Replace AC and furnace at the same time?

May 31, 2019

Sometimes, all the home repairs come at once. Although it can be a headache to deal with multiple repairs – especially in Los Angeles – there are some advantages. For example, you can look at solutions that otherwise wouldn’t have been feasible. So when it comes to HVAC sometimes customers ask, is it a good idea to replace your AC and furnace at the same time?

The answer is: it depends. There are pros and cons to replacing the two major components of your HVAC system. As a Carrier Factory Authorized Dealer serving LA for over 70 years, we are well-versed in this predicament!

Advantages to replacing AC and furnace together

Your furnace and your air conditioner work together to heat and cool your home. Did you know: even during the summer, your furnace is working? That’s because your furnace contains the blower fan that helps move air through your home. The evaporator coil for your air conditioner is the indoor portion that makes that air cold. In short, your furnace and your AC work together and not independently.

There are several advantages if you want to replace your AC and furnace at the same time:

  • Reduced downtime – by doing both installs at once, you can limit how long your heating and cooling system will be inoperable.
  • Improved system efficiency – since air conditioners rely on the blower in a furnace to move air, the efficiency of the fan matters greatly to the efficiency of your air conditioning system. So, when you replace both your AC and your furnace you’ll realize greater efficiency gains than if you replaced just one.
  • More options – If you decide to replace all the components in your HVAC system, you can consider other system types. For example, a heat pump system or a ductless system may be a good option for your home. These systems offer cooling and heating from a single device. In this case, you’d be replacing two pieces of equipment with just one.
  • Save with promotions and rebates – Most deals that are available to homeowners are limited time offers. That includes lucrative HVAC rebates from local utility companies. Rebates don’t always make a comeback, so when they are available to you its a great time to take advantage. Usually, incentives will be offered for air conditioners and furnaces separately. So if you replace your AC and furnace at the same time, you can double dip!

Disadvantages to replacing your AC and furnace simultaneously

Although there are a lot of benefits to replacing these two systems together, there are some drawbacks.

The obvious first challenge relates to the total cost of the investment. There are lots of ways to save on a new HVAC system, but there’s no getting around this one. It will be a pricey endeavor! The silver lining is that when you replace both systems at the same time, you’ll save on the total cost of the installation. Replacing just a furnace is somewhat expensive, but adding a furnace replacement to an AC replacement is just a few thousands dollars.

Another hang-up to replacing your AC and furnace at the same time would be if you plan to sell soon. HVAC replacements are known as invisible improvements. A brand new heating and cooling system just isn’t as sexy as a new kitchen or a resort-style pool. When it comes to selling your home, a new heating and cooling system will be a bonus to buyers – but likely won’t improve your home’s value. So, if you think you’ll be selling in the next few years, it may make sense to only replace one piece of equipment or the other.

When does it make sense to replace my AC and furnace at the same time?

There are a couple of scenarios that would make us recommend replacing both systems simultaneous.

  1. Replacing Your Furnace – Furnaces can last as long as 30 years. So, if you’re already looking at installing a new furnace for your home, you might as well look at your air conditioner at the same time. The newer, more efficient HVAC equipment available often combines the heating and cooling systems.
  2. Retirement – If you’re nearing retirement age, now is the time to take care of these more expensive home repairs. Once you are on a fixed income, it can be more difficult to arrange for big home projects.
  3. Complex Installation – Homes with tight crawl spaces or difficult-to-access outdoor spaces (such as condos in downtown LA) may benefit from replacing all their systems at the same time.

Called about an issue with our HVAC and they were able to send a tech the next day. David M was super thorough and took helpful pictures and videos to describe the issues we were having, since our unit is on the roof. When we decided that we needed to escalate to potentially replacing our unit, supervisor Fabio was able to come out within half an hour and provide us with our options for replacement. He was super accommodating and was even able to fit us into his schedule for the following week! Great experience all around.

June14, 2024Armando performed the annual service visit on my A/C unit. Great experience for us. He was on time, knowledgeable about the unit and as well as doing the service, he reviewed pics he took of the attic, duct work, etc. and made suggestions on how to improve the unit's longevity and performance.Professional, pleasant and thorough service technician. Shawn was excellent!I thought it very cool that I was texted a link to a website that allowed me to see the technicians vehicle distance on the map from my house so that I knew exactly where he was and when he'd be at my house.

The whole experience of having my HVAC system serviced has been more pleasant than I could have ever imagined. Brody Pennell offers a level of service that is increasingly hard to find in the modern marketplace. My tech, Richie Salazar, went above and beyond — not just providing the standard filter change, but running a complete diagnostic of the system and hand cleaning the whole unit. Made me wish I had purchased the unit from Brody Pennell in the first place. As a homeowner, moving forward, I wont work with another SoCal HVAC contractor. Thanks to the whole team.

Ashton and Juan Molina were great in explaining what needed to be fixed and what options I had. My AC unit was not blowing cold air, and the machine was over heating - the unit was at the end of its life expectancy and suggested it be replaced, as even repairing it would only be a short term fix, which he showed me what temperature it would still be at if we did replace. Everything was communicative and quick process. Would recommend. Thank you both!
