Common Issues

Furnace Problems We Fix Every Day

Our expert technicians have seen it all and can quickly diagnose and repair these common furnace issues.

Furnace Won't Turn On

One of the most common calls we receive is from homeowners whose furnace simply won't start. This can be caused by several issues: a tripped circuit breaker, faulty thermostat, broken ignition system, or pilot light problems. Our technicians will systematically check each component to identify the root cause and get your heat restored quickly. We carry most common parts on our trucks, so many repairs can be completed in a single visit.

Furnace Blowing Cold Air

If your furnace is running but only blowing cold air, you're not getting the comfort you need. This frustrating problem can stem from a malfunctioning pilot light, gas supply issues, dirty flame sensors, or problems with the heat exchanger. Our certified technicians will perform a comprehensive diagnostic to pinpoint the exact issue. In many cases, this can be resolved with a simple cleaning or minor part replacement, getting your warm air flowing again.

Water Leaking Around Furnace

Discovering water pooling around your furnace is concerning and requires immediate attention. High-efficiency furnaces produce condensation as part of normal operation, but leaks can indicate a clogged condensate drain, cracked condensate pump, or issues with the heat exchanger. Water leaks can cause significant damage to your home and may signal a serious safety issue. The White Glove Guys will quickly identify the source of the leak and make the necessary repairs to prevent further damage.

Unusual Noises From Furnace

Your furnace should operate relatively quietly. If you're hearing banging, rattling, screeching, or grinding noises, something is wrong. These sounds can indicate loose components, worn bearings, a failing blower motor, or problems with the ignition system. Ignoring these noises can lead to more serious damage and costly repairs down the line. Our experienced technicians can identify the source of the noise and recommend the appropriate repair to restore quiet, efficient operation.

Insufficient Heat or Uneven Heating

If your furnace is running but your home isn't reaching the temperature set on your thermostat, or if some rooms are warm while others remain cold, you have a heating efficiency problem. This could be caused by dirty air filters, duct leaks, blower motor issues, or an undersized system. Our technicians will evaluate your entire heating system, including ductwork and insulation, to determine why your home isn't heating properly and provide solutions to improve comfort and efficiency.

Repair or Replace?

Making the Right Decision for Your Home

One of the most common questions we hear is: "Should I repair my furnace or replace it?" As a company that's been serving San Diego for over 70 years, we pride ourselves on giving honest recommendations that are in your best interest.

Repair Your Furnace

Consider repair when these factors apply:

  • Furnace is less than 10-12 years old
  • Repair costs less than 50% of replacement
  • System has been well-maintained
  • This is your first major repair
  • System is properly sized for your home
  • Planning to move in the next few years

Replace Your Furnace

Consider replacement when you notice:

  • Furnace is 15+ years old
  • Frequent, costly repairs adding up
  • Energy bills increasing significantly
  • Uneven heating or persistent cold spots
  • Hard-to-find replacement parts
  • Want energy-efficient technology

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

Your Furnace Repair Questions Answered

Most furnace repairs in San Diego fall between $150 and $650, depending on the failed part and the problem. ASI gives you an upfront, flat-rate price before any work begins, so you approve the cost in advance with no hourly surprises and no overtime fees for nights or weekends.

Yes. ASI provides same-day and next-day furnace repair throughout San Diego County. If your heat is out, call us early in the day and we will do everything we can to get a licensed technician to your home before evening.

Watch for weak or uneven heating, short cycling (the furnace turning on and off rapidly), a yellow burner flame instead of blue, banging or rattling noises, a sudden jump in your energy bill, and a thermostat you constantly nudge higher. Any of these means it is time for an inspection.

A good rule of thumb: repair makes sense if your furnace is under 12 to 15 years old and the repair costs less than half the price of a new system. If it is older, breaking down often, or facing a major repair, replacement is usually the smarter long-term investment. ASI will give you honest options either way.

Not always. A malfunctioning furnace can be a safety hazard, especially a cracked heat exchanger, which can leak carbon monoxide into your home. If you smell gas, hear unusual noises, or your carbon monoxide detector sounds, shut the furnace off and call ASI right away.

Yes. ASI technicians service and repair all major furnace brands and models, including gas, electric, and high-efficiency systems. We have kept San Diego homes comfortable since 1952 and stock common replacement parts, so most repairs are finished in a single visit.
