What factors affect the cost of a furnace install?

The price of a furnace install varies based on three main factors: the system purchased, the need for home renovations and the contractor you hire to perform the work.

  • Furnace cost: Furnace models come in a variety of sizes (measured in BTUs) and efficiency ratings (measured by AFUE). Not to mention all the experienced brand names out there to choose from! The good news: Aiello helps you find the best furnace brand and model by only showing you furnaces that meet the needs of your home, family and budget.
  • Home renovations: Modifying gas or oil lines, oil tanks, ducts and electrical systems in an existing home may be necessary to accommodate your new furnace. Aiello has in-house pros for all of the above, which makes every furnace install that much easier!
  • The contractor you hire: Pricing for furnace installations vary from contractor to contractor. These rates are based on a contractor's experience, skill level, training and other factors. An improper furnace install can increase your energy bills, decrease the lifespan of your system and lead to frequent breakdowns. That's why going with a company you know will get the job done right is always the best choice.

Our 5-star furnace replacement process

  1. We perform a free in-home estimate

    At Aiello, we want every customer to feel confident when they purchase a new system. That's why we send one of our expert comfort specialists to your home to perform a thorough in-home walkthrough and load calculation, completely free of charge. For additional peace of mind, we send every customer a bio and picture of their comfort specialist prior to their arrival and an easy link to follow them on their way to your home.

  2. We share a variety of replacement options

    Once the in-home assessment is complete, the next step is to share new system options with our customers. Aiello installs hundreds of different types of systems every year and has a larger selection of brands and models than any other contractor in Connecticut. More options means more chances to identify a system that meets the comfort, convenience and budget needs of our customers.

  3. We prepare for a successful furnace installation

    After a customer has selected the perfect system, we'll then look for additional ways to save them money on the install. This includes helping you apply for Energy Star rebates, locate specific tax credits and set up financing upon request. Back at headquarters, we'll order the new system from the manufacturer, and our professional installation team will prepare the strategy for installation day.

  4. We give you a 5-star installation experience

    By the time installation day arrives, a huge amount of planning and preparation has already taken place. For our customers, it means better installations completed in a faster time frame with no hassles or confusion. In addition to that, we go above and beyond to protect your property by wearing shoe covers while in your home, laying down drop cloths and completing a thorough clean up to ensure we leave your home as clean or cleaner than how we found it.

Your satisfaction means the world to us

Our goal is to give every Aiello customer a 5-star experience. That's why we ask if we delivered 5-star service at the end of every job. If not, we'll do everything we can to correct that issue before we leave.

Earning Connecticut’s Trust, One 5‑Star Visit at a Time

“Everything they did was efficient and professional...”

“We had our furnace replaced by Aiello. The entire experience was outstanding, from dealing with the sales representative to the crew that came and did the work. Everything they did was efficient and professional. The men were pleasant and polite at all times. They left the basement cleaner than when they arrived. We are very pleased with the system, and everything was explained to us very patiently. In all, we are very pleased we called Aiello.”
