Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.

Understanding The Role Of HVAC Filters In Preventive Maintenance

by Billie Carlson

If you're like most people who've recently purchased your first home, you probably already know that performing preventive maintenance will be an essential part of your new role as a homeowner — and your household HVAC system is no exception to this rule. One of the most important parts of your HVAC system is also one of the simplest — the filter. The role of an HVAC filter goes beyond the simple task of removing dust and debris from the air — it also acts as the frontline defense against various airborne particles that could potentially harm your system's functionality and efficiency.

Here's what you need to know about the role of your HVAC filter in terms of preventive maintenance:

The Protective Role of Filters

HVAC filters protect the system's vital components from dust, dirt, and other debris. When these particles build up over time, they can cause wear and tear to the internal mechanisms of your HVAC unit, resulting in decreased performance and possible system failure. Therefore, maintaining clean filters is a critical part of ensuring the overall health of your HVAC system.

The Connection to Indoor Air Quality

Apart from safeguarding the HVAC system's components, filters also contribute significantly to the quality of indoor air. By trapping various contaminants such as pollen, dust mites, and mold spores, HVAC filters prevent these particles from circulating in your indoor environment, contributing to a healthier and more comfortable space for you and your loved ones.

The Impact on Energy Efficiency

Unclean or clogged HVAC filters make your system work harder to maintain the desired temperature, resulting in increased energy usage. On the other hand, clean filters improve airflow, enabling the system to heat or cool your space more efficiently, ultimately saving on energy costs.

Regular Filter Maintenance

To reap the benefits of HVAC filters, it's crucial to incorporate filter maintenance into your regular preventive maintenance routine. This involves routinely checking the filters for any signs of dirt buildup and replacing them as necessary. You may need to change your filter every 1-3 months, depending on the usage, filter type, and indoor air quality.

Choosing the Right Filter

Various types of HVAC filters are available in the market, and selecting the right one is essential. Filters are rated based on a Minimum Efficiency Reporting Value (MERV) that indicates their ability to trap airborne particles. Higher MERV ratings mean better filtration. However, it's important to choose a filter that aligns with your HVAC system's specifications and your specific needs. 

Scheduling regular maintenance appointments with your local HVAC service and repair contractor can help ensure that your system operates at peak efficiency throughout the year.
