No matter what type of home service you’re paying for around the Winchester area, it’s essential that you know what to expect. The right information not only helps you make sure you are getting your money’s worth, but it will also prevent the likelihood that a technician will overlook critical areas.

HVAC systems are naturally intimidating to homeowners on account of their complexity. Today, we discuss 10 of the vital requirements of HVAC maintenance programs so you know what jobs you can expect the technician to do.

A routine visit typically begins with an HVAC technician checking thermostat settings.

Technicians check the thermostat for two primary reasons. First is to make sure the reading on the thermostat matches the actual temperature of the home. If there is a difference, this can indicate an issue with either the thermostat or the HVAC system that will need repair.

Second, if you have programmable thermostats, the technician may also opt to adjust the settings. This step helps the homeowner get the most out of their system as well as to help you save money on energy bills.

2. Visual Inspection.

Without visually inspecting the entire system, it’s easy to overlook trouble areas. Experts suggest that your HVAC system receives a thorough visual inspection at least once per year.

Although, during any routine visit, looking over all of the working parts can help the HVAC tech ensure your system is functioning correctly and anticipate future repairs that may be needed.

3. Inspecting/Replacing Filters.

A fundamental function of most HVAC systems is to preserve and maintain indoor air quality. Optimal indoor air quality is achieved with the use of air filters to keep dust and debris from polluting the home.

Over time, these filters will become dirty or blocked, which will result in poor indoor air quality. You can expect that the filters will be inspected, cleaned, or even replaced during routine HVAC system servicing.

4. Cleaning/Removing Debris.

Air filters are the first line of defense. Other parts of the system are bound to collect dust and debris over time. While this will reduce air quality, it can also pose a threat to the moving parts within the HVAC system.

During regular maintenance, an HVAC technician will clean the system, effectively removing as much of the debris as possible.

5. Inspecting Exhaust Outlets.

Debris removal goes beyond the preservation of air quality. The system’s exhaust outlets are responsible for allowing gases and toxins, such as carbon monoxide, to exit the home safely.

If debris build-up, preventing gases from being dealt with, the safety of those in the house is compromised.

During regular maintenance, it’s vital that the HVAC tech inspects the exhaust outlets, cleans out any unwanted debris, and performs any necessary repairs.

6. Lubricating Moving Parts.

HVAC systems feature a plethora of moving parts. These moving parts are responsible for several jobs, including airflow and temperature regulation.

Friction, debris, and rust can significantly reduce the system’s ability to function and may even prevent it entirely. Inspecting and lubricating the many moving parts throughout the system is a critical function of regular maintenance.

7. Electrical Connections.

HVAC techs aren’t electricians by trade but are trained to work on just about everything. Electrical connections in the HVAC system can deteriorate, become damaged, or even inadvertently disconnected over time.

Inspection and proper repairs of these electrical connections can not only ensure the system can function in its entirety but will also prevent significant damages from occurring that can result in costly repairs and replacements.

8. Fuel Lines and Connection Inspection/Repairs.

Proper containment of and fuel delivery is essential. If oil or gas leaks occur within the system, this can be a significant fire hazard.

When leaks occur, it is typically in the lines or on account of faulty connections. A thorough inspection of the fuel lines and relationships is a critical step taken with regular HVAC maintenance because of the potential dangers associated with faults in this area.

9. Checking Refrigerant Levels.

The primary role of the air conditioner is to bring down the temperature of the home. This is achieved by compressing refrigerant.

If the refrigerant levels are low, the system’s compressor will be overworked to reach desired temperatures within the home.

Overworking the system is a great way to decrease the lifespan of the compressor, which is why refrigerant levels will be checked and possibly addressed during maintenance.

10. Checking Condensation Drain.

Condensation drains are present to allow excess moisture to escape the system. Keeping moisture at a minimum reduces the likelihood of mold and bacteria developing within the system. It will also help bring down humidity levels of the home and can prevent corrosion.

During their visit, an HVAC tech will inspect to ensure the condensation drains present in the system are not clogged or in any way prohibited from performing their primary function.

Concluding Thoughts

Routine maintenance and repair calls are two very different things. During maintenance calls, some minor repairs may be done, but one cannot expect an HVAC tech to perform significant repairs if the damage is found during this visit.

There are plenty of factors that can prevent this from occurring, but any good technician will take the time to aid in setting up any future appointments that may be required.
