Goodman 2.5 Ton 13.4 SEER2 R-32 AC Only With Vertical Coil
This listed package combines the Goodman GLXS3BN3010 condenser (2.5 ton, 13.4 SEER2, R-32) with the CAPTA3026B3 vertical coil. The components are presented as an AC-only system requiring a blower or furnace to form a complete conditioned-air setup. The coil is designed with corrosion-resistant aluminum and grooved tubing to increase heat transfer efficiency.
Key features noted by the manufacturer include factory helium pressure testing, pre-charged condenser for a limited tubing length, accessible service valves and gauge ports, and a 10-year parts warranty on the condenser. The vertical coil design suits installations where airflow connections and cabinet orientations match vertical configurations. Installers should verify furnace/blower compatibility, refrigerant charge, and system line lengths to ensure optimal performance.
QwikProducts Foaming Coil Cleaner For AC Unit
QwikProducts markets an industrial-strength, no-rinse foaming coil cleaner formulated to break down dirt, dust, grease, and oil on evaporator and condenser coils. The foaming action clings to vertical surfaces and fins, lifting contaminants without requiring aggressive mechanical scrubbing.
The product is promoted for broad use cases—residential central AC, rooftop units, refrigerators, and auto radiators. Because it is no-rinse, it reduces the need for extensive water access during maintenance, though technicians often follow specific service practices to flush loosened debris from drain pans and condensate lines. The cleaner’s alkaline detergent base suits grease and oil removal, but users should follow safety directions for protective gear and avoid mixing with other chemicals.
OUMSIS Air Conditioner Professional Foam Cleaner (2 Pack)
The OUMSIS aerosol foaming cleaner emphasizes a high-density foam and a reverse-flow valve that permits upside-down or angled application. This design helps reach deep evaporator coils and confined spaces common in window units, PTACs, and automotive HVAC systems.
Manufacturers claim improved airflow and heat-transfer performance after cleaning, with foam capable of clinging to vertical surfaces and lifting embedded grime. An included flexible extension tube aids precision application. For technicians and homeowners, this product is presented as a portable option for periodic maintenance, particularly where power rinsing or full disassembly is impractical.
Cenipar Double Sided AC Coil Cleaning Brush
The Cenipar brush is a manual cleaning tool with stiff bristles on one side and softer bristles on the other, intended for safe and effective removal of debris from evaporator and condenser fins. The dual-bristle design targets both heavy buildup and delicate fin structures without bending or damaging fins when used correctly.
Brushes are typically used in combination with chemical cleaners: foam loosens grime, and the brush dislodges particulates for subsequent rinsing or vacuuming. This tool is applicable to HVAC technicians and DIYers servicing window units, split systems, refrigerators, and heat pumps. Proper technique and gentle pressure are important to avoid fin deformation.
BOJACK 1 Poles FLA 40 Amp 24 VAC Contactor
The BOJACK listed item is a definite purpose contactor rated for FLA 40 Amp with a 24 VAC coil, commonly used as the switching device for outdoor condensers and compressors. While not a refrigerant coil, the contactor’s coil is the electrical actuator that engages the compressor and fan circuits.
Replacement contactors are often part of routine repairs when HVAC units fail to start or when relay chatter, pitting, or stuck contacts are observed. Key considerations include matching the pole configuration, current rating, and coil voltage to the original component. Proper wiring and safety precautions are essential during replacement to prevent electrical hazards.
Buying Guide: Choosing And Maintaining AC Heater Coils
This guide covers the main considerations when selecting replacement coils, cleaning products, tools, and electrical components that affect coil performance and system reliability.
1. Matching Coil Type And Size
- Vertical vs. Horizontal Coils: Verify cabinet orientation and airflow path. Vertical coils fit furnaces/blowers configured for upright airflow; horizontal coils are for side-access configurations.
- Capacity Compatibility: Match the coil’s tonnage and internal volume to the condenser’s rated capacity to ensure correct refrigerant charge and performance.
- Refrigerant Type: Ensure the coil and condenser use the same refrigerant (e.g., R-32 in the listed Goodman condenser) and are compatible with system pressures.
2. Materials And Heat Transfer Characteristics
- Tube And Fin Material: Aluminum fins and grooved tubing often provide good heat transfer and corrosion resistance for many residential applications.
- Construction Quality: Look for manufacturer testing (pressure tests, quality control) and corrosion-resistant coatings if you are in coastal or corrosive environments.
3. Installation And System Integration
- Professional Verification: A certified HVAC technician should confirm proper airflow, refrigerant line sizing, TXV or fixed orifice compatibility, and system charge after coil replacement.
- Accessories And Hardware: Ensure you have necessary gaskets, mounting brackets, and refrigerant line connections; mismatch can cause leaks or reduced efficiency.
4. Cleaning Products: Chemical vs. Mechanical
- Foaming Cleaners (QwikProducts, OUMSIS): Good for dissolving grease and lifting grime from tight fin packs. No-rinse formulas reduce water needs but still require debris management in drain pans.
- Manual Tools (Cenipar Brush): Useful to dislodge stubborn debris after chemical treatment. Use care to avoid fin deformation—work along fin direction with light pressure.
- Safety And Compatibility: Check cleaner pH and manufacturer recommendations for coil materials and nearby painted surfaces. Use protective equipment and follow disposal guidelines for runoff.
5. Electrical Components And Controls
- Contactor Selection (BOJACK): Match pole count, FLA rating, and coil voltage (e.g., 24 VAC) to the unit. Underrated contactors can overheat; overrated contactors may not fit mechanically.
- Signs Of Wear: Faulty contactors often cause intermittent starting, humming, or failure to engage. Regular inspection reduces downtime.
6. Maintenance Frequency And Performance Metrics
- Inspection Intervals: Check coils and filters at least twice a year; high-dust or greasy environments may require quarterly checks.
- Performance Indicators: Reduced airflow, rising delta-T across evaporator coil, longer run times, or increased energy consumption indicate coils or airflow obstructions need attention.
- Preventive Actions: Regular filter changes, fin straightening, coil cleaning, and ensuring proper condensate drainage extend system life.
7. Comparison Perspectives
- Replacement Coil vs. Cleaning: If a coil is damaged, corroded, or has failed tubes, replacement is necessary. Routine cleaning restores performance for most fouled coils.
- DIY vs. Professional Service: Simple cleaning and brush use can be DIY for accessible coils, but refrigerant-handling, coil replacement, and electrical component swaps should be handled by licensed technicians.
- Short-Term Savings vs. Long-Term Efficiency: Choosing cheaper cleaners or skipping preventative maintenance can increase energy costs and lead to premature component failure. Investing in compatible, quality coils and regular maintenance often yields lower lifecycle costs.
8. Safety And Environmental Considerations
- Chemical Handling: Wear gloves and eye protection when applying coil cleaners. Avoid inhalation of aerosols and ventilate workspaces.
- Runoff Management: Contaminated rinse water may carry oils and particulates—contain and dispose according to local regulations.
- Electrical Safety: De-energize equipment before accessing contactors or working near energized parts. Verify the 24 VAC control circuit is isolated.
