Air Conditioning Information for Tucson HVAC

If you’re in the market for air conditioning service in Tucson, Intelligent Design Air Conditioning & Heating wants to be your go-to company for heating and cooling. Many homeowners wait until there is a problem before seeking HVAC servicing. Here’s why that’s problematic.

Your Air Conditioning Unit Needs Semi-Annual Servicing

They say that you don’t miss the water until the well runs dry, and your AC unit is out of sight and mind — as long as it’s working well. But in the heat, even an hour without air conditioning can be miserable.

Save yourself unnecessary problems by having your unit serviced each spring and fall. This also may keep your warranties intact, as manufacturers often insist on twice-a-year servicing to make sure all components are working as intended.

Do I Need to Keep Adding Coolant?

If you keep having to add refrigerant to your system, you likely have a leak. We can send an air conditioning technician out who knows how to trace and repair coolant leaks to save you money.

Get Your Repairs Done Only by Certified Technicians

Our certified technicians know which potential problems to target first when your central heating and cooling unit quits working. That saves you money on repair bills and gets you cooled down faster. We also will clean and filter your central air unit to delay the onset of inevitable wear and tear on the system.

About A/C

Your central air conditioning system is made up of four main components including an air handler, an evaporator coil, a condensing coil, and air ducts which deliver the air to individual rooms throughout your home. All of the components of your air conditioning system need to be carefully matched together during the original installation. A mismatched system will operate poorly, and in some cases will not operate at all.

Parts of the System

The Air Handler: Blows air through the evaporator coil and into the ductwork to be circulated throughout the home. An air filter should always be located on the intake side of the furnace to clean the air before it is cooled and circulated throughout the home. When the furnace is used for air conditioning its blower will be energized in high speed which makes more noise and moves more air than when it operates in the heating mode.

The Evaporator Coil: Sitting on top of the furnace and enclosed in an insulated sheet-metal box, the evaporator coil is connected to the outside condenser by two copper tubes, one of which is insulated with a thick rubber coating. Refrigerant (R-22 or R-410a) will circulate through this coil to cause the cooling effect.

The Condenser: The outdoor unit of a split system is the condenser. It consists of the compressor, which is a pump that circulates the refrigerant through the evaporator coil, a large radiator coil to transfer heat, and a fan to blow air through the coil to keep it cool. It is important to keep the area around the condenser clear so it can operate properly.

The Air Ducts: Today’s ductwork in Tucson homes consists of insulated flexible tubes that snake across the attic floor or under the house. Unfortunately, the ducting system is out of sight and therefore out of mind and tends to be neglected when it comes to cleaning and repair. A recent study by the Arizona Energy Commission concluded that the average home loses up to 30-50% of the cool air before it ever gets to the rooms where it’s needed due to leaking ductwork. You could be overpaying the utility companies by as much as 30-50%.

Size Matters

Your system needs to be properly sized for our home. The size of your central air conditioner is measured in tons of refrigeration. One ton is equal to 12,000 BTU’s/hour of cooling capacity. A three-ton system, for instance, would have 36,000 BTU’s of cooling capacity. Too small a system will not cool your home adequately on hot days. And too large a system will cool the air in your home so fast that the humidity is not removed, leaving you with a sometimes cold, clammy feeling and, in severe instances, humidity condensing into water and dripping off of your air registers. Your comfort consultant will perform a heat gain analysis on your home to help you decide on the system that will best meet your needs.

SEERs

SEER stands for “Seasonal Energy Efficiency Ratio”, and they are not created equal! SEER is a number by which you can compare the efficiency ratings of different air conditioners. The minimum rating allowed today is 14 SEER and so every equipment manufacturer had to produce a 14 SEER unit. Don’t be fooled into thinking that all 14 SEER units are the same. The differences become apparent when you look closer at things like construction, quality reliability, durability, and enhanced warranties.

Nothing Lasts Forever

A good rule of thumb is that your cooling system will last about 10-15 years especially air conditioning systems here in Tucson, AZ. Once it hits that age you should consider replacing it, even though it might still run and blow cold air. Installing a new high efficiency system could cut your electric bill up to 60% when compared to the cost of running your old system. With a savings like that, along with all the federal tax credits, and factory and utility rebates that are offered frequently, it simply doesn’t make sense to keep using it.
