Comfort and Efficiency—No Ductwork Required
Whether you’re upgrading an older space or designing a new one, ductless heating and cooling systems offer unmatched flexibility. These sleek, high-efficiency units provide powerful temperature control without the need for ductwork, making them ideal for additions, garage conversions, small homes, or properties with room-by-room comfort needs.
Our team works with top-tier ductless mini-split brands and provides tailored solutions based on your layout, lifestyle, and energy preferences. Each installation is mapped with precision to ensure optimal airflow, minimal noise, and maximum energy savings. You’ll have complete control over your comfort and peace of mind, knowing your system was installed by local experts who do it right the first time.
Breathe Easier with Professional Duct Cleaning
Hidden behind your walls and ceilings, your air ducts can quietly collect years of dust, debris, and allergens. This buildup affects indoor air quality, reduces airflow, and forces your HVAC system to work harder, wasting energy and causing unnecessary strain on your equipment.
Our thorough duct cleaning service eliminates that buildup using high-powered vacuums and rotary brush systems designed to reach deep into your duct network. We remove dust, pet hair, mold spores, and other contaminants, leaving your air cleaner and your system more efficient. It’s an easy, affordable way to protect your comfort and extend the life of your HVAC equipment.
Engineered Airflow for Maximum Comfort
If your home suffers from uneven temperatures or poor airflow, it might be time to rethink your ductwork. A properly designed and installed duct system ensures air flows efficiently from room to room, minimizing energy loss and maximizing comfort.
We design and install ducts tailored to your home or business, not just based on square footage, but on how you actually use your space. Whether you’re building from the ground up or replacing an old, leaky system, we use quality materials, precise layouts, and professional sealing techniques to deliver superior airflow. It’s not just installation—it’s airflow engineered for comfort, performance, and long-term savings.
Fix the Flow, Feel the Difference
Even the best HVAC system can’t perform at its peak if your ductwork is damaged. Leaks, blockages, disconnected joints, or collapsed sections can all lead to uneven temperatures, rising energy bills, and poor indoor air quality. If your system struggles to keep up or certain rooms always feel off, your ducts might be to blame.
Our experienced team at L&S Air will inspect your entire duct network, pinpoint the exact problem areas, and make precision repairs that restore both comfort and efficiency. Whether it’s sealing joints, replacing crushed sections, or rebalancing airflow, we ensure your duct system is doing its job quietly and effectively, just the way it should. A smart repair now prevents bigger problems later and helps you get more out of your heating and cooling investment.
Tailored Heating Solutions That Last
When upgrading or replacing your heating system, you need more than a quick install—you need a system designed around how you live. That’s where we come in. We take time to assess your home’s layout, comfort needs, and energy goals to recommend the right fit, whether it’s a furnace, heat pump, or hybrid system.
Working with leading brands known for performance and durability, our installations follow industry best practices to ensure safe, code-compliant, and efficient operation. From proper sizing and equipment selection to clean installation and final testing, every detail is handled with care. The result? A new heating system that keeps your space cozy while keeping your bills in check for years to come.
Stay Ready for Every Cold Snap
A well-maintained heating system isn’t just more reliable—it’s safer, more energy-efficient, and far less likely to surprise you with a breakdown when you need it most. Whether it’s a quick tune-up before winter or a routine seasonal inspection, heating maintenance keeps your system performing at its best.
Our technicians follow a thorough checklist that covers everything from inspecting burners and heat exchangers to tightening connections and checking airflow. We make sure your system starts smoothly, runs cleanly, and operates efficiently—all while spotting issues early before they become costly repairs. Regular maintenance also protects your manufacturer’s warranty and helps extend the life of your heating equipment.
Don’t Let a Faulty Heater Leave You in the Cold
When your heating system breaks down—or even just underperforms—it can turn your home or business into a space you dread. Whether you’re hearing strange noises, getting no heat, or noticing uneven warmth, professional repair makes all the difference.
We run full diagnostics to identify the issue and fix it right the first time. From failing ignitors and blower motors to thermostat issues and airflow restrictions, we’ll restore your system’s function with speed and accuracy. And because we believe in doing what’s right, you’ll always get upfront estimates and honest recommendations—no upsells, no surprises. Just dependable heat, restored quickly.
Protect Your Comfort—and Your Investment
Your HVAC system works hard to keep you comfortable year-round. But without regular maintenance, small inefficiencies and hidden wear can quietly build into major problems. HVAC maintenance isn’t just preventive—it’s proactive care that saves you money, extends equipment life, and helps avoid unexpected breakdowns.
Our service includes a full inspection and tune-up of both heating and cooling components, tailored to your system’s age, condition, and usage. We clean coils, check refrigerant levels, inspect electrical connections, lubricate moving parts, and test system performance. You’ll enjoy better airflow, consistent temperatures, and a healthier indoor environment—all while lowering your energy bills. It’s peace of mind, season after season.
One Call, Complete Comfort Solutions
When your entire HVAC system isn’t working as it should—whether heating, cooling, or airflow—timely repairs are crucial. However, not all service teams have the skill or tools to handle complex issues across multiple components. That’s where we stand out.
We specialize in diagnosing and resolving full-system problems, from thermostat miscommunication and compressor failure to duct obstructions and electrical issues. Our goal isn’t just to get your system running—it’s to get it running right. We take the time to uncover the real root of the issue and repair it with precision, restoring total comfort and efficiency to your space. And with 24+ years of experience in San Juan, you can trust we’ve seen—and fixed—it all.
Smarter Temperature Control Starts Here
The thermostat is your HVAC system’s command center, and if it’s outdated or inaccurate, your comfort and energy efficiency take a hit. Whether you’re upgrading to a Wi-Fi model or installing a new thermostat as part of a complete system, choosing the right device (and having it installed correctly) makes a huge difference.
We help homeowners and business owners across San Juan select and install thermostats that fit their systems and lifestyles. From programmable and smart thermostats to basic digital controls, we walk you through the options so you don’t overbuy or under-optimize. Our team ensures precise calibration, clean wiring, and seamless integration with your HVAC systems. Want remote control via your phone? Need zoning capabilities? We’ll set it all up. The result is reliable comfort and lower bills without hassle.
When Comfort Slips, the Thermostat Might Be to Blame
If your system seems off—cycling too frequently, ignoring your settings, or delivering inconsistent temperatures, the problem might not be your furnace or AC at all. It could be your thermostat. And while it’s a small device, its impact is massive.
Whether it’s a wiring issue, miscalibration, dead sensors, or faulty communication with your HVAC unit, we troubleshoot with care and fix it with confidence. We also verify that your system responds correctly after repair, ensuring accuracy, reliability, and comfort. In many cases, we save our customers from replacing their entire system by identifying the thermostat as the true source of the issue. Quick fix, big payoff.
