What heating and air conditioning problems can you solve on your own?

Your heating and air conditioning equipment doesn't always act as it should. It's easy to ignore until something goes wrong. Then? It seems like nothing but an expert's opinion will do. There are a few exceptions to this rule you should know in case your HVAC system goes down. There may be actions you can take to get things back up and running on your own without any wait.

AC Is Running, But There’s No Cool Air

One of the most common HVAC problems is a lack of conditioned air. The heater turns on, but it’s not warm. The AC is blowing, but it’s not cold. This is one of the most frustrating problems. It might also be easy to fix.

First, change your air filter. A dirty filter will circulate contaminants throughout your home and allow bits of debris to damage your system. It will also prevent contaminated air from filling your house. Be sure to change those filters on a tight schedule, or enroll in a maintenance plan so someone else will do it for you.

If your filter is clear, it’s time to check your outdoor unit. Grass, weeds and other debris can crowd your AC and block airflow. Does it look dirty? You might have to call a technician to give it a good cleaning.

The System Won’t Turn on at All

Sometimes homeowners assume when an HVAC system isn't working it's in need of major repair. Before you resign yourself to using fans while you save for repairs, take a look at a few common causes.

First, be sure there is electricity running to the unit. You might need to reset the breakers or change out fuses. You might have to change the batteries in your thermostat. Power issues are the number one reason behind service calls. Homeowners can fix many of these issues on their own.

Second, make sure air is running to the unit. Pipes leading from outdoors to a natural gas HVAC setup deliver the air needed to fuel the pilot. Sometimes these pipes get blocked by leaves, bugs or other debris. Clear out connection points and attempt a system reset. You can find the directions inside the door to the HVAC cabinet.

Warnings You Can’t Ignore

While troubleshooting, you might run into a few signs of serious problems. If you experience the following, shut off your system and call a professional immediately:

  • The system repeatedly blows a fuse
  • There is a loud bang before the system turns on
  • You hear the sound of metal on metal

All three situations could lead to a fire, explosion or serious damage to your HVAC system. It's best to turn things off and wait for the help of a professional.
