Know These HVAC Airflow Problems

Know These HVAC Airflow ProblemsAirflow problems with your HVAC system can leave you dealing with discomforting issues like hot or cold spots, uneven temperatures in different rooms, and/or a drop in conditioned air output from the registers. What starts out as a gradual loss of comfort can escalate into a costly equipment breakdown or failure, so it’s vital to have the problem addressed. Here’s a look at some of the most common causes or airflow issues and what to do about them:

Obstructed Registers and Duct Openings

If you’ve closed some registers, or your return ducts are covered by furniture, drapes, throw rugs, toys or other items, it can cause temperature inconsistencies in different areas of your home and a damaging imbalance in system airflow. You can fix this by wiping down each vent cover and vacuuming out the duct openings, and then checking that your louvered registers are completely open and all supply and return vents are free from obstructions.

Clogged Air Filter

If you’ve neglected to change your system’s air filter and it’s become clogged by dust and debris, you’ll notice a drop in airflow at the registers. Restricted airflow can also increase your HVAC equipment’s workload and energy consumption, or even ruin a component. Checking the filter monthly and replacing it whenever it looks dirty is the best way to prevent such problems.

Ductwork Flaws

A ductwork system that’s poorly designed, damaged, or leaking can hinder proper airflow through your HVAC system. A trained HVAC technician should inspect your ductwork to determine the cause and the right remedy, which may involve repairing, sealing and insulating or replacing the ductwork.

Oversized Equipment

If your existing HVAC system wasn’t sized properly, it may be too large to effectively heat or cool your home. HVAC components with too much capacity will short cycle, resulting in a decline in airflow from the registers every time they cycle off. To solve this, a knowledgeable HVAC professional will need to complete a detailed load calculation and install correctly-sized new equipment.

How Insulation Affects HVAC Efficiency

How Insulation Affects HVAC EfficiencyHVAC efficiency depends upon more than just the make and model of your air conditioner or furnace. Insulation is one of the factors that can make or break both optimum energy efficiency and consistent comfort in your house.


Insulation For All Seasons


Heat energy is always in motion from a warmer zone into a cooler zone. Proper insulation effectively inhibits both heat gain in summer and heat loss in winter and supports maximum HVAC efficiency. The most cost-effective location for household insulation is usually the attic. Here’s why:

  • Solar heat radiating through the roof overheats the attic in summer, causing rooms below to become hotter, too. A bed of fiberglass or cellulose insulation in the attic floor effectively inhibits heat radiation through the ceiling and reduces the cooling load on your air conditioner.
  • In winter, heat from the furnace naturally rises in living spaces, radiating up through the ceiling into the colder attic. Proper insulation in the attic floor resists heat transfer through the ceiling and keeps heating costs lower.

How Insulation Pays Off

By reducing the effect of heat gain and heat loss, insulation boosts HVAC efficiency, maximizes performance of your air conditioner or furnace and helps control cooling/heating costs.

  • Shorter cooling cycles means the A/C compressor—often the largest single electricity consumer in a typical house—runs less and monthly electricity costs are reduced.
  • Gas-fired furnaces also use less fuel to keep the house warm as insulation reduces heat loss into the attic.
  • Manufacturer’s efficiency ratings are more accurate. Both the SEER efficiency rating for air conditioners and the AFUE rating for gas-fired furnaces are helpful factors in predicting the operating costs of a particular unit. The reliability of these efficiency calculations assumes that proper insulation is installed in the house.
  • Components of efficient HVAC units receive less wear and tear. System service life is extended due to shorter cycles and repairs are less frequent.

How Can Replacing HVAC Air Filters Impact Your System?

How Can Replacing HVAC Air Filters Impact Your System?HVAC air filters frequently fall victim to the “out of sight, out of mind” saying, sometimes going for months or even years without replacement. Changing your filter is one of the easiest HVAC maintenance tasks you can complete. It can also play a pivotal role in indoor air quality, HVAC efficiency and the overall lifespan of your HVAC unit.

What Do HVAC Air Filters Do?

The primary function of an HVAC air filter is to protect your system’s inner workings. A clean filter captures all the little particles that would otherwise pass through and foul up internal mechanisms, eventually leading to overheating, breakdowns, or ongoing diminished performance from gunk buildup. Additionally, air filters help remove dust, pollen and other common allergens from circulating inside your ductwork and household air.

Why Is Replacing HVAC Air Filters Critical?

Timely replacing HVAC air filters can significantly impact these primary areas:

  • Point temperature. When filters and ducts get clogged, less conditioned air can get to your living space, and it can take significantly longer for your rooms to come up to temperature.
  • Wear and tear on your system. A blower motor or A/C fan has to work harder if it’s drawing air through a dirty filter. If it gets really dirty, your filter may also release particles into the motor. Without these factors, your blower motor or fan will have a much higher overall life expectancy and much lower risk of costly repairs.
  • Your monthly energy bill. Your unit has to work harder and longer when the filter is dirty, so replacing or cleaning it regularly may instantly and significantly drop your energy bill.
  • Indoor air quality. Clean air filters can capture a significant percentage of airborne particles, so you’re not breathing them in anymore. This may help improve allergy symptoms and respiratory issues, such as asthma.

Don’t Overburden Your A/C – Lighten the Load on Your HVAC System

Don't Overburden Your A/C - Lighten the Load on Your HVAC SystemSummer temperatures are already here, and if you’re a homeowner or business owner in Georgia, your HVAC system probably gets a lot of use all season long. Unless you fully optimize its efficiency, you’re wasting money, and you might be overworking your air conditioner without even realizing it.

Whether you’re still in the construction process or have lived in your home for years, you have plenty of options for increasing your efficiency and lowering your bills. Don’t forget to schedule preventative maintenance for your HVAC system; you shouldn’t wait until a leak or problem for professional assistance, which includes everything from filter replacement to internal lubrication.

However, you can take matters into your own hands too. Make sure you have an energy-efficient summer by maintaining a regular duct cleaning regimen and inspecting your windows and door frames for any gaps or cracks. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a few more helpful ways to lighten the load on your HVAC system this year:

  • Increase insulation levels (choose insulation with R-levels worthy of Georgia summers)
  • Choose high-efficiency roofing and window materials
  • Add shade (e.g. exterior awnings or thick interior screens) to windows
  • Add exhaust fans to rooms that tend to be more hot or humid, such as your kitchen, bathroom and attic
  • Use appliances (e.g. your washer and dryer) before and after the highest temperatures of the day; this peak period is usually between 10 AM and 4 PM
  • Turn off appliances when you’re not using them

It’s also important to make sure your HVAC unit is in a shaded area. Direct sunlight can make your air conditioner’s job more difficult, consuming more energy than necessary, so it’s a good idea to plant a tree nearby or install an awning above it.
