Lack of Maintenance is #1 One Reason Why Furnaces Fail

Neglecting maintenance often results in unexpected furnace breakdowns and wasteful energy usage. Many homeowners can’t recall the last time their furnace was inspected, assuming it was three to five years ago without any real basis of knowledge.

Your furnace may have spent years without inspection — and may still need inspection even if it was installed within the last year.

Why Furnace Maintenance is Important

Routine furnace maintenance is essential, as maintenance can identify potential issues before they become serious problems, reducing the risk of unexpected breakdowns.

Maintenance ensures your furnace works efficiently and properly, which will greatly extend the lifespan of your heating system. Perhaps most importantly, maintenance checks can identify safety hazards such as:

  • Gas leaks.
  • Faulty wiring.
  • Carbon monoxide leaks.

Experienced Technicians for Furnace Repair

After the diagnostics check, our team of skilled technicians will proceed to do the necessary repairs and replacements — all with your approval.

Wear and Tear

Moving parts like belts and bearings naturally wear out, causing overheating or airflow issues. This wear and tear often causes odd noises, a telltale sign your furnace needs some repairs. Other common repairs due to wear and tear include:

  • Igniter or pilot light replacement.
  • Blower motor repairs.
  • Air filter replacement.

Other Furnace Issues

Our expert repair team may also replace heat exchangers, thermostats, and electrical components.

It’s important to note that cracks in the heat exchanger can lead to dangerous carbon monoxide leaks that require prompt emergency repairs; we’ll make sure no such leaks affect your home, leading to long-lasting indoor air quality.

Furnace Replacement & Installation

During inspections, we may find  that— whether due to age, inefficiency, or frequent repairs —replacement is the best option for your furnace, rather than repair.

If that’s the case, our team will recommend the best furnaces from reliable brands based on your home’s heating requirements and your budget.

New Furnace Installation

Before installation, our skilled technicians will safely remove and dispose of the old furnace. Then, we’ll efficiently set up the new unit. We  handle all necessary connections to ensure everything is secure and up to code, including:

  • Ductwork.
  • Gas lines.
  • Electrical.

Our Atlanta Heating & Air Company Reviews

Matt and Cody diagnosed and corrected my heating system problem quickly and efficiently. They were so knowledgeable and explained everything throughout the process. I am very pleased with Andy Lewis Hobson Heating and Air. They are the best!
Very good communications and excellent Service Technician Richard Rushing. He solved our problem in a very professional manner and he’s such a nice guy.
I would like to take this opportunity to share with the public my experience with Andy Lewis/Hobson Heating &Air.
I have dealt with a fair number of companies in this field. I have never had such a pleasurable experience. Their pricing is excellent, but most importantly they back their work. They have the most experienced technicians and service people. What adds to this experience for me is that I relied on them and they did everything that needed to be done and MORE!!! In essence what I am saying is you need not look any further!!!
I recommend them without equivocation.
