What Your Neighbors Are Saying About Us

Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Jesse came for my semi annual heating checkup. He was prompt, calling ahead to say he was on his way. He was very thorough and explained everything he did.

I highly recommend Ellis Air & Heat. Larry Hatley service Technician came out and checked the unit out. Larry is one of the most pleasant, delightful person to deal with.

What Air Filter Replacement Does for Your Home

Your air filter works continuously to trap dust, pollen, pet dander, and other airborne particles before they circulate through your living space or settle inside your HVAC equipment. A clean filter allows air to move freely through the system, which supports consistent temperatures, lower energy use, and cleaner air throughout your home. In Dallas, where spring allergen levels are high and summer heat runs long, a properly maintained filter makes a real difference in how your system performs and how comfortable your home feels. Replacing your filter on a regular schedule is one of the most cost-effective ways to extend the life of your equipment and avoid unnecessary repairs.

How to Tell Your Filter Needs Attention

Many homeowners are unsure how often to change their filter or whether their current one is doing its job. There are several signs that your filter may be overdue for a replacement.

Your energy bills have increased without a clear explanation.
Airflow from your vents feels weaker than usual.
You notice more dust accumulating on surfaces around your home.
Your system is running longer cycles to reach the set temperature.
You or your family members are experiencing more allergy symptoms or respiratory irritation indoors.
There is a stale or musty smell coming from your vents when the system runs.

If you are experiencing any of these issues, a clogged or worn filter is often the first place to look. Our technicians can assess your filter as part of a routine service visit and recommend the right replacement interval for your home.

What a Clogged Filter Can Do to Your System

Finding the Right Filter for Your HVAC Setup

Not all air filters are the same, and choosing the wrong one can be just as problematic as neglecting replacement altogether. Filters are rated on a MERV scale, which measures how effectively they capture particles of different sizes. A filter with too low a rating will not adequately protect your system or your air quality. A filter with too high a rating can restrict airflow if your system is not designed to handle it.

Basic fiberglass filters are inexpensive but offer minimal filtration and need frequent replacement.
Pleated filters offer a good balance of filtration and airflow and are suitable for most residential systems.
High-MERV filters capture finer particles including bacteria and fine dust, making them a strong choice for households with allergy sufferers or pets.
HEPA-style filters provide the highest level of filtration but require a compatible system to function properly.

Our technicians can help you identify the right filter type and MERV rating for your specific equipment and household needs, so you get the protection you are looking for without compromising system performance.

Frequently Asked Questions

How often should I replace my air filter?

Most filters should be replaced every one to three months, depending on the filter type, household size, pet ownership, and local air quality. Dallas homes run their HVAC systems heavily in summer, which can shorten replacement intervals.

Can I replace my air filter myself?

Yes, basic filter replacement is something most homeowners can do on their own. However, if you are unsure of the correct size or type, or if your system has accessibility challenges, a technician can handle it during a routine service visit.

What MERV rating should I use for my home?

For most Dallas homes, a MERV rating between 8 and 11 provides strong filtration without restricting airflow. Homes with allergy sufferers or pets may benefit from a higher-rated filter, but it is important to confirm compatibility with your system first.

Will a dirty filter affect my air conditioning in summer?

Yes. Dallas summers put significant demand on air conditioning systems, and a clogged filter makes that worse. Restricted airflow can cause the system to overheat, freeze up, or fail entirely during the hottest days of the year.

Does Ellis offer filter replacement as part of a maintenance plan?

Yes. Filter replacement is typically included or offered as part of our routine HVAC maintenance visits. Regular maintenance is the best way to keep your system running efficiently and catch small issues before they become larger problems.
