You may find it challenging to efficiently heat your older home if there are pre-existing problems with the HVAC system. These problems can affect your comfort and health as well as increase your utility bills. Here are six HVAC issues to look out for in older homes in Hillview, KY.

Poor Indoor Air Quality

Older home designs may have gaps that allow air contaminants such as dirt, dust and pollen to enter inside. The buildup of these air contaminants can lead to health problems and lower indoor air quality. In addition, allowing outdoor air to enter your home can affect the humidity inside and lead to discomfort.

When cold outdoor air leaks inside your home, your HVAC system works longer to heat your home, leading to higher energy usage and costlier utility bills. Replacing your doors and windows with energy-efficient units and replacing air filters will help lower your energy bills. You can also seal any gaps around windows and doors where air may leak in or out of your home to prevent air pollutants from entering.

Poor Airflow

Air ducts help to supply warm air throughout your home. However, an older house may have damaged or leaking air ducts that affect proper airflow. This leads to cold and hot spots in your home and can encourage the growth of biological contaminants.

Ensure that you have your ductwork properly maintained to promote proper airflow. Cleaning the ducts will prevent the buildup of dirt, dust, allergens and biological pollutants. This also improves the efficiency of your HVAC system.

Outdated Thermostats

Thermostats help to regulate the temperature in your home. A faulty or outdated thermostat can lower the efficiency of your HVAC system by increasing wear and tear and leading to frequent cycling. This will also increase your utility bills and lower your indoor comfort.

Modern thermostats have various capabilities that help improve your system’s efficiency and save energy. Programmable thermostats can learn your heating preferences and even create heating zones in your home. Smart thermostats have Wi-Fi capabilities and allow remote access when you are not in the house.

Aging HVAC Unit

Your home may have an aging HVAC system that is over 15 years old. Additionally, the previous owner may have failed to perform annual maintenance, lowering its efficiency and shortening its lifespan. The HVAC system will consume more energy while operational and take longer to heat your home.

You may have to replace your HVAC unit with a new one to improve your home comfort. An outdated system may also affect your indoor air quality, leading to health problems. Replacing your system with the help of a professional will ensure that you get the right size system with capabilities for zoning and better energy efficiency.

Unusual Noises and Unpleasant Odors

It’s normal for your HVAC system to make some noise while it’s operational. However, if the system in your old home makes loud and unusual noise due to aging, broken components and lack of regular maintenance, this can affect your comfort, especially while trying to sleep at night.

Your system may also produce unpleasant odors due to the presence of biological contaminants. Water leaks in your system encourage the growth of biological contaminants, which produce a musty smell. Electrical issues and gas leaks can produce unpleasant smells from your HVAC system as well.

Replacing the HVAC system will keep your older home at optimal comfort levels and safe you money with improved energy efficiecy. You will eliminate unpleasant odors and weird noises in addition to preventing frequent and costly repairs to keep an aging system running.


Leaks in your older home may indicate a broken piece of condensation pipe or drain. Clogged drains can also cause leaks, leading to water damage or musty smells. Qualified HVAC technicians can fix the condensate drains to help protect your home.
