Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.

Professional & Friendly
Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.

Furnace Installation FAQs
What does the furnace installation process include?
We will take out your old furnace. Then, we will install the new unit. We will connect it to gas lines or electrical systems. We will also adjust the ductwork and do a full safety check.
How long does a typical furnace installation take?
Most technicians complete furnace installations in one day, depending on the complexity of the job.
Can I save by replacing the furnace instead of installing from scratch?
Yes, if you have ductwork and gas lines already, replacing the furnace is usually quicker and cheaper.
When is the best time to install a furnace?
Fall is ideal, before peak heating season. However, our team installs furnaces year-round, including same-day service in emergencies.
Should I repair my furnace or opt for a new installation?
If your furnace is more than 15 years old, it may need many repairs. If it is also increasing your energy bills, consider getting a new one. A new furnace could be a better choice in the long run.
