HVAC Breakdown – What is the Number One Reason?


The number one reason for HVAC breakdown is dirt. That’s right, dirt. Common types of dirt include dust, grime, filth and soil and they all contribute to the failure of your HVAC system. Although it is impossible to keep your home dust or dirt free, there are ways to keep the air quality in your home clean and comfortable. Understanding the impact of dirt on your HVAC system and your health is critical.

Dirt on Your HVAC System Causes HVAC Breakdown

Even a small amount of dirt can greatly impact your HVAC system. If your heating and air conditioning system is left un-checked or is not seasonally cleaned then the risk of failure significantly increases. As dirt builds up on the systems filter, the filter becomes blocked and air flow throughout your home is decreased. Systems with blocked air filters decrease in efficiency and put extra stress on the entire HVAC system. This in turn leaves your home feeling less comfortable especially during the hottest and coldest seasons.

Dirt can also cause potential mechanical breakdowns by infiltrating the HVAC systems motor. A clogged motor runs the risk of overheating the system leading to failure. When dirt gets into the sensors of your HVAC system then your heating or cooling units may fail to start because of a built in safety precaution. Contact Nelson Comfort, a trusted locally owned and operated company, for an HVAC inspection and cleaning.

The Impact of a Dirty HVAC System on Your Health

Breathing quality indoor air is critical to maintaining good health. Poor air quality can cause eye irritation, headaches, fatigue or allergies. Spending hours in your home breathing in dirty or germ filled air can cause yourself and loved ones to feel sick. Bacteria and viruses thrive in dirty HVAC systems. Your indoor air quality can be compromised if your HVAC system is not properly serviced. Having air ducts cleaned seasonally greatly improves your indoor air quality by keeping your HVAC system dirt free. It is essential to have your air ducts cleaned by a professional service provider who follows proper duct cleaning procedures. A provider that is inadequately trained can potentially cause more harm than good by releasing more dust, dirt and contaminants into the air or damage your heating and cooling system.

Preventative Maintenance Prevents HVAC Breakdown

You can improve the air quality of your home as well as extend the useful life of your heating and cooling system by performing seasonal HVAC service. This will insure that your system is running at peak operating conditions and will make it easier for the HVAC equipment to do its’ job. In order to avoid HVAC breakdown, you should service your HVAC system at least twice a year, once at the end of fall and once at the end of spring. Your home can have good air quality and continual year round comfort with regular HVAC service.

You can improve the air quality in your home by keeping your HVAC system cleaned and maintained. The parts of any heating and cooling system that should be regularly cleaned are: air ducts, vents and air filters. Dust, pollen and particles can be released in your home when air ducts are clogged with excessive debris. However, you can decrease the amount of dust in your home by having your vents properly cleaned. This can help prevent health hazards especially for people with asthma or allergies. Regularly replacing your HVAC air filters helps provide healthier indoor air quality free of pollen, allergens, and dust. The number one cause of heating and cooling system failures is clogged air filters due to dirt. For more information please visit Nelson Comfort.
