What To Consider When Replacing an HVAC System

Published by Luke Weiden

If you’re considering replacing your HVAC system, you’ve come to the right place. At Deljo Heating & Cooling, we’ve helped homeowners make smart HVAC decisions since 1922. Let’s dive into everything you need to know about replacing your HVAC system.

When to Replace Your HVAC System

Should you replace your entire system? Or simply schedule HVAC repairs? Factors to consider when making this decision include:

  1. Age: Most HVAC systems last 15-20 years. If yours is approaching this age, replacement might be more cost-effective than repairs.
  2. Frequent repairs: If you’re on a first-name basis with your HVAC repair technician, it might be time for an upgrade.
  3. Rising energy bills: An inefficient system works harder, driving up your energy costs.
  4. Inconsistent temperatures: If some rooms are too hot while others are too cold, you may need a more powerful system.
  5. Strange noises or odors: Unusual sounds or smells often indicate serious issues.
  6. Poor air quality: Address allergies or high indoor humidity levels with an HVAC system upgrade.

Factors to Consider When Choosing a New System

Determined to replace your system with a better one? Here’s what you should keep in mind:

  1. System type: Consider whether a split system, packaged unit, or ductless mini-split best suits your home.
  2. Energy efficiency: Look for ENERGY STAR-certified units with high SEER and AFUE ratings.
  3. Size: An improperly sized system can lead to discomfort and high energy bills.
  4. Zoning: Consider a zoned system for control over the temperature of individual rooms.
  5. Smart features: Many modern HVAC systems offer Wi-Fi connectivity and smart home integration.
  6. Indoor air quality add-ons: Consider adding air purifiers or humidifiers for optimal comfort.
  7. Budget: Consider both upfront costs and long-term energy savings.
  8. Warranty: A good warranty will protect your investment and save you money.

How Long Does It Take to Replace an HVAC System?

A typical HVAC replacement timeline looks like this:

  1. Removal of old system: 2-3 hours
  2. Installation of new system: 4-8 hours
  3. Testing and adjustments: 1-2 hours

Most HVAC replacements are completed in a single day.  However, more complex installations take 2-3 days.

Do You Need a Permit for HVAC Replacement?

Permits are typically required for full HVAC replacements. In Chicago and most surrounding suburbs, you’ll need a permit for HVAC replacement. Here’s what you need to know:

  1. Permit requirements vary by location. We’re familiar with local codes and will handle the permitting process for you.
  2. Permits ensure your installation meets safety and efficiency standards.
  3. Skipping the permit can lead to fines and complications when selling your home.
  4. As licensed professionals, we ensure all our work is up to code and properly permitted.
