Repair vs. Replacement: Making the Right Choice
Homeowners often wonder whether it’s smarter to repair or replace an older gas furnace. Here’s a simple rule of thumb:
Repair if your unit is under 10 years old and the repair cost is less than 40% of replacement.

Frequently Asked Questions
How do I find an HVAC repair contractor near me?
Once you’ve decided what kind of heating and cooling unit you want to install in your home, you can begin looking for a reliable HVAC installer in your area. Start by asking family and friends if they have any contractor recommendations. You can also check resources like the Better Business Bureau, along with online reviews and ratings for HVAC installers near you.
Modernize offers homeowner reviews, BBB ratings, and Google ratings for all of our contractors so you can get a clear picture before making a hiring decision.
What are some options for local HVAC repair and service?
When you need air conditioning repair or replacement, you can often replace your current unit with a similar heating, ventilation, and air conditioning (HVAC) system. Depending on the climate in your area, you can choose the type of HVAC installation that works best for your home.
In regions with very cold winters, you may need a high-AFUE-rated furnace for heating and a large central air conditioner (up to 5 tons) for cooling. In milder climates, a heat pump may be enough to regulate your home’s temperature, or you might consider a ductless AC system instead of installing a full HVAC system.
Many homeowners choose a furnace and central AC unit that uses ductwork to circulate heated and cooled air. However, heat pumps and ductless mini-splits are also effective options for managing indoor comfort year-round.
How much does HVAC replacement cost near me?
HVAC replacement costs near you can range from $6,224 to $11,434. This includes installation of a new central AC unit and gas furnace combo, along with labor. If you also need to replace the ductwork, expect to add around $2,100 for a single-story, 2,000-square-foot home.
What should I ask a local HVAC contractor when hiring?
How long have you been in business?
How much experience do you have with my type of HVAC system?
What’s your cost estimate for installing my new HVAC unit?
Can you provide a list of references?
Can you show proof of insurance, including your insurance company name, policy number, and coverage limits?
Who will handle the warranty details and responsibilities?
Can I get a fixed price in writing before signing a contract?
What should I do before starting an HVAC installation project?

Reconfirm your initial quote.

Any approved order changes
