Signs You Need Ductwork Repair: Can Your Air Conditioner Be Damaged by Poor Insulation?

If you’re not sure whether or not your ductwork needs to be repaired, there are a few signs that will tell you. One of the most common is that while your air conditioner is running it feels less cold than usual. This can happen because insulation around the pipes isn’t doing its job, and heat from outside can sneak in and make things hotter inside before it’s blown out by the fan.

Another sign of poorly insulated ductwork would be rust on the pipes. If these sound like issues that may have been happening for some time now, then you should contact a professional ductwork repair technician to look at your HVAC system as soon as possible!

What Is Ductwork Repair?

Ductwork repair is the process of fixing cracks, leaks, and other issues that may be causing your HVAC system to not work properly. There are a variety of signs that you might need ductwork repair in order for your air conditioner to function at its full potential.

Only well-trained HVAC technicians can really get this job done perfectly, though. So you need to be careful about who you hire for this job.

Ductwork repair should be done both to ensure your HVAC system is working properly and also because poor insulation in the duct sealing can cause substantial damage to the heating, ventilation, or air conditioning components of your home’s cooling system as well!

When it comes time for ductwork repair services, contact only the most professional and certified HVAC company.

Signs That You Need Ductwork Repair

There are some signs that you can spot to determine if you need ductwork repair. If your air conditioner is working, but it’s not as effective at cooling your home, then this could be because the insulation in your ducts has deteriorated and needs to be replaced or repaired. The damage from a poor-quality installation can over time manifest itself through reduced airflow capacity of the HVAC system.

Some signs of air duct repairs are:

You’re Noticing a Drop in Temperature

When the furnace or air conditioner is on and the temperature is still not set according to the thermostat, it means you’re heating and cooling system needs ductwork repair.

Warm spots or dead spots in your house are also a sign of the wear and tear caused in the ducts.

Your Furnace Is Blowing Cold Air

If your furnace is blowing cold air, this could be a sign of ductwork repair. The problem may not just be with the thermostat and it’s time to get out those tools again. It is recommended to get ductwork repair if you suspect something is wrong with your air conditioning and heating system.

In the summer, it can overheat due to inefficient cooling; in the winter, the problem is that does not heat properly because of insufficient venting. In both cases, poor insulation leads to condensation buildup between wires or inside coils.

There’s an Unpleasant Smell Coming From Your Vents

If you smell a strange and unpleasant odor coming from your vents, this might be a sign of ductwork repair. Poor insulation can cause the buildup of condensation which leads to mold or mildew growth in and around the coils.

Insulation also inhibits airflow and causes more strain on your system, leading to higher energy costs.

The Blower on Your Furnace Isn’t Working Properly

If your blower is not working properly, this could be a sign that you need ductwork repair. A clogged filter or duct leakage will make the airflow less efficient and increase energy costs.

Air Ducts Not Working Properly

Air ducts are used to deliver the cool or warm or conditioned air from the air conditioner or furnace to the far corners of your home. If they have leaks and are not insulated, this will lead to wasted energy and a higher utility bill.

If you turn the temperature on your thermostat to a level that is not comfortable, it could be time for ductwork repair. This indicates problems with insulation or airflow and if left unchecked will lead to mold contamination in the home.

You Notice Mold or Water Damage on the Ducts

If you had no idea that these systems even needed repair.  Insulation needs to be replaced every five years and ducts need to be cleaned annually or when you notice mold on the inside of your air vents.

You don’t think about them until they stop working properly, but it’s important for homes in humid climates like Florida. Mold and mildew can grow on ducts without proper air circulation, which will cause the HVAC system to work harder and eventually break down.

It’s also important for homes in dry climates where there isn’t enough humidity but a humidifier can help regulate temperature.  Insulation needs to be replaced every five years and ducts need to be cleaned annually or when the season is about to change.

HVAC System Is Not Working Properly

Is your HVAC system working harder than usual? Does it feel hot inside at night even though the temperature is set to a lower setting or fan on low?  If yes, then you might need ductwork repair.  When airflow isn’t properly regulated in the ducts, this often leads to poor insulation and air quality.

How to find Air Duct Repair Companies

It can be difficult to find the right ductwork repair company to help you.  If your HVAC system is unusual, it might be difficult for them to come up with a solution without examining the inside of your house or installing equipment on-site in order to diagnose what’s wrong.

There are ways that you can find these companies through online listings, review websites, and even by searching your local area.
