Gas heater professionals near you

It's best to service your gas heater once a year, ideally in the fall before you start using it regularly. An annual tune-up can keep it running efficiently, help prevent dangerous carbon monoxide leaks, and catch small issues before they become expensive problems.

Your gas heater typically needs an annual inspection to ensure it’s running safely and efficiently. This service usually includes cleaning the burners, checking the heat exchanger for cracks, and testing all safety controls. A professional will also inspect the ventilation system to prevent any carbon monoxide issues and ensure proper airflow.

There are several factors that might impact the cost of this project, including:

• Type of service: A routine maintenance check-up will typically cost less than a complex repair or a full replacement.

• Heater model and age: The specific make and model of your gas heater can influence the price, as parts for older or less common units may be more expensive and harder to find.

• Replacement parts: If the job requires new components, such as an igniter, a thermostat, or a blower motor, the cost of these parts will be factored into the final price.

• Accessibility: If your heater is located in a hard-to-reach area, like a cramped crawl space or attic, the additional time and effort required can increase labor costs.

• Complexity of the issue: A simple fix will cost less than a problem that requires extensive diagnostic work and a more complicated repair. Emergency or after-hours service calls also usually have higher rates.

The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one.

When looking for heater technician, make sure you complete the following steps:

• Verify their license and insurance: A qualified professional should have an HVAC license and may hold specific gas-fitter certifications. They should also carry general liability insurance. Requirements vary by region, so it’s always a good idea to check local regulations.

• Get several bids: A proper written estimate should detail the costs for labor, any necessary parts, and potential permit fees.

• Read their reviews: Look for reviews that mention punctuality, professionalism, and effective repairs. Red flags for gas heater work include comments about upselling, recurring issues after service, or a lack of communication.

• Look at their portfolios: For installations or major repairs, ask to see photos of past work. Look for neat, secure installations with clean pipework and proper venting, as this indicates attention to safety and detail.

• Find out if they have warranties: Ask if offer a guarantee on their labor. If you’re getting a new unit or parts, there may also be a separate manufacturer's warranty.

• Ask important questions: Before hiring, ask questions like, “Are you licensed to work on gas appliances in this area?” and “What is your experience with my specific model of heater?”

Many HVAC pros can help diagnose and fix common gas heater problems, including:

• Pilot light or ignition problems. The pilot light may refuse to stay lit, or the electronic ignition can fail. This is often due to a dirty or faulty sensor, a draft, or a gas supply problem.

• A malfunctioning thermostat. If your heater won’t turn on or cycles irregularly, the thermostat might not be calibrated correctly or could have a wiring issue.

• Dirty or clogged filters. Restricted airflow from a dirty filter can cause your heater to work harder, overheat, and eventually shut down as a safety measure.

• Strange noises. Rumbling, squealing, or banging sounds can point to various issues, from a dirty burner to a mechanical problem with the blower motor.

• A cracked heat exchanger. This is a serious safety concern, as it can leak carbon monoxide into your home. Key signs include strange odors or a yellow, sooty flame instead of a clear blue one.

Most gas heaters last between 10 and 25 years, depending on the model and how well you maintain it. A tank-style water heater’s lifespan is typically around 10 years, while a furnace can last up to 25. Following a regular maintenance schedule is the best way to help your unit reach its full estimated lifespan.

Whether you should replace or repair your heater depends on its age, condition, and repair costs. If your gas heater is less than 10 years old and the repair is minor, repairing it is usually the more affordable option. However, if the heater is over 10–15 years old, needs frequent repairs, or the repair cost is close to half the price of a new unit, replacement may be the better long-term choice. Replacing an older gas heater can improve energy efficiency, lower utility bills, and provide more reliable heating. Safety issues, such as cracks or carbon monoxide concerns, are strong reasons to replace rather than repair.
