How Often Should I Service My HVAC System?

If you live in North Texas, your HVAC system doesn’t get much of a break. Between triple-digit summer heat, high humidity, sudden cold snaps, and the occasional winter freeze, your heating and cooling system works hard nearly year-round. One of the most common questions we hear at Selective Air is: “How often should I service my HVAC system?” The short answer: at least twice per year. But the more important answer is that regular maintenance is what keeps your system from breaking down when you need it most.

At Selective Air, our mission is built on integrity, honesty, and professionalism. That means we’re not here to sell you services you don’t need, but we’re here to help you protect your investment, avoid emergency breakdowns, and keep your home comfortable in every season.

The Recommended HVAC Service Schedule

For homes in North Texas, we recommend:

Spring maintenance for your air conditioning system.
Fall maintenance for your heating system.

Because our climate pushes systems to their limits, twice-yearly service is the best way to ensure performance, efficiency, and reliability.

Why Twice a Year?

Unlike milder climates where HVAC systems may sit idle for months, North Texas systems often transition directly from cooling to heating with very little downtime. That continuous use increases wear and tear on components like:

Compressors
Blower motors
Capacitors
Electrical connections
Refrigerant lines
Heat exchangers

Routine maintenance catches small issues before they become expensive problems.

Why HVAC Maintenance Is So Important in North Texas

1. Extreme Summer Heat

North Texas summers are intense. When outdoor temperatures climb into the upper 90s and beyond, your air conditioner may run for hours without stopping. That constant strain can lead to:

Overheated components
Refrigerant issues
Dirty coils are reducing efficiency
Electrical failures

If your system hasn’t been serviced, it’s much more likely to fail during peak heat, when HVAC companies are at their busiest. Maintenance prepares your system before the heat hits and helps ensure you are cool throughout the warmer seasons.

2. Sudden Winter Freezes

Texas winters can be unpredictable. A mild December can suddenly turn into a deep freeze overnight and out of nowhere. Heating systems that haven’t been tested may fail when temperatures drop below freezing.

Common winter issues include:

Ignition failures
Dirty burners
Cracked heat exchangers
Faulty thermostats
Heat pump malfunctions

A fall tune-up ensures your heating system is safe and ready for cold weather.

3. Humidity and Air Quality Challenges

North Texas humidity can impact indoor comfort and system performance. Poor airflow, clogged filters, and dirty coils can contribute to:

Mold growth
Musty odors
Reduced efficiency
Increased energy bills

Routine service helps protect both your system and your indoor air quality.

What Happens During HVAC Maintenance?

When you schedule service with Selective Air, we don’t just give your system a quick glance. We perform a thorough inspection and tune-up to keep it operating efficiently and safely.

Air Conditioning Maintenance Includes:

Checking refrigerant levels
Inspecting and cleaning condenser coils
Testing capacitors and electrical components
Inspecting the compressor
Cleaning drain lines
Checking thermostat calibration
Measuring airflow

Heating Maintenance Includes:

Inspecting burners and ignition systems
Checking heat exchangers for cracks
Testing safety controls
Inspecting blower motors
Checking electrical connections
Ensuring proper airflow

Our goal is not just to maintain your system, but to strengthen it against future breakdowns.

How Maintenance Prevents Breakdowns

Most major HVAC failures don’t happen randomly. They develop over time.

For example:

A weak capacitor that goes unnoticed can eventually fail, shutting down your AC during a heat wave.
A clogged drain line can cause water damage or a system shutdown.
Dirty coils force your system to work harder, increasing wear and reducing lifespan.
Loose electrical connections can lead to system failure or safety risks.
Routine maintenance identifies and corrects these small problems before they turn into emergency repairs.

At Selective Air, we believe in fixing issues early, not waiting until they become costly.

How Maintenance Saves You Money

Some homeowners hesitate to schedule maintenance because they see it as an extra expense. In reality, maintenance is one of the most cost-effective decisions you can make. Here’s how it saves money:

Lower Energy Bills: A clean, properly tuned HVAC system runs more efficiently. Dirty coils, clogged filters, and worn components make your system work harder and use more electricity.
Fewer Emergency Repairs: Emergency breakdowns often cost significantly more than routine maintenance. Preventive service reduces the risk of sudden failures.
Longer System Lifespan: Well-maintained systems can last years longer than neglected ones. Replacing an HVAC system is a major investment, and maintenance protects that investment.
Maintains Manufacturer Warranty: Many HVAC manufacturers require proof of regular maintenance to keep warranties valid.

Signs You May Need Service Sooner

While twice a year is standard, certain signs mean you shouldn’t wait:

Rising energy bills
Uneven temperatures
Weak airflow
Strange noises (banging, grinding, squealing)
Musty or burning smells
Frequent cycling on and off
The system is struggling during hot afternoons

If you notice these issues, it’s best to schedule service promptly to prevent larger problems.

Maintenance vs. Emergency Repairs

There’s a big difference between planned maintenance and emergency service. Maintenance is proactive. It prepares your system for the demands of North Texas weather. Emergency repairs are reactive. They happen when something has already failed. While we’re always ready to help in an emergency, our goal is to reduce the chances that you’ll ever need one.
