HVAC systems are designed to last for decades, but they can only do so much. That’s why it’s important that you get your HVAC system inspected and maintained regularly by a professional.

A heating, ventilation and air conditioning (HVAC) system is the heart of your home. HVAC Company Cambridge MN

An HVAC system is the heart of your home. It keeps you comfortable by controlling the temperature and humidity levels in your home, as well as providing airflow through the ducts. Your HVAC system includes:

  • A furnace
  • A condenser/evaporator coil (heat exchanger)
  • Air ducts that lead from the heat exchanger to vents throughout your home

It’s designed to last, but a bit of TLC can help it work even better.

Your heating, ventilation and air conditioning (HVAC) system is designed to last. But a bit of TLC can help it work even better.

The components of your HVAC system include:

  • A furnace or air handler (heating unit) that distributes warm air throughout the house.
  • An evaporator coil or cooling coil inside the furnace, which cools the home’s indoor air and sends it through the ductwork to each room. The condenser removes heat from outside air before it enters into the evaporator coil to keep things running smoothly year-round, whether there’s snow on the roof during winter months or leaves falling in autumn. And a filter keeps dirt and other particles from entering into your home’s HVAC system so that you can breathe easier every day when you turn on your thermostat!

Regular maintenance can prevent unexpected problems.

Regular maintenance is crucial for keeping your heating and air conditioning system running efficiently. By having a professional technician check the components of your HVAC system, you can discover potential problems before they become more serious. A simple checkup from an HVAC technician can help you avoid costly repairs down the road by identifying issues early on.

If you wait too long between servicing appointments, it’s possible for problems to develop that could lead to an emergency situation—and those aren’t cheap! The longer an issue goes without being addressed, the higher the likelihood that it will result in expensive repair bills down the road. If you are looking forward to saving money on energy costs this year, regular maintenance should be at the top of your list so that any small issues can be detected before they get out of control and cause more damage than necessary. Reach out to your local HVAC Company Cambridge MNTrue North Heating and Air to schedule an appointment for your regular HVAC maintenance.

Get a tune-up in the fall. HVAC Company Cambridge MN

When winter comes around, you’ll want to be sure that your heater is working at its best. Get a tune-up in the fall before the heating season begins to keep your furnace operating at peak efficiency throughout the winter months and to increase its lifespan.

  • A tune-up will ensure that your HVAC system is running efficiently and safely by checking for problems such as dirty filters or clogged vents.
  • A qualified technician will also ensure that all electrical components are working properly in order to protect against fire hazards like electric shocks or fires caused by faulty wiring within an electrical circuit for an HVAC unit designed with multiple circuits (i.e., one fan motor may have two separate circuits going into it).

Check the thermostat batteries. HVAC Company Cambridge MN

Check the thermostat batteries. If you have a digital thermostat, make sure the batteries are fresh. If they’re not, replace them with new ones and make sure they are installed correctly (positive side up). Then check the settings on your thermostat to ensure it is not set to a lower temperature than it should be. This can happen if there is an error in how your system was programmed or from improper wiring by someone who did not know what they were doing when adding new equipment such as a humidifier or dehumidifier.

Check the filters. HVAC Company Cambridge MN

Filters are an important part of the HVAC system because they keep dust and other particles from clogging up your equipment, which can lead to expensive repairs or even complete failure of your equipment. You should check your filter monthly during heating season and vacuum them if needed, but replacing them is usually only necessary every two to three months for most people with central air conditioning systems. If you have a high efficiency furnace, however, it may be necessary for you to replace your filter much more frequently than that (consider having an electrician install an automatic shut-off switch so that when it reaches a certain level of dirtiness, the furnace shuts itself off).

Look for leaks and cracks in your ductwork.

To prevent expensive problems with your heating and cooling system, make sure you’re keeping up on your HVAC maintenance. The first thing to check for is signs of leaks or cracks in the ductwork. Look for missing or loose screws and nails, as well as bulges or sags in the ductwork. If you come across any issues, call a professional to get them fixed before they become more serious issues.

Make sure the condensate drain isn’t clogged.

The condensate drain line is a PVC pipe that runs from your air conditioner, through the wall and down to the ground. Condensation forms on the tubes of an air conditioner, which then drips into this pipe until it reaches the ground where it can evaporate. If this tube becomes clogged or frozen, it could cause water damage inside your home or even cause mold growth within your HVAC system. Make sure you check for signs of a clog in this tube every time you clean or maintain your air conditioning system so that you can keep your home safe and dry!

Clean the evaporator coil.

The evaporator coil is the part of your HVAC unit that gets hot and turns water into ice, which cools air. Dirt, dust and other particles get stuck in this area (usually over time), making it harder for your system to cool itself down. Over time, a clogged evaporator coil will cause your AC unit to use more energy than necessary because it can’t properly expel heat from inside your home.

You can clean this part yourself by opening up the cover on top of it with an Allen wrench or screwdriver; just make sure not to touch any electrical wires when doing so! If you don’t see any visible grime or buildup, there’s no need for further maintenance—just close up the cover again and wait until next month before checking again.

Check the air conditioner compressor.

  • Check the air conditioner compressor’s leaks. A properly operating AC will have a very small amount of refrigerant gas escaping from it, but if you notice more than a drop or two leaking out during operation, this is an indication that your unit needs to be serviced by an HVAC professional.
  • Check the air conditioner compressor for damage. If your AC isn’t blowing cool air anymore or doesn’t seem to be running as efficiently as it used to, there may be something wrong with its components—and these can often lead to larger problems down the road if left untreated. An HVAC Company Cambridge MN will carefully inspect all parts of your system so that you can make sure everything is working as it should (and nothing has been damaged).
  • Check the air conditioner compressor for proper operation and lubrication. Not only does poor lubrication increase wear on moving parts within an AC system; it also makes them less efficient at transferring heat from inside your home into outside air—which means higher energy bills for you! Your professional HVAC Company Cambridge MN will ensure that any needed oiling is done correctly so that your central heating/cooling system works efficiently throughout its lifespan.

Changing or cleaning your furnace filter before each heating season begins to keep your furnace operating at peak efficiency throughout the winter months and to increase its lifespan. A dirty filter slows down airflow and makes the system work harder to keep you warm or cool, resulting in inefficient operation, increased energy costs and possible damage to the system components.

To change your filter:

  • Turn off power to the furnace at the circuit breaker panel. If there is no circuit breaker labeled “furnace” or similar, follow instructions below for shutting down electric heaters or air conditioning units.
  • Open a window in an adjacent room where you can hear whether the motor kicks on when you switch it back on (if it does not turn off automatically).


If you have a residential HVAC system, it’s important to keep on top of regular maintenance.
