Understanding Air Conditioners
The majority of people buy or operate their heating and cooling appliances without fully understanding exactly what they need. If you don’t know anything about sizing, installation, maintenance, and correct use of HVAC equipment, you’re not taking the most cost-effective approach to owning and operating your appliance.
How Air Conditioners Work
Air conditioners cool your home using a cold indoor coil called an evaporator. The hot outdoor coil (condenser) collects the hot air inside your home and releases it outside. A piece of serpentine tubing connects these two components, transferring refrigerant between them.
The main types of air conditioners are room air conditioners and central air conditioners.
Room Air Conditioners
As their name suggests, room air conditioners are built to cool individual rooms rather than an entire home.
When they’re used to provide cooling to a specific room instead of a larger space, they’re less expensive to operate than a central unit, though their efficiency may not compare to their central counterpart.
Central Air Conditioners
Central air conditioners cool your air using a series of supply and return ducts in your home. Supply ducts and registers (grill openings in the walls, floors, and ceilings) transfer cool air from the air conditioner to the home.
A packaged central air conditioner integrates the evaporator, condenser, and compressor all into one convenient cabinet, usually located on a concrete slab adjacent to your residence’s foundation. These types of units usually include heating coils for a natural gas furnace, eliminating your need for a separate heater or furnace.
Air Conditioning Problems
Common causes of air conditioner failure include:
Buying and Sizing New Air Conditioners
Nowadays, the top air conditioners are the market use 30% to 50% less energy to produce the same amount of cooling as their predecessors. Since the 1970s, the many manufacturers of the HVAC industry have made major strides in increasing the efficiency of heating and cooling appliances. Even if your unit is only a decade old, you may be using up to 40% more energy than you would be had you replaced it with a newer, more efficient model.
Air conditioners are rated by the number of British Thermal Units (BTU) of heat they are able to remove per hour. Another common unit used to measure air conditioning size is “ton”, which equals out to 12,000 BTU per hour.
With that being said, the deciding factors for the size of your next air conditioner should be...

Choosing a Contractor
Deciding which contractor to work with can sometimes an incredibly tough decision. There are so many HVAC technicians to choose from nowadays, and not all of them offer the same level of service.
Don’t hesitate to ask for references when choosing a contractor. A quality serviceman should have a proven track record of keeping customers satisfied and happy with the level of service they receive.
A written warranty that covers their workmanship is also a good sign that they’re deserving of your business. Quality technicians should be willing to stand by the work they do, and the ones who aren’t may not be able to provide you with the results you need and deserve.
Also, be wary of technicians who are constantly trying to up-sell you on different services and products. It’s a contractor’s job to inspect your system, and try to identify malfunctions, pain points, and problematic areas that an owner should know about. This allows you to receive an in-depth look at your HVAC system so you’re always in the loop and aware of any potential repairs or replacements that need to take place.
However, no technician should constantly badger you about upgrading your furnace to a bigger size or purchasing expensive add-ons to your current system. It varies depending on the job, but proceed with caution when analyzing your service recommendations.
