Air Conditioning

What can I do to reduce my air conditioning costs?

Make sure to schedule your preventative maintenance. With a Shumate home maintenance plan, you'll lower your monthly utility bills by having a more efficient HVAC system.

More importantly, a maintained system dramatically lengthens the life of your equipment, saving you thousands of dollars by not having to prematurely replace your system.

Should I repair, or replace my HVAC unit?

If you plan to move in the near future, repair is often the best choice when it's feasible. However, if you plan on staying in your home, it's wise to invest in an energy efficient A/C -heat pump system that has the capacity to cool your home efficiently and cost effectively.

The investment could save you thousands of dollars over time, not to mention create a much better living environment for you and your family!

How often should I change my filter? 

This really depends on what kind of filter is being used, and how much you use your system.  Usually, you want to change your filter at least every three months – but if you are using a high efficiency filter, then it only needs to be changed every six months to twelve months.

What temperature should I set my thermostats to?

The best answer is to set them for what ever temperature keeps you comfortable and the utility bills manageable. The real concern in the home is usually humidity, keeping it high enough in the winter and low enough in the summer both for personal comfort and to retard mold and mildew.


Why is my upstairs so much warmer and drier than my downstairs?

The simple answer is that heat rises – so that even the warm air your downstairs system generates moves upstairs gradually. And, all that warm air tends to dry things out – from your leather furniture to your nose! There are some options that might help the flow of warm air in the house, and a humidifier will remedy the dryness problems associated with winter and heating.

How can I reduce my heating costs in the winter?

Make sure to schedule your preventative maintenance. A maintained system dramatically lengthens the life of your equipment, saving you thousands of dollars by not having to prematurely replace your system. Shumate Comfort Customers enjoy pre-season preventive maintenance check-ups twice a year. They're also entitled to other benefits like priority service and special discounts.

Air Quality

How does air quality affect our home?

Humidity that is too high or too low, plus airborne particles and pollutants like dust, mold and animal dander contribute to poor indoor air quality. 

This makes family members who suffer from asthma, allergies or other respiratory ailments more vulnerable.

Does a dehumidifier make a difference?

Yes! Dehumidifiers reduce excessive levels of moisture (humidity) in your home's air.

Too much humidity makes you feel uncomfortable, usually making your home feel hot and sticky, requiring you to keep your thermostat lower, resulting in much higher utility bills.


I am getting less and less hot water from my shower. Why?

As a water heater ages, it builds up material in it that gradually impairs its ability to heat water. So, while a water heater might still “work” – it works less and less well, and less and less efficiently, as it gets older.

How much money will a higher SEER system save me?

The higher the SEER the more you can save but at a certain level the cost saved does not always reflect in the cost of the system. The cost needs to be decided based upon how long a customer is going to live in a home, the need for additional comfort, such as less humidity, quieter operation, cost of operation, initial cost and other factors come into play in the decision.
