Efficient air conditioning / heating only happens when
the condenser, evaporator coil, heater & line set ....
Are all matched, properly sized for your home & installed correctly!
PERIOD!
Heating and air conditioning equipment is very tightly engineered. Each piece will only operate efficiently at set parameters. To explain: Every inside coil (evaporator coil) is engineered for a specific air flow and BTU. This means the heater (furnace) must blow the air flow needed by the evaporator coil. No more and no less. But that also means the condenser must also deliver the amount of BTU's the evaporator coils is designed for too. This also means the line set must match. Plus the ducting must be able to handle the air flows too. When it all matches the whole system works at it's most efficient rate and it lasts longer.
Everything you need to know is all right here and it's accurate.
The following tells you what happens to your air conditioning and heating when something is wrong.
Plus the money you save by repair type. Statements are backed up by facts and studies!
These are common problems that increase air conditioning repair, power and replacement costs.
Knowing helps you make better decisions on any air conditioning repair, ac repair, heater repair, ducting or heater (furnace) issue.
What happens when air flow across the inside coil (evaporator) is too high?
When the air flow is too high for the air conditioning system your house will not be comfortable. The system cannot remove excess humidity and your home becomes cool but muggy. The air conditioning runs more often for shorter cycles, consumes more electricity, increases repair costs and wears out faster. Electricity bills can easily increase $200.00 to $600.00 per season.
What happens when air flow across the inside (evaporator) coil is too low?
When the air flow is too low as required by the air conditioning system your house will not cool well. The unit ices up, leading to early compressor failure. Valves wear out quickly. The whole system runs harder. It consumes more electricity, increases repairs and wears out faster.
What happens when the line set is 1 size too small?
If the line set is too small your air conditioning energy efficiency is reduced approximately 2 seer rating points. This translates to about $256.00 in extra electricity per season. * based on 12 cents per kilowatt hour for electricity and living in an area where air conditioning is required often. The compressor works harder and needs repair or replacement earlier.
What happens when the line set is too big?
Nothing, in fact it's okay! The compressor will be spared some work.
Dirt: A dirty system keeps on costing you money lots of it!
Dirty inside coils (the evaporator) from dust, hair, grease and pet fur just to name a few increase energy costs greatly. Dirt build-up cannot be prevented and must be removed. Dirty outside coils (the condenser) from dust and oxidization cost extra electricity. Dirt accumulation and oxidization, cannot be prevented and must be removed. A dirty non maintained system costs a minimum of 20% and more
often 30% extra electricity, adding many thousands of dollars of extra cost over the systems lifespan. A dirty non maintained system usually costs a minimum of $500.00 in extra repair costs over a maintained air conditioning system in the first 5 years. Extra repair costs escalate greatly with each passing year as do extra energy costs. Add the two up and it's big dollars you're spending needlessly.
Common system problems.
Leaky ducts cost big money all year long. Leakyducts cost about 18% extra electric costs for air conditioning. Plus a bigger system is needed! You spend more capital money on both air conditioning and heating equipment. Your heating bills are higher too! Because the system runs longer repair cost goes up too. BOTTOM LINE Have your ducts sealed or replaced once and enjoy the energy and capital savings for good.
Freon overcharge and undercharge cost energy and reduces system lifespan.
Low air flow kills systems and costs you much more energy.

Problems effecting air conditioning efficiency and comfort. These are actual problems in southern California homes today.
Money (energy) saved based on these 4 repair types.
What makes air conditioning comfortable?
In 1923 research identified the proper indoor comfort zone. Tolerance to heat is affected by the amount of humidity in the air. At higher temperatures humidity must be held lower to ensure comfort. Air conditioning can easily bring the temperature into the comfort range. In fact, bigger air conditioners virtually ensure that the temperature inside can be as low as we want it. But, cold alone is not comfortable. In fact, it is distinctly uncomfortable. To maintain comfort moisture levels must also be controlled.
This is best achieved by smaller, not larger air conditioners.
An air conditioners ability to remove moisture increases when it runs for longer periods of time. At the beginning of every cycle the air conditioner puts moisture into the house as water evaporates from the inside coil. Once its run for 3 minutes, it begins to remove moisture. Since a smaller air conditioner runs longer to keep the house at the temperature desired, it removes significantly more moisture than a larger unit. When compared against a 5 ton unit a 2.5 ton unit removes 21% more humidity, while still maintaining the set temperature! Plus you enjoy lower electricity costs and capital costs for your air conditioning and heating system!
The bottom line!
Kept clean, properly sized, properly installed air conditioning and heating systems cut energy costs, cut repair costs, cut capital and replacement costs.
Fact: your costs can be cut by many thousands of dollars over a ten year period! $12,000 to $24,000 is not out of the question*.
*average varies by house type, size, air usage habits, system age, repairs needed, quality of installation and other variables.
Big dollars under all circumstances. It should also be clear that EFFICIENT and EFFECTIVE Heating and air conditioning is only attained through an experienced, quality orientated air conditioning contractor.
Need more reasons to keep central air conditioning systems clean?
Fact: 9 out of 10 system failures are caused by dirt and dust. (LCES) Louisiana Cooperative Extensions Service.
Fact: Clean systems restore capacity and lessen running time. Translation: Savings on heating/cooling bills, repairs and replacement costs. (LCES)
Fact: A buildup of .042 inches of dirt on a heating or cooling coil can result in a decrease in efficiency of 21%. (EPA) Environmental Protection Agency.
Fact: Most commercially purchased fiberglass filters are only 7% efficient in stopping dirt, dust, pollen, etc. from passing through it. (ASHRAE)
Keep your Heating and air conditioning system clean and you save on gas, power, repair costs and premature replacement costs!
