Don't Let a Broken AC System in Ocean City, MD, Steal Your Summer
There's a cruel irony to an air conditioner that picks the hottest week of the year to break down. In Ocean City, MD, where July temperatures regularly combine with humidity indexes that push the "feels like" reading past 105°F, a failed cooling system is a health concern. Custom Mechanical dispatches certified service technicians with fully stocked vehicles to tackle everything from blown capacitors and refrigerant leaks to compressor failures and frozen coils. We don't patch problems; we solve them, so Ocean City homeowners can stop sweating the small stuff and get back to enjoying the season.
Fight Back Against Salt Air With HVAC Maintenance in Ocean City, MD
Ocean City's greatest asset, its location, is also your HVAC system's greatest adversary. Salt air accelerates corrosion on condenser coils, electrical contacts and refrigerant lines at a rate that inland homeowners never experience. Left unchecked, this kind of environmental wear quietly chips away at system efficiency, drives up energy costs and shortens equipment lifespan by years. Custom Mechanical's air conditioning service visits are specifically designed to address coastal wear, including thorough coil cleaning, corrosion inspections, electrical connection testing and refrigerant level verification.
Schedule a Whole-Home Heating and Air Conditioning Evaluation
Many Ocean City, MD, property owners, especially those managing vacation rentals or recently purchased homes, have no clear picture of the condition of their HVAC system. Aging equipment, mismatched components, undersized systems and deteriorating ductwork all contribute to comfort problems that aren't always obvious until something goes wrong at the worst possible moment. Custom Mechanical offers comprehensive heating and air conditioning evaluations that provide property owners with a complete, honest assessment of their system's current performance, efficiency and expected lifespan.

Responded to no heat call on system less than 10 years old that was running but failing to reach setpoint. Upon arrival, performed diagnostic testing using digital multimeter to measure system voltage and amperage. Initial voltage reading showed 35.42V at blower motor assembly, indicating potential low voltage issue. Further testing revealed amperage draw of 179.8A, which is significantly elevated and indicative of a locked rotor or failing motor condition. Inspected interior components including copper refrigerant lines, electrical connections, blower motor housing, and wiring harnesses. Found blower motor drawing excessive current while attempting to operate, causing system to run continuously without adequate air circulation to satisfy thermostat demand. The elevated amperage reading confirmed motor failure, preventing proper heat distribution throughout the space.
