Read our FAQs to common questions
How often should I have my air conditioning system serviced?
It’s recommended to have your air conditioning system serviced at least once a year, ideally in the spring before it gets hot out. Regular maintenance keeps your system running efficiently and can prevent unexpected breakdowns during the hottest months.
How often should I change my AC filter?
Most HVAC filters need to be changed every one to three months. However, be sure to check the filter manufacturer’s recommended replacement frequency when you get a new filter, as it can vary depending on the filter’s thickness and efficiency (this is expressed as MERV, or minimum efficiency reporting value).
How long do air conditioners last?
While it depends on a number of factors, including the type of air conditioner you have, your climate, and how well the unit is maintained, the average lifespan for an A/C unit is 10 to 20 years.
How do I know if it’s time to replace my air conditioning system?
If your air conditioner requires frequent repairs, isn’t cooling your home efficiently, or is over 10-15 years old, it might be time to consider a replacement. Upgrading to a new, energy-efficient HVAC system can lower your energy bills and keep your home at the optimal temperature.
When should I contact you for A/C repair services?
As soon as you notice that your air conditioner is malfunctioning, turn it off. Continuing to run it when it’s broken could cause more damage and compromise other components of your HVAC system. Some of the signs that your air conditioner needs to be repaired include:
- Odd noises within the unit
- Water leaking from the unit
- Poor indoor air quality
- Weak airflow
- Odors or a burning smell coming from the AC
- Rising energy bills
- Warm or hot air coming out of the vents
What is a ductless split air conditioner, and how does it work?
A ductless air conditioner, also called a mini-split, is a type of energy-efficient cooling system that doesn’t require ductwork to operate. It consists of an outdoor unit that connects to one or more indoor units that can be mounted on walls, floors, or ceilings. The indoor unit pulls in warm air from the room and sends out cold air. The warm air is transferred to the outdoor unit. The benefit is that each indoor unit operates independently, so you can customize cooling in different areas of your home. Ductless split air conditioners are also perfect for homes without existing ductwork.
What should I do if my air conditioner stops working during a heatwave?
If your air conditioner stops working, check your thermostat settings and battery. Take a look at your circuit breaker and fuse box to verify the power supply and check the filters to rule out any obvious problems. If that doesn’t work, contact our team for emergency air conditioner repair services. We’re available 24/7 to quickly restore your home’s cooling.
