 How often should I change or clean my filters?
Filters should generally be replaced every month when the system is running. Replace filters with the same kind and size as the original filter. If your filter is not disposable, follow the manufacturer instructions for cleaning.
If you're using a high-density filter such as an electrostatic filter, check with Ragsdale Heating and Air, who can raise the external static pressure of your system. If the external static pressure exceeds the design criteria of your system, it can negatively impact the performance and life of your equipment.
Where is my filter located?
Your air filter should be located in either the blower compartment of the furnace, in an attached filter case, or in a return air grille in a wall of your home. If you cannot find the air filter, contact Ragsdale Heating and Air for assistance.
What services need to be performed for planned maintenance on my heating and air conditioning equipment? How often should this maintenance be performed?
We recommend you have Ragsdale Heating and Air perform planned maintenance every 6 months on your heating and air conditioning system. Ragsdale Heating and Air maintenance agreements include reduced rates on labor and parts and provide priority response. Maintenance agreements include cleaning indoor and outdoor coils, tightening electrical connections, checking supply voltage and operating current, checking refrigerant charge, measuring temperature differential at supply and return registers, cleaning blower wheel and motor, inspecting and adjusting burner, checking heat exchangers, cleaning drain lines and pan, checking ductwork for leaks and insulation, and checking thermostat.
Should I cover my outdoor unit in the winter?
Covering the unit is not necessary. Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered.
How close to the outdoor unit should I plant shrubs or flowers?
Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need intake and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.
What are the average life expectancies for heating and air conditioning equipment?
The average expected life of an air conditioner is approximately 15 years. The average expected life of a heat pump is approximately 10 to 12 years, since it operates year round. The average expected life of a gas furnace or air handler may be longer. Units in corrosive environments, such as, but not limited to coastal installations, will tend to have shorter lives.
Is there any advantage to setting my thermostat fan to "ON" so the fan runs constantly?
Yes, there are a couple. The first is that you get constant filtering of the air in your home. The second is that because the air is moving, you have a more even temperature throughout the home. However, continuous fan mode during COOLING operation may not be appropriate in humid climates. If the indoor air exceeds 60% humidity or simply feels uncomfortably humid, it is recommended that the fan be used in AUTO mode.
I've heard a lot about new refrigerants. Do I need to think about them when buying a system?
We do not advise homeowners to choose home comfort systems based on the refrigerant they use. The Clean Air Act does not allow ANY refrigerants to be vented into the atmosphere. They must be reclaimed, recycled and reused.
Units using the current refrigerant, R-22, will always be serviced with R-22.
They will not need to be changed to a different refrigerant. The scheduled phase-out of R-22 allows for plenty of refrigerant to be available to service all cooling units and heat pumps that use R-22 for the life of the equipment. We do offer limited lines of high efficiency comfort systems using R-410A refrigerant. Our gradual introduction of these products has allowed servicers in the field the opportunity to adapt to the required installation and service techniques, to ensure homeowners continue to receive the comfort and value they have chosen.
As the HVAC industry gradually and confidently transitions to a new refrigerant, we encourage homeowners to maintain their focus on purchasing energy efficient home comfort products that best meet their comfort needs. Purchasing higher-efficiency air conditioning and heating systems and better sealing our homes will not only improve comfort and reduce energy costs, but will also improve our environment.
