No Heat in an Old Missouri Home

Recently, our team was called out by a homeowner facing a concerning problem. His St. Charles home had no heat.

This homeowner lived in one of the older homes. His three-story house on Clark St. was built way back in 1891! Back when this home was first built, there wasn’t anything close to the central heat and air systems we have today.

FUN FACTS: In 1891, Benjamin Harrison was the U.S. President.

Back in the 19th century, most homes were heated by wood-burning fireplaces and stoves. Even with this heat source, many homes would be literally freezing on the inside during our cold Missouri winters.

We quickly dispatched one of our licensed heating repair technicians to come out to his St. Charles home. Our technician discovered the cause of the problem was a bad capacitor.


What is a Capacitor?

A capacitor is an electrical component that stores and releases electrical energy in an electronic circuit. In the context of a heating system, capacitors are often found in the blower motor and compressor of the HVAC system.

A capacitor stores energy and provides the push needed to start the motor or compressor. Once the motor or compressor is running, the capacitor continues to provide a small amount of energy to keep it running smoothly.

no heat because of bad capacitor with the furnaceIf a capacitor goes bad, it can cause various issues with the heating system. For example, if the capacitor in the blower motor is faulty, the blower might not start or might not operate at the correct speed. This can result in reduced airflow through the heating system, leading to decreased efficiency and potentially uneven heating in different parts of the home.

If the capacitor in the compressor of an air conditioning system is faulty, the compressor might struggle to start or fail to start altogether. This can lead to a lack of cooling in the home during hot weather.

Fortunately for this homeowner, our Indoor Comfort Team technician was able to replace the bad capacitor and get the arm air back on again! If you have a furnace or other heating problem, call on us at (314) 230-9542 for quick heating repair service!


How Maintenance Can Prevent a Broken Furnace

Sometimes breakdowns and issues can happen with no warning and may not be preventable. But fortunately, that is not usually the case. Homeowners have a great opportunity to help make sure their home’s heating and cooling systems work well for many years.

Q: How can homeowners extend the life of their heater and prevent breakdowns?

A: With regular maintenance.

A bad capacitor in an HVAC system can lead to reduced efficiency, uneven heating, and potentially a complete failure of the system to operate. If there are signs of a bad capacitor, it should be inspected and replaced by a qualified technician. That will ensure the system operates safely and efficiently.
