An HVAC repair usually makes sense if the issue is minor or the system is under 10 years old. If your AC is older, struggles to cool evenly, uses R-22 refrigerant, or requires frequent repairs, replacement often makes more long-term sense, especially given the efficiency improvements in today’s units.
Most installations take 4–8 hours, depending on the system type, home layout, and any needed ductwork adjustments. Our knowledgeable team handles everything the same day, so you’re not stuck without cooling.
Warm air blowing from vents, strange noises, short cycling, high humidity, or a sudden spike in utility bills usually mean something inside the system needs attention.
Twice a year—one tune-up before summer and one before winter. Regular maintenance keeps your system efficient, helps eliminate breakdowns and prevent costly repairs, and extends equipment lifespan.
Yes. Mini-splits are perfect for rooms without ductwork, garages, sunrooms, FROGs, older homes with inconsistent temperatures, and commercial spaces. They offer impressive efficiency and zoned comfort without intrusive renovations.
A complete system inspection, cleaning, safety checks, performance tests, refrigerant level checks, electrical testing, and a written report. The goal is simple: catch minor issues before they turn into emergencies—and keep energy bills in check.
Leaky ducts can cause uneven temps, high bills, and overworked equipment. Sealing restores airflow, improves system efficiency, reduces dust, and helps maintain healthier indoor air.
Common signs include excess dust, lingering odors, allergies, sinus irritation, and uneven humidity. Air cleaners, HEPA filtration, UV lights, and whole-home humidity control can make a dramatic difference.
High-efficiency systems use less energy to achieve the same level of comfort. That means lower utility bills, quieter operation, and more consistent indoor temps. Many customers see a 20–40% reduction in energy use after upgrading.
Yes. Dunes Heating and Air Conditioning, LLC provides financing options (with approved credit) to make upgrading more affordable. Many homeowners use financing to get a better system now and pay gradually.
Most systems last 12–15 years. If yours struggles to heat, runs constantly, smells unusual, or needs frequent repairs, it may be cheaper in the long run to replace it with an updated high-efficiency model.
An air handler moves air across heating and cooling coils in an electric or heat pump system, while a furnace generates heat using gas. Dunes installs and services, depending on home needs.
Absolutely. Carbon monoxide is odorless and invisible. A quality detector is the only reliable way to protect your family—especially if you have gas appliances or a gas furnace.
Mini-splits use inverter technology that automatically adjusts output, so they don’t constantly turn on/off. This results in quieter operation, lower energy use, and better comfort.
It reduces excess moisture, helps prevent mold, protects wood floors, improves comfort, and takes stress off your AC system. In coastal climates, it’s often considered essential.
Both help reduce airborne bacteria, viruses, mold spores, and VOCs. UV lights disinfect surfaces inside the HVAC system, while plasma generators clean the air as it circulates.
Commercial equipment runs longer hours and handles larger spaces, so maintenance must be more frequent and detailed. Dunes provides custom plans based on building size, usage, and equipment type.
Sizing depends on square footage, insulation, window count, ceiling height, and sun exposure. Dunes Heating and Air Conditioning, LLC performs a complete load calculation—not guesswork—before recommending any system.
In most cases, a technician can be dispatched the same day, especially during peak seasons when AC or heat is critical. Emergency services are also available.
Hybrid systems combine an electric heat pump with a gas furnace. The system automatically chooses the most efficient fuel source for the current temperature—saving money year-round.
Smart and programmable thermostats prevent energy waste and help keep temperatures steady. Some homeowners save 10–20% on energy costs by switching.
