5. Q: How do I know what size air conditioner to get?
A: To exactly size an A/C unit for a specific area requires a heat load calculation which is a bit complicated and is usually made by a licensed HVAC contractor who is experienced and qualified to make these calculations. A quick and easy rule of thumb to use for sizing an air conditioner for a room or house is the square foot method. This formula is used only for a quick approximate and is based on certain guidelines regarding insulation R values, shading, ceiling height, construction materials, windows, doors, purpose of use and occupancy. In layman's terms 1 ton of cooling capacity is equal to 12,000BTU of cooling capacity and 600 square feet of residential living space requires 1 ton of cooling capacity based on adequate insulation, 8' ceiling height and tight windows and doors. To calculate your requirement using this method get the total square footage of living space and divide that number by 600. The answer is the number in tons of air conditioning capacity required. To convert tonnage to BTU's simply multiply by 12,000. This general rule of thumb method can be used for approximate sizing of both central and room air conditioning equipment.

6. Q: Why is my unit icing-up? Why am I getting such little air flow from my registers?
A: There are several things that can cause frost on your coil and/or reduced air flow. First clean or replace you air filter, ensure return register (the largest one in your home) is not blocked or this will cause frost. Basically, anything that restricts the airflow through the inside unit will cause frost. As the frost builds up on the coil, the airflow becomes more and more restricted making the condition worse. When the frost is also on the outside pipes next to the compressor, you have a situation where damage to the compressor can occur. If you see this, turn off the unit and call for service.

7. Q: The system is running but the air is not very cold, what's wrong?
A: If some cooling is taking place but not enough, then the chances are that the system is low on Freon. The only reason a system would need Freon is because the Freon leaked out. If the leak is not sealed before recharging with Freon, the Freon will eventually leak out again. Leak repairs are expensive so if it's a small leak it may be more cost effective to recharge the system every two or three years. Freon recharging is not a do-it-yourself job. As per federal law (EPA), only people certified to handle refrigerant (Freon) are allowed to recharge an air conditioning system.

8. Q: Inside unit is running but the outside unit is not, what's up?
A: Tripped A/C breaker: Check this first. Find the breaker for the air conditioner or Heat Pump (there will be a seperate breaker for the indoor and outdoor units). Turn it completely "off" even if it appears to be "off", then turn it back on again. If it trips again, leave it alone and call for service.

9. Q. How often should we replace the HVAC system filter?
A: There’s no one-size-fits-all answer. The frequency of filter changes is driven by howmuch your HVAC system operates, which is driven by the severity of the seasons.

The best reminder is when you pay your electric bill (monthly). A clogged filter can drastically increase your bill. In some locations (like Central Florida) the cooling system might be in use more than four months of the year – to keep heat and humidity under control. If your house is in such a hot and humid location, you should pay a lot more attention to your filter than in an area where the air conditioning is seldom used. The same logic applies to heating. If the heat is used only on especially cold days during the three or so months of winter, then filters would be checked less often.

Start by checking the HVAC system’s filters at least once a month. Hold the used filter up to the light and compare it to a clean "spare." When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to observed need.

Filtered Air

• Cleaner indoor air can reduce the likelihood that you or your family members will suffer from respiratory ailments, headaches or even nausea.

• Several types of air filters are available to help your home’s air stay cleaner — and keep you healthier.

• Disposable filters are the most common type, and while they are readily available and inexpensive, they are not as effective as other filter types.

• Electrostatic filters actually attract particles to their surface much like a magnet, increasing their efficiency.

• The most effective filters are Carrier Infinity Air Purifiers. They capture and kill even the smallest contaminates to deliver the cleanest possible indoor air.

• Consider your options, choose the filter type that works best in your home, and keep your family breathing easy. And remember, at Freedom Air & Heat, we’re always here to help with your indoor air quality needs.

10. Q: I get funny odors when I run my AC unit
A: Odor complaints are common. There are many different types of odors and different causes:
• Electrical odor
• Damp and musty odor
• Odor problems can be as serious as a gas leak or as simple as a dirty air filter. Unusual odors could indicate a serious problem and should not be ignored.

11. Q: Why are some rooms cooler than others?
A: There are several reason that can cause this including the fundemental laws of nature:
• Hot air rises to upstairs rooms
• Sun sets on the western side of house

My A/C unit seems to work in some rooms better than others. How come?

There are several reasons for this and one is simply the laws of nature.

Now that you’ve settled into your new home, you may have noticed that some rooms will occasionally be hotter or cooler than others. Your upstairs bedroom may take longer to cool in the hot Orlando summer, or the kitchen may be chillier in the winter.

Don’t worry! There may not be anything wrong with your air conditioning system. If your home is multi-level, you will naturally experience the effect of warm air rising to the upper level and cooler air falling to the lower. In addition, solar gain can cause temperatures to rise in certain rooms. This is definitely the case in rooms with west-facing windows during the late afternoon.

But, Brevard weather & forces of nature are not the only factors that will raise your home’s indoor temperature. Cooking and showering will cause the humidity of your home to increase. Even without a raise in temperature, higher levels of humidity can cause you to feel warmer and uncomfortable.

While the laws of nature (and the law of teenagers blow drying hair & taking long showers) may be out of your control, you can use your home’s air conditioning system to improve the situation. By adjusting or closing registers that are too cool in summer or too warm in the winter, you can divert conditioned air to rooms where you need it the most. By making the laws of nature work for you, you should be able to achieve even, comfortable temperatures in every room of your home.

12. Q: What's the difference between Air Conditioners and Heat Pumps?
A: Air conditioners and heat pumps will often look identical in design, foot print, etc. A heat pump can be used instead of an air conditioning unit to keep your home comfortable all year long.

During the summer months, a heat pump draws heat out of your home to cool it. In the winter, it draws heat from outside air into your home to warm it (even though air may be cold in the winter, there is heat in the air).

If you are located in an area where the winter temperature is usually 40 degrees or above (like Central Florida), a heat pump can more efficiently heat your home than an electric furnace.

What's the difference between Air Conditioners & Heat Pumps?

Heat Pump
Air conditioners and heat pumps will often look identical in design, foot print, etc. A heat pump can be used instead of an air conditioning unit to keep your home comfortable all year long.

During the summer months, a heat pump draws heat out of your home to cool it. In the winter, it draws heat from outside air into your home to warm it (even though air may be cold in the winter, there is heat in the air).

If you are located in an area where the winter temperature is usually 40 degrees or above, a heat pump can more efficiently heat your home than an electric furnace.

Air Conditioner
A traditional home comfort system has two parts: an indoor unit, such as a furnace or air handler, and an outdoor unit. An air conditioner is the outdoor unit that rejects heat from your home. Indoor and outdoor units are designed to work together.

When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life. Air conditioning and cooling efficiency is measured using a Seasonal Energy Efficiency Ratio (SEER). A higher SEER means higher energy efficiency. The latest standard for minimum SEER is 13 (beginning January 2006).
