HVAC is an acronym for Heating, Ventilation and Air Conditioning. HVAC is most often used to depict the whole heating and cooling system consisting of the duct work, air filters, humidification controls, and registers.
What regular maintenance can I perform for my
Locate the label on the outer surface of the equipment for a manufacture date. If the equipment is less than five years old, it should have a warranty. Warranty terms and conditions change by manufacturer and the installing company. American Air & Heat can help you verify the warranty status of your heating and cooling system.
How do I know if my older working
AC unit needs service?
Does your AC make strange noises? Is it cooling or heating all areas of your home adequately or taking longer to cool down or heat up? Have your utility bills been rising in spite of no rate increases from the power company? These are signs that you may have an AC problem that needs service. Keep in mind, the longer you delay, the worse any underlying problems will get. So contact American Air & Heat to check out your AC system whenever you notice anything unusual.
How do I know if my A/C unit is the correct size for my home?
Bigger doesn’t mean better to get the performance and efficiency that count. Having a unit too small will stress the system and provide inadequate comfort. Having a unit that is too big for your home will cause the unit to come on and cool the house rapidly while drawing a lot of power. This quick cycling process draws more energy than would be used under the regular operation of an appropriately sized unit. The system on start-up takes about 5 minutes of operation to achieve full capacity and efficiency. Short cycling also does not allow the system to dehumidify properly.
Before you replace your AC system, make sure your system is sized properly to match your needs and budget. American Air & Plumbing can help. We will thoroughly analyze your home and comfort requirements to determine the proper size and system.
How can I increase the life and efficiency of my home
Here are three tips to help get the most value from your AC:
Clean and replace your filters frequently.
Install window coverings (shades, drapes, shutters or screens) on windows that are exposed to extreme sunlight to help keep room temperatures at moderate levels.
Install a programmable thermostat. Studies show that a programmable thermostat can reduce cooling costs up to 25%.
How can my AC system help to eliminate
Spraying air fresheners or lighting candles only mask odors. They don’t get rid of them because the order source is still there. From decades of experience, we know that bacteria, dust mites, animal dander, cat saliva and mold may be at the root of the problem. One method to sanitize the air is installing germicidal (UV) lights in your home AC system. UV-C helps kill odors and inhibit the growth of biological contaminants, sterilizing surfaces and flowing air in the HVAC system.

According to EPA studies, exposure to air pollutants indoors can be 100 times greater than outdoors. While frequent dusting and vacuuming can help reduce the amount of dust and dust mites, not all airborne contaminants can be eliminated. High quality HEPA filters can help eliminate particles that are too small to be caught by a vacuum. UV-C germicidal light systems are an excellent choice to fight mold, mildew, allergens, bacteria and even viruses in your indoor air. Call American Air & Plumbing to learn about purifying the air in your home. Click here to learn more about high quality HEPA filters from American Air and Plumbing.
Thermostat temperature settings depend on the time of year and your personal comfort preferences. During the summer, the temperature setting on average is 75°-80°. During the winter months, 68°-72° is the average. For homes with programmable thermostats, avoid setting drastic temperature changes. To keep your system from working harder than necessary, do not set a temperature differential of more than 3 to 5 degrees.
How often should I check or replace my
For Florida home systems, we recommend changing filters monthly. During the high-use seasons, it’s better to check more often. If you have a disposable filter, just replace it. Don’t attempt to clean it. Some high efficiency air filters can last up to three months.
What is the proper
indoor humidity level?
The optimum indoor range is 35 to 50% relative humidity, but 40 to 45% is a more realistic goal for most homes. With humidity above this level, you will likely get condensation on the windows which can breed mold. Mold inside homes can lead to allergy and respiratory problems.
professional maintenance necessary?
Like most high value products in your home, you want to preserve your investment. HVAC equipment, especially here in Florida, needs proper care to provide the greatest performance and lifespan. Trained technicians from American Air & Plumbing has Maintenance Programs to help avoid repairs and ensure your system is working at its top level.

Why are my
utility bills so high?
There are many reasons that affect the energy use of your AC system. These include:
Your home is not adequately insulated.
Your system is not properly maintained.
Your filters are dirty and restrictive due to inadequate changing and quality.
Your system is old and less inefficient than newer equipment.
You have an oversized unit.
You have undersized or faulty ductwork.
What fan setting should I use on my
The AUTO setting works best. For central Florida, we don’t recommend constant ON fan operation year-round except during December through March to keep the indoor air better filtered when humidity levels are low.
close off register vents to rooms not in use?
You shouldn’t close more than one register in your home. Closing off or even adding coverings registers will not save you energy because they still will have heat gain from the outside. This heat gain is transferred to the rest of the house through doors, walls, and ceilings causing your AC to work just as hard as if all the registers were open.
What is the difference between Gas Heat and Heat Pump?
A gas heat furnace typically uses natural gas or propane to create a flame that heats metal heat exchanger plates, inside the furnace. Air from the home is then blown over these hot heat exchangers and is then returned as warm air to the house through ducts.
A heat pump does not use gas and is simply an air conditioner running in reverse. To supply warm air, the unit reverses the normal refrigeration cycle and transfers heat from the outdoor air to the inside of the house through the refrigeration inside the system.
SEER is an acronym for Seasonal Energy Efficiency Ratio. It is an energy efficiency rating for air conditioning units. The higher the SEER rating, the more efficient a unit is. For example, older units used to have a SEER rating of 6-10, new units today must have a minimum SEER rating of 13, and the most efficient systems available today are about 19 SEER.
How often should I clean my
For systems in Florida homes, the bare minimum for proper filter maintenance is at least yearly but this may need to increase during the hottest season. If you do not change your filter at regular intervals, your indoor coil could become clogged, which could then cause your condensate drain to clog and flood your mechanical room. American Air & Plumbing performs this cleaning during our maintenance tune-up. Click here to learn more about AC Maintenance from American Air and Plumbing.
How do supply and return duct affect my
air conditioning system?
Undersized ductwork (which is what most homes have) can significantly reduce airflow and can damage the compressor in the outdoor unit. Undersized ducts will also increase noise due to the increased air velocities inside the duct. Undersized ductwork will decrease the volume of air that can be delivered to each room, therefore reducing the comfort of the home.
How often does my system's refrigerant need to be changed?
Variable speed refers to an indoor AC motor that changes speed. This type of motor increases speed and airflow from start-up to full capacity over 8 minutes. This results in a quieter start-up and shut down of the system. This motor is also about five times more efficient than a conventional indoor fan motor.
What does "ton" mean in reference to
Air conditioning units are sized in tons. One ton is equal to 12,000 BTU’s of total capacity. An example: a 4-ton air conditioning unit has a full capacity of 48,000 BTU’s and a 2-ton machine only has a total capacity of 24,000 BTU’s.
