Frequently Asked Questions

Rheem Pro Dealers meet manufacturer training, certification, and service standards that regular contractors don't. This status ensures proper system sizing, installation practices that preserve warranty coverage, and access to extended parts warranties. You're working with installers who've demonstrated technical proficiency directly to the equipment manufacturer.

Eastern Shore winters are mild enough for heat pumps to handle heating efficiently without backup systems in most homes. The humid summers increase cooling demand, making proper refrigerant charging and airflow balancing critical for comfort. Heat pumps outperform furnaces here because heating loads stay moderate and cooling needs dominate energy costs.

Compressor failure, refrigerant leaks in older refrigerant systems, or multiple component failures within two years usually make replacement more practical. Single-component issues like failed capacitors, thermostat problems, or reversing valve repairs are worth fixing. Age matters too—systems under 10 years typically justify repair, while 15-plus-year-old units facing major repairs rarely do.

Duct leaks in unconditioned spaces waste conditioned air before it reaches rooms, and undersized or damaged ductwork restricts airflow to specific areas. Closed or blocked vents, improper damper settings, and inadequate return air pathways also create pressure imbalances. Room-by-room temperature differences of more than three degrees usually indicate air distribution problems, not equipment failure.

Technicians recover existing refrigerant, check for leaks using pressure tests or electronic detectors, repair any leaks found, then add refrigerant to manufacturer specifications by weight or pressure. Simply adding refrigerant without finding leaks wastes money because the system will lose charge again. Proper charging also requires measuring airflow and verifying superheat and subcooling temperatures.

Twice-yearly service before cooling and heating seasons catches issues when repair costs are lower and prevents peak-season breakdowns. Spring maintenance prepares the system for humid summer cooling demand, while fall service ensures efficient heating performance through winter. Skipping maintenance allows refrigerant leaks, electrical wear, and airflow restrictions to reduce efficiency by 15-25% annually.

Restaurant and retail refrigeration failures cause immediate inventory loss, health code violations, and business closures that cost thousands per day. HVAC breakdowns create discomfort but rarely stop operations or spoil products. Compressor failures, refrigerant leaks, and evaporator coil issues need same-day diagnosis to prevent total product loss in walk-ins and display cases.

Technicians measure CFM (cubic feet per minute) at supply registers and compare readings to system requirements based on tonnage and duct layout. Adjustments involve repositioning dampers, sealing duct leaks, and verifying blower speed matches system design. Proper airflow prevents short cycling, improves humidity control, and ensures even temperatures throughout the space.

Seasonal inspections catch pressure drops, small leaks, circulator pump wear, and ignition problems before they cause no-heat failures. Flushing sediment, testing safety controls, and checking expansion tank pressure address issues that worsen during continuous winter operation. Most mid-season boiler breakdowns trace back to problems detectable during pre-season service.

Extended parts coverage protects against compressor failure, refrigerant leaks in coils, and component defects that typically appear between years 7-12 when standard warranties expire. Labor isn't covered, but parts represent 60-70% of major repair costs. This warranty transfers once if you sell the property, adding resale value.

Conditioned air escaping into attics, crawlspaces, or wall cavities never reaches living areas, forcing the system to run longer cycles to maintain temperature. A 20% duct leak rate can increase energy costs by 30-40% while reducing comfort. Leaks also draw in humid outdoor air, dust, and allergens that overwork filters and degrade indoor air quality.

Verify the thermostat is set to cooling mode and temperature is below current room temp, check that the circuit breaker hasn't tripped, and confirm the air filter isn't completely blocked. Outdoor unit should be clear of debris and running when the system calls for cooling. These account for 30% of no-cooling calls that don't require repair.
