HVAC In Older Homes

7 HVAC Issues Common in Older Homes in Smithsburg, MD

September 29, 2021

Cooler weather is fast approaching, and it’s prime time for one of the more dreaded maintenance tasks: checking HVAC equipment. Homeowners often deal with minor and major HVAC problems, especially in older homes. Here are some common HVAC issues that are more prevalent in older homes in Smithsburg, MD:

Poor Indoor Air Quality

Many older homes have ductwork made of flexible, paper-like insulation. This ducting loses airflow over time and can result in dirty air inside the house.

When dirt accumulates inside your ductwork, it escapes into your home and lowers your indoor air quality. Moisture can also get into the ductwork and contribute to microbial growth. It’s crucial to make sure that your HVAC system is in good working order.

Aging HVAC Unit

Older homes often have inefficient old HVAC systems. Many older systems often experience problems such as clogged vents or temperature control issues. If your system is old, these problems can develop no matter how well you maintain your unit.

The result is higher energy bills and an HVAC system that breaks down more frequently, especially in seasons when you need it the most. If your HVAC system is at least 15 years old, you need to replace it.

Leaky Ductwork

Another common issue is leaky ducts in your home. These leaks cause air to escape from the system, leaving you with less airflow than you need. The leaks may appear in elbows and weak joints, and you may hear a hissing sound when your HVAC system is running.

The result is an ineffective heating system that keeps you uncomfortable and uses a lot of energy. You should address any leaks or cracks before you decide to replace your ductwork. Contact your local contractor for inspections and HVAC repairs.

Outdated Thermostats

The thermostat is what allows you to control the temperature in your home. Older homes often have outdated thermostats, which can cause issues.

While it’s tempting to use those old, decorative thermostats for their aesthetic value, you need to replace them. These types of thermostats don’t monitor temperature consistently and tend to be unreliable.

To solve this, you can upgrade to a programmable thermostat. A basic programmable thermostat lets you adjust the temperature and set it to turn on and off at certain times. It also gives the ability to control your home’s temperature remotely.

Poor Airflow

In older homes, airflow can be a big problem. The ductwork in older homes is often small or restrictive, particularly when it consists of thin, lightweight material. Poor airflow can cause a lack of ventilation inside the home.

The result is high energy bills and an uncomfortable indoor environment. If you have issues with the airflow in your home, make sure to contact a professional right away.

Lack of Zoning

In older homes, zoning is often an issue. Older systems are all or nothing — you can’t individually control the temperature in certain rooms.

That can cause overheating or freezing in certain parts of the house. It also means that you run your air conditioner or heater the entire time, which leads to higher energy bills.

Conflicts may arise among household members whenever they can’t adjust the temperature to their preference. The solution is installing a new control panel in your home.

Newer HVAC systems, like ductless mini-splits, have individual controls in certain parts of the house. These systems are more efficient and cost-effective.

Continuous Cycling

Another common issue is HVAC units that continuously cycle, even when there isn’t a problem. This often occurs in older homes, which don’t have the proper insulation to insulate against temperature changes. The result is that your unit will cycle more frequently, using more energy and resulting in higher bills.

In extreme weather, this can make your home unbearable. Cycling will make you uncomfortable, and it’ll cost you a lot of money.

If you want to reduce your energy bills, increase comfort and prevent HVAC problems in the future, upgrade your system. Your home will feel more comfortable, and you’ll save a lot of money. To learn more about HVAC maintenance and our other services, contact Hagerstown Heating & Cooling.
