How Do You Fix a Heater That Won't Heat?

Every heater is unique, which is why the best way to troubleshoot a broken heater is to first call a professional. From the thermostat to the ignition system, various components can malfunction, making it difficult (and even dangerous) to complete repairs without help from a professional.

What Would Cause a Heater To Stop Working?

Several factors can cause a heater to stop working, including: Thermostat malfunctions: Issues with the thermostat's settings, wiring, or internal components can prevent the heater from turning on or maintaining desired temperatures. Ignition problems: Problems with the pilot light, electronic ignition, or gas supply can hinder the heater's ability to start. Ductwork obstructions or leaks: Blockages or gaps in the ductwork can reduce airflow and heating efficiency. Wiring and electrical issues: Faulty wiring or electrical components can cause the heater to malfunction and pose safety hazards. Contact your local Aire Serv as soon as possible to diagnose and fix the issue.

What Is the Average Lifespan of a Heating System?

The lifespan of a heating system varies depending on several factors, including the type of heater, maintenance practices, and operating conditions. Generally, you can expect the following average lifespans: Furnaces: 15-20 years Boilers: 20-30 years Heat pumps: 15-20 years However, every type of heating system is different. Regular maintenance, such as annual inspections and tune-ups, can significantly extend the life of your heating system. Prolong the life of your heater by signing up for the Advantage Plan with twice-yearly tune-ups and a 15% discount on all HVAC services.

Should I Repair or Replace My Heater?

If your heating system is less than 15 years old, a repair may be the best option, depending on the problem. If your heater is over 15 years old, a better long-term option might be to replace it. The answer will ultimately depend on what’s causing the problem. While some issues are easier to fix, others can be more complex, which might make replacing your heating system for a different gas or electric one more practical.

How Do You Diagnose a Home Heater Problem?

While a final and definitive diagnosis should always be performed by an experienced and licensed HVAC professional, here are some common indicators that might signal an issue with your heater: Unusual noises: Clicking, banging, or screeching sounds can indicate component problems. Insufficient heat: If your home isn't warming up adequately, there might be a blockage, airflow issue, or component failure. Strange odors: Burning smells can be a sign of electrical problems or component failure. Pilot light issues: Difficulty igniting or keeping the pilot light lit can point to gas supply or ignition problems. If you notice any of these signs, contact your local Aire Serv service professional for inspection and repair.

Can Electric Heaters Be Repaired?

A five-star review from Dave. S via Google: “Aire Serv, of Newark DE, replaced my heater & AC last fall, and it was such a great experience that I recommended them to replace my mother’s air conditioner this summer. As usual, they offered competitive pricing, timely installation, friendly and competent staff. I couldn’t ask for more, and I’ll continue to recommend them.”
