Repair or Replace: Air Conditioner is Blowing Hot Air

Wednesday, October 5th, 2016

When an air conditioner is blowing hot air instead of cool air, it’s not necessarily a sign of a major system failure. In many cases you can repair it yourself, or you may have to call in a professional. Here are a few things to check when your air conditioner is blowing hot air.

Thermostat Settings

Verify that your thermostat is set to cool your home and that the fan is set to “Auto.” When the fan is set to “On,” warmer air may be circulated between cooling cycles.

Breakers

Be sure that the breakers for the system are on — turn them off and then back on if you’re unsure. A tripped breaker can shut down the compressor while still allowing the fan to circulate warm air.

Air Filter

Make sure the air filter is not dirty or clogged. A dirty air filter can reduce airflow, causing the system to shut down and blow warm air.

Outdoor Coil

Make sure that the outdoor condenser coil is not covered or blocked by furniture or other items, and that the coils themselves are not clogged with leaves, grass or small debris. Turn off the power and clean the coils if necessary. A clogged condenser can prevent heat from being properly released.

Indoor Coil

A clogged evaporator coil can cause airflow problems, leading to a frozen coil and the distribution of warm air. If the evaporator coil is accessible, it can be cleaned with a soft brush and a vacuum.

Refrigerant Level

Low refrigerant can also lead to cooling problems. Have a professional check for leaks and proper refrigerant levels.

If these steps have not solved the problem, it may be more serious, such as a major refrigerant leak or a damaged compressor. Have a professional inspect the system and determine the cause. If extensive repairs are required or the air conditioner is over 10 years old, it may be time to replace it.

Air Conditioner Maintenance Tips for Peak Cooling Season

Wednesday, July 20th, 2016

Between the high temperatures and excessive humidity of the Southwest Florida region, peak cooling season can be difficult on air conditioning equipment, leading to inefficient cooling performance or major system malfunctions. With a bit of simple air conditioner maintenance, you can keep your home comfortable, protect your system, and keep your energy costs under control throughout the summer.

Have Your System Professionally Inspected

Before the peak cooling season starts, it’s good practice to have your system inspected by a professional HVAC technician who will perform routine maintenance like checking the refrigerant levels, cleaning the coils, and replacing the air filter. This will ensure that your system runs as efficiently as possible, in addition to helping prevent problems when the system is operating at full capacity later in the summer.

Change the Air Filter Often

A dirty or restrictive air filter can increase your cooling costs, harm your indoor air quality and cause major system problems. During the cooling season, you should check it at least once a month and replace it when required, or at least every two or three months.

Keep the Outdoor Unit Free of Debris

To operate efficiently, the condenser coil of your air conditioner needs plenty of airflow to dissipate the heat from your home. Keep at least a 2-foot area around the outdoor assembly clear of all debris, including furniture, toys and tall plants. If leaves, grass or other debris accumulate in the coils or system fan, turn off the power and remove the large debris by hand; then rinse the coils with a garden hose to remove smaller debris.

Reduce the Cooling Load

Adding extra heat to your home or the air conditioning system can reduce its cooling performance and increase your cooling costs. Keep the outdoor unit shaded during peak cooling season if possible, and use blinds or shades inside your home to prevent solar gain. Avoid heat-generating activities like cooking, washing clothes or bathing during the afternoon.

3 Common Causes of Noisy Air Conditioners

Wednesday, July 13th, 2016

Modern air conditioning systems are relatively quiet, and though some noise is to be expected, any sounds that are new, unusual or that have become louder should be investigated to prevent expensive damage to your system. Three of the most common sources of abnormal sounds include the fan belt, the electrical system, and the compressor, and they should be thoroughly inspected if your air conditioner is noisy or suddenly louder than normal.

Blower Fan Belt

Inside the air handler, especially in a commercial application, a belt connects the blower motor to a squirrel-cage fan, which is used to move air through ducts of your home. Over time, the belt can stretch or begin to crack, and the pulleys on the motor and the fan can lose lubrication or become misaligned. A stretched belt can cause screeching sounds as it slips, and a cracked belt can start thumping as pieces break away. Pulleys that are starved of lubrication or misaligned can begin to whine or screech, as can the blower motor if it’s not properly lubricated. Have the belt adjusted or replaced, if necessary, and check the pulleys and blower motor for proper lubrication and alignment. Failing bearings can also cause this type of noise.

Electrical System

Faulty electrical contacts, relays, and capacitors can cause many strange noises in a system, including clicking as relays or contacts fail to engage properly or buzzing as the start capacitor fails to start the compressor properly. Have the electrical system inspected, cleaning any dirty contacts and replacing burned or faulty components.

Compressor

Problems with the compressor can cause screeching, whining, thumping, buzzing or hissing noises. If it’s hissing, there’s likely a refrigerant leak; and if it’s buzzing, the start capacitor may have failed. Screeching, whining, thumping or other noises may indicate serious problems with the compressor, such as damaged pistons or scrolls, lubrication failure or worn brushes. Have the compressor inspected immediately to avoid unnecessary damage.

If your air conditioner is noisy, talk to our HVAC experts at Conditioned Air today to determine the cause of the problem. We serve the Southwest Florida area, including the communities of Naples and Sarasota.

Summer Air Conditioner Maintenance: It’s Not Too Soon

Wednesday, May 11th, 2016

Summer may seem like it’s a long time away, but it’s never too early to think about summer air conditioner maintenance. By scheduling your summer air conditioner maintenance visit now, you can make sure that your system is completely ready for the hot and humid weather of Southwest Florida. You’ll also avoid your HVAC contractor’s busy season which is often during the early summer when people discover that their air conditioners are not working as expected.

Why Routine Maintenance is Critical

Routine maintenance extends the life of your air conditioning system by eliminating unnecessary causes of major system problems, such as a compressor that overheats and fails due to dust accumulation on the evaporator coil. By performing regular maintenance and correcting small problems that could cause major failures, you not only extend the life of the system, you also ensure that it continues to run efficiently, reducing energy usage, lowering your utility bills and protecting your system’s remaining manufacturer warranty.

What is Done During the Maintenance Visit

The HVAC technician will inspect your system thoroughly, checking for problems such as dirty coils, refrigeration leaks and electrical problems. The technician will then perform routine maintenance, which typically includes cleaning the condenser and evaporator coils, checking refrigerant levels, cleaning the blower fan, adjusting the blower motor belt, lubricating the blower motor and pulleys, changing the air filter and inspecting the electrical system. If any problems are found, the technician will recommend possible solutions and perform any repairs that you have agreed to.

What You Can Do Between Visits

There are also several things that you can do between service visits to keep your system running properly. This includes checking your air filter regularly—about once a month—and replacing it when it becomes dirty. You should also keep the supply and return vents free of obstructions, such as furniture or curtains, and keep the area around the condenser coil clean and free of debris.

Troubleshooting Hot and Cold Spots in Your Home

Wednesday, January 20th, 2016

Uneven temperatures in your Southwest Florida home are not only uncomfortable, but they may also indicate a problem with your HVAC system or the house itself. By troubleshooting hot and cold spots in your home, you can find the source of the problem and take steps to correct it.

Malfunctioning HVAC System

An improperly-sized or malfunctioning HVAC system can easily lead to hot or cold spots in your home. Make sure the air filter is not clogged or excessively dirty, and replace it if necessary. The air filter should last several months, but it is a good idea to check it at least once a month. Inspect both the indoor and outdoor coils of a heat pump or air conditioner. If the coils are dirty or clogged with debris, the system will not heat or cool properly, and they will need to be cleaned. If you have a furnace, make sure that the burners are free of dirt and soot to keep it heating efficiently. If the problems remain, have a professional inspect the system and make sure that it is sized properly.

Duct Problems

Blocked or leaking ducts can also cause uneven temperatures. Make sure all the vents are open, and check inside the ducts for obstructions and remove them, if possible. Inspect the outside of accessible ducts for cracks, holes, disconnected joints and missing or damaged insulation. If the ducts are leaking, missing insulation, excessively dirty or obstructed, have a professional repair them.

Drafts or Air Leaks

Hot or cold spots can be caused by air leaking into or out of your home. Seal drafty windows, doors, and any holes in the exterior walls with weatherstripping, caulk or expanding foam insulation, and make sure that your home is properly insulated.

Thermostat Problems

Make sure that your thermostat is working correctly, and replace it if necessary. Also, make sure that it is in a suitable location to get a correct reading, and not in a drafty or sunny spot.

DIY Repairs: Avoid Voiding an HVAC Warranty

Wednesday, December 23rd, 2015

A new HVAC system usually represents an investment of several hundred dollars or more. In most cases, new HVAC equipment will be covered by a manufacturer’s warranty that protects you against certain types of defects or problems. Warranties can be voided, however, if you don’t follow appropriate procedures. One of the most common ways of voiding an HVAC warranty occurs if you try to repair the system yourself. If your cooling system is still under warranty, it’s best to avoid DIY repairs and leave these matters to an HVAC professional.

Maintaining Valid Warranties

To ensure the warranty remains valid and that the manufacturer will honor the warranty, you must ensure that repairs and preventive maintenance are performed by HVAC professionals. It may be tempting to try to avoid a repair bill by trying to fix problems yourself, but unless you are a qualified HVAC expert, leave the repairs to the pros. In some cases, the HVAC pro you use may even need to be trained and certified by the company that made your HVAC equipment.

By relying on an HVAC professional, you can be sure that the work is performed properly, that the system will work correctly when the repairs are complete, and that the system will be safe to use. Manufacturers will be assured that proper procedures have been followed during the repair, that authorized parts have been installed, and that other problems haven’t been introduced into the system during the repair procedure.

Maintenance You Can Do

While significant HVAC repairs require the services of a licensed professional, there are some minor maintenance tasks you can perform that will leave your warranty intact. These include:

  • Changing air filters.
  • Cleaning the interior and exterior of the cabinet.
  • Clearing grass and other vegetation from outside of the unit.

Air Conditioner Freezing Up? This Could Be Why

Wednesday, October 28th, 2015

One of the most common air conditioning problems in South Florida is a frozen evaporator coil, which happens when the evaporator coil cannot absorb heat correctly and its temperature drops below freezing, turning any condensed moisture on the coil into ice. Not only does this prevent the system from cooling properly, it can also cause permanent damage to certain components. To get the system running properly, you will have to determine the cause, correct it and thaw the coil.

Airflow Problems

In many cases, poor airflow can prevent the coil from absorbing the heat in your home, allowing it to freeze up. Reductions in airflow can be triggered by a dirty or clogged air filter, an obstructed supply or return duct, or problems with the blower fan. Replace the air filter, if necessary, and check your air ducts for obstructions. Make sure none of the vents are covered by furniture, curtains or other items. Check the blower fan and make sure that it is relatively clean and operating correctly, and that its belt is not damaged or slipping.

Dirty Evaporator Coil

Household dust, pet hair and other debris can accumulate on the evaporator coil over time and prevent it from absorbing heat properly. If your evaporator coil is excessively dirty, allow it to thaw, then clean it gently using a soft brush and a vacuum cleaner, being careful to not bend any of the delicate cooling fins.

Refrigerant Problems

Low refrigerant levels, leaks or a clog in the lines can also cause major air conditioning problems like freezing. To correct a refrigerant problem, or any other serious issue, you will need to call a professional.

Thawing the Coils

To thaw the evaporator coils, turn off power to the system and allow the ice to melt naturally. To speed things up a hair dryer or heat gun can be used in a pinch, but never use tools to remove ice, as they may damage the refrigerant lines.

Quick Guide for Troubleshooting Your AC Unit

Wednesday, October 21st, 2015

An air conditioner that isn’t working properly can be a cause for concern, but it shouldn’t make you panic. Sometimes a few simple troubleshooting steps can let you resolve the problem and get the system working again without the need to call for repair. Here are a few things to look for when troubleshooting air conditioner problems and A/C noises.

A/C Doesn’t Work

  • Check the power supply to the air conditioner and make sure it is plugged in and receiving power.
  • See if the circuit breaker controlling the A/C has tripped. Reset the breaker and see if the air conditioner comes on. If the A/C unit keeps tripping the breaker, there may be an electrical problem that needs to be fixed.
  • Make sure all vents and registers are open and free of blockages from furniture, boxes, clothing, or other objects that could restrict airflow.
  • Make sure the thermostat is working and that the temperature and operational settings are appropriate for the season. Change the batteries in the thermostat if necessary.

A/C Noises

  • Rattling or clattering noises coming from your air conditioner could be the result of an access panel or other cover being loose.
  • If you detect new or unusual A/C noises, give the system a short period of time to operate and see if the noises continue.

A/C Produces No Cool Air

  • If the fan is working, make sure that the system hasn’t been set to fan-only operation. Set the system to “cool” if necessary.
  • Listen to make sure the compressor is working and that coolant is being circulated through the system.
  • Check the HVAC system ductwork to ensure that there are not damaged or missing sections and that all sections are fitted tightly together. Each connection should also be sealed with mastic, a specialized sealant, or with metal tape.

Conditioned Air helps the residents of Ft. Myers, Sarasota, Naples, Bradenton, and the surrounding Florida communities keep their air conditioners working properly and reliably.

Best Practices for Air Conditioner Maintenance

Tuesday, September 15th, 2015

The air conditioner in your home or business means more to you than comfort on hot Florida days. It also represents an investment of hundreds, perhaps thousands of dollars in equipment that should give you years of reliable service. The best way to ensure your cooling system works at its best for as long as possible is through regular preventive maintenance. Here are some useful best practices for air conditioner maintenance and some reasons why you should consider a maintenance service agreement.

  • Check the filters: The filters in your air conditioner help clean the air moving through your cooling system and into your indoor spaces. They also contribute to the airflow needed to ensure the equipment operates properly. Dirty, clogged air filters are a major contributor to cooling system malfunctions and breakdowns. Check these filters at least once a month and change them when they get dirty.
  • Ensure proper airflow: The conditions surrounding the outside unit of your air conditioning system also affect system airflow. Make sure that grass, weeds, hedges, tree limbs, and other vegetation is trimmed away from the outside unit to provide plenty of clearance for proper airflow. Remove mud, dirt, leaves, sticks, and other material from the cabinet vents.
  • Hire a professional: Almost anyone can change an air conditioner filter, but when it comes to the more complex technical elements of preventive maintenance, always hire a professional HVAC technician. Your HVAC expert will be able to evaluate the performance and condition of your cooling system and make necessary adjustments and minor repairs that will improve performance and extend the equipment’s lifespan.
  • Purchase a maintenance service agreement: Sometimes called a service contract, a maintenance service agreement provides for an agreed-upon schedule of maintenance services from your HVAC service provider. Your HVAC company will schedule maintenance visits for you. Many service agreements also provide benefits such as discounts and expedited service.

Conditioned Air serves residential and commercial air conditioning customers in Ft. Myers, Naples, Bradenton, and Sarasota. Contact us today for more information on air conditioner maintenance and to find out more about our maintenance service agreement plans.
