3 Reasons to Change Your HVAC Filter

Tom Markley • March 30, 2021

Changing the filter in your HVAC system is a simple but crucial part of its maintenance routine. In fact, you should change it at least every 90 days and more often if you have pets or the filter looks gray and dirty. Doing so will help you avoid the following problems.


What Happens if You Don’t Change Your HVAC Filter?

1. Reduced Airflow

Air won't pass through a clogged filter easily, which means airflow around the whole HVAC system will be reduced. This forces the system to work harder, putting strain on components. If this happens for long periods, the equipment's lifespan will be diminished, and some parts may need premature repairs or replacements.

2. Frozen Evaporator Coils

Another consequence of low airflow is that warm air won't pass over the evaporator coils. The refrigerant inside may then become too cold, causing moisture along the coils to freeze. When this happens, refrigerant won't be able to absorb heat, and the HVAC will become less efficient. Additionally, the compressor may overheat and burn out.

3. Higher Energy Bills

When HVAC efficiency is reduced due to low airflow or frozen coils, the system has to run more frequently to reach the desired temperature. This could leave rooms in your home too hot or cold and lead to increased energy bills. Filters are inexpensive, and the cost of replacing them is much lower than replacing components or paying high bills.

If you’ve heard people talking about “new refrigerant rules” for air conditioners and heat pumps, you’re not alone. Homeowners are wondering if their current AC system is suddenly outdated or impossible to repair. The simple answer is no — you do not need to replace your air conditioner just because refrigerant rules have changed. What Changed With HVAC Refrigerants? The HVAC industry is moving away from higher-GWP refrigerants, including R-410A, and toward newer refrigerants with lower environmental impact. Under the EPA’s refrigerant transition rules, many new residential air conditioners and heat pumps manufactured after January 1, 2025 must use lower-GWP refrigerants. Existing systems can still be serviced, and parts used to repair existing systems are not subject to the same restrictions as new equipment. For homeowners, that means your current air conditioner or heat pump does not automatically need replaced. Can My Current AC Still Be Repaired? Yes. If your system uses R-410A, it can still be serviced. The bigger question is whether a repair makes financial sense. As older refrigerants become less common over time, certain repairs — especially refrigerant leak repairs — may become more expensive. That does not mean every older system should be replaced, but it does make the repair-versus-replace decision more important. When Should You Consider Replacing Your AC? You may want to consider replacement if: -Your system is over 10–15 years old -You are facing a major repair -Your AC has a refrigerant leak -Your energy bills keep climbing -Your home has uneven temperatures -Your system uses older equipment that is no longer under warranty If your system is newer, running well, and only needs a minor repair, replacement may not be necessary. Don’t Panic — Get Honest Advice The new refrigerant rules are a real change in the HVAC industry, but they should not be used to scare homeowners into replacing equipment before they need to. At Alpine Heating, Cooling, Plumbing & Refrigeration, we help homeowners understand their options clearly. Whether your system needs a simple repair, a refrigerant leak check, or a full replacement estimate, our goal is to give you honest information so you can make the best decision for your home.
