Emergency AC Repair Without Overtime Charges

Florida’s heat doesn’t take breaks, and neither do we. Our 24/7 emergency repair services ensure you’re never left sweating through a system breakdown, whether it happens at midnight on a weekday or during a holiday weekend. What sets us apart from other air conditioning companies is our unique pricing philosophy: “Straight time, all the time, no overtime.” This family-owned approach means you receive the same fair pricing whether we service your system at 2 PM on a Tuesday or 2 AM on a Sunday.

We service all major HVAC brands, including Carrier, Trane, Lennox, Rheem, Goodman, American Standard, York, and Mitsubishi.

This comprehensive brand expertise means we can quickly diagnose issues ranging from refrigerant leaks and compressor failures to electrical problems and thermostat malfunctions, regardless of your system’s manufacturer or age.

Complete Air Conditioning & Heating System Design and Installation

Installing a new HVAC system requires careful consideration of numerous factors including square footage, insulation quality, window placement, ceiling height, and occupancy patterns. Our in-house duct designer holds Wright Soft energy calculation certification, utilizing advanced load calculation software to determine the precise cooling and heating requirements for your specific space. This scientific approach ensures optimal system sizing, preventing the energy waste and comfort problems associated with oversized or undersized equipment.

We specialize in installing the greenest, most energy-efficient Carrier and Mitsubishi products available on the market today. Modern systems can achieve SEER ratings exceeding 20, potentially reducing cooling costs by up to 60% compared to older units. Variable-speed technology allows these systems to operate at different capacities based on demand, maintaining consistent temperatures while minimizing energy consumption and reducing humidity levels more effectively than single-stage units.

Preventative HVAC Maintenance and Kool Club Membership

Regular maintenance extends equipment lifespan, prevents unexpected breakdowns, and maintains peak efficiency throughout the system’s operational life. Our Kool Club Membership provides comprehensive preventative maintenance plans tailored to your specific equipment and usage patterns. During maintenance visits, we perform essential tasks including:

• Cleaning or replacing air filters to maintain proper airflow and indoor air quality
• Checking refrigerant levels and testing for potential leaks
• Inspecting electrical connections and tightening loose components
• Lubricating moving parts to reduce friction and wear
• Testing thermostat calibration and programming settings
• Cleaning condensate drains to prevent water damage and mold growth

Indoor Air Quality Solutions

Indoor air quality significantly impacts health, comfort, and productivity, particularly important in Florida’s humid climate where mold, mildew, and airborne allergens thrive. We offer comprehensive indoor air quality services including UV light systems that neutralize bacteria and viruses, whole-house dehumidifiers that maintain optimal humidity levels between 30-50%, and advanced filtration systems capturing particles as small as 0.3 microns.

These solutions prove especially valuable for households with allergy sufferers, elderly residents, or individuals with respiratory conditions. UV germicidal lights installed within your HVAC system continuously sanitize the air passing through, reducing illness-causing pathogens by up to 99% while preventing mold growth on cooling coils.

Commercial and New Construction Services

Commercial HVAC systems demand specialized expertise due to their complexity, size, and critical role in business operations. We provide comprehensive commercial services including rooftop unit installation and service, split system design, and building automation integration. Our new construction services begin during the planning phase, collaborating with architects and contractors to ensure optimal system placement, proper ductwork design, and seamless integration with building specifications. We offer free system estimates for any new or replacement home comfort equipment, helping you make informed decisions about your investment in comfort and efficiency.
