You'll want them high up on a wall and in a position that enables them to blow air clearly across the width of a room. Generally, you'd be looking at three or four metres of piping, otherwise your installation costs may be higher. Your outdoor unit should ideally be in a sheltered position, and attached to a wall with brackets or on a concrete base.
If you have limited outdoor space for units, you may consider a multi-split air-conditioning system that can connect several different indoor units to a single outdoor unit.
CHOICE tip: If you live in a strata-managed apartment, you'll probably need approval from your body corporate to install air conditioning.
If you have an old system, or a broken one, it may be time to upgrade or replace it. The average lifespan of an air conditioning unit is 15 to 20 years. New models are much more energy efficient than older units, so by installing one you should be able to save money on your energy bills in the future. It's usually cheaper to replace older air-conditioning units than to install a completely new system.
This is because the installer can usually use the same pathway for the piping, so there's less need to drill holes through walls or pour a concrete base. New models are much more energy efficient than older units, so you should save money on your energy bills. However, the old piping will usually need to be replaced, as new systems may use a different refrigerant gas that operates at different pressures and requires different piping, or the old piping may be contaminated or damaged.
For new installations, the warranties usually require new piping to be used. In some cases, it may be possible to reuse the existing piping after it has been flushed of any oil and refrigerant residues. Your installer can advise if this is the case, but make sure to check that the warranty will still be valid. Remember: there might not be much cost saving between cleaning and reusing the old pipes compared with installing new ones.
Chris's first bit of advice is to do your research and plan ahead before the heat or cold kick in. It's also a good idea to get at least two quotes if you can. Pros: The popular option, it offers a 'one-stop shop' where everything is handled for you. Cons: You could be restricted to using a certain brand or type of air conditioner. Expect much better comfort and reduced temperature swings compared to your older single-stage system. Expect considerably lower utility bills than your older existing single-stage system.
Almost Always: Variable-speed inverter driven compressors, variable speed motors inside and outside, and the most premium features available on the market. Expect significantly better comfort and virtually no temperature swings. Expect significant energy savings compared to single-stage and even dual-stage existing systems. These systems almost always include high-end Wi-Fi controls and are practically silent inside and out. Remember, the level of difficulty also plays a role in the installation price of your new air conditioning system.
Refrigerant lines, plenums, condensate drain systems, controls, thermostats, zoning dampers, etc. Are we talking about a Ford Focus or a Bugatti Chiron? There are two main types of rooftop air conditioners; packaged or package units.
The trend in newer homes seems to be going back to installing split air conditioners. The price range tends to be lower than split systems for two reasons. First, the highest efficiency package heat pump or gas pack is 16 SEER, so there are fewer options. Second, there are many less labor hours and access issues associated with rooftop units. Usually: Single-stage compressors, ECM or variable speed motors , and upgraded features. Living in Phoenix, AZ, without air conditioning is not an option.
Did you know there is another option to cooling and heating your home other than central air conditioning? Since clean and adequate airflow is critical for humans, air conditioning system installation is regulated, and professionals must obtain proper training and licensing. AC units use a cooling chemical called Freon that installers are trained to handle to prevent contamination or accidental spills.
Be sure to review the installation contract to understand what local and federal regulations apply to avoid potential fines for improper installation. Warranties generally cover parts and equipment, but the installer may also offer a warranty for labor on repairs that fall within a specific period. Extended warranties might also be available, but these often cost more than any standard repairs that could occur over the lifespan of the AC unit.
When it comes to installing a whole air conditioning system, as opposed to small window units, there are two types of AC units you can choose from. Central air conditioning with ductwork is the most popular choice for homeowners who are ready to install a complete HVAC system to maintain a comfortable temperature throughout the year.
A ductless split system is another excellent choice that can be installed in specific rooms without ductwork—even if a heating system is already installed in the house.
A central system involves installing an HVAC system in a mechanical room with a small amount of plumbing and electricity available to operate the equipment.
Using ductwork, a central air system pulls air from large areas of the house, filters the air, then cools it before blowing the cool air back into the house through the ductwork and vents. Most air filters should be replaced every few months to ensure the system can flow clean air into the home without stirring up excess dust or allergens. Ductless split systems use a condenser and compressor unit installed outdoors and an evaporator installed indoors.
Sometimes this indoor evaporator is already used to heat the house. The more zones you want to cool, the more this system will cost. Central AC units eventually wear out just like any other mechanical equipment.
An older unit should be replaced to regain energy efficiency, improve cool air output, reduce humidity, and more. Most central air conditioner systems have a lifespan of 10 to 15 years.
Without proper maintenance like changing air filters or having it serviced regularly, it may wear out sooner. Older units are less efficient than newer models, so the quality of cool air may significantly improve with installing a new unit. AC units that grow noisy usually mean they have outlasted their prime or have a ductwork problem. Noises may result from ductwork that is not large enough to handle the square footage of the house or from an inner coil that has worn out.
Constantly finding dust around the house is another indicator that there is leaking ductwork. The motor and other parts may not operate at the same capacity as before, so the system runs more often to compensate. Replacing the central AC unit should solve this problem. AC units are designed to remove excess humidity, which is typically associated with a warmer sensation. Do this quick calculation to help you decide: Multiply the total cost of repairs by the age of the system.
A broken-down or worn-out AC unit can be a significant deterrent for prospective home buyers, especially in hot climates. The type of cooling system selected will depend on the area that needs to be cooled.
Adding new rooms will require an update to ductwork and potentially a new AC unit. If the cooling system is too small to handle the addition, it will run more frequently, reducing its lifespan and increasing your energy bill. Only trained and licensed technicians are allowed to handle this chemical.
Professional installers can adequately measure your home to determine the best ductwork layout and unit size to cool your house to a comfortable temperature. Central AC unit costs can feel overwhelming.
The cost to install a central AC unit in a new house is less daunting since central AC unit costs are typically built into the project in most areas. No matter which situation applies, here are some ways to save money on AC unit installation costs. An in-person consultation will help the technician understand your needs and map out the best system. To feel more comfortable discussing your project, consider asking any of these pertinent questions about central AC unit costs.
