3 Reasons to Change your Filters

1- Air Quality

Air filtration is one of the least expensive ways to improve air quality. The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) suggests that filters should be cleaned or replaced not less than every 3 months.

2- Equipment efficiency

According to the US Department of Energy’s Federal Energy Management Program, air filters play a critical role in maintaining indoor air quality and protecting the downstream components of the cooling equipment (coils, blower, etc) from accumulating dirt that reduces equipment efficiency.

3- Contamination source

A dirty filter can become a contamination source if not cleaned or replaced. Dirty filters can also force air to go around and bypass filtration sections and the unfiltered bypass air deposits debris on the cooling/heating coils rather than on the filter.

Routinely change or replace filters based on either regular intervals or by visual inspection. Intervals can range from 1-6 months (some newer type and style filters indicate usage up to 6 months), depending on the dirt loading from both the indoor and outdoor air. Visual inspections of the leading edge side of the filters can help indicate frequency. In commercial facilities, measuring the pressure drop across the filter is the most reliable way to rate particulate loading on the filter.

6 Main Factors to Have Your Ducts Clean

Every home and business is different. Many factors influence the hygiene levels of your HVAC duct system including the type and frequency and proper maintenance of filter maintenance, A/C component maintenance frequency (evaporator coils, blower motors, pan treatments, etc), duct leakage, humidity levels and structure location, to name a few.

How often should they be cleaned?

The frequency of cleaning depends on many factors within the building. These 6 main factors are among a few to consider:

 
1- Renovations/Remodeling
2- Flood or water contamination
3- Allergies
4- Pets
5- Smoking
6- Moving into a new home

For best preventive measures, minimally, your A/C system should be inspected yearly and ductwork inspected every 2 years.

8 Reasons To Schedule A Preventative Maintenance

Once your A/C system has been properly cleaned and remediated, simple ongoing schedule maintenance inspections should be performed to ensure your continued clean and healthy air.

A clean and properly maintained system will help:

  1. Reduce musty odors associated with moldy systems
  2. Provide clean and healthy air flow
  3. Reduce the likelihood of equipment breakdowns
  4. Reduce AC electrical energy usage
  5. Increase or restore your A/C system capacity
  6. Reduced likelihood of condensate water flooding
  7. Extend your A/C equipment life
  8. Reduce the frequency of future duct cleaning

A dirty evaporator coil will reduce cooling capacity and degrade equipment, reducing energy efficiency. A clogged evaporator coil reduces air flow through the coil, causing the compressor motor to consume more energy.

Exposed to unfiltered outdoor air, condenser coils easily trap dust and debris, raising the condensing temperature and reducing the cooling capacity. According FEMP, a Pacific Gas and Electric (PG&E) study showed that a dirty condenser coil can increase compressor energy consumption by 30%.

Keep It Cool And Save Energy

Your heating and cooling system uses over 50 percent of your energy costs in your home.  While changing the air filter is one of the simplest things you can do to keep your air conditioner working, a regular maintenance routine with an air conditioning professional will keep your unit from malfunctioning during the hottest days of the summer.

A typical tune-up on your air conditioner it’s probably going to cost around $70 to $150. But also keep in mind, many companies do offer maintenance plans that might offer it at a little lower price by signing up for a whole year.

Many experts agree that it needs to be tuned up once a year every year. Also, if the outdoor coils are dirty, if the cooling capacity is not up to par and they are not getting air flow out things like that can show that the air conditioner needs to be tuned up. Going to the outdoor unit we check the indoor coil, the outdoor coil, the capacitors, compressor, do an all systems check on the electrical and make sure everything is tightened check the refrigerant level, the temperatures and make sure the system is efficient and operating as it should. It is true that you can lose up to 5 percent efficiency because if the system is not operating the way it’s supposed to such has dirty coil, over heated motors, lack of refrigerant effects how that system is efficient so as it goes through the year it can lose efficiency if it’s not tuned up properly.

 

Improve your Indoor Air Quality Today!

As the weather continues to cool down and allergy season hits its peak, homeowners may find themselves spending more time indoors. According to the National Air Duct Cleaners Association (NADCA), this gives an added importance to making sure that HVAC systems are properly cleaned and ready for the change in season.

NADCA, the HVAC Inspection Maintenance and Restoration Association suggests homeowners and building managers pay close attention to their air handling units and take the necessary steps to determine if a proper cleaning is in order.

“A dirty or contaminated air conveyance system will restrict air flow at the coil and blower, and also within the duct system,” said Bill Benito, ASCS, CVI, president of NADCA. “Your HVAC system should be inspected yearly and a complete system cleaning should be performed every 4-5 years.”

The frequency of cleaning may vary depending on certain factors; NADCA urges homeowners to consider the following:

  • Are there pets living in the home? Pet dander and hair can add to the amount of dust and dirt that accumulates in an HVAC system, restricting air flow.
  • Do any of the occupants of the home suffer from asthma or allergies? A proper cleaning of the air handling unit can improve indoor air quality and efficiency of the unit.
  • Is smoking permitted inside the home? If so, full-system cleanings may be required more frequently.

“When looking to hire a company or a contractor, it’s important to pick a reputable business whose technicians have gone through the NADCA certification process,” added Benito.

Learn how to extend life of your air handler unit.

As your a/c equipment ages, it can become less efficient, detrimental to your indoor air quality and parts will wear to the point that you may be thinking of replacement.  As a tune-up will restore most of your cars’ performance, precision tune ups and remediation to the air handler components can restore lost performance, efficiency and improve IAQ. It’s important to consider an AC Scheduled Preventative Maintenance Plan.

Evaporator / Cooling Coils:
ADAflorida.comThe efficiency of the cooling coils can be directly attributed to the level of cleanliness and can be directly measured by the pressure drop over the coils.  NADCA, The National Air Duct Cleaners Association, recommends  yearly inspections of the air handling unit and “cleaning is highly recommended for heat exchange coils, cooling coils, air flow control devices, filtration devices and air handling equipment determined to have restrictions, blockages, or contamination deposits that may cause system performance inefficiencies, air flow degradation or that may significantly affect the design intent of the HVAC system” (ACR 2006, NADCA)


Condensate Pan / Drain:
ADAflorida.comMicrobial-like growth, dirt and debris can clog condensate pans if not properly maintained, causing overflow within the air handler.  This condition could cause microbial growth to occur within the air handler and ductwork.  The pitch of the drainage pan is also important in assisting the proper flow to the building exterior.

Blower Wheels:
ADAFlorida.comBlower wheels and fins can become heavily soiled and less efficient if not regularly maintained and cleaned.  A dirty condition can also result in poor air flow.  Care must be taken not to unbalance the blades when cleaning but efficiency can be substantially increased.

Insulation Liner:
ADAFlorida.comThe liner on the internal surfaces of the air handler unit provides insulation and sound dampening.  However, in this microbially vulnerable area of the HVAC system, the liner can fail much quicker than the other components.   If degraded and flaking, particles can enter the air stream and cross-contaminate into the occupied spaces.  Closed cell insulation can be installed to extend the equipment life and provide a non-porous insulation liner within the air handler.

DID YOU KNOW THAT AIR DUCT CLEANING SAVES ABOUT 11% IN AIR CONDITIONING ENERGY USAGE?

ada-dirty-filter

It takes a lot of energy to heat and cool a home or building an in fact, the systems used for this purpose account for the majority of energy use. These systems – even in new buildings – tend to be dirty, and become heavily fouled through everyday use. Fouled heating and cooling systems can also be problematic for occupants, contributing to poor indoor air quality, system failure and increased energy usage.

Researchers have proven that properly cleaning even lightly-soiled heating and cooling systems through air duct cleaning services can result in energy savings of up to 11 percent. In addition to these savings, consumers who have their heating and cooling system cleaned can benefit from improved indoor air quality, air flow, reduced maintenance costs and extended life expectancy for the heating and cooling system.

While not confirmed, cleaning heavily fouled systems is expected to produce even greater energy savings.
