Looking for Your A/C Tonnage

Looking for Your A/C TonnageThe A/C tonnage figure refers to the amount of cooling your air conditioner can supply to maintain optimum comfort. When you hear HVAC contractors or others referring to the sizing of an air conditioner, they’re not talking about its physical dimensions in feet and inches. They’re referring to its BTU tonnage—the actual volume of cooling it’s designed to generate under controlled conditions.

Why Tonnage Matters

It’s useful to know the tonnage specification for your air conditioner if you’re about to start shopping for a replacement. It helps you comparison shop among different makes and models of a similar specification.

However, the tonnage of your present unit should never be the only factor in choosing an adequate replacement. Conditions and cooling requirements in a home change over the years. Therefore, the tonnage of an older, existing air conditioner may not be right for your house today.

Because both over-sized and under-sized A/C units tend to run far less efficiently and cool less effectively, a formal cooling load calculation should be performed by a qualified HVAC professional to accurately determine the A/C tonnage currently required in your home for optimum energy-efficiency and cooling performance.

Finding The Tonnage Spec

To locate the tonnage of your existing air conditioner, look at the manufacturer’s data plate, usually affixed to the side of the A/C outdoor condenser unit. The Model Number listed on the plate will usually be a string of numbers and letter, separated into sections. Look for a section that begins with “0” followed by a two-digit even number between 18 and 60. Divide that two digit number by 12—which stands for 12,000 BTUs, a “ton” of cooling—to determine the tonnage. For example, if the section in the Model Number reads 048, dividing 48 by 12 produces 4. This means your air conditioner was a 4-ton unit at the time it was manufactured.

Smart Thermostats: 5 Reason to Love Them

Smart Thermostats: 5 Reason to Love ThemHave you ever considered installing a smart thermostat in your home? Perhaps you’ve thought it sounded too complicated and you were wary of adding more technology to your life. The fact is, smart thermostats offer the homeowner so many benefits, it’s worthwhile just to take a look at them and consider the benefits carefully.

Energy Savings

We’re a big fan of programming HVAC system schedules that cut back on energy use when you’re sleeping or away from home. Government research has shown homeowners can easily save 10 percent on energy bills by setting the thermostat back 7-10 degrees eight hours a day. A smart thermostat makes it so much easier to set these schedules than a programmable thermostat. Just go into the app on your smart device, and set the temperature the way you want it.

Convenience

Whether you’re a block or a world away, you can set your thermostat as needed. Say you’re on vacation and you see that a cold front is bearing down on the Peachtree City area. You need to raise the thermostat to prevent the pipes from freezing and to ensure the pets are comfy. If you can get a signal on your phone, you can reset the thermostat to whatever temperature you desire.

Or, say you’re headed home and you’d like to turn the thermostat down a bit to cool the house off in the summertime. Install a smart thermostat with sensors that communicate when you’re within a certain range so the air conditioner turns on in anticipation of your homecoming.

Track Energy Use

Your smart thermostat can help you keep track of your energy use. This allows you to compare use with previous years so, when your bill goes up, you can try to pinpoint the reason. Maybe your home has air or duct leaks, or maybe the thermostat is malfunctioning. The smart thermostat can keep you on top of things.

Heat Pumps 101: Air Source vs. Ground Source

Heat Pumps 101: Air Source vs. Ground SourceUsing a furnace to heat your home in winter can keep it cozy, but it can also lead to higher utility bills. Heat pumps provide a way to warm up homes at a lower cost. Should you go with an air-source heat pump or a ground-source one for your Peachtree City home?

Learn more about the differences between these heating systems.

Heat Source

Air-source heat pumps pull heat from the air outside your home and bring it indoors. Ground-source heat pumps take heat from the ground and move it inside your home. Both heat sources are renewable forms of energy, making them cleaner and more environmentally friendly than natural gas and other fossil fuels. Keep in mind that you might need to rely on electrical strips or a similar secondary heat source if your air-source heat pump isn’t able to warm your home, which can happen during periods of extreme cold.

Heating and Cooling

Air-source and ground-source heat pumps are both able to heat homes in winter and cool them off in summer. This means you don’t need to run and maintain a separate air conditioning system. A heat pump takes hot air from your home and moves it either outside or into the ground.

Heat Pump Installation

Air-source heat pumps tend to be easier to have installed compared to ground-source ones. You can have your air-source heat pump set up outside your home just as you would have a central air conditioning unit installed. Ground-source pumps require a more complicated installation process. These systems have pipes that need to be installed in the ground, which involves excavating part of your yard.

Heat Pump Costs

A ground-source heat pump typically costs more than an air-source heat pump due to the installation process. Both types of heating systems can save you money in the long run thanks to reduced energy bills and more efficient heating compared to gas and electric furnaces.

If you’re trying to decide between an air-source heat pump or a ground-source one for your Peachtree City home, please contact Powers Heating and Air.

Tips for Warming Up Cold Floors

Tips for Warming Up Cold FloorsNothing can remind you of winter faster than cold floors. If you’re one of those who doesn’t enjoy chilly feet, rest easy. There are many ways to keep your feet warm for the duration of the winter.

Air sealing

Looking around your home for air leaks and sealing them will help your feet stay warmer and cut your heating bills as well. Explore your home for leaks around the baseboards and exterior doors. Leaks around the windows may also be common, as well as electric and cable outlets that sit on the exterior walls. Caulk, weatherstripping and expanding foam will seal most leaks.

Duct boosters

If the places where you spend most of your time seem cold most of the time, ask a pro from Powers Heating & Air to find out why. There may not be enough air coming from the furnace to warm those rooms or there’s too much going elsewhere. HVAC professionals can balance the airflow to increase overall home comfort and prevent cold floors.

Portable heaters

A small space heater might be what you need under your desk or blowing on your cold feet to take off the chill. If you use any kind of portable heater, use it safely by following the manufacturer’s instructions carefully.

Rugs

Rugs add a layer of insulation that will insulate a cold floor in proportion to its size. If your home has a crawl space or a basement, consider hiring a contractor to add more insulation to the space between the first floor and the basement ceiling.

Radiant floor heating

While our winters aren’t as cold as those up north, there’s still a case to be made for radiant floor heating in this location. Winters can be cold and radiant heating is known for its even heating and comfort that starts at the floor. People with allergies or asthma fare better with radiant heat since it doesn’t blow air throughout the house.

Ensuring Boiler Safety

Ensuring Boiler SafetyIf you’ve recently purchased a home that has a boiler, you may not be familiar with this kind of heating system. Boilers heat water using gas or electricity, then pump the hot water through piping to radiators in each room, or circulate it through tubing installed under the floors. For the well-being of your family, you should ensure boiler safety by following these steps:

Have the Heating System Maintained Annually

A boiler is just like a gas furnace or heat pump in one regard – it needs regular preventive care from a qualified HVAC pro to operate safely. When you schedule an annual system inspection, cleaning and tuneup, a technician will complete a number of safety-centric tasks, including:

  • Verifying correct water pressure, temperature and flow.
  • Checking the water level and testing the low-water fuel cut-off.
  • Inspecting the pressure tank and testing the pressure relief valve.
  • Verifying proper pump, zone valve, and damper operation.
  • Checking for corrosion and cracks in the heat exchanger.
  • Inspecting and cleaning the burner.
  • Cleaning the pilot assembly and orifice, and inspecting the flame sensor.
  • Checking for leaks and the condition of the seals.
  • Lubricating all the system motors.
  • Inspecting the venting system.
  • Checking the wiring and electrical connections.
  • Testing key safety features including the high limit control.

Stay Vigilant About Developing Issues

In between professional maintenance visits, it’s important to stay vigilant for newly-developing problems with your boiler, and call your HVAC contractor for help if you have concerns. Signs of potential safety issues with a boiler include water leaks or puddles near any of the system components, alarming or odd new noises coming from the equipment, and a distinctive sulfur-like or rotten-egg smell that warns you of a gas leak.

Install and Maintain CO Detectors

If you have a gas-fired boiler, deadly carbon monoxide (CO) can be produced if it’s not combusting fuel properly. To warn you about the presence of this life-threatening gas, you need to have CO detectors installed throughout your home, then test them monthly and replace their batteries regularly.
