Furnace Repair and Replacement Eden Prairie MN

With winter around the corner, it is essential to make sure that your business is ready for low temperatures. Checking your commercial property’s heating system is the most important thing to do as cold weather approaches. A well-functioning furnace will provide your staff and clients a safe and warm environment all winter. Here are seven common furnace repairs and their solutions:

Your Business Property Isn’t Heating. 

One of the most usual reasons why furnaces fail to produce heat are clogged filters. This can be a pain when attempting furnace repairs on your own, but we hope to lend a hand with a few tips.

Besides purifying the Air, air filters keep the internal engine of your heating system working properly. A dirty filter can damage your HVAC’s performance by decreasing its airflow, overheating the furnace, and increasing the system’s energy use. 

Try fixing this problem with these simple steps:

Turn Your HVAC off

Make sure that no air is coming out of your Furnace.

Locate the Filter

The filter compartment looks like a grate, and it is usually located between the return air duct and the air handler.

Check the Filter  

If the filter is noticeably gray and has a cloud of dust in its duct side, then it is time to change it. Also, check the dimensions of the filter you are replacing, so you buy one that fits perfectly with your Furnace.

Replace the Filter

Remove your old furnace filter and insert the new one into the filter compartment according to the direction that your filter points indicate. 

Furnace’s Controls Aren’t Working Properly.

If you have problems controlling the temperature levels of your Furnace, it is probably due to a thermostat problem. In case this happens, you should try these alternatives in the following order to help with your furnace repairs: 

  1. Check that the thermostat is set to the right temperature. It should be five degrees higher than the room temperature.
  2. Change the batteries on the thermostat. 
  3. Reset the thermostat following your manufacturer’s instructions.
  4. Open the thermostat to make sure that nothing is clogging it.

If none of these options work, then you should probably get a new thermostat.

The Furnace Won’t Turn On

If the thermostat isn’t the problem, check your breaker panel to see that none of the circuit breakers or power switches are turned off accidentally if they are ON, test breakers by manually flipping them back and forth.

 If this doesn’t work, it is possible that one of the breakers was tripped or blown. In that case, have a qualified electrical professional examine the wiring. Always make sure that you are not standing in water while revising the breaker panel.

The Furnace Isn’t Blowing Air 

This problem is usually related to the Furnace’s blower motor. Look at the inspection window of the Furnace to ensure that the blower isn’t obstructed with debris. Typically, furnaces have a light that indicates the blower system status; if the light is green, your blower motor is okay. If it’s red, then you should ask for professional assistance. An HVAC expert should examine the control board, transformer, and thermostat.

Certain Parts of the Space Aren’t Heating 

Walk around your place to check that nothing is obstructing your vents’ airflow. Ensure that all the vents are clean and that they are not being blocked by rugs, curtains, or pieces of furniture. 

The Furnace is Short Cycling 

Rapid cycling occurs when the Furnace turns up and then quickly turns off. These are some of the problems that can cause short cycling to occur:

Oversized Unit 

Your Furnace might be too large for the space you want to warm up.

 Thermostat Placement

Make sure that your thermostat is placed in a location where it reads the temperature properly. The thermostat should be located away from direct sunlight and heat-producing appliances.

Worn-out Filter

Check if your air filter is too old or if a clogged filter is restricting its airway.

If none of the alternatives above solve the problem, then you should require professional assistance.

Furnace Fan Isn’t Working Properly.

Unplug the heating unit and clean the Fan of any dust that can prevent it from running properly. If this doesn’t solve the issue, check the connection of the internal wires. If none of these options work, you need to call an HVAC expert to install a new fan’s motor. 

Your Safety

Remember that fixing your Furnace’s problems yourself is a good idea only if you have the right skills to do it. If your heating system’s problems are above your skill level, trying to fix them could be dangerous and more high-priced in the long run.
