Checking air filters is a necessary step of HVAC system maintenance

Is Your HVAC System a Home for Pests?

The topic of frequent maintenance has been a common one, and we have listed numerous risks connected to a poorly kept HVAC system, and various benefits from DIY as well as professional maintenance check-up. Dirt and debris are mentioned often as the cause of many HVAC problems, but who is actually to blame for different debris finding their way into our system? Besides the elements we cannot control, different small animals cause damages that could have been easily avoided by frequent cleaning and caring for the system as a whole.

What Pests Do to Your System

  • They destroy components within the units and increase the costs of repair and replacement.
  • Larger pests build nests in your system which significantly increases the risk of fire, power loss, and dangerous power surges.
  • The debris animals create (fur, uneaten food, dead animals) change the quality of the air inside your home.
  • They block your system and decrease the efficiency of your unit.
  • They trigger allergies and different respiratory conditions.

Most Common Pests Found in Indoor and Outdoor Units

  • Bugs – spiders and cockroaches are the most common bugs infesting our homes, and even though they rarely cause concrete damage to the system, they carry diseases and can be poisonous.
  • Mice and rats – these critters love to chew through various materials, including refrigerant lines and other HVAC components, damaging the system. Their bodily fluids and scratching create additional damage.
  • Snakes – not a welcome sight, snakes are often drawn to the heat of the condenser coils and are often unfortunate victims of fan blades, damaging the external unit components in the process.
  • Squirrels and raccoons – Besides chewing through components, squirrels and raccoons make large holes in the walls of your home, causing draughts and making it difficult to maintain your chosen temperature.

Air Conditioning Repair

Avoid Power Loss Due to HVAC Fails

Our air conditioning system can be one of the major causes why our circuit breaker trips, especially during warmer months when we need the cooling power of our HVAC system to make our everyday life more enjoyable. If you suspect that your air conditioner is to blame for your electricity going down, check these common culprits that might be overheating the system!

Dirty Filters

If you have dirty air filters, chances are your air conditioner is draining too much energy while working hard to pull air through the filters. This exertion can cause an overload of the system, the circuit breaker to trip and this can even blow your fuses. Check your air filters often, and change them every month to two months.

HVAC Unit

Dirty Coils

Condenser coils are located in the outside unit of your air conditioning system and serve as a conduit for the refrigerant used for cooling. The coolant absorbs heat inside of your home, travels to the condenser coils that allow the air coming from the fans to cool down the refrigerant before it returns to the inside of your home. If the condenser coils are clogged up by dirt and debris, they will not effectively cool down the refrigerant, causing your system to try harder to cool your home, leading to overheating. Turn your system off, use a weak stream of water and wash the coils. If you don’t feel comfortable tinkering around your unit, get it done by a professional.

Refrigerant Leak

The refrigerant fluid circulating through your HVAC system is a vital component of the entire system. If there is a leak somewhere and there is not enough of refrigerant fluid in the unit, the system will heat up, trying hard to cool the rest of the refrigerant down. That, in turn, will draw more energy and could trip the circuit. Be careful while searching for the leak and call your contractor to perform the necessary repairs and fill up your system on refrigerant.

Fan Malfunction

If your fans are not working, nothing will pull cool air through the coils, the compressor and the refrigerant will not be able to cool down. This error will force your air conditioner to work harder and trip the circuit once again. Call a professional to fix your fans and avoid blowing your fuses in the future.
