AC Installation & Replacement

AC units don't last forever. If your air conditioner has been breaking down frequently, needs a significant repair, or has just been costing too much in energy bills, it is probably time to replace it. The average lifespan of an air conditioner is only 10-15 years — if you know that your unit is at or approaching that age, you may want to start considering your options before your AC breaks down when you need it most.

Our technicians will give you a free estimate on a new unit. They will consider your home's dimensions and layout to ensure that the new AC is appropriately sized to keep you and your family cool.

Air Conditioning Repair

If you hear unusual noises coming from your air conditioning unit or it's simply not keeping the room cool the way that it should, it's time to call in a professional for repairs. Here are a few common problems that you should be aware of so that you can schedule an appointment right away:

AC won't turn on
Unit not blowing cold air
Leaking refrigerant
Making unusual noises
Leaking water outside

Repairing these issues with your AC unit early can help you avoid a bigger problem down the line, and it may mean you won't need to replace your air conditioner, saving you a major expense.

AC Maintenance

Just like you get regular maintenance on your vehicle, you should schedule a yearly tune-up for your air conditioner, as well. Certain parts need to be replaced after a while, such as the filter and coils. The condensate drain and other components may also need to be cleaned, as dirt and other debris may build up over time. Scheduling AC maintenance ahead of the start of summer will ensure that your unit is ready to keep you comfortable throughout the hottest months of the year.
