What are some signs that my furnace might need to be repaired?

Furnace repairs must be done right away if you want to keep the appliance from experiencing additional harm. But how can you spot a problem? There are, in fact, a ton of common signs you may watch out for that might indicate a problem with your furnace, including: 

·  The furnace isn’t warming your house up enough.

·  The temperature in some areas of your home is noticeably cooler or warmer than in others.

·  Strange sounds include shrieking, rattling, and slamming coming from the furnace.

·  The furnace’s frequent on/off cycles interfere with the heating cycle.

·  Despite a reduction in consumption, heating costs have shot up significantly.

·  Instead of a steady blue flame, the pilot light is yellow or flickering.

·  The furnace is releasing smells that are peculiar or persistent, like burning smells.

·  Rather than heating the air in your home, your furnace is pumping cool air through it.

How long does it take to repair a furnace? 

Depending on the kind of furnace, the amount of the issue, the type of repair needed, and the accessibility of new components, the time required to fix your heating system can vary greatly. A furnace repair may typically be finished in a few hours, although more complicated problems might take longer. The following variables may impact the turnaround time for repairs:

·  Type of Issue: Simple problems like a broken thermostat or a blocked filter may frequently be fixed quickly. In contrast, significant problems could take more time and work to fix, like a fractured heat exchanger or a broken blower motor.

·  Accessibility: Reassembling and disassembling a furnace may take more time if some parts are more challenging to get to by our technicians.

·  Part availability: The time it takes to receive new components may differ if the repair calls for them. Common furnace types may have readily available parts, whereas older or less popular versions may take longer to track down spare parts.

·  HVAC experience: A knowledgeable and professional HVAC expert will probably be able to diagnose and fix the furnace more quickly, which could cut down on the amount of time it takes to fix it compared to someone who doesn’t understand how this type of system functions.

·  The furnace’s level of complexity: Contemporary appliances or high-efficiency furnaces may have more intricate characteristics and parts that call for professional expertise as well as a longer time to fix.

·  Scheduling service calls: The length of the repair process may also be impacted by technician availability. Getting a technician to your location may take longer, depending on who you choose to partner with.

·  Emergency repairs: In comparison to routine, regularly scheduled maintenance or non-urgent repairs, emergency repairs may be given higher priority and finished more quickly, particularly during periods of bad weather.

Given these factors, it’s essential to speak with a certified HVAC professional for a precise quote based on the problem with your furnace. They can evaluate the condition, offer a time estimate, and talk with you about the repair process.

Don’t hesitate to reach out to the team at Mr. Furnace Heating and Air Conditioning to schedule a repair appointment with us and to get a more accurate time frame for your circumstances.

Why does my furnace need a repair so often?

There may be a number of underlying causes if repairs to your furnace are necessary frequently. You must take care of these problems if you want your furnace to run effectively and consistently. The following are typical causes of furnace repairs:

·  Lack of maintenance: Skipping out on routine maintenance tasks like cleaning, filter replacement, and system examinations can result in greater deterioration and shorten the life and dependability of your furnace.

·  Age of the furnace: Older furnaces may need repairs more often and are more likely to break down.

·  Low-quality or worn parts: Your furnace is more prone to break down if its parts are poor quality or worn out. Durability and lifespan depend on high-quality parts and materials.

·  Improper sizing: A furnace that isn’t the right size will cycle too much, work too hard, and degrade too quickly. It’s essential to make sure your furnace is the right size for your house.

If your home’s furnace is breaking down frequently, it may be due to one of the reasons listed above and should be examined by a professional HVAC technician as soon as possible. Our team of certified HVAC technicians is available 24/7/365 days a year, including after-hours, weekends, and holidays, at no extra cost!

In the event that your furnace is at the end of its useful lifespan, we’ll set you up for an at-home consultation with one of our home comfort advisors, who can help you choose a new heating system for your home that’s within your budget. We’ll also give you more information about our fantastic seasonal discounts and flexible financing options that can help you save big on your new equipment, along with a free, non-obligatory new system purchase quote!

Why is my furnace not turning on?

There are a few potential causes for your furnace’s possible inability to start. Here are some typical problems to look for:

·  Thermostat setting: Check your thermostat settings to make sure it is in the “heat” or “auto” mode and adjust it to the appropriate temperature. In certain cases, a straightforward thermostat modification can fix the problem.

·  Dead batteries: Next, check if your thermostat utilizes batteries to see if they are dead or low on power. After replacing the old batteries with new ones, see if your thermostat is able to turn on your furnace. If not, you’ll need to contact a professional repair technician. 

·  Circuit breaker or fuse: In the electrical control panel, look for the circuit breaker or fuse for your furnace. Restart the breaker or have a technician swap out the fuse if it has tripped or blown. Don’t try this on your own if you are not a qualified technician or electrician, as it can be hazardous.

·  Ignition or pilot light problems: Check to see if the pilot light is on in gas furnaces. If not, have a technician relight it according to the manufacturer’s directions. An electronic ignition system may be present in newer furnaces; in this instance, a qualified technician may be required to identify the problem and fix it.

·  Unclean air filter: A dirty air filter may prevent airflow, forcing the furnace to turn off for safety. If the air filter is clogged, have a technician replace it.

·  Clogged vents: Check to see if any vents or registers are blocked and that they are all open. Vent obstructions can cause overheating, which will lead to a system shutdown.

·  Problems with pressure switches: Pressure switches on contemporary high-efficiency furnaces provide a secure operation. The furnace may not turn on if these switches are malfunctioning.

·  Gas supply: Verify that the furnace’s gas supply is turned on. The furnace won’t start.

·  Safety feature: Furnaces are equipped with safety features that can shut them down in the event of problems like overheating or gas leakage. If these safety features are activated, it can be a sign that there is an issue that requires expert assistance.

If you’ve examined these straightforward problems and your furnace still won’t come on, it’s a good idea to call a licensed HVAC professional to identify and fix the issue. It’s advisable to leave complex problems to professionals when working with furnaces because your safety is of the utmost importance.

Is furnace repair covered by homeowners’ insurance?

The majority of the time, furnace repairs are not covered by regular homeowners’ insurance. Homeowners insurance often includes liability protection for injuries sustained on your property in addition to coverage against particular perils like burglary, vandalism, fire, and catastrophic weather events. Typically, ordinary homeowner insurance policies do not cover general deterioration, maintenance, or repairs of house equipment like furnaces.

Repairs or replacements resulting from flaws in the components or the craftsmanship of your furnace may be covered if they remain protected by the manufacturer’s warranty. So, we suggest looking over your furnace warranty agreement to see if it is still valid.
