If your furnace is aging, unreliable, or costing too much to operate, a new high-efficiency system can transform your home’s comfort while cutting energy costs.

The White Glove Guys handle every aspect of furnace replacement—from helping you choose the right system and capacity for your home, to precision installation that ensures peak performance. We offer all major brands and flexible financing options, so you get the best system for your needs and budget.

Signs You Need Replacement

Is Your Furnace Due for Replacement?

These signs indicate your furnace may be approaching the end of its useful life.

Age 15+ Years

Most furnaces last 15-20 years with proper maintenance. If yours is in that range, it's operating well below the efficiency of modern systems, costing you more every month.

Rising Repair Costs

If you're spending increasingly more on repairs each year, those costs add up. When a single repair exceeds 50% of replacement cost, a new system is the smarter investment.

Excessive Noise

Banging, popping, rattling, and squealing are signs of worn components throughout the system. A new furnace operates quietly and reliably.

Uneven Heating

Cold spots and rooms that won't warm up indicate your furnace can no longer distribute heat effectively. A properly sized new system delivers consistent warmth throughout your home.

Repair or Replace? Making the Right Decision

  • Furnace is less than 12-15 years old
  • Repair costs less than 50% of replacement
  • System has been regularly maintained
  • This is your first major repair
  • Heat exchanger is in good condition

Replace Your Furnace

Consider replacement when you notice:

  • Furnace is 15-20+ years old
  • Frequent, costly repairs adding up
  • Energy bills rising significantly
  • Cracked heat exchanger or safety concerns
  • Uneven heating or excessive noise

I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation

I recently had some plumbing work performed by Sam and Matt who are two team members from ASI and I felt that a comment on their service was warranted. This was a large job. They thoroughly inspected the plumbing and photographed the sections of cast iron pipe that were almost rusted through. Sewer pipes leaking under the house would be a pretty major problem. The whole project took about a week. Sam and Matt were here working hard every single day. I am completely satisfied with the work done, and I can’t say enough about these two individuals. They were polite, punctual, very thorough, and definitely knew their craft. I went under the house to check the installation and it was flawless. One aspect of their performance deserved a special mention. Although crawling around in the dirt under the house was extremely messy, they wore overalls and shoe covers when they entered the house. “White glove” service indeed. If you’re looking for plumbers who excel at their trade, definitely give ASI a call.

FAQ

Furnace Replacement Questions Answered

Furnace replacement costs vary based on system size, efficiency rating, and installation requirements. We provide free in-home estimates with transparent pricing. Financing is available to make a new system affordable for any budget.

Most standard furnace replacements are completed in one day. More complex installations may take longer. We’ll provide a clear timeline during your consultation.

For San Diego’s climate, a furnace with 80-95% AFUE is common. Higher efficiency costs more upfront but saves more on energy bills over time. We’ll help you find the sweet spot for your budget and usage.

Not always. We’ll inspect your existing ductwork during the consultation. If it’s in good condition and properly sized, we can connect your new furnace to the existing ducts. If there are significant leaks or sizing issues, we’ll recommend repairs or replacement.

Watch for a furnace that is 15 or more years old, rising heating bills, uneven heating between rooms, frequent repairs, strange noises, or a yellow rather than blue burner flame. A cracked heat exchanger or repeated cycling are also strong signs replacement is due. If you notice any of these, have it inspected before the unit fails on a cold night.

Yes. Older furnaces can develop cracked heat exchangers that allow carbon monoxide to enter your home. Newer furnaces include improved safety controls, sealed combustion on high-efficiency models, and better venting. Every furnace we install is set up to current code and safety standards, and we recommend a working carbon monoxide detector near sleeping areas.

Yes. We offer flexible financing so a furnace replacement fits your monthly budget rather than requiring a large upfront payment. During your free in-home estimate we can review the available options and monthly terms. Our pricing is upfront and flat-rate, so you will know the full cost before we begin.
