Atlanta Residential Heating Services FAQs

What is the lifespan of a residential furnace?

The average lifespan of a residential furnace is 15 to 20 years, depending on the brand, model, and how well it is maintained. Regular maintenance, including filter changes and annual tune-ups, can help extend the furnace’s longevity and efficiency. We understand how infuriating a dying furnace can be for your home; at ALH, we offer free estimates on furnace replacements to help decide whether your furnace needs a replacement or repair.

Why is furnace maintenance important?

Routine furnace maintenance is essential to ensure your heating system operates efficiently and safely. Regular tune-ups help prevent breakdowns, improve energy efficiency, lower heating costs, and extend the lifespan of your furnace. Additionally, maintenance helps identify potential issues before they turn into costly repairs.

Do you need to service furnaces every year?

Yes, it is recommended to service your furnace annually. An annual inspection and tune-up from ALH ensures that your furnace is running safely and efficiently. This helps improve performance, reduce energy bills, and prevent unexpected malfunctions during colder months.

How often do I need to replace my furnace filter?

The frequency of furnace filter replacement depends on the type of filter and household conditions. In general:

  • Basic fiberglass filters should be replaced every 30–60 days.
  • Pleated filters should be replaced every 60–90 days.
  • HEPA or high-efficiency filters may last 6–12 months but should be checked regularly.
  • If you have pets, allergies, or live in a high-dust area, replacing filters more frequently is advised.

How long does it take to install a furnace?

Furnace installation typically takes 4 to 8 hours, depending on the complexity of the job. If additional ductwork or modifications are needed, installation can take longer. At ALH, our team of professional HVAC technicians can provide a more accurate timeline based on your specific home setup.

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.
