Should You Be Worried If the Heater Smells Funny When You Turn It On?

December 14, 2020 by advancedairsolutions1 Leave a Comment

Old heater HVAC unit in an old home With the cold, damp North Carolina winter weather around the corner, more families will begin using their home’s heating system again. If a strange smell fills the house when the heater is turned on, this may be a sign that it is time for furnace maintenance. While it could be a simple fix, the issues should be addressed as soon as possible to avoid more expensive repairs in the future.

Dusty Smells

Just like any other spot in the house, a furnace can accumulate dust throughout the year. Heaters produce these burning smells when burning off dust or debris. Luckily, this common smell should clear up shortly on its own. If the smell persists, then it may be time to replace the filter or schedule a professional deep cleaning.

Electrical, Burnt Smells

An electrical burning smell may be more concerning. Wires, metal, or electrical units that are too close to the heater can cause an electric or metallic smell to fill the house. As a safety measure, an overheating system will normally shut off, but this won’t apply if the electrical components have been damaged. Shut off the heater immediately and request HVAC maintenance service.

Rotten Egg Smells

A natural gas leak will produce a sulfur-like smell in the air vents. Although natural gas is odorless, mercaptan, a chemical that smells like rotten eggs, is added so that residents are quickly alarmed that there is an issue. Natural gas is highly flammable and long-term exposure can be poisonous if left undetected. All residents should evacuate the house quickly, pets included, and contact their gas company to identify and repair the issue.

Although some odors from the heater are short-term and harmless, the smell of electrical burning or rotten egg should be addressed immediately.

How Moisture Affects Your Home’s Foundation

February 3, 2020 by advancedairsolutions1 Leave a Comment

Example of moisture affecting a home's foundation Often, homeowners don’t think about maintenance for their home’s foundation until an issue arises. Especially here in coastal North Carolina, moisture is an ever-present risk to the safety and longevity of a property’s foundation. When moisture levels are high, it can cause the soil around the foundation to expand and push on the foundation. Then, as the soil dries, it contracts and moves away, causing a dangerous cycle that can hinder the integrity of the foundation. Understanding the causes and common signs of an issue will help homeowners catch a problem early and prevent expensive—and dangerous—damage.

What Causes a Moisture Problem?

Living by the ocean comes with many perks. But it also means a constant battle to manage moisture levels. While most homes here in Wilmington are built without a basement due to the high water table, water can still impact the foundation and crawlspace area under the home. The most common cause of moisture damage comes from heavy rainfall and improper drainage. Particularly if drainage leaves water settling unevenly on the property, it can cause the foundation to shift and crack. Trees can also become a culprit for moisture damage if they are planted too close to the home. The roots can expand, collecting moisture underneath the foundation and drying out the surrounding areas.

What Are the Signs of a Moisture Problem?

The first sign of a moisture problem is often visible water. If water is leaking or pooling around the exterior of the home, this is not a good sign. Homeowners should also regularly check the crawlspace for signs of wood rot or mold. Black or brown mold could be a sign of rot fungus, which can cause serious structural damage to the home. Other signs of damage include cracks and gaps in the floors, walls, concrete, and chimney structure. If doors and windows become skewed, making it difficult to open and close, this could also be an indication of the foundation shifting due to moisture.

Moisture can wreak havoc on your home’s foundation and crawl space. But with regular inspections and maintenance, you can help protect your biggest investment from serious damage. Let our expert team at Advanced Air Solutions help you with structural repairs and crawlspace renovations to seal out moisture and remove contaminants.

Air Duct Maintenance: Three Signs That It’s Time for a Cleaning

November 18, 2019 by advancedairsolutions1 Leave a Comment

Determining how often to schedule a professional air duct cleaning can be tricky. While the National Air Duct Cleaners Association recommends a cleaning every three to five years, more frequent cleanings may be advised, particularly if a family member suffers from asthma or allergies. The Environmental Protection Agency (EPA) also recommends that an air duct cleaning be performed if homeowners notice one or more of the following signs.

Mold Is Visible on Ducts or Other HVAC Components

A serious health hazard, the Centers for Disease Control (CDC) notes that exposure to mold can cause a wide range of respiratory concerns in people of all ages, particularly children, the elderly, and the immune-compromised. If it is suspected that mold is present in the air ducts or obvious mold growth is visible, it’s important to contact an air duct cleaning service right away to mitigate the issue.

Bugs, Rodents, or Other Vermin Are Infesting Ducts

Particularly during cold winter months, warm air ducts make cozy environments for rodents and insects to thrive. Not only can they contribute to hygiene and air quality concerns, but they can also destroy the ductwork itself. If any vermin are seen entering or exiting vents, an air duct cleaning can resolve the problem and help prevent further damage.

Excessive Dust and Debris Are Noticeable

Over time, dust, dirt, pet hair, and other debris build up in air ducts, causing restricted airflow, potential damage to ducts, compromised air quality, and even increased electric bills. The issue may become evident when dust is visibly released into the air from vents or a buildup is noticeable on registers. A qualified air duct cleaning professional can help remove the majority of these particles.

If you’ve noticed signs that your air duct system may need to be cleaned or it’s been more than three years since your last cleaning, the skilled contractors at Advanced Air Solutions can help.

Should Crawl Spaces Be Ventilated?

September 24, 2019 by advancedairsolutions1 Leave a Comment

Many residences have crawl spaces to give homeowners access to their utility systems. Unfortunately, crawl spaces tend to trap moisture, which can lead to the growth of mold, mildew, and rot.

Issues With Enclosed Crawl Spaces

Example of how the crawl space of a home should be ventilated

Enclosed crawl spaces are typically built with solid concrete or masonry foundation walls. These extend to the structure’s footings, where crawl spaces come into contact with porous materials, like wood or insulation, that trap water when they get wet. The resulting humidity often promotes the growth of fungi and mildew, which can cause people to get sick.

The Assumed Benefits of Ventilating a Crawl Space

Crawl space ventilation allows air to circulate under the floor, potentially preventing the buildup of moisture. However, ventilating a crawl space can increase a home’s energy bills while not keeping it as dry as many believe.

To Vent or Not to Vent

Research conducted by Advanced Energy, a global energy company, yielded surprising results about the effects of ventilating a crawl space. They monitored a modular housing development in Baton Rouge, LA, which is hot and humid for most of the year. They also monitored 12 stick-framed homes in the colder, drier climate of Flagstaff, AZ. Their research found that unvented crawl spaces stayed drier than vented ones, no matter how hot or humid it was.

Crawl Space Encapsulation

Because a significant amount of air exchange takes place in crawl spaces, having mold or mildew in this part of the home can seriously affect indoor air quality. Encapsulating a crawl space in a polyethylene vapor barrier can drastically reduce moisture infiltration without relying on expensive ventilation options. Encapsulation can also lower energy bills and help heating and cooling equipment last longer between HVAC maintenance checkups.

Encapsulating a crawl space is an effective way to prevent moisture from being trapped in crawl spaces. For decades, Advanced Air Solutions has helped people in Wilmington, NC and the surrounding areas maintain a high level of air quality in their homes.

How to Decide Whether an A/C Unit Should Be Left on During a Vacation

July 6, 2018 by advancedairsolutions1 Leave a Comment

Most Americans spend practically the entire year looking forward to a relaxing vacation. Stressing out about the state of an air conditioning unit should be the least of a vacationer’s concern! Before taking a trip, here are factors that should be considered when deciding where to set the thermostat.

Length of Vacation

Leaving home for a day is different from leaving for a week, even when it comes to air conditioning. For a short trip, leaving a properly maintained air conditioning unit on during an absence is often the preferred choice. This is because, after the home warms, it takes a great deal of energy to lower the temperature back to a comfortable state. Therefore it can be more economical to just leave the air conditioner on during a short absence. For longer trips, it makes more sense to expend energy to re-cool a house than to keep it cool while it sits empty for multiple days or even weeks.

Special Considerations

If the weather is predicted to be cool and rainy, leaving the A/C off is a safe bet. Hot, drier forecasts indicate the unit should be left on to prevent cooling systems from working overtime. This will also prevent any pets left at home from becoming uncomfortable or distressed. Finally, it’s helpful to know the structure of the home to understand how to plan a vacation. Homes with a great deal of attic insulation, lower air filtration, and efficient windows are less likely to become drastically overheated if the air conditioning unit is left off. Any necessary structural repairs, such as crawl space repairs to seal out moisture, should be completed before a trip.

Air Circulation

One last consideration to make is whether or not to leave the air circulating in the home regardless of temperature conditioning. For those with homes in humid environments, air cycling can help reduce humidity and protect hardwood floors, doors, and cabinetry. Keeping humidity down can also reduce heat in the home, making it easier to cool upon return. In addition to this, it can minimize build-up that requires air duct cleaning.

More Energy-Saving Tips

Whether the air conditioning unit is on or off, there are other ways to conserve energy for a vacation. Closing curtains can significantly reduce the amount of heat that is trapped in a home, regardless of whether the air conditioning unit is on. Make sure to turn off the main water supply in advance of an extended absence; unplugging electronics and turning off unnecessary lights can also cut down on waste. For those looking for a tech-savvy way to reduce energy use, Advanced Air Solutions recommends a wifi thermostat. It works through an app on your smartphone and lets the customer check the temperature and humidity in the home while away.

While all of these tips are helpful, staying cool requires a reliable air conditioning system above all else! If you need an examination or an upgrade, get a free estimate from Advanced Air Solutions or give us a call at 910-791-7888 today!
