An anemometer, a test instrument that measures air velocity is used to determine the average air speed 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. Traverse the airflow in the exhaust duct.

1. Seal Windows and Doors. The weatherstripping on windows and doors deteriorates over time, letting cold or hot air in.
2. Add Window Drapes, Shutters Or Blinds. Sunny rooms tend to feel warmer than rooms that are dark.
3. Add A Programmable Thermostat Strategically.
4. Install An HVAC Zoning System.
5. Add a Ceiling Fan.

15 Tips on Balancing the Temperatures in Your Home

1. Close or Open Your Register.
2. Try a 2 Degree Offset.
3. Check Filters for Cleanliness.
4. Install Window Coverings to Prevent Heat.
5. Avoid Placing Electronic Equipment Near Thermostat.
6. Check for Drafts.
7. Adjust Ceiling Fans.
8. Prevent Airflow Restrictions.

Air balancing aims to correct these types of airflow issues and evenly distribute temperatures throughout. The process requires testing and modifying an existing HVAC system in order to deliver the optimal flow of air conditioning to every space in the building.

Air balancing your system requires the skills of an HVAC technician, and you can expect it to cost $1,000 – $3,000. This cost varies depending on the number of ducts you have, running $75 – $150 per duct. Additional costs include replacement parts, and the installation of new ductwork can be $150 – $250 per duct.

6 Tips to Correct Unbalanced Indoor Heating and Cooling Issues

1. Check Thermostat Settings. Sometimes the thermostat is the culprit for uneven temperatures in homes.
2. Invest in a Zoning System.
3. Check Air Vents.
4. Inspect Air Ducts.
5. Replace or Add Insulation.
6. Check Air Filters.

8. 4 Common HVAC Mistakes You Should Avoid.

Start the system by switching the thermostat to heating or cooling. Then adjust the temperature setting to bring the system into full operation. Drill static pressure and temperature test ports before and after the air moving equipment and a test port five feet after the cooling coil for temperature measurement.

If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you’re cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees.

The fan is what blows air in and out of your home’s vents. A fan clogged by dirt, a stuck wheel, broken motor, or a loose fan belt are all common problems that reduce the amount of airflow you feel coming from your vents.

Steps on Cleaning your Air Ducts and Vents

1. Cover Supply Registers.
2. Turn on Fan.
3. Clean Supply Registers.
4. Clean Return Air Registers.
5. Turn off power connected to the System.
6. Unscrew Air Duct Covers.
7. Vacuum Clean the Air Ducts.
8. Clean Blower Compartment.

A specific duct may be clogged if there’s no improvement. From there, you can inspect your ductwork by first unscrewing the vent covers and checking behind the vent grille for debris. Use a flashlight to check the inside of the ducts, taking note of any damage around the seams and making sure the dampers are open.

When it comes to the nitty gritty, cleaning air ducts is not a do-it-yourself job. It requires tools, such as a high-powered vacuum and rotary brushes, that you don’t have lying around in the garage. In addition, an improper cleaning job could damage the ducts, resulting in expensive repairs.
