Signs You Need A New Furnace Installation

1. Utility bills on the rise – All HVAC units will get a little bit less efficient as time goes on. What this means is that the indoor air temperature will remain the same but at an increased cost off your utility bill because of the increase in inputs it takes to achieve that same level of output.

2. Old age – On average, furnaces last about 20 years depending on use, environment, maintenance and brand. If yours is much older and breaks down, you should reconsider any repairs and consult our furnace installation team instead.

3. Repair after repair – While we will always be happy to come in and fix your unit, you shouldn’t require furnace repair every season. If you’re getting to know our repair team by name they’re over so often, save yourself the trouble and consider a new installation that won’t need as many repairs.

4. It won’t turn on – There’s no more clear sign that you need to call in our St. Louis furnace installation team than a unit that won’t turn on. First, check that the pilot light is lit its usual color and then if it’s an electrical unit try testing the outlet with another appliance. But if your unit is dead, a new one is necessary in the Midwest winter so give us a call.
