As the cold settles in, a malfunctioning heating system quickly turns a cozy home into a frigid place to get through the night. Although a broken furnace, boiler, or HVAC system is never convenient, there are some things you can do to turn a cozy haven into a frigid battleground.

Read on to learn what those are and don’t hesitate to contact the West Milford heating experts at Mark Lindsay and Son Plumbing & Heating if you have questions or need to schedule service!

You’re Experiencing Uneven Heating

When you’re dealing with uneven heating, some rooms in your home or office may be roasting and other areas cold. The issue can make it uncomfortable to sleep or get through the day.

Problem: Uneven heating could be a sign of air flow issues, a problem with your ductwork, dirty air filters, or a broken heating system.

Solutions: The first step is checking and cleaning vents to ensure unobstructed airflow. Next, you should try replacing or cleaning your air filters regularly. Scheduling regular, ongoing heating maintenance for your furnace, boiler, or other HVAC unit will also help with uneven heating and keeping your system working reliably.

You Have No Heat or Insufficient Heat

Are you waking up to no heat or insufficient heat? You need help right away to stay warm and safe this summer.

Problem: It’s the nightmare scenario – your heating system refusing to produce heat or not reaching the desired temperature. No heat on a cold day isn’t just uncomfortable, it also isn’t safe for your health or your home and could lead to frozen pipes that burst. The cause of insufficient heat could range from thermostat malfunctions to issues with the pilot light or igniter.

Solution: Make sure your thermostat is set to the desired temperature and check for a blown fuse or tripped circuit breaker in the electrical panel. For gas furnaces, verify that the pilot light is still lit, or for newer systems, ensure the electronic igniter is functioning properly.

You Hear Strange Noises

It’s never a good sign when you hear grinding, hissing, clanging, or banging coming from your heating system.

Problem: Your heating system has developed a complete repertoire of unsettling sounds that keeps you up at night, from bangs and clangs to squeaks and groans. Any one of these noises could indicate issues with the blower motor, burners, or other internal components.

Solution: Investigate the source of the noise and see if you can tighten any loose components. It’s more likely you’ll need help from the professionals at Mark Lindsay & Son to come out for a heater repair or comprehensive check to see what’s going on. You may have worn out equipment or need maintenance and lubrication to get things working again.

Your Heat Continuously Cycles On and Off

Are you noticing your heat may go strong for awhile and suddenly stop before it reached the desired temperature? We can help.

Problem: Your heating system seems stuck in a perpetual loop of starting and stopping, leading to increased wear and tear and reduced efficiency.

Solution: The problem could be a dirty air filter and need a simple check and replacement. Next, check to see if your thermostat is working correctly. If nothing is working for you, consult with an HVAC technician right away to diagnose potential issues with the thermostat, flame sensor, or other components.

You Have a Pilot Light or Ignition Problems

Sometimes furnace issues are about a malfunctioning pilot light, which can leave your home feeling cold.

Problem: When you’re dealing with a gas-powered system, you may have issues with the pilot light or ignition that results in a lack of heat production.

Solution: If your pilot light has gone out, follow your heater’s manufacturer’s instructions to relight the flame. You can also try cleaning the pilot assembly and ensure the flame sensor is unobstructed.
If you can’t get it working again, or notice a flame that’s not blue and going strong, contact Mark Lindsay & Son today to inspect and repair the ignition system.

Your Thermostat Is Malfunctioning

Is your thermostat acting strangely and not working the way it should?

Problem: The thermostat is the control center of your heating system, and malfunctions can lead to temperature inconsistencies or complete system failure.

Solution: Start with an easy step by replacing your thermostat batteries (if applicable). Next, look up the manufacturer’s instructions to calibrate the thermostat and ensure accurate temperature readings. You can also consider upgrading to a programmable thermostat for enhanced control and energy efficiency.
