Tips For Maintaining Your Home’s Heating And Cooling System

In the home, the HVAC system is generally the most expensive appliance. The unit provides both heating and cooling needed to keep everyone comfortable when the weather outside is not agreeable. With proper maintenance, units offer many years of dependable and efficient service.

While all air conditioning systems work in a fairly standard way to provide a cool environment in one’s house, there are options for keeping warm during the cold days of winter. Still, the maintenance required by the homeowner will remain basically the same, regardless of the method the system used to heat the home.

All forced air systems use a filter. This filter is usually easily accessible and should be checked at least once per month and replaced when dirty. At the very least filters should be changed once every three months. In addition to improving air quality inside the home, the filter protects the coils inside the unit from dirt and dust.

Systems that also provide air conditioning will have an outside unit as well as the one located inside the home. These units are exposed to dust, dirt and pollen. These materials collect in the coils reducing efficiency of the system. They can easily be removed using a gentle spray from a garden hose.

No matter the heat source, the system will require annual maintenance provided by a certified HVAC technician. The coolant levels in heat pumps and air conditioning systems are checked and balanced. Devices that burn fuel to create heat will have the burner cleaned and flame adjusted to ensure clean burning and efficiency. In addition, the device is checked for safety.

Maintenance of a heating and cooling system is needed to ensure it remains efficient and safe. Systems that are not serviced will lose as much as 10% efficiency each year. Most owners find the cost of a service call to be recovered in lower costs for utilities.

Routine Cooling System Maintenance Helps Prevent Costly AC Repair

When the cold days of winter pass, residents know it is just a matter of weeks before they will need to turn on the cooling to keep their homes comfortable. Just as one needs regular maintenance for his or her car, these systems also need maintenance. Without such service one may need costly AC repair.

Dirty Coils in a unit can prevent air flow so the unit cannot cool the home properly. Continuing to operate the cooling with dirty coils will make it work harder to cool the home and increase the cost of air conditioning. Unfortunately, the additional strain on the other parts can cause premature failure of the unit.

Air conditioners use coolant that is commonly called Freon to transfer heat. If the Freon levels are low, systems become less efficient and must work much harder. Eventually, they might not cool at all. In addition, these low coolant levels may cause the compressor to freeze and be permanently damaged.

Each time the thermostat turns on the compressor, it signals a relay switch. As this switch connects, a small electrical arc forms that can result in pitting of the contacts. Eventually these relays need to be replaced. The pitting may cause a drop in efficiency or the cooling to stop working altogether.

Air handlers pump large volumes of air through the cooling coils and into ducts. Leaks in the duct work can allow warm air from the attic to infiltrate the cooled air and reduce efficiency. In addition, particulate matter, in the form of dust, is increased and can cause coils to be more easily blocked by dirt.

One of the keys to prevent ac repair is regular maintenance. Small problems can be discovered and fixed before the unit fails. Having the unit inspected and maintained is a key to efficient operation.
