Common Questions
We Get Asked
What is a mini split A/C system?
A mini-split system A/C is basically a small ductless version of a heat pump & air conditioning central air system. What this means is, there are no ducts to put in the wall, and minimal temperature loss as air moves through ducts. The heating/cooling is directly at the mini split head. If you want to know why this technology is very cost effective and worth installing. read our article “Why a Mini-Split Is A Smart Move“.
Should I leave my mini split on all the time in summer?
For most mini split systems, it’s actually more efficient to let them run continuously during the summer. Keeping the system on allows it to maintain a steady, lower speed instead of shutting off and turning back on, which can use more energy to cool your home from scratch.
Do mini splits use a lot of electricity?
Mini splits are designed to be highly energy efficient and typically use less electricity than traditional central air systems. Because they avoid the energy losses that come with ductwork and use advanced variable speed compressors, they can cool and heat your home more effectively while keeping your energy bills lower.
What are common problems with air conditioners?
- Disrupted Airflow: Cause: Closed-off rooms disrupt airflow through the home.
- Installation and Maintenance Problems: Faulty Installation: Can result in leaky ducts and low airflow.
- Checking Your System: Initial Check: If the system fails, check fuses or circuit breakers.
Why is my AC running but not cooling?
If your AC is running but not cooling, it could be due to a dirty air filter, incorrect thermostat settings, a malfunctioning thermostat, a refrigerant leak, dirty condenser coils, blocked vents or ducts, a faulty compressor, frozen evaporator coils, or electrical issues.
Split System Comfort
Split systems are heating and cooling setups that include an outdoor unit connected to one or more indoor units. They move refrigerant through lines between the units to deliver heating or air conditioning directly into your space. Split systems are a popular choice because they’re efficient, quiet, and give you flexibility to control the temperature in specific areas of your home. They come in many types, from ductless models that don’t require any ductwork to traditional systems that use existing ducts. At Cas Pro, we install and maintain all kinds of split systems to keep your home comfortable year round.
