Frequently Asked Questions
Once a year cleaning is recommended, failing to clean once a year can cause the outdoor coil to build up with dirt and put strain on the compressor and make the unit work harder. Even though the unit may look clean it’s better to have a professional service the unit once a year.
Most common reason for freezing up is a dirty filter, it’s very important to have a clean filter to allow adequate air flow. With older systems they also could have a small refrigerant leak in the system which would as well cause the unit to freeze up.
All Air conditioners have a Seasonal Energy Efficiency Rating (SEER). The higher that number is, the more efficient the unit is. The current industry minimum of new air conditioners is 13 SEER, but State-of-the-art equipment can reach a SEER rating as high as 21.While the initial cost of the latter may be higher, the lower monthly operating cost will save you money over the lifetime of the system.
The duration of an air conditioning installation can vary depending on the type and size of the system, as well as any required ductwork modifications. Most residential installations are completed within one full business day. Fortis technicians will assess your home, discuss the best equipment for your needs, and give you an estimated timeline before the work begins.
For best performance and efficiency, it’s recommended to have your air conditioning system professionally serviced at least once a year, ideally in the spring before peak cooling season. This includes cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring proper airflow — all of which help prevent breakdowns and extend the life of your unit.
