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.


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.

Clean Your Outdoor Unit for Fall

After summer, we always get the urge to clean out our closets and our space to get ready for the new season. Preparing your home for fall should always include a scheduled maintenance of your heating, ventilation and cooling system to make sure you breathe clean and healthy air during winter and avoid break-downs and unnecessary expenses at a most unfortunate time. By cleaning both your indoor and your outdoor central unit you will prolong the life of your air conditioning system so take some time to make sure your outdoor unit is in good shape. Follow these simple steps for an easy DIY maintenance job.

Inspect the Filter

Usually located next to the air conditioner return duct, air filters with time get dirty and full of debris so locate yours and remove them. Wash your plastic and metal filters thoroughly with a garden hose to eliminate dust and dirt. Discard cardboard and fiber filters and replace the filters with new ones.HVAC System technician needs to be certified and trustworthy.

Turn Off Power and Open the Unit

Flip the breaker switch off on the unit and carefully remove the access panel from the vent openings.

Bring Out the Vacuum

By removing the panel, you will expose the condenser coils in your unit. Examine them thoroughly for debris and dust, and clean them with your home vacuum. Be careful not to bend the fins and coils. After vacuuming, get your garden hose again and rinse the coils well. When handling the condenser coils be careful and wear heavy gloves because the fins are sharp and often cause scratches and cuts you could easily have avoided with proper equipment.

Clean the Fans of Your Unit

Use a moist rag and carefully clean the dust from fan vents in the unit and the top panel. Screw back the panel and don’t forget to turn the power back on!

Efficient HVAC System

Getting an Efficient HVAC System

When considering an investment like installing a new heating, ventilation and cooling system, do your homework first and thoroughly research the market. Being realistic about your needs and shopping accordingly will save you a significant amount of money in the long run, so pay attention to these suggestions and choose a system that completely suits your home.

The Matter of Efficiency

Researching the effectiveness of the system you are considering can help you save money on your utility bills, since effective units cool and heat your space by using less power. When reviewing the specifications of your top options, look for SEER or AFUE ratings, as well as models that have energy stars.

The Matter of Size

Bigger is not always better, and HVAC systems are the perfect example. The size of your unit should be directly proportional to the square footage of your house because large units placed in small spaces and vice versa usually wear out faster. Small units need to work extremely hard to keep your desired temperature in a larger home, while large units achieve it too easily, which in turn causes them to continuously turn on and off, trying to keep the temperature constant.


The Matter of Quality

It always pays off to invest in quality. In HVAC terms that means your units will last longer and have fewer issues.

The Matter of Special Features

Newer systems come with a whole array of special features, many of which you might not even need. Research a bit what a particular feature stands for and opt for the system that ticks all your boxes.

The Matter of Installation

A good contractor can go a long way, so ask for recommendations and always make sure you use a licensed professional located in your area because that usually means they can react quickly if you have any questions or problems with your system.

Tips on Cleaning a Commercial Property HVAC System

Besides many other tasks that need to be performed day in and day out, being a responsible and efficient landlord or manager of commercial properties also includes taking good care of the HVAC system. By doing so you will eliminate odors, excessive moisture, and stop mold from developing in and around your units, as well as lower your energy costs and make your space a more pleasant place to live in. The easiest way to ensure that your HVAC system is working without a glitch is to follow these simple steps as frequently as possible.

Plan Your Action

Cleaning air ducts is not a risk-free activity and by doing so without being careful, you can release toxic contaminants into your building. In order to avoid possible injuries and discomfort, notify your occupants in advance and take all the necessary steps to keep them protected and your property in good shape.

Dispose of Standing Water

Cooling towers, (de)humidification equipment and drain pans are places where water tends to pool, which in turn can cause mold growth, increase humidity and release odors to your HVAC system. Dispose of all unnecessary standing water around your system, and frequently clean these surfaces.

How to find quality HVAC contractors

Time to Clean

Check both your outdoor and your indoor components and use different sized brushes to loosen dirt and debris that accumulated in the system. Use a vacuum cleaner to reach deeper into the unit and clean thoroughly.

Clean and Change Air Filters

If your building has reusable filters, check them for damage and clean them by carefully following the instructions from the manufacturer. Replace all used-up filters.

Apply Additional Protection

After cleaning all the surfaces, apply necessary sealants, antimicrobial agents and resurfacing materials following all the applicable instructions and regulations.

Do an Annual Inspection with a Professional

Checking the entire system once a year will help detect possible problems with the system and prevent significant malfunctions down the road.
