One Checkup, Countless Benefits

Protect Your HVAC Systems with Expert Tune-Ups in the Rio Grande Valley

Discover the Key to Avoiding Costly Breakdowns with Regular HVAC Maintenance

Your HVAC system works hard all year to keep your home or business comfortable, but without regular checkups, even the best system can run into trouble. Dust buildup, unnoticed wear, and small inefficiencies add up fast, leading to costly repairs or breakdowns right when you need cooling or heat the most.

 

At L&S AIR LLC, our customized preventative HVAC maintenance solutions are tailored to meet the specific needs of the Rio Grande Valley residents. We focus on performance, efficiency, and longevity so your system runs smoothly all season long. Whether it’s your air conditioner, furnace, or entire HVAC system, a scheduled tune-up is the smartest way to safeguard your investment and avoid surprises.

Think Your HVAC Is Fine? Think Again

Just because it’s running doesn’t mean it’s running well.

Your HVAC system may seem like it’s working just fine, but beneath the surface, it could be wasting energy, straining its components, and affecting your indoor air without you knowing. Minor inefficiencies tend to go unnoticed until they turn into major repairs or full system failures. Here are some of the silent red flags you may be ignoring:

Home

Rising Energy Bills Without Increased Usage

If your monthly utility bills are climbing but your usage habits haven't changed, your HVAC system could be the reason. Dirty coils, aging parts, or a system in need of calibration can reduce efficiency and force your unit to work overtime, costing you more with every cycle.

Home

Inconsistent or Weak Airflow

Some rooms are colder, others warmer. That uneven comfort often points to hidden duct leaks, clogged filters, or an underperforming fan motor. These airflow issues mean your system is working harder to compensate, while you deal with frustrating temperature swings.

Home

Unusual Noises From Your System

That faint rattle, loud start-up, or persistent humming noise isn't just background static. Sounds like these usually signal problems with components like belts, motors, or bearings—issues that can worsen over time and lead to expensive breakdowns if ignored.

Home

Slow Heating or Cooling Performance

If your system takes longer to reach the set temperature, it's a clear warning sign. This often indicates clogged filters, low refrigerant, or deteriorating parts, all of which reduce performance and accelerate wear.

Home

Frequent Thermostat Adjustments

Constantly adjusting the thermostat to feel comfortable could mean your HVAC system is struggling to maintain balance. The issue might be due to an aging unit or a faulty thermostat.

Home

Declining Air Quality

Increased dust, dry air, or unusual odors may signal that your HVAC system isn't properly filtering or ventilating. Dirty ducts, clogged filters, or microbial buildup can compromise the air you and your family breathe.

Home

Lack of Routine Maintenance

If your system hasn't been serviced in over a year, it could be at risk. Regular maintenance prevents small issues from escalating, ensuring your HVAC system's efficiency, reliability, and longer lifespan.

Comprehensive HVAC Maintenance: Total Tune-Up, Zero Surprises

What’s included in our HVAC maintenance service—and why it’s worth every penny.

Thermostat Calibration & Settings Check

We make sure your thermostat is not only reading the right temperature but is also programmed for your comfort and energy efficiency. A quick tweak here can save you a lot in the long run.

Full System Inspection

Our technicians carefully inspect every component of your HVAC system—from the blower motor to the heat exchanger—identifying small issues early to prevent costly repairs down the line.

Air Filter Replacement or Cleaning

Clean filters are essential for both airflow and air quality. We'll replace clogged filters or clean reusable ones so your system runs smoother and your indoor air stays fresher.

Condenser & Evaporator Coil Cleaning

Dirty coils can strain your HVAC system, making it work harder, consume more energy, and wear out faster. By thoroughly cleaning the coils, we help your system run more efficiently, providing consistent and even cooling.

Electrical Component Check

Loose wiring or worn parts can lead to malfunctions or safety hazards. We test and tighten all electrical connections, capacitors, and relays to keep everything running securely.

Refrigerant Level Check

Low refrigerant levels can significantly hinder your cooling system's performance. Our team carefully inspects refrigerant levels and identifies any leaks, ensuring they're resolved before they compromise your comfort or increase your energy costs.

Drain Line & Pan Cleaning

Clogged drain lines lead to leaks, mold growth, and water damage. We clear them out and ensure your condensate pan is clean, helping you avoid hidden moisture problems.
