Heating/Furnace Repair & Maintenance

Some people think that their furnace needs to be repaired only when it stops working, but this is not necessarily true all the time. There are some telltale signs that show that your heating system badly needs repair. It may create strange sounds, which is not normal, since a furnace is usually quiet. There are times when you need to increase its thermostat or its pilot light is yellow, which means that carbon monoxide is starting to manifest. Moreover, your furnace may find it hard to stay on, and this can be caused by different issues. A furnace specialist can best diagnose whatever problems and do the necessary repairs before they worsen.

For a furnace to function efficiently and reach its maximum lifespan, it is crucial to have it maintained regularly. You should hire a certified HVAC professional to tune up our furnace once a year. This way, you can make sure that your furnace heats efficiently, it reaches its maximum lifespan, your energy bills are decreased and the possibility of carbon monoxide poisoning is reduced.

Heater/Furnace Replacement and Installation

When heating systems and furnaces are not properly installed, they will not work efficiently. They will use up more energy and require more repairs. As these units grow older, the costs of repairing them increase significantly. To avoid these costly repairs, it is recommended to replace units, which are ten years or older, with the latest energy-efficient models.

Cooling

When air conditioners cool the air, they subsequently dehumidify the air. Keeping excess moisture out of the home inhibits the growth of mold and mildew which can cause allergy symptoms and health problems when they release their spores into the air. Humidity can also cause damage to wood products and flooring in the house. However, humidifiers can also be helpful in keeping the air in your home or business moist enough to not irritate the comfort of all inside. Air that is too dry can irritate your throat and allergies.

Air conditioners work by using refrigerants that are easily converted back and forth from a liquid to gas state. Refrigerants cool the home by transporting warm air out of the house.

Air conditioning systems are comprised of three major parts which are the air compressor, the condenser and the evaporator. In central systems that are split, the compressor and condenser are contained in an outdoor housing unit while the indoor portion, the evaporator, is located indoors and is usually combined with the furnace. In the air conditioning cycle, the refrigerant first enters into the compressor as a warm low pressure gas. After it has been compressed, or has had its molecules squeezed together, it leaves the compressor as a high pressure hot gas.

The condenser receives the hot high pressure gas and is cooled by air that is blown by a condenser fan that pushes the air over finned condenser coils. This process causes the gas to be changed into a high pressure hot liquid which is then pushed onto the expansion valve.

The expansion valve receives the high pressure hot liquid into its small entrance and then releases it as a cooled vapor through an opening on the other side and into the evaporator coil.

The evaporator coil is met by warm air blown in from the home that subsequently heats it while the cold coil transfers the cooled air back into the home. As the refrigerant becomes heated again, it re-enters the cycle.

There are two main systems for air conditioning:

  • Central air conditioning systems are comprised of two units, the condensing unit and the evaporating unit. They are controlled by a thermostat located in the home and are usually piggy-backed onto a furnace.

  • Heat pumps are a combination heating and air conditioning system. They work by reversing a process that provides heat in the winter and cooled air during the summer according to thermostat control settings.

An air conditioning system is one of the most vital appliances. Maintenance checks for cooling should be performed each spring before the summer heat puts the system back to work, and maintenance checks for heating should be performed each summer before fall and winter. A trusted professional like Griesemer Plumbing & Maintenance can be trusted to provide expert care for the home's air conditioning system.
