Warning Signs: A/C Freeze in Summer

Warning Signs: A/C Freeze in SummerAs strange as it might sound, it’s possible for air conditioning systems to freeze up during summer. Even with the high summer temperatures in the Peachtree City area, you can end up with A/C freeze that stops your system from being able to work properly. Find out more about why this happens and what you should do about it.

Signs of a Frozen A/C

Your A/C system might be frozen if you notice that there is water leaking out of your air conditioner. You might also see water pooling below it if you have A/C freeze. Another sign of a frozen air conditioner is having warm air flowing from the registers while your HVAC system is running. If you have any of these signs, it’s important to have a professional HVAC technician inspect it and make repairs.

Causes of a Frozen Air Conditioner

How can an air conditioner freeze in the middle of summer? This can happen when the evaporator coil that’s part of your HVAC system becomes frozen. The evaporator coil can freeze if your system is leaking refrigerant or if something is blocking air from flowing through it. Professional HVAC technicians can repair a refrigerant leak or determine the cause of an airflow blockage.

What to Do About a Frozen Air Conditioner

You should have your HVAC system professionally repaired if it’s frozen. This helps ensure that repairs are done correctly, so that you don’t encounter similar problems or accidentally cause more damage.

Preventing A/C Freeze

A common cause of frozen air conditioners is dirty air filters or cooling fins, which prevent air from flowing freely. Changing your air filter each month or every other month helps prevent this from occurring. Set a reminder, so you’ll do this regularly. Scheduling routine HVAC maintenance helps lower the risk of having the cooling fins become dirty enough to block airflow.

If you’re dealing with A/C freeze in summer, contact Powers Heating and Air for help. Our technicians in Peachtree City can repair your HVAC system, so you can have dependable cooling all summer long.

Are HVAC and A/C Synonymous? 

Are HVAC and A/C Synonymous? When it comes to HVAC terms, you’ve probably heard some used interchangeably, so it may seem that they’re synonymous. Two such terms are “HVAC” and “A/C,” and learning their exact meanings can help you better understand the particular equipment in your home comfort system, and how you can keep everything operating reliably and efficiently with regular preventive care.

What HVAC Means

The term “HVAC” is an acronym for heating, ventilation and air conditioning, and it’s usually used to describe the entire comfort system in a home. Depending on your home and needs, your heating and air conditioning equipment might include a gas-fired furnace, electrically-powered split-system air conditioner or heat pump, a mini-split, or a geothermal heat pump. The ventilation portion of the system typically refers to the air circulation components including the blower unit, air filter, and ducting, but it might also cover a whole-house ventilator, or add-on air purification or filtration unit.

A/C Definition

A/C most often means “air conditioning,” but it can also refer to any of the different types of household cooling equipment, including central split system heat pumps and air conditioners, ductless mini units, geothermal systems, and window units.

Preventive Maintenance for Your Equipment

To keep your comfort system operating at peak performance, all the shared components should have a semi-annual inspection, cleaning and tuneup by a trained and experienced HVAC technician.

 

Here’s a general overview of some of the key maintenance steps taken for specific portions of an HVAC system:

  • Cooling: For optimal comfort and efficiency, a technician should perform spring maintenance that includes verifying the refrigerant level, cleaning the condenser and evaporator coils, and flushing the condensate drain.
  • Heating: In the fall, heating equipment service should include inspecting the exhaust/vent system, testing/cleaning the gas burner and assessing the heat exchanger.
  • Ventilation: To ensure that the air distribution components are working properly, the blower assembly should be cleaned and lubricated, the ductwork inspected, and a new air filter installed.

What Elements are Essential for HVAC Design?

What Elements are Essential for HVAC Design?Having modern, energy-efficient heating and cooling equipment is important if you hope to have a comfortable home that’s doesn’t cost a fortune to condition. However, another crucial ingredient in a modern household is proper HVAC design.

 

Following are some key characteristics of good residential HVAC design:

A correctly sized cooling or heating system

Your contractor should insist upon conducting a heating or cooling load calculation (depending on the system) that takes into account your home’s size and layout, energy efficiency, window coverage, orientation on the lot, and much more. With that information in hand, your contractor will recommend the right size A/C, heat pump or furnace for your particular home. This way, you’ll avoid an under- or over-sized HVAC system, each of which has its own set of potential problems affecting energy costs and comfort.

Effective ventilation

You don’t want a home in which the same, stale air circulates again and again. This is neither comfortable nor healthy. Consider installing a Heat Recovery or Energy Recovery Ventilation system, which constantly exchanges stale air for fresh air, and at the same time transfers heat energy (and moisture in an ERV) between parallel air streams for added efficiency and comfort.

Air distribution system

An efficient air distribution system, in which the duct network and vents and registers are designed for optimum airflow and comfort. Each room should have “supply” and “return” registers or grilles connected to ductwork, where practical.

Effective humidity control and air cleaning

Ideal HVAC design often comes with whole-house dehumidification and sometimes humidification as well, depending on the climate. Whole-house air-cleaning systems are also desirable, especially in homes with particular air-quality concerns.

Temperature control that works

our best bet is a modern, Wi-Fi thermostat that will allow you to program energy-saving setbacks to save energy and money when you’re at work all day or at night in the winter, and adjust or set programs remotely with your smart-phone, tablet or laptop.

Reasons Why Your Peachtree City A/C Is Blowing Hot Air

Reasons Why Your Peachtree City A/C Is Blowing Hot AirWhen you turn on the A/C in your Peachtree City home, the last thing you want is hot air blowing from the vents. Air conditioners are complex machines, and there could be many reasons why your A/C is blowing hot air. Just like your car, they need regular service and maintenance like changing the filters and checking the drain lines.  If you want to try troubleshooting the issue before calling your HVAC contractor, here are a few places to start.

Thermostat Settings

The first step in trying to determine why your A/C is blowing hot air is to check the thermostat mode. The thermostat should be in “cool” or “auto” mode, with the temperature set below the current temperature reading.  If the unit doesn’t start blowing cooler air with the lower temperature setting you need to call an expert for service.

Iced Evaporator Coil

A common problem with A/C systems is ice accumulation on the evaporator coil. This is located at the furnace or heating component in the house.  If there’s more than a thin layer of ice or frost, or if the insulated refrigerant line coming out of the evaporator coil is frosting or icing, the refrigerant is having a tough time extracting heat from your home. Ice accumulation is often caused by a lack of airflow. Check the air filter and if it’s dirty, change it. Allow the ice to melt. If the ice accumulation returns with a clean filter, there’s a more serious problem that requires professional service.

Refrigerant Leak

Air conditioners cool homes by using very cold refrigerant to extract heat. The refrigerant is pumped between the indoor evaporator coil and the outdoor condenser coil. Low refrigerant can be a cause for the system blowing hot air, and it’s also a contributor to ice accumulation on the evaporator. Refrigerant is pumped through a closed-loop system. If refrigerant is low, there’s a leak that needs to be repaired or the faulty component replaced.  Leaving a refrigerant leak too long without being repaired can lead to additional component failures including compressor failure.

Compressor Problems

The compressor pumps refrigerant between the evaporator and condenser coils. The compressor also prepares refrigerant to release heat at the condenser coil by squeezing it. If there’s a problem with compressor function, your A/C system may still run, but it won’t cool your home. Common indicators of compressor problems are a lack of preventive maintenance and unusual noises, such as loud hissing, screaming, rattling or humming.  If you suspect a compressor failure turn the unit off and call for an HVAC professional immediately.

If your A/C is blowing hot air into your Peachtree City home and you need a professional solution, call the experts at Powers Heating & Air today.  We also service all of Fayette and Coweta Counties including Sharpsburg, Fayetteville, Senoia, Tyrone, Newnan and Brooks.

Ways to Protect Your A/C Unit from Theft

Ways to Protect Your A/C Unit from TheftYour cooling system is not only an investment in your comfort, but a major financial one as well. Opportunistic thieves have begun targeting commercial and residential air conditioners, which are relatively easy to steal and can yield a few hundred dollars in easy money. Unfortunately, the cost of replacement can run you in the thousands, so protecting your A/C unit from theft should be a priority.

Why Steal an A/C? 

With unemployment and copper prices on the rise, A/C units have become a hot commodity. It takes less than five minutes to remove your outdoor condensing unit with little more than a pair of bolt cutters. While thieves used to take the time to break open the unit and steal what they needed, it’s now common practice to remove the entire component. It’s often out of sight for aesthetic purposes, making it even easier for thieves to work undetected.

Protecting Your A/C Unit From Theft

While no security system is completely foolproof, there are steps you can take to make thieves think twice about targeting your equipment. Following are a few recommendations:

  • Anchor the unit – The condensing unit of your A/C is already heavy, but you can make it even heavier if you anchor it to a solid cement base. Talk to your contractor to see if they  can provide a poured concrete pad and then set your a/c unit on the pad using at least 1/2″ anchor bolts.
  • Install cameras – Security cameras, whether real or fake, may be a deterrent to some thieves.
  • Add a cage – Build a steel cage around the air conditioning unit or contact your local HVAC company to see if they can build one for you.  The cage needs to be secured to a concrete pad or concrete footings below grade. The cage should have a lock and be sturdy and large enough for your contractor to remove the cover for maintenance or repairs.
  • Install an alarm – Install an A/C alarm.  Your local a/c contractor can recommend an alarm system that will alert you in the event of a refrigerant leak, if the line is cut, or if power is lost.

For more tips on protecting your A/C unit from theft, call the experts at Powers Heating & Air. For over 35 years, we’ve been providing quality service to homeowners in Peachtree City, Fayetteville, Newnan, Sharpsburg and the surrounding areas.
