HVAC Air Filters

A Complete Guide to HVAC Air Filters

Air filters may be small, but they’re essential to keeping your Rose City, Texas, HVAC system running smoothly and efficiently. Learn how HVAC filters work, find out what type you need, and discover when to replace them in this complete guide to HVAC air filters.

How HVAC Filters Work

First, it’s important to know what exactly air filters do and why they’re so important. Most offer two different levels of protection.

On one level, they act as protective shields for your heating and cooling system. That means filters work hard to trap dust, dirt, and other airborne particles before they enter your HVAC system. This helps to keep the inner workings of your HVAC system clean and prevents buildups that can damage your system or cause a breakdown.

In addition, most air filters also strive to protect your home’s indoor air quality. That means they can remove indoor pollutants and airborne particles that trigger allergy or asthma attacks. This helps keep your family healthy and clears the air in your home.

Common Air Filter Types

When you purchasing an air filter, you’ll get to choose among several common types. Most HVAC filters are disposable, which means you’ll use them just once. When their time is up, throw them out and replace them with a new one. Many disposable air filters are pleated and made of polyester, but others are made from fiberglass and don’t have pleats.

A select few air filters aren’t designed for single usage. Instead, they’re reusable, you’ll need to wash them between uses to remove the accumulated dust and debris. Take care to let these filters dry completely before reusing, or you could inadvertently introduce a mold or bacteria problem.

Standard HVAC Filter Sizes and Ratings

In addition to the variety of materials, HVAC filters come in a range of sizes and dimensions. Before purchasing, always confirm that the filter’s dimensions match your HVAC system’s requirements. You can’t trim down an overly large filter to fit with your HVAC system, and a filter that’s too small won’t do an adequate job of filtering particles.

At Thermacon Service Company, we also recommend checking the minimum efficiency reporting value (MERV) rating on each filter before purchasing. This rating indicates how effective the filter is at filtering out contaminants, and a higher number means more filtration power.

  • MERV 1-4: These filters provide minimal filtration and cost the least. Washable and disposable fiberglass filters often fall into this category.
  • MERV 5-8: These filters provide moderate filtration, but they aren’t adequate for all households.
  • MERV 9-12: These filters provide high-quality filtration and have pleats to capture as many contaminants as possible. They are ideal for most households
  • MERV 13-16: These high-efficiency filters provide excellent filtrations, but they’re often designed for industrial HVAC systems, not residential heating and cooling systems. Not sure if these filters work with your system? Call our team for expert advice.

When to Replace Air Filters

We typically recommend replacing your HVAC filter every three months, but there are several reasons why you may need to switch yours out more frequently. For instance, when your air conditioner runs constantly, such as during the summer, you should replace the air filter once a month to keep your HVAC system running smoothly. If you have pets or if any of your family members suffer from seasonal or year-round allergies, you’ll also want to replace the filter every month or two.

No matter how often you replace the filter, the process is relatively easy. First, turn off the air conditioner, heat pump, or furnace. Follow the printed directions to make sure you’re orienting it properly. Make sure that no gaps remain between the unit and the filter, and then turn the HVAC system back on to enjoy the clean, freshly filtered air. Be sure to note the date that you changed the filter and mark your calendar for the next replacement date.

More Efficient This Fall

4 Ways to Make Your Home More Efficient This Fall

In Port Arthur, Texas, fall is the ideal time of year to save energy at home, especially when it comes to your HVAC system. From programming your thermostat to sealing cracks and leaks, discover four ways to make your home more efficient this fall.

Program the Thermostat

When you switch from cooling to heating, don’t keep your temperature settings the same. Instead, the Thermacon Service Company recommends setting your thermostat to 68 degrees when heating. Don’t leave it set to 68 around the clock, though. If your family heads out for the day or goes to sleep around the same time every day, dial the temperature down by 10 degrees. Doing this gives your heating system a break and lowers your household energy consumption.

Schedule HVAC Maintenance

Whether you rely on a furnace or a heat pump to stay warm during the fall and winter, your system needs HVAC maintenance. Our team recommends scheduling a tuneup as early in the season as possible to keep your energy usage low throughout the season and to give our team a chance to identify any serious issues.

Consider an Upgrade

Getting as much life as possible out of your heating system might be smart for your budget, but this can seriously compromise your household energy consumption. New furnaces and heat pumps offer much better energy efficiency than do models that are 10 years or older, so it could be in your best interest to replace your old system. We recommend looking for a system with Energy Star certification, which means it meets or exceeds efficiency standards.

Seal Cracks and Leaks

The most effective way to make your home more efficient might be helping warm air stay inside while keeping cold air out. To do this, try adding weather-stripping around leaky windows and door frames and sealing cracks around your home’s foundation.
