Systems & Equipment
An air conditioner only cools your home by removing heat and transferring it outside. A heat pump does the same thing for cooling, but can also reverse the process to heat your home in winter by extracting heat from outside air and bringing it inside. In Florida, heat pumps are popular because they provide both heating and cooling in one efficient system. While our winters are mild, a heat pump eliminates the need for separate heating equipment and is more energy-efficient than electric resistance heat.
Consider replacement if: your system is over 10-15 years old, repairs cost more than 50% of replacement value, your energy bills keep increasing, the system uses R-22 refrigerant (phased out and expensive), you have frequent breakdowns, or your home comfort is inconsistent. Consider repair if: the system is under 10 years old, it’s a minor repair (under $500), the system has been reliable, and you’re not planning to stay in the home long-term. We provide honest assessments and help you make the best decision for your situation and budget.
Proper sizing is critical and requires a professional Manual J load calculation. We consider: home square footage, insulation levels, window types and locations, ceiling heights, number of occupants, climate zone, sun exposure, and ductwork condition. Oversized systems cycle on/off frequently, don’t dehumidify properly, waste energy, and wear out faster. Undersized systems run constantly, can’t maintain comfort, and have shortened lifespans. Never rely on rules of thumb like “1 ton per 500 sq ft” – Florida’s climate requires detailed calculations. We provide free, accurate load calculations with every estimate.
No – bigger is not better! An oversized AC cools so quickly it shuts off before completing a full cooling cycle. This causes: poor humidity removal (short cycles don’t dehumidify), temperature swings and hot spots, increased energy bills (starting/stopping wastes energy), premature wear and shorter lifespan, and an uncomfortable, clammy-feeling home. In humid Florida, proper dehumidification is as important as cooling. A correctly-sized system runs longer cycles to remove both heat and humidity, keeping your home comfortable and efficient.
Single-stage systems run at 100% capacity until they reach the set temperature, then turn off. Two-stage systems have a low (65-70%) and high (100%) setting, running on low most of the time for better efficiency and comfort. Variable-speed systems can adjust output from 25-100% in small increments, providing: superior comfort (no temperature swings), better humidity control, quieter operation, 20-30% lower energy bills, and longer equipment life. While more expensive upfront, variable-speed systems pay back through energy savings and dramatically better comfort in Florida’s climate.
Maintenance & Repairs
At minimum, twice per year – spring AC tune-up before summer and fall heating tune-up before winter (or second AC check for Florida). For year-round AC use in Florida, many homeowners do quarterly checks. Professional maintenance includes: cleaning coils and components, checking refrigerant levels, testing electrical connections, lubricating moving parts, inspecting and cleaning drain lines, changing/cleaning filters, testing thermostat accuracy, checking ductwork for leaks, and measuring system performance. Regular maintenance prevents 85% of breakdowns, improves efficiency 5-15%, extends equipment life 3-5 years, maintains warranty coverage, and catches small problems before they become expensive. Our maintenance plans include priority service, discounts on repairs, and annual tune-ups.
It depends on filter type and your situation: Standard 1-inch fiberglass filters: monthly. Pleated 1-inch filters: every 1-2 months. 4-inch pleated filters: every 3-4 months. Media air cleaners: every 6-12 months. Check monthly regardless – if dirty, replace it! Change more frequently if you have: pets (hair clogs filters faster), allergies (need cleaner air), remodeling/construction (extra dust), Florida pollen season (spring/summer). A dirty filter causes: reduced airflow and cooling, higher energy bills (system works harder), frozen coils (restricted airflow), shortened equipment life, and poor indoor air quality. Filters are cheap ($1-5 for basic, $15-30 for better ones) – don’t skip them!
Common causes: Dirty air filter restricting airflow (check/replace immediately). Frozen evaporator coil (usually from dirty filter or low refrigerant – turn off system and call us). Low refrigerant from a leak (requires professional repair). Faulty thermostat or incorrect settings (check settings, replace batteries). Dirty outdoor condenser coil (prevents heat release – needs cleaning). Failed compressor or capacitor (requires professional repair). Blocked vents or closed registers reducing airflow. Ductwork leaks losing cooled air (30% loss is common!). If your system isn’t cooling, don’t let it run continuously – this can cause additional damage. Call us for same-day diagnostic service.
Refrigerant (R-410A in newer systems, R-22 in older) is the substance that absorbs heat from your home and releases it outside – it’s what actually cools the air. Refrigerant circulates in a closed loop and should never need “topping off” unless there’s a leak. Signs of low refrigerant: AC runs but doesn’t cool well, frozen indoor coil, hissing sounds, higher electric bills, and system short-cycling. Low refrigerant causes: poor cooling, frozen coils (can damage compressor), increased energy costs, and complete system failure. If refrigerant is low, there’s a leak that must be found and repaired – just adding refrigerant temporarily fixes it but wastes money. We use leak detection equipment to find and fix leaks, then properly charge the system. R-22 is phased out and very expensive; systems requiring it may be better replaced.
No! In Florida, we don’t have harsh winters, and covering your outdoor unit can cause more harm than good. Problems with covering: traps moisture, promoting rust and corrosion, creates home for rodents and pests, can damage fan if accidentally run while covered, and blocks drainage and ventilation. Your outdoor unit is designed to withstand weather year-round. The only time to consider covering: if you won’t use it for months (rare in Florida), cover only the top to prevent falling debris, and never cover sides (must have ventilation). For heat pumps (used year-round), never cover! Better protection: keep area clear of debris, trim plants 2-3 feet away, hose off leaves/dirt periodically, and schedule annual maintenance.
Efficiency & Performance
SEER2 is the new testing standard that became mandatory in 2023. It uses updated, more realistic testing conditions that better reflect real-world performance. SEER2 ratings are typically 4-5% lower than old SEER ratings for the same equipment. For example, a system rated SEER 16 under old standards might be SEER2 15 under new standards – but it’s the same equipment with the same actual efficiency. When comparing systems, make sure you’re comparing SEER2 to SEER2, or old SEER to old SEER. The new standard helps consumers make better comparisons and sets a slightly higher minimum efficiency bar.
EER (Energy Efficiency Ratio) measures cooling efficiency at a specific outdoor temperature (95°F), useful for comparing performance in hot weather. Higher is better. HSPF/HSPF2 (Heating Seasonal Performance Factor) measures heat pump heating efficiency. Minimum is HSPF2 7.5, with high-efficiency systems reaching 10+. Higher is better. AFUE (Annual Fuel Utilization Efficiency) measures furnace efficiency as a percentage. 80% AFUE = 80% of fuel becomes heat, 20% lost. High-efficiency furnaces are 90-98% AFUE. In Florida, SEER/SEER2 is most important since we cool year-round. HSPF matters for heat pumps during winter months. We help you understand what ratings matter most for your specific situation.
Yes! Smart thermostats typically save 10-15% on cooling and heating costs through: auto-scheduling (adjust temps when you’re away or asleep), geofencing (adjust when you leave/return home), learning your preferences and optimizing schedules, remote control (adjust from anywhere), energy reports showing usage patterns, and integration with humidity and air quality sensors. In Florida where AC runs year-round, that’s $150-300+ annual savings. The best part: most smart thermostats cost $200-300 and pay for themselves in 1-2 years. We install and configure smart thermostats to work perfectly with your HVAC system, and can show you how to maximize savings.
Installation & Cost
Full system replacement typically ranges: Basic efficiency (SEER 14-15): $5,000-$8,000 for 2,000 sq ft home. Mid-efficiency (SEER 16-18): $7,000-$11,000. High-efficiency (SEER 19-21): $9,000-$14,000. Premium systems (SEER 22+, variable-speed): $12,000-$18,000+. Cost factors include: equipment efficiency and features, home size and layout, ductwork condition (repairs add $1,500-$5,000), removal/disposal of old system, electrical upgrades if needed, permits and inspection fees, and warranty coverage. Beware of quotes that seem too good to be true – cheap installations often use undersized equipment, skip load calculations, reuse old parts, or use inexperienced installers. Quality installation is as important as quality equipment. We provide transparent, detailed quotes with no hidden fees.
Typical timelines: Straight AC or heat pump replacement (no ductwork): 1 day (6-8 hours). Full system with ductwork modifications: 2-3 days. New construction or complete ductwork: 3-5 days. Mini split installation: 4-8 hours per zone. Factors affecting time: accessibility of equipment, ductwork condition and modifications needed, electrical upgrades required, permit inspections, and home size/complexity. We work efficiently but never rush quality. A proper installation includes: load calculation and sizing, careful equipment handling, proper refrigerant charging, thorough duct sealing, complete testing and commissioning, debris cleanup, and customer training on operation. Same-day emergency replacements available for qualifying situations.
Yes! We understand HVAC replacement is a significant investment. We offer: Multiple financing options through leading lenders, 0% interest plans for qualified buyers (6-60 months depending on amount), low monthly payment plans, special seasonal promotions, flexible approval criteria (many programs available), same-day approval process, and no prepayment penalties. Many customers choose financing because: it makes high-efficiency affordable now (immediate energy savings), it avoids depleting emergency savings, it spreads costs over time, and energy savings often offset monthly payments. We also accept: cash, checks, all major credit cards, and offer senior and military discounts. Visit our financing page for current offers and to apply online.
New HVAC systems typically include: Manufacturer’s parts warranty: 5-10 years standard (register within 90 days!), extended warranties available to 12+ years. Compressor warranty: Often 10 years (the most expensive part). Labor warranty: 1-2 years from us on our installation. Workmanship guarantee: We stand behind our work. Important: Warranties require: proof of professional installation, timely registration with manufacturer, and proof of annual maintenance (required for some extended warranties). Extended warranty considerations: Covers labor costs (parts warranties don’t cover labor after year 1), no deductibles or service call fees, transferable to new homeowner (increases home value), and peace of mind for 10-20 years. We offer comprehensive maintenance plans that keep your warranty valid and your system running optimally. Always read warranty terms and keep documentation.
Yes, several available: Federal Tax Credits (Inflation Reduction Act): Up to 30% of cost (up to $2,000) for qualifying high-efficiency systems (SEER2 16+ for AC, 8.0+ HSPF2 for heat pumps). Heat pump installations may qualify for up to $2,000. Valid through 2032 with potential extension. Utility Rebates: FPL and LCEC offer rebates for high-efficiency systems – typically $50-300 depending on efficiency. Available seasonally – we track current programs. Manufacturer Rebates: Seasonal promotions offering $200-$1,000 back on qualifying equipment. Sales Tax Exemption: Florida sometimes offers sales tax holidays on Energy Star appliances. Requirements: Professional installation (DIY doesn’t qualify), equipment must meet minimum efficiency standards, must be primary residence, and proper documentation required. We help you identify all available incentives and provide necessary documentation. These incentives significantly reduce the net cost of high-efficiency systems.
Indoor Air Quality & Comfort
Florida’s high humidity requires proper dehumidification beyond just cooling. Common causes: Oversized AC cools quickly but shuts off before dehumidifying (most common problem in Florida!). Poorly sealed ductwork bringing in humid outdoor air. No whole-home dehumidifier (often needed in Florida). Short cycling (system turns on/off frequently). Insufficient return air causing poor airflow. Solutions: Proper AC sizing (longer run cycles = better dehumidification), whole-home dehumidifier ($1,500-3,000 – worth every penny), duct sealing and testing, smart thermostat with humidity control, and improved insulation/air sealing. Target indoor humidity: 40-50% for comfort and mold prevention. A dedicated dehumidifier is often the single best comfort upgrade for Florida homes.
Essential for Florida homes: Whole-home dehumidifier (critical for mold prevention – 90% of homes benefit), MERV 11-13 air filters (capture allergens, pollen, mold spores), UV air purifiers (kill mold, bacteria, viruses on coils and in air – $600-1,200), media air cleaners (hospital-grade MERV 16 filtration – $800-1,500), and regular duct cleaning (removes accumulated mold, dust, allergens – every 3-5 years). Also consider: ERV/HRV for fresh air exchange, bipolar ionization for advanced purification, and smart humidity monitoring. Florida’s climate creates challenges: high humidity promotes mold growth, sealed homes trap pollutants, year-round pollen and allergens, and AC runs constantly recirculating air. Investing in IAQ products prevents health problems, reduces allergies, protects your home, improves sleep and comfort, and extends HVAC life. We offer free IAQ assessments.
No! This is a common myth that actually costs money and damages systems. Your HVAC is balanced for specific airflow. Closing vents causes: increased pressure in ductwork (can cause leaks), reduced airflow causing frozen coils, unbalanced system working harder, increased energy use (not decreased!), uneven temperatures and hot/cold spots, and potential equipment damage. Your system moves a specific amount of air – closing vents doesn’t reduce that, it just forces air to go elsewhere (often through duct leaks). Better ways to save energy: Use a programmable/smart thermostat, seal ductwork properly (30% leakage is typical!), improve insulation, close blinds during hottest parts of day, and consider a zoned system (properly designed zones with dampers and multiple thermostats). If you want different temperatures in different areas, ask us about zoning systems or mini splits – the right solution, not closing vents.
Emergency & Troubleshooting
Quick troubleshooting steps: 1) Check thermostat – set to COOL, temperature below room temp, display working (replace batteries). 2) Check circuit breaker – reset if tripped (if it trips again, call us immediately – electrical issue). 3) Check air filter – replace if dirty/clogged. 4) Check outdoor unit – ensure it’s running, no debris blocking it. 5) Check vents/registers – ensure they’re open and unblocked. If none of these work, call us. Don’t: Keep running a malfunctioning system (can cause more damage), try to repair refrigerant or electrical yourself (dangerous and illegal without license), pour drain cleaner in condensate line (can damage PVC), or ignore strange sounds/smells (call immediately!). We offer 24/7 emergency service for complete breakdowns. In Florida heat, AC breakdowns are emergencies – we prioritize same-day service.
