Air conditioning units have seen a lot in terms of technological improvement, and it is now rare to have a significant system breakdown. If the system is, however, not cooling you as it always has or it is not warming up your room significantly, repair or replace it.
Since 2010, AC system manufacturers have been using a new form of refrigerant which is not only more efficient but also more environmentally friendly. By installing a new system, therefore, you will use half the electricity your old system was using and at the same time cool your house or warm it efficiently.
Audit the Efficiency of your Old System
If you have had an air conditioning unit that has lasted for more than ten years, repair is probably not an option unless it is suffering a simple problem such as clogging or torn fan belt.
The problem with old AC systems is that they suck up a lot of energy especially if they have been in operation for more than ten years. As of 2006, AC systems could operate at about 10 SEER, Seasonal Energy Efficiency Ratio. Old AC systems operate below 10 SEER with new systems operating at 13 SEER or higher.
This means that a new system will operate at 30 percent lower energy than an old system. A unit that operates at 16 SEER will allow you to save up to 60 percent on energy. If your old AC system is hiking your electricity bills, it is time to replace it.
How Is the Ductwork?
Even after upgrading to the latest and highest efficiency gear, you might not feel as cool as you need in hot days. The mechanicals forms a small part of the air conditioning system. The average ductwork leaks up to 30 percent of cool air before it gets to you.
You should have the ductwork tested for leakage before you consider replacing the central AC system. Your technician will seal the vents to see how much air escapes and advise on whether you need to replace your ductwork.
If the ductwork has a leakage, the technician will repair the gaps which will cost you up to $35 per vent or they might advise you to have the ducts replaced altogether.
How well is your House Insulated?
A poorly insulated house makes it challenging for an old AC system to function. By repairing the insulation system in your house, your AC will have a few more years to cool your house. Even better, a well-insulated house will need a smaller AC system which means that you can save on replacement costs by buying a small system.
Your air conditioning repair service technician will assess the building envelope and advise on whether to replace or seal gaps. The technician might also advise on building insulation into your walls to reduce your energy costs by up to 30 percent.
Replace Your System Today
When you are considering replacing your unit, ensure that everything is sized right for efficiency. This is why you need to hire a licensed and insured professional to do the job.
Replacing insulation system is better than replacing old air conditioning units, but sometimes you might need both. Audit your system today and repair common problems or replace old systems.
