It depends on your filter type, home environment, and lifestyle. Most standard air filters should be changed every 1–3 months, but homes with pets, allergy sufferers, or high dust levels may need monthly changes. Skipping replacements can strain your HVAC system and reduce indoor air quality. If you’re unsure, Radiant Plumbing & Air Conditioning can inspect your current filter and recommend a schedule that fits your home. We even offer maintenance plans to help you stay on track year-round.
The “best” filter really comes down to what your home needs. If you’re focused on allergy relief or reducing airborne particles, high-efficiency filters like HEPA or electrostatic options may be ideal. For general household use, pleated filters offer strong performance at a reasonable cost. Radiant’s technicians can help you choose the right filter based on your HVAC system, indoor air quality goals, and budget—so you’re not left guessing at the hardware store.
Yes—and it happens more often than homeowners realize. A clogged or dirty air filter restricts airflow, forcing your HVAC system to work harder. This added strain can reduce efficiency, increase energy bills, and even cause parts to wear out faster. Over time, neglecting your air filter could lead to costly repairs or system failure. Radiant offers regular inspections and filter replacements to keep everything running smoothly—and your air clean.
They sure do. Many modern smart thermostats include reminders to change your air filter based on time intervals or usage. Some even track system performance and alert you if airflow becomes restricted. Radiant installs and configures smart thermostats that integrate with your HVAC system, helping you automate filter maintenance and avoid guesswork. If you’re looking for a tech-savvy way to keep your air clean, we can help you get set up.
We treat your air quality like it’s our own. Whether it’s replacing a single air conditioner filter or recommending the best air filters for your home’s long-term health, Radiant Plumbing & Air Conditioning brings expert care and honest recommendations to every visit. Our technicians are experienced, courteous, and committed to doing the job right the first time. With 24/7 availability in both Austin and San Antonio, we’re here when you need us—no pressure, just clean air and great service.
When was the last time you changed your air filter? For most homeowners, it’s easy to forget—until the sneezing starts or your HVAC system begins acting up. But your air filter plays a critical role in protecting both your home and your health. From reducing allergens to boosting HVAC efficiency, a properly selected and regularly replaced filter is one of the simplest ways to improve indoor air quality.
At Radiant Plumbing & Air Conditioning, we help homeowners in Austin and San Antonio choose the best air filters for their home, HVAC system, and lifestyle. Whether you’re dealing with constant dust buildup, seasonal allergies, or just want to protect your system from unnecessary wear and tear, our team can help you find a filter that fits your needs—and keep it on a consistent maintenance schedule.
Air filters are located inside your HVAC system, typically where the return air duct meets the unit. Their job is to trap particles like dust, pollen, pet dander, mold spores, and even bacteria as air cycles through your system. Without a filter—or with one that’s clogged or outdated—those contaminants are circulated right back into your living spaces.
Besides cleaning your air, filters also prevent debris from collecting inside your HVAC equipment. This helps your system run more efficiently and reduces the risk of breakdowns. When you combine clean air with optimal system performance, your home stays more comfortable and your utility bills stay more manageable.
Not all house air filters are created equal. Some are basic fiberglass filters that need frequent replacement, while others—like pleated filters, electrostatic filters, or HEPA filters—offer higher filtration and longer lifespans. But it’s not just about filtering power: you also need to consider compatibility with your HVAC system. Using a filter that’s too restrictive can actually reduce airflow and strain the system.
Our licensed technicians can walk you through the options and help you understand the MERV rating system, which measures how effectively a filter traps particles. For most homes, a filter rated between MERV 8 and MERV 13 offers a strong balance of performance and system compatibility. We can also upgrade you to a whole-home air filtration system for even better results—especially if someone in your household suffers from asthma or allergies.
Over time, dirty filters become clogged and block airflow. This forces your HVAC system—whether it’s your air conditioner, heat pump, or furnace—to work harder just to move air. That added strain leads to higher energy bills, inconsistent temperatures, and potential breakdowns. It can even cause frozen coils in your AC or overheating in your furnace.
If you’ve noticed weak airflow, more dust around your home, or rising energy costs, your air filter may be the culprit. We often discover during AC repair or furnace diagnostics that a neglected filter is at the root of the problem. That’s why we always check filters during routine HVAC maintenance visits—and recommend setting reminders for monthly inspections.
At Radiant, we believe every homeowner deserves clean, breathable air. That’s why we offer more than just quick filter replacements. Our air quality experts can assess your entire HVAC system, recommend better filter options, and even help with upgrades like UV air purifiers, whole-house filtration, or smart thermostats that send automatic filter alerts.
We also clean and seal ductwork to make sure your clean, filtered air actually gets to where it’s needed. Duct leaks or buildup can undo the benefits of a high-quality air filter by recirculating dust or reducing system performance. If your system is overdue for maintenance, our team can bundle duct cleaning and filter service for a full refresh.
For homeowners who want to set it and forget it, we also offer filter delivery programs and maintenance plans that include filter inspections and replacement. It’s a simple way to keep your HVAC system efficient—and your air fresh—without adding another item to your to-do list.
