North San Diego County Heating and Cooling Services

Oak Island Heating and Air Conditioning can handle every aspect of your HVAC project from helping you decide if you need new equipment, to financing your project once we have completed it.

How can I know if I need a new system?

The primary factor to consider is the age and efficiency of your home’s HVAC system and air conditioner. If your heating and air conditioning system is more than 10 years old, your best option is probably to replace it with a new energy-efficient HVAC system. Most heating and AC systems are intended to have a useful life of 10 to 15 years if properly maintained.

AC Maintenance in North San Diego CountyOnce yours is older than 10 years, you will probably start noticing that it’s time to replace it and start enjoying lower energy bills.

Central HVAC Units

A central air conditioner or central HVAC system is the most popular and convenient way to cool your home. Central air conditioning units are usually combined with a gas furnace to provide heat through the same set of ducts. There are also central HVAC units called heat pumps that combine both the heating and cooling functions, which are much more energy-efficient when using electricity for heating instead of gas.

HVAC Installation

Replacing your current HVAC system is a very important decision. With higher electricity costs and the new high-efficiency heating and cooling systems, it usually makes sense to replace an older system. A new HVAC system will not only improve the comfort of your home, but it will also your monthly utility bills significantly – often as much as 50%! Call us today for a free consultation.
