Central Air Conditioners vs Wall Units

With ever-climbing summer temperatures and extreme weather patterns causing homeowners nationwide to suffer and sweat, air conditioning is rapidly moving up on the priority list of many homeowners. Should you go whole hog for a central air conditioner, or limp by with a wall/window unit?

Bargain or Bust?

The seemingly low prices of wall units can make them tempting to purchase. However, they’re often not what homeowners bargain for…

Energy Efficiency

If you’re looking for the most bang for your cooling buck, consider central air conditioner installation. Wall units are engineered for cooling only small spaces, providing less cooling capacity. Central air conditioners use less energy overall, especially compared to a gaggle of wall/window units running (noisily) in tandem. Though wall units may seem cheaper, if you need more than one to stay comfortable in the summer heat, the more cost-effective solution is central air conditioning.

Value

If you sell your home, central air conditioners hold more value, whereas wall units, especially those poorly installed, can detract.

Comfort

For consistency in temperature, central systems offer superior comfort, hands-down. Integrated with a smart programmable thermostat, simply set it and forget it, cooling your entire home. To achieve the same feat with multiple wall units would be impossible, as room size affects temperature consistency, requiring frequent thermostat adjustments at each unit to avoid hot and cold spots.

Air Quality

Central HVAC systems do a far better job of filtering allergens and pollutants from the air than wall units, especially when paired with HEPA home air filters. For those with asthma and allergies, a central system is a wiser investment.

Humidity

Central air conditioners remove more humidity from the air than wall/window units, helping you feel more comfortable without the need to crank the thermostat to a lower temperature setting.

Versatility

With heat pump installation and some ductless systems, adding a heat source is also possible. Due to their size, very few wall units provide reliable heat.

No Room For Duct Work?

If your smaller or older home lacks sufficient space for ductwork, you still have options. A relative newcomer to the American market, ductless mini split installation offers interior design flexibility and some of the highest SEER ratings and efficiency levels on the market. Compact and easy to install, they require no ducts, as their name implies. A few small, 3-inch holes for coolant lines are all that is needed to connect interior air handlers to exterior components. Located high on the wall, suspended or mounted flush into the ceiling, and operable via remote, ductless mini split systems offer some of the lowest operating costs and highest performance of cooling systems among the market today.

What Causes Condensation on Air Conditioners? | eHow

Does your air conditioner look like it’s feeling the heat, sweating alongside you in the stifling summer weather? Condensation coming from cooling units is common in the summer months. What’s causing it, and is it good or bad for your system? The pros at H&H Heating & Cooling have the answers to all of your condensation questions.

What Causes Condensation on Air Conditioners?

The same process that causes a cold glass of iced tea to form water droplets on its exterior in the summer causes condensation on your air conditioner. As your system’s evaporator coil cools warm air that passes over it, absorbing heat and moisture from the air, condensation forms. As this condensation drips down, it collects in your system’s drain pan and (if it’s properly maintained and not clogged) through the condensate drain line and out of your home.

Can Condensation Hurt My AC System?

Condensation is normal for properly running air conditioning systems. Excess condensation, like sweating ducts and drips from outside the unit cabinet indicates a problem with your unit and points to an HVAC system issue that requires emergency HVAC repair service. Without prompt attention, excess condensation could overwhelm your air conditioner’s drainage system, causing damage within your home. This damage can range from high humidity levels that lead to mold and mildew proliferation and spots, to structural damage from drainage water that accumulates and puddles.

What HVAC System Issues Result In Condensation?

• Condensation Pan problems
  Your A/C unit condensation pan collects condensate water from the evapaorator and sends it to an external drain however overtime condensate pans can crack which can lead to water running through the unit and spilling out causing damage to the unit and to the home.
• Clogged or Dislodged Drain Line
  If bacteria and fungus buildup in the drain line, it can become clogged. It is also not uncommon for drain lines to become dislodged or outdoor drain line components to become obstructed. When this happens, your condensation pan will overflow, causing water to leak into your home.
• Broken Condensate Pump
  In homes with basements, a pump assists in the removal of water from your system. If this pump breaks, water will leak into your basement. Because this area of the home is not commonly frequented, extensive damage could occur before you notice drainage issues.
• Dirty Air Filter Leading to Frozen Evaporator Coil
  Dirty home air filters don’t facilitate adequate airflow over the evaporator coil. Without proper airflow, the coil gets too cold and freezes. When this ice melts, dripping into the condensation pan, it can overflow.
• Low Refrigerant Charge
  If your system is low on refrigerant, this can also cause the evaporator coil to freeze, which likewise can result in an overflowing condensation pan as ice melts.

7 Signs You Need a Dehumidifier

Summer stickiness can sneak up on you, taking a toll on your comfort,  health, and the structure of your home. Is your home in need of dehumidification action?

7 Signs It’s Time for a Dehumidifier:

1. Sticky, stuffy home feel.
   Relative humidity levels over 60% are too high, creating a sticky summer home environment, even with air conditioner use. Not sure of home humidity levels? Upgrade to an Ecobee or Nest smart thermostat with built-in humidity reading capacity, or purchase an inexpensive humidity meter separately for $10-12.
2. Musty odors.
   Musty odors go hand-in-hand with high humidity levels. As mold, mildew, and bacteria grow in this environment, offensive odors are released.
3. Condensation on windows and wet stains on wall/ceilings.
   Condensation on windows and wet stains on walls and ceilings can quickly lead to water damage and mold spots in these areas if moisture buildup remains unaddressed.
4. Mold and mildew.
   Bathrooms are a prime locale for mold and mildew, especially when adequate ventilation isn’t used during showers. What can start out as a few small spots can quickly spread, creating not only an ugly site, but effecting the health of your family if toxic black mold species stachybotrys chartarum proliferates releases mycotoxins.
5. Water damage and rotting structural components.
   If you see water stains on ceilings and walls, it is wise to immediately begin investigation into what is causing moisture buildup. You could have a hidden plumbing system leak. Left unaddressed, the structural wood framing of your home can become permanently damaged over time, drawing pests that love moisture and rotting through.
6. An abundance of pests.
   Because, bugs love moisture, high humidity levels draw destructive pests like termites and carpenter ants.
7. Upper respiratory issues.
   If you and your family are constantly sneezing and coughing, high humidity levels in the home could be to blame. Dust mites, pests, mold, and bacteria that negatively impact health are attracted to moisture, propagating and irritating allergic and sensitive individuals.

Where’s All The Excess Moisture Coming From?

Showering, cooking, and even breathing can release moisture into your home, where it can build up due to a tightly sealed building envelope. Though cooling units can remove some of this moisture, it may not always be efficient in doing so, especially in fair weather days when your air conditioning isn’t on. Since your air conditioner can’t measure humidity, people also tend to overcool their home in their efforts to reduce humidity levels, thereby increasing energy costs. Adding a whole home dehumidifier can more efficiently remove moisture from the air in your home, closely monitoring humidity levels and using as much as 80% less energy than your air conditioner.

How Much Can A Dehumidifier Help?

A whole house dehumidifier added to your air conditioner or heat pump can help you ensure comfort and prevent moisture-related problems in every conditioned area of your home, keeping humidity levels in the home to 30-60%, the level recommended by the U.S. E.P.A. for health and comfort.

What's the Best Summer Thermostat Setting?

It can be tempting to crank the temperature setting on your air conditioner down in the summer heat. Unfortunately, this can lead to shockingly high energy bills. Luckily, with a proactive approach, you can find a thermostat setting that ensures both home comfort and affordable energy bills.

What’s the Best Summer Thermostat Settings?

• When You’re Home
  78-degrees Fahrenheit is the temperature setting recommended by air conditioning companies and the U.S. Department of Energy to help you stay cool and comfortable while avoiding an abnormally high electric bill.
• When You’re Away
  Turning your thermostat up to 7-10-degrees, to 85-88-degrees Fahrenheit while you’re away, offers significant savings. Those who make this adjustment whenever they’re away from the home for more than 2-hours could save up to 10% on cooling costs.

Tips For Getting The Most Bang For Your Air Conditioning Buck

If the temperature settings above leave you wanting more, look to our tips for making the most of summer air conditioner use.

• Enlist the help of a programmable thermostat.
  If the thought of keeping up with ever-changing home thermostat settings wears you out, enlist the help of a smart programmable thermostat. There are many affordable models available to help you balance the comfort and energy savings goals of your family.
• Don’t air condition the entire neighborhood.
  Sealing leaks can help keep cool, conditioned air inside your home. Check your home carefully, installing weather stripping or applying spray foam or caulk around windows and doors, outlets and wiring, and around plumbing fixtures.
• Keep the heat out.
  Enlist the help of heat and sunlight deflecting window treatments, especially on west and south facing windows.
• Cook smart.
  Avoid using appliances that generate heat, like the oven and stove, until the cooler morning and evening hours. Better yet – cook outside on the grill.
• Lose the covers.
  At night when you go to sleep, lose the covers and don light pajamas, setting your thermostat to a higher temperature setting of 80-degrees or more.
• Install ceiling fans.
  Heating and cooling companies know energy efficient ceiling fans can make occupants in the room feel up to 7-degrees cooler than the ambient temperature thanks to the ‘wind chill effect.’
• Monitor humidity.
  Your body struggles to stay cool when humidity levels are high (over 60% relative humidity), as the added moisture in the air makes it difficult for sweat to evaporate and cool off your body. If your home is constantly muggy, adding a whole house dehumidifier can help you gain control of excess moisture using much less energy than your HVAC system. This can allow you to raise the temperature setting on your thermostat and remain more comfortable at higher temperatures.
• Upgrade your system.
  If your heating and cooling system is a dinosaur, you’ll see a significant comfort improvement, coupled with surprising energy savings, when you upgrade to a newer, higher SEER energy efficient model.
