A full AC inspection should at least include the following steps:
1. Opening of the casing to determine the compressor’s performance, electrical components’ condition, and refrigerant levels.
2. Detailed visual inspection of all internal parts for signs of deterioration or damage.
3. Perform a manual test on the compressor for any sign of operation.
4. Test the electrical components and wiring of the AC unit for functionality and any signs of damage or deterioration.
5. Check refrigerant levels that should appear in an isotherm curve when testing properly with a manifold gauge set or vacuum pump. The minimum pressure for most residential AC units is around 200 psi, while the maximum is about 350 psi for most teams.
Should You Buy an Expensive Air Conditioner?
Ideally, you should get the most expensive AC unit that you can afford. Large Expensive units usually have greater energy efficiency and more features than cheaper units. Plus, costly units typically last longer. In addition to a warranty of one year on parts and labour, some costly models come with extended warranties in case something goes wrong after the first year.
Is Repair An Option For You?
Before getting any repair, you must determine if the AC unit is still under warranty or expired. If your unit is still under contract, get in touch with the manufacturer for advice and find out where they should be sending their technicians for repairs. Get a written estimate from each of the companies before hiring a contractor to get the job done.
Also, get an estimate from your local residence hall or apartment office if you can avail of their free AC inspection service once every season. If a warranty does not cover your unit, check out reviews about contractors on popular review sites like Yelp and Angie’s List. This way, you can at least get a better idea about the quality of service you will be getting from any contractor.
