When to Consider New AC Installation

If your air conditioner isn’t working as well as it used to, it’s hard to tell if it can be fixed or if you should replace it. Most reputable air conditioning installation companies will inspect your system and let you know if a new unit is the best option. You may need to replace your AC if:

  • It’s 10-15 years old. Air conditioners are built to last around 15 years or so. After ten years, it may start to need expensive repairs that add up quickly or begin to stop cooling your home as well as it used to. It often makes more sense financially to get a new one.
  • Your energy bills are high. Older air conditioners are not as efficient as new models, so if your air conditioner doesn’t have a SEER rating of at least 13, chances are it costs a lot to run it. The amount you could save on energy bills may be worth purchasing a new unit.
  • It uses R 22 Freon. The federal government is phasing out Freon to conserve energy, so Freon’s cost for AC units is rising. So if you’re having problems with your air conditioner requiring more Freon, most AC installation companies recommend replacing it.

Choosing the Best AC Unit for Your Home

Carrier AC Units from Crystal Heating & CoolingThe most important decision when choosing a new AC unit for your home is selecting the right equipment.

Understanding the correct size, type, and efficiency can help narrow down all the options.

Hiring a heating and cooling company is the best way to ensure all these critical aspects are considered.

Here are essential tips on choosing a suitable unit for you.

Consider The Size

Several factors affect the size of the unit you need including where you live, the amount of wall and attic insulation you have, your types of windows and doors and where they are located, and the orientation of your home to the sun.

HVAC contractors can perform a load calculation to reveal what size unit your home needs. Once complete, the contractor will recommend the right air conditioner size for your home using tonnage or Btu per hour.

For reference, one ton equals 12,000 Btu per hour.

Air Conditioner BTU Chart

To buy the right size air conditioner, reference these BTU calculations*.  A BTU, or British Thermal Unit, measures how much energy is required to raise a room’s temperature of one pound of water by one degree.  This calculation is critical to staying comfortable.

Every air conditioner and heater is rated to produce a certain number of BTUs.

This chart is a good starting point for sizing your AC installation.

[ Square Feet =  BTU’s ]

  • 0-150 = 5,000
  • 150-200 = 6,000
  • 200-250 = 7,000
  • 250-300 = 8,000
  • 300-350 = 10,000
  • 350-400 = 12,000
  • 400-450 = 14,000
  • 500-600 = 18,000
  • 600-700 = 20,000
  • 700-800 = 22,000
  • 800-900 = 25,000

* These BTU figures are estimates based on an average room for two windows, 1 door, and an 8-foot ceiling.

This analysis can also alert you to the benefits of upgrading your home’s insulation, which could increase energy efficiency and reduce the size of the AC unit your home needs.

Keep in mind an undersized unit won’t cool all your rooms completely, causing the team to run continually without keeping your home comfortable.

This will also cost you more to operate from both lack of efficiency and quick wear and tear on your unit from running constantly.

An oversized unit costs more to operate also, but this is because it generally takes more electricity. Large teams can also cause rooms to feel humid and damp.

The way AC is intended to work, a certain amount of air is supposed to circulate past the coils to extract moisture. If your unit is too large, it may cool the air too quickly without removing excess water.

Chose a Type of Air Conditioner

Carrier Ductless Mini-Split System

For most residential customers, there are two main types of air conditioning units most often used today.

  • Central Air Conditioner:  This unit cools multiple rooms at once.  It uses a split system that regulates air through your home’s ducts, often called a ducted system.
  • Ductless Mini-Split:  Provides good efficiency and does not require duct. This unit is best used in single rooms.  This system combines an outdoor unit comprising a compressor and a condenser with one or more indoor units mounted on a wall and equipped with air blowers.

Consider the AC Units Efficiency

Every air conditioning unit comes with a seasonal energy-efficiency rating (SEER).

This rating system rates how many Btu an air conditioner will remove for each watt of electricity it consumes.

  • Federal law requires a SEER rating of at least 13 on all new AC units.
  • Newer units with higher SEER ratings also include more safety features, better sound shields, and lower voltage requirements.
  • Typically, the higher the SEER rating, the less it costs to operate the unit.
  • However, a unit’s initial cost is generally higher as you get higher in the SEER ratings.

Using Furnace Ducts For Air Conditioning

It is possible to use your existing furnace ducts for air conditioning. But first, these ducts should be inspected. Modifications are often required to accommodate the larger volume of air that the AC unit creates. Typical modifications may include the following:

  • Upsizing the Furnace Blower – Most newer furnace blowers are smaller in size. You will need to ensure your blower is large enough to move the cubic feet of cool air required for your home.
  • Sealing the Ducts – An unbalanced system can lead to back-drafting during the heating season, which can be dangerous. It could also create pockets of warm air during the cooling season. Sealing the ducts will boost your unit’s efficiency and keep your home safe, but a professional should perform the job.
  • Swapping Out Supply Registers – Your current grill slits may be too small to allow the necessary air volume to pass through. New grills can allow more air to pass through, improving overall airflow by 15 to 25 percent.

Even if there is no ductwork in your home, a new ductless HVAC system would significantly improve your comfort indoors.

AC Installation AfterCare

You can do a few things after AC installation to ensure that it was done correctly, as well as extend the life of your new unit.

First, a good installer will check the thermostats, system sequence, refrigerant levels, and more once the installation has been completed.

Once the professional has checked off their list and everything is running smoothly, you should do a few things to keep your new AC unit running great.

  1. Let It Rest – Just like any machine, occasional rest is necessary to extend the AC unit’s lifespan. You can manually turn off your AC or automatically set up the unit to rest periodically.
  2. Change the Filter – A clean filter significantly impacts your home’s air quality. Changing the filter frequently can reduce the burden on your unit and lower energy consumption.
  3. Don’t Ignore the Outside Unit – Make sure to clean any debris around the unit and keep grass and weeds cut back.
  4. Get Regular Maintenance – A professional should regularly check the inside and outside equipment to ensure the unit is running correctly and to catch any issues before they become significant problems. Crystal Heating and Cooling have hvac maintenance plans as a convenient way to ensure your AC unit is getting the attention it needs.
