What Are the Signs That Your Furnace Needs to Be Repaired or Replaced?

Harrisburg Furnace Repair & Replacement.

No one wants to be without heating in the cold Pennsylvania winters, so if you spot the signs that you might need a furnace repair, it's best not to delay. By calling in Harrisburg, PA professionals promptly, any repairs could potentially extend the lifespan of your furnace. Waiting too long to get any repairs carried out could mean you end up needing a full furnace replacement sooner than expected due to more extensive damage.

Top Six Signs That Indicate You Need a Furnace Repair or Replacement

A faulty furnace can represent a safety risk, so it's essential to know the signs to look out for. Some of the most common include:

  1. Rising Energy Costs
    If you notice a change in your energy costs with no apparent cause, it could be a sign there's a problem with your furnace. A malfunctioning furnace might have to work much harder to produce the same output, burning more fuel in the process. It may be as simple as a clogged filter, but it could also mean that your furnace needs to be replaced.
  2. Unusual Noises
    Be vigilant for any unusual noises, as this could indicate that your furnace needs to be checked over. You might notice various types of noises, such as knocking, whistling, squeaking, humming, or rattling. The type of noise your furnace makes can help to pinpoint the problem more quickly, so describing the sound and when it occurs to the professional can be very helpful.
  3. Unpleasant Odor
    Any new odors coming from your furnace warrant urgent investigation. If you notice a burning odor, or you can smell gas, call in the professionals right away. It may be caused by a dirty furnace that needs a professional clean, or there could be dangerous overheating. A professional will be able to check what's going on and ensure your household is safe.
  4. Rapid Cycling
    Your furnace should work steadily, reading information from the thermostat to maintain a constant temperature. If you notice the furnace is turning on and off frequently, there may be a problem. This rapid cycling could be due to a malfunctioning thermostat, a failing heat exchanger, or you may need a complete replacement.
  5. Visible Signs of Wear
    It's good practice to inspect your furnace regularly for signs of wear and tear, even if you haven't noticed a problem with the performance. Rust, cracks, or general corrosion can all indicate the furnace might not be performing at its best. More importantly, cracks can present a carbon monoxide risk, so it's vital to get any wear and tear properly checked out by a professional without delay.
  6. Aging Furnace
    No furnace can last indefinitely, so if yours is 15–20 years old, it might be time to consider a replacement. Modern furnaces are more energy-efficient so you could benefit from lower energy costs as well as reliable heating throughout your home.

Don't Wait to Arrange a Furnace Replacement in Harrisburg, PA

If you recognize any of these signs, your furnace needs to be checked professionally. Some problems may initially seem severe but can easily be repaired. However, the longer a problem continues without being repaired, the more likely severe damage can be caused.

Winter Plumbing Tips and Tricks for Harrisburg, PA, Homeowners

A Pennsylvania cold snap can leave you with frozen pipes, cracked outdoor faucets, or water damage when a pipe bursts. A few simple steps before freezing weather can help protect your home. Disconnect Hoses and Protect Hose Bibs Hose bibs are the outdoor faucets attached to your house. Remove garden hoses before freezing temperatures arrive so trapped water can drain. If your outdoor faucet has an indoor shutoff valve, close it and drain the outdoor line. Disconnect hoses from frost-free faucets, too. An insulated faucet cover adds protection, but it cannot replace proper draining. Insulate Pipes in Cold Areas Check water pipes in unheated basements, crawl spaces, and garages. Pipes near exterior walls are also vulnerable to freezing. Fit exposed pipes with pipe insulation and seal drafts near them. Insulation slows heat loss; it does not make pipes freeze-proof. Keep Warm Air Around Your Plumbing Keep your thermostat consistent during cold weather. If you leave town, keep the heat on and set it no lower than 55°F. During severe cold, open cabinet doors beneath sinks along exterior walls. Move cleaning products out of children’s reach. For exposed pipes at risk of freezing, letting the faucet run at a small trickle can help. Watch for Signs of Frozen Pipes Little or no water from a faucet during a cold snap may mean a frozen pipe. Call a plumber if you cannot locate or safely reach the frozen section. Never use a torch or open flame to thaw plumbing. Know where your main water shutoff valve is. If a pipe bursts, shut off the water immediately and arrange repairs. Address Plumbing Problems Before Winter A dripping hose bib or an unprotected pipe is easier to address before temperatures drop. Check these areas early rather than waiting for the first hard freeze. For plumbing repair and installation in Harrisburg, PA, contact W.C. Eshenaur and Son. Get help with existing problems and prepare vulnerable plumbing for winter.

Troubleshooting Your HVAC System

When your air conditioning or heating system begins to struggle in Harrisburg, PA, there's a few checks to go through that may be able to restore comfort before you need to worry about scheduling professional service for your HVAC. Basic Checks for Your HVAC in Harrisburg, PA Check the Thermostat Make sure your thermostat display isn't blank or dim; if it is, try just installing new batteries. Then, confirm that the mode is set to heat or cool according to the season. Once that's done, adjust the temperature at least three degrees beyond the current room reading and change the fan setting from continuous on to auto. After you make these adjustments, give the equipment five minutes to respond and listen for the blower or outdoor unit to start. Is It Plugged In? This question's not just for computers! Open the main breaker panel in your house and find the switches marked for the furnace, air handler, or outdoor condenser. If any lever is in the middle or off position, push it fully to the off side and then back to on. Also locate the dedicated disconnect switch, which is often mounted on or near the indoor unit and the outdoor unit. These switches can get bumped during cleaning or yard work. Once power is restored, return to the thermostat and try the system again. A tripped breaker is actually one of the most common reasons a unit refuses to start, and resetting it takes only a moment. Look at the Air Filter Find the return air grille in a hallway or ceiling, or open the access door on the side of the furnace or air handler. Slide the existing filter out and hold it up to a bright light. If you can't see any light passing through the media, or if the surface looks really gray, dusty, and packed, replace it with a new filter. A clogged filter restricts the volume of air the system can move, which causes the blower to work harder, which raises energy use, and finally often triggers safety switches that shut the equipment down. Check the Condenser Unit This is the part of the system that sits outside, and sometimes yard work and weather can cause issues. Remove any leaves, grass clippings, or twigs that have collected around the base and sides and make sure there's at least two feet of clear space on all sides so outdoor air can move freely across the coil. If the fins look dusty, rinse them gently with a garden hose on a low setting; never use a pressure washer. Is There Any Ice? Look for ice forming on the indoor coil or along the refrigerant lines. If you see some, switch the equipment off at the thermostat and allow any ice to melt completely before restarting it. Restricted airflow from a dirty filter is the most frequent cause of freezing, so the filter change you already performed will likely stop that from happening again. If it doesn't, or the filter was clean, call for help as there's a more serious issue that needs attention. If these steps don't fix things, call W.C. Eshenaur & Son, Inc. right now at 717-236-5031 to request service. We proudly serve all the towns of Central PA.
