5 HVAC Issues Commonly Seen in Historic Homes

Historic homes contain generations of stories and wisdom within their walls. However, they also contain problems especially common in older buildings. Learn about the five HVAC issues commonly seen in historic homes in Longboat Key, FL.

Poor Indoor Air Quality

We have come leaps and bounds in terms of building materials and air quality. Certain old building materials contain toxic materials, such as paint and lead, that can severely impact the indoor air quality (IAQ) in your home.

At Customer Air Inc., we offer indoor air quality (IAQ) testing services. We will test the quality of the air along with the negative impacts the different components of your HVAC unit have on your air quality, including ventilation and unit analysis. If tests reveal poor indoor quality, you can take action to improve the problem.

You can also improve air quality by removing toxins from the air, such as smoke, chemicals, dust and other debris. Thorough cleaning and a change of habits can improve indoor air quality greatly.


Old HVAC systems often generate a lot of noise thanks to loose components and ductwork or pipes. The noise can echo through the walls of the entire house, even late at night.

Do you hear the noise all the time or only when the HVAC system kicks on? Where is the noise the loudest? These details can help your HVAC service technician determine the cause of the noise to find the appropriate solution.

Air Leaks

Most HVAC systems use a building’s ducts to transport air throughout the house. If a hole appears in the duct material, the air will escape from the duct instead of going to the intended part of the room. The larger the hole, the more air will escape.

An air leak will prevent a room from reaching desired temperatures. Furthermore, an air leak will cause your HVAC system to run less efficiently.

Dirty Units and Ducts

Dust and debris can accumulate in your HVAC system. Get duct cleaning services in Longboat Key, FL, to remove the dust so that you can keep it out of your air and allow your unit to run more efficiently.

HVAC units require regular cleaning, too. HVAC maintenance involves cleaning the air filter and the exterior components. Your service technician will perform a complete inspection to make you aware of any foreseeable HVAC issues before they happen unexpectedly.

Old HVAC Units

Old HVAC units run inefficiently compared to energy-efficient modern units. HVAC units last 10-15 years before needing replacement. If you have an old HVAC unit, talk to one of our service technicians about new installation to learn more about new units available to you.

All AC units receive a SEER rating, which measures their efficiency. Most units fall within the range of SEER 13-SEER 23 with higher SEER ratings indicating the more efficient units.

Some new HVAC units have additional features, such as digital controls and smart thermostats, making it easier to customize and monitor your unit. The design of these features increases efficiency.
