Many people practice preventative maintenance on their units by incorporating a couple of simple tasks. These include changing filters, making sure no items are blocking vents, clearing away debris from outside units and hiring technicians to come out once a year to look over HVAC units in the house or office.

A question that is often asked is, “Can cleaning ducts in your home or office have a positive effect on the air you breathe?” It most instances, the answer is yes! People who have had their ducts cleaned professionally report a great improvement in their air quality. In fact, not only was there a reduction in allergies experienced by people, but they reported their HVAC system functioned at a higher level with better airflow and as a resulttheir house or business smelt better. Some HVAC professionals have the opinion that cleaning air ducts can help stop mold from growing and suggest you have it done simply for peace of mind. This is because, depending on the type of mold that is present, it can be quite detrimental for your health.

How often should you have it done? Air duct professionals say at least every 3 years, but if you experience continual asthma or breathing problems you may want to consider having it done once a year. Some other issues to take into consideration would be, do you have pets? Do people smoke inside the house? Have you had any construction or home improvements carried out that caused dust? How clean is your home in general? How old is your home?

There is more to getting the job done then just a simple duct vacuuming. During a cleaning, coils and the central system will be cleaned. This can help you save on your energy bill. Coils and blowers that are dirty can be causing your HVAC system to lag in its efficiency by 40%.

Depending on who you talk to, or what you read some consumers believe hiring a professional to clean ducts is unnecessary and a waste of money. Or, there is the worry that an unexperienced duct cleaner may break your HVAC system or do nothing more than kick up dust and dirt. If you choose to hire someone, be sure to check their credentials and references. A license is not needed to be a duct cleaner.

Reducing Allergens at Home

Allergens in the home can bring on asthma or hay fever and even be the catalyst for various allergic reactions. Allergens are transported into your home via the air. They then land and settle all through your house, landing on surfaces such as counter tops and furniture. The airborne particles can be anything from pet fur and dander, mites, mold and insect droppings. Your HVAC system can help with this issue.
Here are some useful tips to reduce allergens in the house.

Look for signs of mold. If you have areas in your house that are humid and damp, mold could be thriving. Be sure to pay attention to your condensate drip pans, evaporator coils, the air handler and ducts throughout the house. Mold can be very dangerous to your health depending on its strain, so it is important to stay ahead of it.
Be sure to invest in furnace filters that are high quality. View them as your first attack on bad air quality in your house. A Merv 8 rating on a filter is what you should be looking for as they will do a good job of containing particles that are microscopic. It is important to check your filters once a month, but a good rule of thumb is to replace them around the 3 month mark. A dirty filter can’t do its job properly and will not be able to trap allergens. 
Preventative maintenance on your HVAC system is a great way to tackle allergens. Book an appointment at the start of spring to make sure your system is running to its full potential. This will keep it operating well and hopefully find small issues before they turn into big problems. Your technician will look to make sure there are no blockages and confirm your system is clean and helping you in the fight against allergens.
Dust, dust and dust some more! Dust over your vents and registers. By making sure the vents are clean dust won’t be circulated through the house. A damp cleaning cloth is a great tool to use so it traps dusts, and doesn’t just stir it up to go and land on another surface.
Check your units, both the outdoor and indoor units. Confirm they are free of blockage and debris. The air your unit pulls from the outside will circulate through your house. Removing dust and dirt from around the outside unit will help ensure your air quality inside your home is high.
