What our Experts Think

• Efficient Year‑Round Comfort with Modern Refrigerant
  The Goodman GLZS5BA1810 1.5 Ton Heat Pump Split System delivers 15.2 SEER2 cooling and solid heating capacity (~18,000 BTU) using R‑32 refrigerant, helping lower both your energy use and environmental impact compared with older refrigerants.

• Reliable Single‑Stage Performance
  Its single‑stage scroll compressor provides dependable, consistent cooling and heating for smaller homes or zones without complex modulation or expensive controls—ideal for straightforward comfort.

• SmartShift® Defrost for Quiet Heating
  Built‑in SmartShift® defrost technology helps ensure heating cycles are quiet and reliable in cold weather, minimizing frost buildup and interruptions in performance.

• Durable Weather‑Resistant Construction
  The unit features a heavy‑gauge galvanized‑steel cabinet with powder‑paint finish and louver guard, protecting components from rain, corrosion, and harsh outdoor conditions for long‑term reliability.

• Service‑Friendly & Installer‑Ready
  Factory‑installed components like suction‑line accumulator, crankcase heater, high‑capacity muffler, and service valves with gauge access help HVAC pros install and maintain the system efficiently.

• Quiet Operation You’ll Appreciate
  With a typical sound level around 70 dBA, this heat pump delivers cooling and heating without excessive noise, making it suitable for suburban homes or quiet residential settings.

Q&A

• Change Air Filters Often – Check and replace your indoor air filter every 1–3 months to maintain strong airflow and protect coils from dust and debris. Dirty filters can drastically reduce system efficiency and comfort.

• Keep Outdoor Unit Clear – Regularly remove leaves, grass clippings, and other debris around the condenser to ensure proper airflow and prevent blockages that reduce SEER2 performance.

• Clean Coils Annually – Both outdoor condenser and indoor evaporator coils should be cleaned at least once per year by a professional to maintain efficient heat transfer and avoid frozen coils.

• Inspect Refrigerant Lines & Insulation – Ensure R32 lines are intact, well‑insulated, and leak‑free; proper refrigerant conditions are critical for heat pump efficiency and capacity.

• Check Drain & Fan Components – Periodically clean the condensate drain line and pan to prevent clogs and check outdoor fan blades for debris or damage.

• Maintain Unit Clearances – Trim vegetation and maintain ≈ 2 ft of space around the outdoor unit so airflow isn’t restricted during operation.

• Schedule Professional Tune‑Ups Bi‑Annually – Have a licensed HVAC technician service the system before cooling and heating seasons to check pressures, electrical connections, reversing valve operation, and overall performance. This helps preserve SEER2 efficiency and prolong equipment life
