inspection of the boiler system. This includes examining the heat exchanger for cracks or defects, checking the burner and flame sensor, and assessing the condition of the ignition and safety controls. We will also inspect the vent system to ensure it is free of blockages that could affect performance or safety. Cleaning plays a crucial role in boiler maintenance. The combustion chamber, where the fuel is burned to produce heat, accumulates soot and other combustion byproducts over time. This accumulation can reduce the boiler's efficiency and even pose a fire hazard. Therefore, cleaning the combustion chamber is an essential part of maintenance. We also clean out the flue pipe to prevent blockages and ensure the safe venting of gases. Our technician may need to adjust the air-fuel mixture to ensure optimal combustion and efficiency. This might also involve adjusting the burner and pilot light. If any parts are found to be faulty or worn out, such as the thermostat or the valves, we can recommend and complete replacements. Finally, we conduct a performance check to ensure the boiler is operating correctly. This involves checking the boiler's temperature and pressure and running the boiler to observe its operation. We will also do a final check for any leaks in the gas lines, seals, or valves. If your boiler uses oil, the oil filter will be checked and replaced if necessary.


  • Furnaces. When we inspect your propane-fired or oil-fired furnace, we meticulously assess all components, including the burners, heat exchanger, blower motor, ignition system, and safety controls. Our technicians will look for indicators of wear and tear, corrosion, leaks, or any signs of malfunctioning that could potentially disrupt the furnace’s operation or compromise its safety. We will clean the combustion chamber thoroughly as well as other parts like the blower assembly, flue pipe, and heat exchanger. Then, we will evaluate whether any adjustments or replacements are necessary. For example, we may adjust the belt tension for better operation of the blower motor. If any parts, such as filters, valves, or the thermostat, are found to be worn out or faulty, they will be replaced to prevent potential operational issues. Like boilers, we end with a comprehensive performance check that ensures that the furnace is operating efficiently and safely after all the cleaning, adjustments, and replacements. Our technicians will check the furnace's temperature and pressure, monitor its performance, and look out for any gas leaks in the lines, seals, and valves. In oil-fired furnaces, we will also assess whether the oil filter needs to be replaced. 


  • Hot water heaters. When conducting preventative maintenance, our technicians will examine the water heater for leaks, corrosion, or other signs of wear and tear that could compromise its function or safety. We will also check the drain valve to ensure it is operating correctly and inspect the pressure relief valve to ensure it can properly maintain the water heater's pressure. Then, we will drain and flush out the tank to remove any sediment buildup. This sediment can accumulate over time and can decrease your water heater's efficiency, increase energy costs, and even cause your water heater to fail prematurely. Our technicians will also inspect the heating element or gas burner, clean it as required, and ensure it is in good working order. After cleaning, we will evaluate the need for adjustments or replacements of components. This could involve adjusting the temperature settings for optimal performance or replacing worn-out anode rods, which help protect your water heater from corrosion. If the thermostat shows signs of malfunction, it might need to be replaced to ensure the water is heated at the right temperature.


  • Pool heaters. Preventative pool heater maintenance starts with a visual inspection. Among other things, our technicians will check the exterior for rust or corrosion, which could indicate water leaks, and examine any visible wiring for signs of burning or fraying. Next, the technician will clean various components of the pool heater. Over time, despite the use of pool chemicals, mineral deposits can build up inside the heater, reducing its efficiency. We generally use a specially formulated solution to clean these deposits from the heat exchanger. Our technicians will also clean the burner assembly to remove any debris or soot, ensuring the pilot light or ignition system operates correctly. If your pool heater uses combustion for heating, we may need to adjust the air-gas mixture for optimal performance. This process may involve tuning the burners or checking the pilot light. We will also inspect the thermostat and replace it if necessary to ensure the pool water is heated to the desired temperature.
