Common A/C Problems Florida Homeowners Might FaceDuring the heat of the South Florida summer, the last thing you want is for your home air conditioner to stop working.

Before Investing in HVAC Upgrades, Do the Load CalculationsBefore you upgrade your HVAC system, it’s vital that your contractor does the proper load calculations first, so you purchase cooling or heating equipment that’s matched to your particular home. Professional heating and cooling specialists must do the math on your behalf for the very best installation.

The U.S. Department of Energy stresses that ducts and HVAC systems should conform to Manuals J and D for economy and efficiency. These are load calculation protocols developed by the Air Conditioning Contractors of America that heat gain and loss in your residence or business, as well as duct design and size. The results are translated by computer software so your structure is properly cooled (or heated) and so you don’t buy oversized or undersized equipment. Manual calculations are a thing of the past and are frequently wrong. Both Manuals J and D formulate the appropriate load calculations and ductwork compatibility to create a comfortable and energy-saving climate in your home:

  • Manual J measures every room in your house, calculating the heat gain under the most severe heat and humidity. Your contractor cannot provide you with the properly sized equipment without these numbers. An A/C unit that’s too big wastes energy and your money; one that’s too small can’t handle the load and will compromise your level of comfort.
  • Manual J provides calculations that take into consideration our Florida climate. Its tables let your contractor measure your installed insulation, window-glass area and orientation, the energy load from your large appliances, and the air-leakage rate of your building. It even considers the number of people in your family and the energy demand of your lighting. These numbers – along with the cubic footage of your home and its number of levels – will determine the correct size of your A/C or heat pump installation.
  • Manual D gauges the design and size of your duct system, including the diameter of your ducts, how many returns and registers you require, and how to configure the duct runs and how they enter your A/C equipment and your rooms. These results are directly based on those from Manual J. If your ductwork isn’t right, it will compromise the efficiency and performance of your HVAC upgrade.

Your New Air Conditioner: These 4 Factors Can Make or Break a High SEER RatingThis time of year, when temperatures are beginning to climb in South Florida, is the perfect time to invest in a new central air conditioner or your home. If it's been a while since you've been in the market for one, you might be surprised at the high efficiency ratings (SEER – Seasonal Energy Efficiency Ratio) of the latest generation of A/Cs. If you want to make sure that your new system will operate as efficiently as its SEER rating, though, it's important that four factors are handled correctly during installation and operation. Otherwise, you may get SEER 10 performance from a SEER 16 air conditioner.

  • Airflow – If you expect your new air conditioner to reach its peak performance level, proper airflow is essential. Without it, your unit's SEER rating will drop. This is typically caused by too-small ducts, restrictive duct layout, restrictive or improper grilles, a mismatched air handler, or a malfunction in the blower motor or fan.
  • Charge – Many homeowners take the importance of their refrigerant charge for granted. However, if your A/C doesn't have enough refrigerant, its efficiency will drop, it won't cool your home as well as it should, and eventually, it will break down. A qualified HVAC technician will check the refrigerant charge, and if it's low, add refrigerant and check for leaks.
  • Ducts – If your home's air ducts aren't tightly connected and sealed, your air distribution system will leak conditioned air before it reaches its destination. This can cause a drop in performance that has been rated as high as 35 percent in field studies, which will clearly add to your home's overall energy usage. Plus, leaks in your return ducts can allow unfiltered air to infiltrate your ducts and indoor air.
  • Size – This can be a tricky matter. Many home HVAC systems are either undersized or oversized, and either issue will result in efficiency and performance problems. In order to make sure that you size your new air conditioner properly, elicit a professional opinion. The technician will conduct a load calculation on your home to determine the size A/C that will deliver optimum cooling.

Your Split Air-Conditioning System: Why the Right Match MattersA split air-conditioning system employs two parts working together – the indoor evaporator/air handling unit and the outdoor condensing unit, which also contains the compressor. These components work as a team to provide optimal comfort and energy efficiency for your home.

How do you think I can find the best Air Condition Company in Lake Worth

When you complete what you can and have an HVAC professional perform the technical maintenance, you reduce both your electric bill and the odds of an air conditioner breakdown. Grass clippings and dead leaves can slow the flow of air through the compressor, making it work hard. In either case, call a professional. If it still doesn’t work, you may have a problem with your wiring or with your compressor, both of which require a call to your HVAC technician. Give us a call to schedule your springtime air conditioner maintenance, assuring you of a cool and comfortable summer. If not, check to see if the circuit breaker is tripped. For more tips on raising your indoor air quality with an efficient A/C filter, as well as general home comfort advice, contact the experts at Robert McGill Air Conditioning. Uses pressure gauges to measure the airflow going through the air handler and inspects the ducts for leakage. When your A/C breaks down in the middle of the Florida heat, it can be a nightmare. If you haven’t had it serviced yet this summer, it’s not too late to improve A/C performance. It’s also a good time to clean up your air conditioner and get it ready for the months of really heavy usage ahead. Arrestance and dust spot efficiency: These refer to an air filter’s ability to capture and remove dust particles from the air, respectively. They are typically measured in a lab, under controlled test conditions, using only larger particles. This makes them a poor way to measure efficient A/C filter performance under real world conditions, which deals with much smaller-sized particles. Remove any debris or vegetation near the outside unit, and make sure there’s at least two feet of clearance all the way around.
