Furnace questions.
Why is my furnace blowing cold air?
A thermostat setting, the ignition or airflow can cause it. A technician checks the furnace at the property before naming a repair.
Should I repair or replace my furnace?
If a repair is impractical or a major part has failed, Air Plus can quote a replacement. You get the repair price before any work begins.
Do you install furnaces?
Yes. The installation plan accounts for the ducts, the controls and the space around the equipment, and the quote lists the equipment and the scope.
How much does a new furnace cost?
It depends on the equipment and on any duct, control or electrical work. We review the home first, then quote.
Should I consider a heat pump instead?
A heat pump heats and cools with one system. We can quote either so you can compare.
