What causes condensation on air vents?

• <div><p>Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a <a href="https://www.angi.com/nearme/air-duct-cleaning/">local air duct cleaner</a> to clean and inspect them.</p></div>

Is it better to repair an AC or replace it?

• <div><p>Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around <b>15 years</b>, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">replacing the AC unit</a> rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.</p></div>

AIR DUCT CLEANING - debris in your air ducts can trigger asthma, allergies, unpleasant odors and create microbial growth. HVAC RESTORATION - if your home or business has been compromised due to fire, flood, smoke or water damage, your system should be cleaned as a part of your restoration plan. COMMERCIAL DRYER VENT CLEANING - clogged dryer vents restrict air flow causing increased utility cost and potential fire risks. We ensure your dryer vents are thoroughly cleanded, operational and up to code.

Heating and Air Conditioning questions, answered by experts

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
