Can Ductwork be Repaired?

Technicians Repair Ducts.

Can ductwork be repaired?

If you’ve noticed one area of your house heats or cools less than others, you might have a problem with airflow and ductwork. Your ductwork could be leaking or otherwise damaged. Duct repair is actually one of the least expensive of fixes you’ll need when it comes to your HVAC system. It’s also the least disruptive of repairs. More often than not, the repairs simply involve having the ducts sealed, which will improve the airflow, as well as improve indoor air quality and help prevent safety hazards like “backdrafting,” in which combustion gases get released in the house instead of escaping outside.

To further improve your indoor air quality, you might also consider having your ducts professionally cleaned. A cleaning will eliminate significant amounts of dust, allergens, and other contaminants that affect your safety and health. For expert duct cleaning in Cumming, GA, look to the professionals at Kennon Heating & Air Conditioning. Schedule a service online or by calling 678-778-1328.

How do I check ductwork?

If your ductwork seems to be causing problems with airflow, you can check your ducts yourself. Most of your ductwork can be accessed either in your attic, crawlspace, or basement. Gaps, tears, and disconnections should be obvious. You should also check for any duct tape, which will indicate someone has made a duct repair before to patch a leak.

Also, place your hand over connections to feel for leaks. Anytime you feel air blowing on your hand, you have a leak. Use a grease pencil to mark the leak so you know where to seal it. If you don’t detect any leaks, poor airflow might be caused by an obstruction inside the duct that can be removed with a professional cleaning.

How do you fix a leaking air duct?

In some cases, duct repair is a fairly simple process. Once you’ve found the leak and marked it, you can often seal the leak using professional-grade aluminum foil tape or a mastic sealant. Don’t use standard duct tape to seal leaks.

For duct leak repair:

  • Clean the area around the leak first so the sealant will adhere.
  • For flat surfaces, seal the leak by placing a strip of foil tape over the damaged surface.
  • Apply mastic sealant to gaps that you can tape. Spread the sealant with a paintbrush.
  • For gaps that are larger than 1/4-inch, you’ll have to use a combination of mastic sealant and foil tape.

Can you use Flex Seal on ductwork?

Flex Seal is a brand of rubber sealant used in a variety of applications across a wide spectrum of industries. It’s used on concrete, metal, and wood, as well as for duct repair.

For do-it-yourself duct repair, you want to keep several materials at hand for quick fixes. First, for small holes, you want to keep a variety of sealants on hand including mastic sealant and aluminum foil tape. You must use foil-backed tape because it holds up to high heat. Other types of tape, like standard duct tape, can be a smoke and fire hazard. For larger holes, you’ll also want to have 26-gauge sheet metal patches handy. To work with the sheet metal, you’ll need a power screwdriver and sheet metal screws. Other useful tools and materials will include a grease pencil to mark the leaks before sealing them and a flashlight or other light source to see in your attic or crawlspace.

Should ductwork be replaced after 20 years?

Like other components of your HVAC system, after about 15 to 20 years, you might want to consider having your ductwork replaced. While it might seem your air ducts do very little but push air through your system, they’re actually continually expanding and contracting as temperatures change. That’s often why leaks develop as the expansion and contraction open gaps in connections. While these gaps can be sealed with some simple duct repairs, over time the ducts will begin to operate less efficiently. This can cause more strain on your HVAC system and lead to it operating less efficiently as well. That can also cause it to break down more often. New ducts can end up saving you money in the long run on repair costs and energy bills.

Age is usually the deciding factor between duct repair and replacement. As with anything else, your air ducts will last much longer if you have them inspected and maintained regularly along with the rest of your HVAC system. Having an HVAC professional like those at Kennon Heating & Air Conditioning inspect your ducts is the best way to determine whether or not your ductwork needs to be replaced.

Does Furnace Need Maintenance?

Why HVAC maintenance is important

Are you finding your utility bills getting higher for no reason, especially at peak seasons when your HVAC system is running most? One of the best reasons to get regular HVAC maintenance is to save money. When your air conditioner and heater is running efficiently, it costs less to run it. If your system is well-maintained, it will run efficiently, and you’ll save money.

Regular preventative maintenance will also save you money on repair costs. Let’s say you’ve scheduled furnace maintenance in the fall before winter’s chill really sets in, and the HVAC technician discovers a fan motor isn’t working quite right. Every part of your heating system relies on the others to work right. A broken, failing fan motor could lead to your furnace overheating, and, if left alone, that could lead to expensive repairs or even premature system replacement. If the technician catches the problem soon enough, the fan motor can be repaired or replaced and you’re not out thousands of dollars on a new system. If you want to save money with air conditioning & heating maintenance in Cumming, GA, set up a maintenance plan with Kennon Heating & Air Conditioning by calling 678-778-1328.

What is included in furnace maintenance?

When you set up a furnace maintenance service, you’re getting a thorough tune-up and inspection of your system. This means every component is checked, adjusted, cleaned or lubricated, and tested. Specifically, your HVAC technician will:

  • Inspect vents and air intake grilles and remove anything blocking them.
  • Look at the heat exchanger and make sure it’s not damaged or corroded.
  • Check and test blower motor for amp draw and check the electrical connections, replacing and repairing damaged wiring.
  • Inspect burners and sensors and examine belts for damage.
  • Inspect and calibrate the thermostat.
  • Clean or replace the air filter.
  • Test safety controls and the start-up cycle.

How often should you have your furnace serviced?

You should schedule regular furnace maintenance at least once per year. It’s preferable to schedule this maintenance service in the fall before usage hits its peak in the winter.

Are furnace maintenance plans worth it?

Signing up for a furnace maintenance plan can be valuable in some instances. While you might get lucky and never need a repair, a maintenance plan can offer you a little peace of mind knowing your system is working efficiently. You’ll also be alerted to any potential problems that can be prevented before they create real havoc for your system, such as overheating. Regular maintenance will also benefit older HVAC systems, especially if they are older than 10 years. Moreover, some manufacturer’s warranties are voided if you do not sign up for a plan. Plans are also generally inexpensive, and often can be paid in installments.

Furnace maintenance tips for winter

While having a regular maintenance plan in place can save you money over the long term, as you prepare for winter, you can follow these tips to ensure your heater is going to keep you warm throughout the season:

  • Change the filter regularly, about four times during the year.
  • Set up a regular professional maintenance plan, especially if the unit is 10 years old or older.
  • Check your warranty so you know what’s covered and for how long if repairs are needed.
  • If need repairs, don’t try to fix it yourself. Rely on experts like those at Kennon Heating & Air Conditioning.
  • Clean your air ducts, especially after any home renovations or other repairs.

Is furnace cleaning worth it?

You want to keep your furnace running as smoothly as possible through the coldest part of the year. With yearly furnace maintenance, service components are cleaned and lubricated as needed. And while this will keep your system serviceable, it might not get rid of all the dirt, dust, and grime that accumulates over the years. From time-to-time, you might want to have your whole HVAC system cleaned. A thorough cleaning includes the furnace and air conditioner as well as your air ducts. This will clear the dust and debris in the air that your furnace circulates when it is heating your home.

How do you know when your furnace needs to be replaced?

No matter how often you perform furnace maintenance, your furnace will eventually come to a point where it needs to be replaced. Some common signs that will alert you that it’s time to replace your furnace include:

  • Unusual odors, like a strong smell of fuel or burnt odor that doesn’t go away
  • Turning the unit on and keeping it on is difficult
  • Discoloration of the pilot light, especially if the light is yellow and not blue
  • No heat or low heat is produced
  • Noises like persistent whistling, groaning, or banging
  • Reduction of air quality
  • Carbon monoxide detector inside the unit gets tripped

When is the Best Time to Get HVAC Repairs?

How often should HVAC be serviced? 

Here in the deep south, the summers are hot, humid, and muggy, especially here in Georgia. We’re close to the coast, so that ocean air just comes up on land and stays for three or four months. That is why professional HVAC repair is important to businesses and residents alike.  

Knowing how to HVAC repair is an important business here, and the professional HVAC repair contractor will advise customer if HVAC repair or replacement is the better choice. What is HVAC repair? HVAC is the acronym for heating, ventilation, and air conditioning and HVAC repair is the process of repairing the heating, ventilation, and air conditioning. 

Industry experts recommend you should have your HVAC serviced by a professional once every six months. In the meantime, though, there are things a homeowner should do as maintenance steps: 

  • The HVAC Filter: This is the least expensive thing you can do for your part of the maintenance but can save you hundreds, even thousands of dollars in HVAC repair costs. The air filter should be changed or cleaned every thirty days. If you have indoor pets, love in an area with a lot of construction or traffic you may need to change or clean it every two weeks. Same every two weeks if any occupants in the house have allergies or respiratory issues, or if you have several pets indoors. 
  • The Outdoor Condenser Unit: The outdoor component to your HVAC system is built for the outdoor elements, but it does not need to have debris and dirt collected and sucked upon it. As a homeowner, part of your HVAC maintenance is keeping the area immediately around the outdoor unit clean and clear. Keep the grass trimmed away from the fan blades are clean will keep the need for HVAC repairs minimal. 
  • The Drain Lines: There is a drain line on ever air conditioner where the moisture that is pulled out goes. Every month when you change or clean the air filter, you should also check and clean the drain line too and clean it.  If the drain is allowed to get clogged, it can back up into the system and require HVAC repair, which can get expensive depending on how extensive the damage. 

Is HVAC tune up worth it? 

Yes! An HVAC tune-up is less than an HVAC repair, and much cheaper than an HVAC replacement. Think of your HVAC system like your car. You get a tune up for your car on a regular schedule, which includes changing the filter, oil and cleaning pieces of the machinery that makes your function.  The same is true with an HVAC. Consider the following benefits of an HVAC tune up: 

  • Normal wear and tear issues are addressed during an HVAC tune-up, keeping your unit from breaking down at an unexpected time, saving you’re the expense of an HVAC repair call.  
  • When your HVAC does breakdown, until your HVAC repair technician arrives, you’re without cooling.   
  • An HVAC tune-up will give your unit the best opportunity to perform at its highest capacity and keep the energy consumption minimal.
  • A longer lifespan for your HVAC system. Routine maintenance is essential to get the longest life possible at the optimal performance level. 

What is the life expectancy of a HVAC system? 

An HVAC system is a significant investment, so taking are of it is essential to getting most lifetime you can from the unit. In general, the majority of HVAC systems will work fifteen years, some can last twenty-five years. There are several factors that contribute to the longevity of an HVAC system and the amount of HVAC repairs your system will need. Things that can reduce your HVAC system’s life span include: :

  • Poor maintenance routine
  • Poor quality initial components
  • Oversized or undersized system
  • Improper installation 
  • Inordinately high usage 
  • Improper usage
  • Installation in corrosive or salty environment

With a regular HVAC system tune-up, small issues are found before they become a bigger problem that requires an expensive HVAC repair or replacement. 

Why is my AC running but not cooling?

There are several problems with an HVAC unit that will require a professional technician, but there are a few things a homeowner can do before having to make that expensive phone call. 

  • If the HVAC system will turn on and the thermostat is set correctly, the air condenser may be blocked or dirty. Look at the outside component and make sure there isn’t any debris, dirt, grass, trash, or weeds sucked up around it. 
  • Next, check the air filter and clean it or replace it if needed. A dirty air filter won’t let air into the evaporator coil, causing the coil to freeze up and the system won’t cool.
  • If those two steps don’t get your air conditioner cooling, you’re going to need an HVAC repair technician.
