Furnace Maintenance in Covina, CA

A homeowner from Covina, CA, called Pioneers Heating and Air for furnace maintenance. Their furnace had not been serviced in over a year and had been making hissing noises for months. We scheduled them for the long-overdue tune-up and inspected their furnace with a 21-point checklist. Upon inspection, our technician noted that the furnace fan belt had loosened and needed an alignment and tension tightening. After checking that everything worked well, we taught the homeowner the basic maintenance steps they could take on their own to keep their furnace functioning properly.

If you are anything like this homeowner, you probably have not had your furnace unit serviced in a while. Most often, routine upkeep is something many homeowners take for granted. However, it is essential to remember that your furnace needs to be maintained. If you do not, you could endanger yourself at the risk of a fire or other severe issues. Meanwhile, regular tune-ups can prevent breakdowns, saving you money and hassle down the road. 

What Is Done During a Furnace Tune-Up?

Some of the best practices that HVAC technicians follow include:

Checking the venting system for obstructions and the right slope

Checking the venting system ensures there is no risk of carbon monoxide poisoning in the home. This step necessitates a visual inspection, draft inspection, and combustion analysis.

Checking the heat exchanger for damage or wear indicators

If any problems are discovered, the technician will likely recommend having the heat exchanger fixed or replaced immediately to avoid potential fire hazards.

Testing all safety switches on the furnace

The technician will test all safety switches (roll-outs, high limits, and others) on the furnace to ensure that they are all in good working order and will turn the appliance off if it overheats.

Checking the burners

The technician should check the ignition and flame on the furnace burners. Almost completely blue flames indicate safe and efficient combustion.

Checking the flame sensor and ignition device

It is essential to check the flame sensor and the ignition component (ignitor, spark, thermocouple, and others) for cleanliness and accurate readings.

Checking the combustion blower

The technician will check if there are any bearing noises, amp draw, and blockages on the combustion blower (the device that propels your combustion air outside).

Checking the main blower

The technician will check the capacitor readings, amp draws, and cleanliness of the main blower. It may also include checking for a broken or faulty blower motor belt, lubrication, or tightening the motor mounts.

Cleaning the drainage system

Cleanup and inspection of the drainage system are necessary. Only furnaces that are 90% or more efficient will require this procedure.

Checking the electrical wirings

It is necessary to inspect all wiring for corrosion and the right connections. Loose connections can cause equipment failure or fires.

Performing a temperature rise

A temperature rise should be used (and, if necessary, a static pressure test) to measure sufficient airflow.

Cleaning or changing the filter

There are two types of furnace filters: disposable (with cardboard frames) and permanent (with fiberglass or metal framing). The technician will check the filter for any dust or debris that could clog, then clean or change it if needed.
