There is no more disappointing thing than an investment you took time to consider yet ended up not doing its purpose. It may be a car, a home entertainment center, or even a furnace that is supposedly keeping you warm.
Often in the event of a furnace breakdown, most homeowners resort to calling HVAC services due to panic. Customers pay for a diagnostic service fee and an emergency service charge if they feel like they need immediate help. Sometimes, it’s as simple as lousy thermostat batteries or a clogged air filter–things you can troubleshoot on your own.
Check your thermostat
The thermostat, being the center of your heating system, maybe the culprit of sudden discomfort you are feeling.
- If it appears that your furnace doesn’t produce any heat, check the battery in the thermostat. In several models, replacing the batteries may do the trick.
- When the blower fan doesn’t shut off or the furnace cycles between on and off too frequently, check the thermostat settings. The fan setting should be on auto, and if not, the fan will run continuously.
- If the furnace doesn’t produce enough heat, check the thermostat’s setting to make sure it’s in heat mode.
- Check the temperature to make sure it’s on a level higher than the current room temperature; ideally, five degrees higher and then feel the air if there are changes or if the furnace kicks in.
- Make sure that the program is displaying the correct date and time.
Ensure the gas valve is open
A furnace gas valve is a component of your furnace’s fuel system.
- The gas valve can switch from open to close and vice versa, which allows the movement of fuel to the pilot light and burners.
- While the component itself is relatively simple, a furnace gas valve is a crucial part of your HVAC system.
- If you are the one at task to do it, locate the handle that should be parallel with the gas pipe and turn it on.
Look for leaky duct
High energy bills and a dusty environment are some of the indications that you have leaky air ducts. Unless your unit has wholly stopped providing your home with warm or cold air, one of the prominent places to start looking for the issue is in your air ducts. Here’s how!
- The first thing to carry out is to look for visible tears in your air ducts. You can mark these found spots with a pencil so that you can get back and fix them once upon finishing checking your whole system.
- Turn your HVAC unit on full blast. If there is a more generous amount of air flowing through, it will be easier for you to find air duct leaks.
- Duct joints are spots where two air ducts connect are familiar places for leaks to happen. You can place your hand near these joints, and if you feel air coming out, you know that there’s a leak.
- Seal up the leaks you’ve found so far by wrapping the air duct where the is a hole with foil-faced tape or duct tape – at least not as a permanent fix. There is another method, which is applying mastic to the leak.
Change the furnace’s air filter
A clean air filter appears white or off white, but eventually, with dust and dirt, it will look darker in color.
- However, the inner layers of filter paper inside the air filter might hold dust and debris that are not visible even in bright light.
- If this is the case with your air filter, we recommend that you get them checked every one to three months and replace them as necessary.
- This practice will help you have a comfortable warmth and increases the life span of your furnace. Remember that when changing your filter, always shut the switch on it and turn the thermostat off mode.
Flush out drain lines
- Due to the cooling process’s moisture combined with airborne contaminants, mold and algae can surface in the drip pan.
- The growth can clog the drip pan and even rinse into the condensate drain lines, causing a clog in the piping.
- If you can spot any of the tell-tale signs of a condensate line or drip pan clog, you can clean them with caution by following these steps:
- Shut off power to your HVAC system.
- Please turn it off at the thermostat as well as the breaker.
- Locate the drip pan, which is typically underneath the interior air handling unit.
- You need to remove a sheet metal panel to have access to it. If there is water in the drip pan, a clog is likely to present in the line.
- Using a wet or dry vacuum or rags, remove all water from the drip pan. Remove the drip pan and clean away all mold, algae, and contamination with a mild soap.
