Water Heater Problems Expansion Tank

Water Heater Repair & Installation

If you are receiving cold water in your house, the source of the problem may be a broken gas burner. To resolve the problem, our team of certified plumbers will perform an inspection of the orifice in your water heater to confirm it’s clogged. Next, we will check the thermocouple to confirm it’s operating. 

If you have an electric water heater, the cause of the cold water may be related to a malfunctioning heating element. Our staff has the tools necessary to replace a broken orifice or heating element. Our licensed plumbers offer trustworthy water heater repair and replacement services to homes in Maryland, Pennsylvania, and Delaware. Give us a call by phone at (302) 367-7915 to schedule an appointment. We offer excellent warranties on our HVAC and plumbing services.

Furnace Repair & Replacement Services

Prior to the beginning of the winter season, it’s crucial to add oil to the blower motor in your furnace. Our licensed technicians will remove the access panel and inspect the blower motor in your furnace. Next, we will remove the blower motor at the base of your furnace and lubricate it. To prevent damage to parts, our team will add oil to the ports of your blower assembly. We offer reliable furnace repair and installation services and are committed to customer satisfaction.

Our contractors provide HVAC repair services in areas such as Wilmington, Upper Darby, Easton, and Ardmore. Once a technician arrives at your house, the gas burners will be checked to confirm they are safe to use. Since the furnace is not operating in the summer, a combination of dust and dirt will collect on the burners. If the flames in your burners are yellow, this is a sign of debris in your furnace. Our team of certified contractors will use a commercial vacuum cleaner and other tools to remove dirt from the gas burners and other parts in your furnace. Give our staff a call at (302) 367-7915 to become familiar with our furnace repair solutions.

Heat Pump Repair & Maintenance Services

Although a heat pump is engineered with a long life cycle, there are a couple of problems you may encounter. Ordinary types of problems include strange noises, low airflow, and refrigerant leaks. If the distribution of air in your home is weak, the technicians at ServiceMark will check your air filter to see if it’s contaminated with dirt, dust, hair, or bugs. We will replace your air filter to restore the flow of warm and cold air. 

In addition, our staff will remove debris from the fan to ensure incoming air is being circulated from your heat pump to your air ducts. If your heat pump is circulating warm air in the summer, this is an indicator of a refrigerant leak. Our team will inspect the refrigerant pipes connected to the pump for cracks and holes. We will replace damaged refrigerant pipes and refill the refrigerant to keep the air in your home cold. 

Our maintenance services for heat pumps includes an inspection of the reversing valve. We will check the valve to confirm if your heat pump is efficiently producing warm and cold air. We offer fast and safe HVAC repair services to homeowners in locations such as Drexel Hill, Elkton, Newark, and Conshohocken. Give our staff a call by phone at (302) 367-7915 to receive assistance.

Heat Pump Maintenance

Air Conditioning Repair & Replacement

If your air conditioner is not removing heat and humidity from your house, this is a sign of dirty or damaged condenser coils. The coils are engineered to release heat energy into the outdoor air. Once the condenser coils are broken, the central air conditioner will be unable to dispose of the heat from your home. The team of technicians at ServiceMark will disassemble the system and check the coils. 

If we discover cracks or contamination, we will replace or clean the condenser coils. In addition, we will analyze the drain pipes to ensure they are not clogged. Once the drain in your air conditioner becomes clogged, the excess moisture will cause damage to electrical parts. We offer credible air conditioning services to households in areas such as Elkton, Ardmore, Wilmington, and Newark. To confirm you are prepared for the summer, we will inspect your evaporator coils, thermostat, drain pipes, air ducts, and condenser coils to ensure your air conditioner is operating properly.
