Why won’t my heater turn on? 4 Most Common Heater Repair Issues

If your heater isn’t responding to your commands and the temperature outside is steadily dropping, you might be wondering what to do next. There can be many possible causes for your heater failing to respond to the thermostat, and the only way to know for sure what the issue is with your HVAC system is to call an expert from a furnace repair service.

4 Most Common Heater Repair Issues

If you notice one of these top heater repair issues below, it’s time to call in the experts for heating system repair:

1. Issues Unrelated To The HVAC Unit Itself

There are times that heating system failure is due to a simple issue unrelated to the actual heating unit. If your heating unit is connected to the home’s power grid, the circuit breaker can trip. To see if this may be the cause of your heater failing to turn on, find your fuse box and see if the switch that corresponds to your HVAC system is in the OFF position. Check the fuse box for any signs of an electrical short, like a smoky smell or scorch marks along the sides of the control board.

2. Dirt in The Furnace System

Maintaining the HVAC system might seem like an unnecessary task, especially if you don’t use your furnace much. But failing to maintain the system can lead to dirt getting into the key components of the furnace, like the blower motor and the burners. Once these parts of the HVAC system become weighed down with dirt, the entire system has to work harder to push out warm air. Eventually, the overwork and strain on the unit can cause it to shut down and stop responding to the thermostat. At this point, furnace repair from a professional is the only way to get it working again.

3. Pilot Light Problems

If your heater is gas powered, the furnace’s pilot light may be out.  Many furnaces have a gas reset valve that you can use to try and test the pilot light. Shut the gas off and wait five minutes before turning it back on and trying to start the unit again. If the furnace still does not turn on, there’s a good chance the flame that powers the heater has gone out.

4. Blower Motor Issues

The blower motor is the part of the system that pushes the heated air out and into the ductwork so it can be distributed through the house. When the blower motor gets clogged or shuts down, the thermostat may still respond to your commands and you may hear the unit switch on, but the home won’t get any warmer. If you have a newer unit, it may have a light to indicate whether the blower motor is working properly. If this light is glowing red, there is an issue that you should call an HVAC professional to investigate.

If you suspect that you’re experiencing one of these issues with your HVAC unit, don’t hesitate. Contact Sheldon’s Heating & Air Conditioning at (877) 411-9888 to get affordable furnace repair any time of night or day.

Prolong the Life of Your HVAC System with HVAC Rejuvenation Services

HVAC systems are vital to maintaining a comfortable home, and therefore, are one of the more expensive appliances in a home. Since this is such an important investment, you want to be able to get the most out of it before you have to replace it. Our HVAC rejuvenation services allow homeowners to give their HVAC system a second chance by strategically addressing issues that can prolong the life of your heating and cooling equipment.

Prolong HVAC System Life with Electrical Rejuvenation

HVAC electrical issues are concerning, but certainly not reversible. While these components are critical to the system’s performance, addressing multiple electrical concerns at once can revitalize the system and add years to its lifespan. That’s exactly what our team of HVAC experts as part of our electrical rejuvenation package.

The services we provide as part of our electrical rejuvenation package can address common issues with the following HVAC components:

  • Hot surface igniter
  • Flame sensor
  • Transformer
  • Face electrical absorption system
  • Primary circuit board
  • Air distribution kit
  • Inducer fan motor
  • Pressure switch

Understand When to Maintain, Repair, Rejuvenate, or Replace

The key to prolonging the life of your HVAC system is to know how to manage it throughout the different phases of its life. A newer system doesn’t take a whole lot of maintenance, but it can’t be ignored. Older systems can experience more issues, but it’s important to know the limit where it begins to make more sense to replace an older system rather than put more money into it.


Yearly and bi-annual maintenance are necessary for all HVAC systems. With such a complex mechanism and one that runs constantly for months at a time, many small issues can arise that require routine maintenance. Something as simple as dirt could gunk up your system and develop into a serious issue.

Regular maintenance ensures that your system is running at its best. It also prevents minor concerns and red flags from becoming system malfunctions. Regularly investing in your system with a bi-annual maintenance plan is a key factor in maximizing your HVAC system’s lifespan.


Watch for certain signs that your system could need repairs. If your AC is cutting short or running continually, there could be an issue with your thermostat or another AC component. Unusual sounds and smells can also be a sign that your system may have an issue.

Remember, repairs are quick solutions to immediate problems. They will likely return your system to its original performance before the issue, but they won’t improve your system’s performance.


If you’re looking to revamp an older air conditioner’s performance, an electrical rejuvenation is exactly what you need. Maintenance visits won’t focus on the more in-depth servicing that is included with an electrical rejuvenation package.

Rather than just relying on constant repairs, give your older system a kickstart to prolong its life, improve performance, and increase energy efficiency as a result.


Once your AC reaches 10 years old, it’s likely past its prime. Another sign that your air conditioner needs to be replaced is if it requires regular repairs to keep functioning. If any repair is more costly than a new system, it’s best to invest in the future of your home comfort, rather than an aging system.

Upgrading your system is another key factor to consider when choosing whether or not to replace your current air conditioner. If you’re looking at your energy bill and could benefit from a more modern and efficient system, work with a local Riverside HVAC dealer like Sheldon’s to choose the system that’s right for your home.

Four Major Signs Your HVAC System Needs a Little TLC

Your HVAC system is just like your dog or your newborn baby. You might not speak the same language but it DOES communicate with you. When your air conditioner, heating system, or ducts need attention, there are signs you can look (or listen, or smell) for. Read on to find out what they are.

How to Tell if Your HVAC System Needs Repair

Look for these four tell-tale red flags to know when it’s time to make a change or make a call to an expert HVAC technician.

1. Unusual Noises

Is your HVAC system making noises? You might hear knocking, dripping, creaking, screeching, or a constant cycling of your system powering on and off again and again. These sounds are your system talking to you. Here are a few things you can tell about your system by the sound it makes:

  • Rattles, thumps, or knocks:
    Your motor or a system component is loose or malfunctioning. This could be minor and fixable or more serious and it’s important to call an HVAC expert to determine what’s going on.
  • Tapping or clacking:
    You might have a foreign object stuck inside the blades of your blower. This is likely not critical. Observe your outdoor unit or venture into your attic, basement, or other areas of your house to determine where the noise is loudest or clearest. Call us to come clear the issue.
  • Squeals, screeches, or high pitched whistles:
    You probably have a deteriorating belt which isn’t usually expensive BUT should be repaired before it snaps. If the belt snaps, your system will stop working. You may also need to have your system motor lubricated which CAN be done DIY with the right materials – household oils and WD40 aren’t the right choices for these components – or you can call us for help.
  • Constant turning on and off:
    If you constantly hear your system powering on and off or the airflow is inconsistent, your system is cycling irregularly which requires diagnosis and repair from an expert.

2. Unusual Smells

Just like with your car or your kids, different smells indicate different situations that could need your attention. If you’re experiencing an odor that’s musty, dusty, or “old” smelling, you probably need to replace a filter or have your ducts cleaned. If the smell is burnt, oily, or smoky it could be more serious and probably requires attention.

More importantly, if your home employs natural gas and you smell a sulfuric or egg-like smell, turn the system off and contact a professional right away – you may have a gas leak. If your filter is fresh and you’re experiencing an odor, you’ll likely need an expert to come out and take care of the issue.

3. Temperature Ghosts

Do you ever walk through your home and encounter a hot or cold spot that isn’t conditioned to the same temperature as the rest of the room or house? Sometimes this is explainable – it’s warmer by a sunny window or cooler in a dank basement.

However, if you feel like the patchy quality of your home comfort is not explainable, it’s not REALLY ghosts – it’s inconsistent heating and cooling from an HVAC system that needs your love and care. Your system is trying to tell you that it needs your support – this could require maintenance to the system itself, weather-proofing or insulation for your home, or a change in ventilation.

4. Rising Bills

So you received your electric bill this month and nearly had a heart attack. That could be because of a usual seasonal shift in usage or because your teenager had to charge 8 devices at once in constant rotation. If you’ve cleared the usual suspects, your system may be laboring for some reason.

You might be putting extra pressure on your unit by leaving windows open, coming in and out too much, or by operating with a heavily soiled filter that needed to be replaced three months ago. You may also have a duct leak that’s sapping all of the conditioned air and causing your system to work twice as hard to keep up. Whatever the issue, routine maintenance can prevent these costly surprises and a quick call to us can get you back in working order before your next billing cycle puts you in debt.
