As a homeowner, proactive maintenance is a vital part of keeping your home in tip-top shape! However, sometimes you may experience air duct issues or need air duct repair by a professional. If you notice your HVAC system is not running as efficiently as it used to, here are just some of the common air duct problems homeowners commonly face and how to prevent air duct problems in the future. 1. Dirty Air Ducts Not only do air ducts circulate warm or cool air through your home, but they also collect dust, germs, pet hair, and other contaminants. Over time, your air ducts will be lined with these contaminants, making it harder for air to flow and provide the heating or cooling you need. This is one of the most common air duct problems, but it is easy to prevent if you regularly have your air ducts cleaned. Clean air ducts improve indoor air quality, reduce odor due to contaminant build-up, and increase your HVAC efficiency, all of which are beneficial to you and your family! 2. Leaking Duct Work Just as your air ducts need to be cleaned, they also need to be checked for leaks. Air ducts can become loose or disconnected for a variety of reasons, including inadequate fastening or simply damage from age and use. When your air ducts leak, some of the air that is supposed to come from your vents escapes before it should. Ultimately, this causes your HVAC system to run inefficiently and increases your utility bill! The best way to prevent this problem is to work with a trusted HVAC specialist that will properly install, seal, and inspect your air ducts. 3. Improper Air Duct Design Ductwork in your home cannot always be seen, so you may not know how the layout or design of your air ducts is set up. If purchasing a home, make sure you are always getting a qualified individual to inspect all elements of the space, including your air ducts. If you are already a homeowner and notice your HVAC system is running poorly, start by checking your attic or basement for any obvious problems, as previous homeowners may have attempted DIY methods to fix issues. If you have concerns at any point, we encourage you to call us at AJM Mechanical for your air duct repair needs. Contact an Air Duct Specialist in Philadelphia Today! Whether it is a simple fix by needing your air ducts cleaned or your air duct system needs to be replaced due to its age, the more proactive you are, the better it is for your home (and wallet). At AJM Mechanical, we provide expert air duct repair in Philadelphia and surrounding areas like Northeast Philly, Bucks County, and Montgomery County. Call us today for expert ductwork inspection, sealing, and repair services. Improve your HVAC efficiency and indoor air quality now !

The summer months can be a delightful time, especially for those who enjoy soaking up the rays on a lazy Sunday afternoon. But, for those who find the heat to be a tad challenging, an AC unit is a blessing. Yet, if you’re concerned about the overall performance of your HVAC system, it may be time to call in a professional for some expert advice. There Could Be a Leak in Your AC Unit A major issue with AC units is that they have a tendency to leak if they are not properly cared for. This is usually caused by a clogged condensation drain line, but could also be tied to a damaged drain pan or a frozen evaporator coil. Regardless of the cause, it’s vital that customers get this problem fixed early on so that they can avoid the risk of an AC system failure. Clogged Air Filters Air filters help to trap small particles of debris like pollen and dust to stop them from entering the AC system. But over time, these filters can become dirty and run down, causing them to become clogged. These filters are easy enough to replace, so customers don’t have to worry about paying out for an entire AC replacement. However, in order to keep on top of things, customers are advised to schedule annual maintenance checks so that they can keep on top of their AC repair schedule and prolong its life. Key Internal Parts Could Be Damaged An AC unit may just seem like a huge box that puffs cold air, but in fact, it’s a very complex piece of machinery. If a key piece, such as a blower motor or a compressor, is not working as it should, then the entire machine could go into AC system failure. In some extreme cases, your AC could stop working out of the blue, making it in need of dire AC repair. Luckily, a lot of contractors offer a 24/7 Emergency Service line so that customers can receive help day or night. The Unit Could Be Outdated While the average AC unit tends to last 10 to 15 years, certain problems can decrease its overall lifespan. Plus, with new HVAC technology developing every day, an AC unit can become outdated very quickly. So, for customers who have had their unit for many years and are looking for a change, it may be time for an AC replacement. Again, many local contractors can help you to select the right unit for you and your budget. Schedule an AC Repair in Philadelphia Today! For a lot of people, AC units are a lifesaver, and when these machines start to fail, it can be extremely worrying. However, with the right help, customers can ensure that their unit remains in working condition for many years to come. Contact us to schedule an AC repair at AJM Mechanical today!

It’s too easy to rack up high energy bills when the temperatures continuously climb throughout the summer. However, poor energy efficiency can also lead to you needing an AC replacement sooner. There are several steps you can take to keep your AC energy efficient this summer. Clean The Filter Air conditioners suck in air, which then goes through a filter before it’s redistributed throughout your home. Dirt, debris, and allergens get trapped in the filter, so it can easily get clogged between maintenance appointments. Homeowners can easily clean their filters themselves. Check every couple of weeks to see if the unit is in constant use, and clean it or change it when necessary. Units with dirty filters have to work harder and use more energy. Prompt Repairs Broken air conditioners also use more energy than air conditioners in great shape. Contact a professional specializing in HVAC maintenance as soon as possible. This can also help save you money. When one component is broken or worn, and the more you keep using the unit, there is usually a domino effect as more parts break. Always stop using a unit and get it repaired as soon as possible. Weather Proofing Units must work hard to keep the area cool if it constantly gets hotter. There are several things you can do to help keep your home cool. Use towels or doorstops to block significant gaps in doorways, which can let in hot air. Invest in weather-insulating curtains that block out sunlight and the heat that comes with it. Consider not using the oven or dryer during the hottest parts of the day, as they create more heat in the building. Efficient Systems Consult with an HVAC maintenance professional to assess whether your system is the most efficient option for your home. Larger homes often benefit from ductless systems as they can create temperature zones throughout the residence, making it more energy-efficient than attempting to cool the entire house. An expert in AC replacement can inform you if your unit is the appropriate size for the area you wish to cool. In some cases, replacing your AC can help reduce your energy bills. Using The System Efficiently Constantly turning on the unit will raise your energy bills. Some people wait until the temperature is uncomfortable before turning on the unit. It has to kick into high gear to combat the high temperature and humidity levels, leading to higher bills and the need for a new AC installation sooner. Instead, set the unit to a specific temperature so it activates automatically. This way, the unit won’t have to work as hard to cool the space, leading to lower energy usage. When you’re away from home, raise the temperature by a few degrees to reduce energy consumption. Schedule a Maintenance Appointment with AJM Mechanical!
