Goettl Technician replacing duct filter

Can I Install a New Furnace and Still Use My Pre-Existing Ducts?

The ductwork in your home is probably extensive, running through walls, under floors, and through crawlspaces. If you need to replace your current furnace because it has broken down, or perhaps has lost too much efficiency, you won’t want to go through the extra work of replacing your current ductwork system to accommodate the new furnace. People often wonder if new ductwork is a requirement for a furnace installation.

The answer is: “Usually not.” We’ll look into how this works. But for a solid answer, you’ll need to talk to an HVAC technician who can look over your house and your current furnace. Call Goettl Good Guys Air Conditioning today and learn about what you’ll need for a new furnace installation in Marana, AZ.

You won’t need to replace your ductwork if…

You are installing a furnace similar to your current one. Your new furnace will likely have a higher efficiency rating than your old one (advances in technology have made furnaces more energy efficient in general) and include more features, but it can use the same ducts without any complications. Your installers may need to make some adjustments at the connectors, but nothing more extensive than this.

Even for most high-efficiency furnaces, you won’t need to replace any of the ductwork. Have the installers perform duct testing along the ventilation system to spot leaks or other places where the ducts might lose heat. This will give the installers an idea of how well the ductwork will handle a high-efficiency furnace. If you have taken good care of the ductwork over the years, you can expect few problems.

You may need ductwork replacement if…

The ductwork is extremely old and/or in poor shape. If you’ve experienced trouble with leaking ductwork before and have needed numerous sealing and repair jobs done, then you should consider at  least having partial ductwork replacement. HVAC installers can perform the same duct testing to find just how leaky the ducts in your home have become. Based on this, they can provide you with an estimate of how much work needs to be done to make sure that your new furnace can live up to its efficiency rating.

As part of an annual maintenance contract a technician was dispatched to service the furnace. The veracity of the alleged service problems is indeterminant, but what ensued was a scare tactic laced, relentless pressure induced attempt to make a spot decision to replace the entire furnace. Nobody is so naive to think these are not upsell opportunities for the vendor, but this technician far exceeded the realm of reasonable and did not relent when asked. It is difficult to know the sincerity of any true service problems and give Goettl any credit for honesty. We are largely disappointed and disillusioned with Goettl. Service contract renewal in doubt.

Roger came out on Thanksgiving Day to fix our unit. Turns out, our home builder completely shorted us on the amount of blown-in attic insulation (which you think a home inspector would have caught) and also our unit is too small for our house which is 4 years old. Roger took the time to explain all of this to us in detail and got our unit up and running. Thank you Roger!

Darean serviced our drain line blockage. His professionalism and knowledge for being so young was incredible. This has been one of our best experiences working with a plumber. He was methodical, clean, (like really clean!), and very determined to go above and beyond. I don't leave reviews often but this experience was worthy of a 5 star review. Highly recommend Darean.
