Oil and Gas Furnace Cleaning, What is the Difference?2024-09-02T07:54:56-04:00

Cleaning Stages of Oil and Gas Furnace

  1. Oil and Gas Furnace Differences: Cleaning oil and gas furnaces involves distinct processes. For oil furnaces, the oil burner requires special attention—it’s essential to clean and tune the oil burner to ensure efficient operation. This step is unique to oil furnaces and is not required for gas furnaces.
  2. Blower Motor and Filters: Both oil and gas furnaces need regular maintenance of their blower motor compartments. This includes thoroughly cleaning the blower motor and replacing the air filters. Keeping these components clean ensures that the furnace operates efficiently, reduces wear and tear on the system, and maintains good indoor air quality.
  3. Flue Pipe and Exhaust Chambers: Another critical step in maintaining both oil and gas furnaces is the cleaning and inspection of the flue pipe and exhaust chambers. These components must be vacuumed out to remove soot, debris, and any potential blockages. Inspecting these areas is crucial for safe operation, as any obstruction could lead to dangerous conditions such as carbon monoxide buildup.
  4. Oil Burner Cleaning and Tuning: For oil furnaces, the cleaning and tuning of the oil burner involve several specific tasks:
    • Changing Filters: The oil tank filter and the pump screen filter are replaced to ensure a clean supply of oil to the burner.
    • Drawer Assembly Maintenance: The drawer assembly, which houses the oil burner components, is cleaned and adjusted. During this process, the furnace electrodes and the nozzle are inspected and replaced if necessary.
    • Checking Oil Pressure: The oil pressure is checked and adjusted to ensure it is within the manufacturer’s recommended settings. Proper pressure is crucial for efficient combustion.
  5. System Setup and Combustion Analysis: After the burner has been cleaned and tuned, the entire system is set up according to the manufacturer’s specifications found in the burner manual. The furnace is then fired up, and a combustion analyzer is used to measure and adjust the oil-burning parameters. This step ensures the furnace operates at peak efficiency and within safe limits.
  6. Report and Smoke Test: A printout report is generated from the combustion analyzer, providing a detailed overview of the system’s performance and any adjustments made. Additionally, a smoke test is conducted during the burn to ensure that the combustion process is clean and efficient. This test checks for the presence of soot or other combustion byproducts, which could indicate incomplete combustion or other issues.

This comprehensive approach to cleaning and maintaining oil and gas furnaces ensures their longevity, efficiency, and safety, helping to prevent breakdowns and ensuring optimal performance throughout the heating season.

Why do I need to Winterize my Home?2019-08-27T21:45:19-04:00

Fall is the best time for winterizing your Home.

1- One of the simplest things a homeowner can do to protect their real estate investment is to shut off the main water supply if they are going to be out of the their house for any length of time.
Water does the most damage to any piece of property whether it is your primary home or a second home. One of the simplest things to do is to winterize the house or a property you might not be in through the winter months or you will visit in frequently through winter.
2- If you have a hot water heating system you can Glycol the system to help prevent baseboard and heating coils from freezing.
Winterizing Glycols are not harmful to the environment and or to your plumbing system.
3- If you are going away for a weekend or longer get into the habit of shutting down the main water supply.
4- After closing off the main water supply drain down the system to the lowest point.
This can be a basement bathroom or slop sink or even drawing water off the bottom of the water heater.

✅ Avoid pouring grease, coffee grounds, and non-flushable items down your drains. Scheduling professional drain cleaning once a year helps prevent backups.
