Protect Your Family with Annual Furnace Maintenance

Your furnace does more than keep your home warm—it keeps your family safe. A poorly maintained furnace can develop carbon monoxide leaks, electrical hazards, and gas issues that put your household at risk. Annual maintenance is the single best thing you can do to ensure safe, reliable, and efficient heating all winter long.

ASI’s comprehensive furnace tune-up goes beyond a basic filter change. The White Glove Guys perform a multi-point safety inspection, clean critical components, test all safety controls, and verify efficient operation. We catch small problems before they become expensive repairs or dangerous failures.

Why It Matters

What Happens When You Skip Furnace Maintenance

Skipping your annual tune-up leads to these preventable problems.

Safety Risks

An unmaintained furnace can develop cracked heat exchangers that leak carbon monoxide, a colorless and odorless gas. Annual inspections are your first line of defense against this deadly hazard.

Higher Energy Bills

Dirty burners, clogged filters, and worn components force your furnace to work harder. Annual tune-ups can improve efficiency by 10-15%, saving you money every month.

Unexpected Breakdowns

Most furnace failures are preventable. A tune-up catches worn parts, loose connections, and developing issues before they leave you without heat on the coldest night.

Shortened Lifespan

A furnace that receives annual maintenance lasts significantly longer than one that doesn't. Protect your investment with regular professional care.

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.

A furnace tune-up is a low-cost flat-rate service, and we give you the exact price before we start, with no extra fees for nights or weekends. It is one of the most affordable ways to protect your home, since the cost of a tune-up is far less than an emergency repair or premature replacement. Maintenance plan members receive their annual visit at a reduced rate.
