When does your HVAC need replaced?
There are some tell-tale signs that a new HVAC would help make your house more comfortable and likely help on energy costs, too. Loud or grating sounds coming from your furnace or AC may be signs of a serious malfunction. Frayed or exposed wiring can sometimes be safely repaired, but may also indicate more serious problems. Your current HVAC may be using older refrigerant, like Freon, which is being phased out. Even so, older HVAC systems are less efficient, and more expensive to operate, so it may be worth installing a new system to take advantage of the cost savings in energy efficiency.
