In general, you need to take a static pressure measurement on the return and supply side of the air handler. This kit is designed to easily and quickly perform this test. Compare this measurement to the manufacturer's max static pressure value. If the TESP is too high, it indicates there's an airflow issue.
#1 Moisture and Condensation
Increased moisture within the home is a sign that your furnace venting isn't adequate. Without proper ventilation, fumes from the furnace leak into your home and cause condensation. This moisture is most notable in the morning and when you first turn on your heating unit.
Perhaps you're hearing odd whistling even when not windy outside? Airflow issues can cause imbalanced pressure in your home which produces these symptoms. Weak Air— If you're noticing the velocity of the air coming through your HVAC system's vents is weak, this is another common sign.

How much does it cost to have your HVAC system balanced? Getting an air balance in HVAC systems, with no significant issues or modifications, can range from about $200 to $500. This typically includes airflow measurements, adjusting dampers, and ensuring proper temperature distribution.
A small brush is usually enough to clear debris off the screen. For more stubborn buildup, you can use a shop vac, but that usually isn't necessary. To start, use a wire brush to remove: Leaves: Leaves that fall from deciduous trees or are blown by the wind can be sucked toward the intake vent and block it.
Turn your HVAC system on and return to the areas where ductwork is accessible. Check the connections between each section of duct, placing your hand over the metal. If you feel air against your hand, the connection is loose and there is an air leak.
If the intake pipe becomes blocked, the heating system will likely stall and turn off as it can't pull in the required air for the combustion process. If the exhaust pipe becomes blocked, a safety mechanism should trip to prevent dangerous fumes from entering your home.
A dirty or clogged air filter is one of the most common culprits for a furnace running without blowing air. Importance of Clean Filters: Air filters trap dust, debris, and allergens, ensuring clean air circulates through your home.
First, shut off the power to the furnace at the circuit-breaker box. Look for your furnace intake pipes, which are often white or black PVC pipes that exit a wall close to your furnace. Find where the intake pipes exit on the outside of your house. They are close to where your furnace is on the inside.
Your exterior furnace exhaust pipe is typically located on your home's sidewall, although it can be found on your home's roof in some cases.
If you notice a change in the airflow of your HVAC system, then you should look into calling a professional. They can come out and test your equipment to determine how strong the airflow is. How strong should air come out of vents? The recommended airflow for each room is typically 50 cubic feet per minute.
An anemometer, a test instrument that measures air velocity is used to determine the average airspeed in the duct. Then the average feet per minute is multiplied by the area of the duct in square feet to determine the airflow moving through the duct.
Your ductwork carries your household's air, so you want to ensure they're in excellent shape by routinely inspecting them. An air duct inspection costs $230 on average, though it can range between $140 and $380 depending on the type of test a pro runs and the amount of ductwork you have.
Use a brush to loosen any buildup of dust in the ductwork. Lift register and insert vacuum hose as far into the piping as it can go. Turn the vacuum on to capture as much dust as possible that the fan is pushing through the ductwork.
Put the glass with the handpiece into the water-filled ultrasonic bath. If possible, set the temperature to 50°C (122°F) and activate the ultrasonic power at your usual setting for approximately 15 minutes. Rinse the AIRFLOW® MAX handpiece with tap water.
Incorrect Slope: High-efficiency furnaces produce condensation that needs to be drained; otherwise, it will block the vent and trigger a furnace shut down. If the horizontal slope doesn't meet the minimum ¼” pitch requirements, the condensation will not drain properly and cause venting problems with your furnace.
Add or remove supply and return ducts to deliver enough air to each room. Seal or insulate accessible under-insulated ducts. Add dampers to the ducts. This directs the airflow coming from the HVAC unit and shifts the desired amount to each room.
Duct Replacement Cost by Home Size
Larger homes require more materials and labor to replace the entire duct system. On average, the cost ranges from $2,000 to $5,000 for a small to medium-sized home. However, duct replacement can run as low as $1,400 for smaller homes and as high as $9,000 for larger homes.
