Let’s examine in more depth why selecting an appropriately-sized AC is of such paramount importance.

Why Choosing the Right AC Matters?

No matter which air conditioning system you select for your home, selecting an AC unit of appropriate size is key to realizing its full value and not wasting energy. AC units don’t come standard-sized; their dimensions depend on individual circumstances.

Issues with an Oversized AC Unit

An oversized AC unit:

Your home’s humidity may not be being effectively dehumidified because your AC system hasn’t run long enough to have any significant impact on humidity levels.

Frequent short cycles can significantly shorten the life of your AC unit. They also require additional maintenance costs and create an environment which your household cannot fully enjoy.

An undersized AC unit:

  • An inadequate AC unit: it could cause hotspots in your home as it will not provide sufficient cooling in all rooms.
  • Dehumidifying your home efficiently requires running it for extended periods, at lower temperatures, to remove more moisture than necessary and reach low humidity levels.
  • Increased energy costs could result from the repeated cycles necessary to reach desired temperatures in your home.
  • Your AC unit’s lifespan could be reduced, leading to more breakdowns and service calls than necessary.

Finding the Right AC Size for Your Home: Things to Consider

Homeowners should seek help from an HVAC specialist such as serviceairconsingapore.com when selecting an AC unit suitable to their square footage. Deciding upon an ideal unit requires more than simply knowing its dimensions; there is much more involved when choosing the ideal air conditioning unit than simply knowing its size.

Some important variables in AC unit selection include:

  • How much direct sun does your home receive?
  • Your windows contribute directly to energy use in your home, so take steps to maximize both their number and efficiency in terms of energy savings.
  • Effective air circulation systems
  • Insulation plays an essential role in energy conservation.
  • Fireplaces, home heating elements or wood stoves that contribute to cooling or heating loss.

HVAC technicians use something known as the Manual J calculation to select an air conditioner size suitable for homeowners.

The Manual J Calculation

HVAC technicians utilize the Manual J calculation to assess the heating and cooling requirements for residential or commercial properties. As with any formula, using accurate data is key in this calculation; HVAC technicians take precise measurements throughout a house while frequently conducting tests to gauge insulation effectiveness or seal quality on windows or doors.

The basic elements of the calculation include:

  • Property or home square footage.
  • Insulation requires evaluation and rating before use can begin, so here’s some guidance on this front.
  • How many residents reside there.

HVAC technicians can use this data to assign an exact number of British Thermal Units (BTUs). BTUs measure how much heat will increase water temperatures – in this instance they allow for heat sources such as windows, people and doors.

Calculating the AC Unit Load

AC load refers to the total output required to effectively cool a home, calculated as follows.

  • (square footage) x (ceiling height) x 20 BTUs
  • (number of occupants) x 100 BTU
  • (number of entry doors) x 1,000 BTU
  • (number of windows) x 1,000 BTU

After adding up all the BTUs from these calculations, your technician can estimate the AC unit load necessary to power your home and suggest an ideal AC size unit for you.

How Are AC Units Measured?

AC units are measured in tons. Residential air conditioning systems that weigh 1 to 1.5 tons typically fall in this category. To accommodate larger homes (those over 4,000 square feet), more powerful residential AC systems may weigh 5 tons each.

What Are the Benefits of Scheduling an AC Tune-Up?

An air conditioner tune-up service will pay dividends over time, with this list of savings tactics:

Improve Your System’s Efficiency

A comprehensive tune-up involves cleaning, testing, and then making adjustments to ensure maximum effectiveness of the entire system. Air conditioners lose effectiveness over time without proper care; without it being maintained regularly this decline can accelerate more rapidly than otherwise. Optimizing performance of your air conditioning is vitally important to both lowering energy bills as well as keeping your home cool more quickly and evenly!

Avoid Emergency Service Calls

Avoid unexpected system failure by scheduling preventative maintenance annually for your air conditioning. By staying informed and ahead of any emergency repairs that could cost a bundle, preventive maintenance could save both you and your wallet time and money in repairs that otherwise would have come at the unexpected.

Fix Small Problems, Skip Big Ones

Air conditioners can be complex systems, and even minor issues that seem simple enough to solve can become expensive and complex if left alone. Even if your AC seems fine at first glance, internal issues could still be lurking within. Tuning your system annually to check for problems may help identify them early and save you money in repair bills down the line.

Give Your Air Conditioner a Long Life

Poor maintenance of your air conditioning unit can reduce its lifespan significantly and cost thousands in repairs over its lifespan. Regular tune-ups could extend its life, saving money over the life of your home ownership.

Can I Tune-Up my AC Unit Myself?

Tuning-up your AC should only be undertaken with professional guidance from qualified HVAC technicians. Although you can help ensure proper operation by regularly replacing air filters and clearing away dust around the outdoor unit, most AC tune-ups require an expert who has received certification to do the work properly.

You Could Damage Parts or Get Injured

DIY attempts at tuning-up could result in disaster, from cleaning the condenser improperly to inadvertently damaging its delicate fins and coils – not to mention potentially receiving an electrical shock unintended! Even for something as basic as cleaning it yourself should be left to professional service providers for safety’s sake.

Trained Professionals Can Foresee Problems Before They Arise

Your HVAC technician provides experienced eyes that can help identify potential larger issues before they arise. We advise making an appointment with an HVAC specialist for all of your AC maintenance needs; ask what’s going on with it now and what could happen in future years.
