HVAC FAQs

How often do I need to change my filters?
Different filters will vary in how often they need to be replaced. Thinner, less durable filters will need to attended to monthly, either by cleaning or replacing them. Pleated filters are more effective and can last a few months before needing to be replaced. Always check your filters each month to ensure that they are clear and able to protect your system.

What does SEER stand for?
SEER stands for Seasonal Energy Efficiency Rating. It’s found by taking the number of cooling units (BTUs) a system requires during the average cooling season and dividing it by the total watts-hour used over that time period. The better the SEER rating, the more energy efficient your system is.

What is the Heating Seasonal Performance Factor?
The Heating Seasonal Performance Factor, or HSPF, is the same as the SEER factor but for heat instead of cooling. By taking the amount of heat produced by your heat pump, in BTUs, and dividing it again by the watts-hour used during the heating season, you get your HSPF score. Look for heat pumps with an HSPF of around 13 for the most efficient HVAC system.

Will anything help control the humidity in my house?
Humidity is a problem in many areas. The best way to control excessive humidity is to have a system that runs longer at lower speeds. Variable speed air handling equipment runs at very low speeds, which keeps that air circulating against the cooling coil and removes much more moisture than conventional systems. At these low speeds, the variable speed motor uses much less electricity than conventional motors.

Can I plant near my outdoor unit to cover it up?
Any vegetation or garbage around the outdoor unit can attract unwanted pests, or grow into the unit, causing irreparable damage. It is best to garden away from your unit. If you wish to conceal your unit, try one of these DIY projects for attractively concealing your outdoor AC unit.

What sized system do I need for my home?
Size is extremely important. Many homeowners fall into the myth that a larger system, automatically yields better results. This is not the case. You need your system to be precisely the right size in order to ensure that all rooms are heated and cooled effectively but not too quickly. A system that is too large can heat or cool a room so fast, that the thermostat gives off a premature reading that the room has been properly heated, or cooled, when it hasn’t. Speak with a Butler HVAC tech to discuss the size of your home and its layout for the best possible fit.
