Downs Heating & Air Conditioning Frequently Asked Questions

How long will my heating and air conditioning unit last?

Heating and cooling systems can last anywhere from 10–20 years. The amount of time your system will last largely depends on how well you take care of it. If you have a maintenance plan for your system, and it is regularly maintained, its lifespan will be a lot longer than if you don’t take proper care of it.

How can I save money on my power bill?

In the summer months, set your thermostat to the highest possible temperature you are comfortable with when you are home, and turn it up or off completely when you are away. The same concept applies during the winter by setting your thermostat to a lower temperature.

Ideally, set your thermostat to 78°F during the summer and 68°F during the winter when you are home. Investing in a programmable thermostat can help you efficiently maintain the appropriate temperature when you are home or when you are away.

How often should I change my air filter?

The general rule is to change it once a month, unless otherwise specified on the particular air filter you purchased. If your home has a single occupant, or if mostly unoccupied, you can go for a longer stretch of time before changing it. However, if you have pets, or anyone living in your home with allergies, you may consider changing it more often, or using a more efficient filtration systems. Contact us today for more options.

Why is knowing the dew point important?

The dew point is a way of measuring the amount of moisture in the air. The higher the dew point, the more moisture is in the air. Relative to humidity, the dew point can never be greater than the outside air temperature. When the temperature inside is at or below the current dew point, condensation will begin to form. To avoid condensation forming on the windows of your home or business, pay attention to the weather forecast, particularly the dew point, and adjust your thermostat so that the inside temperature stays above that number.

Why do I need a system designed specifically for my home or building?

A well-tuned, customized heating and air conditioning system ensures that your home or business has a comfortable temperature and clean air. To do the job effectively and economically, the system must match the structure it is going into. Undersized system? Your heating and AC unit will have to work harder which will increase your monthly utility costs and shorten the life-span of your system. Bigger isn’t always better, either. A system that is larger than what you need will still raise the cost of your utility bill.
