What is a SEER rating?

The SEER (Seasonal Energy Efficiency Ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems.

For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, 15, or higher. The higher the SEER rating, the more energy efficient the system will be. In order to maintain the efficiency of a system, you must have it inspected and serviced on a regular (1-2 times per year) basis.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal (Definition: in name only, no number value) SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is derived based on the combination of equipment installed in the home.

The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in determining the final, total rating.

Why should I have regular maintenance? How often should I have it performed?

Your heating and cooling systems work incredibly hard to perform their functions for your home every day. Their constant stopping, starting, and continual operation can wear down any machine if the proper care and maintenance is delayed.

By performing regular maintenance, you can maximize the lifecycle of your heating and/or cooling unit, and guard against common equipment failures. Regular equipment maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires, and corroded electrical contacts that the untrained eye may not notice.

You should have maintenance done on your system regularly (twice per year, Spring/Summer and Fall/Winter) to ensure maximum efficiency, and prevent possible problems that may occur in the future.

What equipment requires regular maintenance

At least once a year, heat pumps and air conditioners require a professional tune-up.

Gas-fired equipment functions with better efficiency, so they only need to be serviced once per year.

Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank, and the parts of the actual furnace and coiler.

Heat pump and air conditioning unit inspections should include the fan, compressor, indoor coils, outdoor coils, line sets, and refrigerant lines.

What are the advantages of a programmable thermostat?

Since they are electric, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats, you can control the temperature in your home at different times of the day, without ever touching your thermostat. Everything is automatic, so you will never forget to change the setting on your own.

Until the seasons change, and then you may want to change your automatic settings.

What type of air filter should I use? How often should I replace it?

Standard filters work to keep your system and its' ductwork clean, but they don't improve indoor air quality significantly. For that, we recommend a media filter.

The media filter rests between the main duct return and the blower cabinet. It improves that dust and particle removal by seven times that of a standard filter. Upgrading to a media filter will help remove everything from the air, from insecticide to airborne viruses.

Always chose a filter that matches your blower's capacity. For optimum efficiency and filtration, Glenmont Heating & Air Conditioning recommends that you replace your disposable filter at least once a month, especially if you have animals in the home. If you have washable filters, they should be cleaned once a month.

Of course, if you have any questions, please feel free to contact the office, or speak to your technician at your next service call.
