How often should I change or clean my filter?

Clean or replace your air filter regularly with pleated filters, every month if possible, particularly if you have pets in your home. A clogged filter restricts airflow and as a result your air conditioner will work longer to maintain the temperature. In addition to changing your filters regularly, it is recommended that your air ducts be cleaned every 5 to 10 years.

What setting should I set my thermostat on?

Set your thermostat lower in the winter and higher in the summer. According to the Florida Solar Energy Center, for each degree below 78 degrees Fahrenheit in the summer and above 68 degrees Fahrenheit in the winter, the energy usage in the home is increased by 10 to 12 percent. Find a comfortable automatic setting for your home thermostat and try to leave it there. Turning your thermostat off when you leave for work can be counter productive. You will spend more energy trying to re-cool your house than if you had not adjusted your thermostat in the first place.

When should I replace my air conditioner?

Air conditioners, like other machines, wear out over time and become inefficient. This results in higher electrical costs. If your system is more than 10 years old, contact us to find out how you can get a more energy efficient system.

What is the meaning of SEER?

SEER (Seasonal Energy Efficiency Ratio). The amount of cooling your unit, (air conditioner or heat pump), delivers per every electricity dollar spent. The higher the SEER rating, the more efficient the system.

Heat Pump vs Straight Cool?

A Heat Pump, a reverse cycle air conditioner, cools and heats by moving heat in or out of your home while a Straight Cool is an air conditioner which uses different sources for heating. It can work with natural gas, oil , an LP gas furnace, or electric furnace.

How often should I service my unit?

Your A/C unit should generally be serviced twice a year, around Spring & Fall to assure it is working at its peak performance. Call Riffle’s at (352) 429-8333 or simply email us here for our preventive maintenance inspections.

What does "Zoning" mean?

Zoning is a method of dividing a home into different areas and each area’s heating and air conditioning comfort is independently controlled. Therefore you can control the east side of your home along with the west side, and the third zone can take care of everything in the middle. If you have an upstairs then you can add a 4th zone.

How close should I plant shrubs near my outdoor unit?

Shrubs should not be closer than 18 inches to your outdoor unit. To operate efficiently the unit needs space to take in and blow out air. Also keep in mind that there is a service panel on your unit which must be accessible to the service technician if your unit needs to be worked on. There needs to be at least a 2 feet clearance in front of of this panel.

Why is one room in my home always too hot in the summer and what can I do to make that room more comfortable?

If the room has a large area of exposed glass, keep curtains or blinds closed during daylight hours, particularly at times when the sun would shine directly in. You might also ask your air conditioning contractor to check whether you are getting enough air in that room. There may be a problem with your duct system.

What do I do about my drain line?

Contact Riffle’s Air & Heat to receive the best instructions about your drain line and what to do to keep it clear.

On Friday, September 8, 2017, I went to flush my A/C’s drain line in preparation for Hurricane Irma. After the line was flushed I came inside to turn the A/C back on only to find my thermostat screen blank. As it was after hours and we had an impending hurricane coming, I didn’t want to pull one of your service techs away from his/her preparations. Within five minutes of my call your office called back, and in a very calm manner talked me through the steps needed to get my A/C back up and running. This is the second time one of your techs talked me through… an “emergency” situation. I cannot thank you enough for the help… and to your company for your ethical practice.
