7 Signs Your HVAC System Needs Repair

A home is a place where people should feel comfortable and relaxed. When you are at home, your HVAC system can provide the perfect temperature for comfort and relaxation. However, if your HVAC system starts to break down or shows signs of needing repair, then it will not do its job efficiently anymore.

If you're a homeowner, then you know how important it is to have a working HVAC system. Wouldn't you be frustrated if your home had no air conditioning during the summer? Or if your heating system broke down and there was no heat in the winter? Many homeowners experience problems with their HVAC systems at some point in time. This blog post will outline signs that indicate that your HVAC needs repair so that you can get it fixed before it breaks down completely!

Change in Airflow

Have you been experiencing uncomfortable drafts, hot and cold spots around the house, doors slamming by themselves, and unexplained whistling noises? All of these could be symptoms of air pressure problems caused by poor airflow from your HVAC system.

Ignoring airflow problems for too long can put a strain on your system, which can lead to compressor failure.

Increased Energy Bill

If you've noticed that your electric bills are higher than usual, it may indicate dirty air filters and failing parts. For example, a duct leak reduces the efficiency of the system to distribute air throughout your home, which will drive up costs if not fixed quickly. If there is a malfunction with any equipment in the AC unit like the motors, capacitors, and compressor, then they could lead to high energy usage.

Strange Sounds and Odors

Hearing funny noises like clunking, squeaking, grinding, rattling, or scratching, burning, or musty odor from your vents when you switch on your system can be an indicator that your unit needs cleaning, maintenance, replacement of parts, or a complete overhaul.

Excess Humidity and Dust

Have you noticed a buildup of moisture or dust in your house? If so, it might be time to call in the HVAC experts because excess humidity and dust can create the ideal environment for mold and mildew growth and can cause several health concerns.

Unit Constantly Goes On and Off

Your HVAC system operates in cycles to maintain a specific temperature in your home. When the AC is cycling, it's working towards reaching that desired level, and when this point is reached, it will shut off until its next cycle begins. However, if you notice an on-off pattern of short intervals from your air conditioner, then there may be some issues developing with the machine or thermostat settings such as low refrigerant levels, iced evaporator coils, dirty filters, or clogged vents.

Water Leaks Around the Unit

If you notice any spilling, freezing, or puddling in or close to your unit, it can be a sign of more than one issue. It may be the result of a blockage in your buildup line. Buildup that may freeze on the unit's coils that could spill out and form puddles on the ground.

Another reason could be a problem with the drain tube or condenser unit.

A more severe issue could be if your HVAC unit is leaking refrigerant, which can cause health problems, so get it checked right away.

The System is Getting Old

If you have had your HVAC system for a while, it is just a matter of time before it starts throwing out hot air in summers and cold air in winter – i.e., it stops working properly. Basically, the older your system gets, the more issues it will develop.

If you have been experiencing any of the above problems, we recommend scheduling an appointment with a professional HVAC technician to have your HVAC unit checked out.

Top Plumbing Upgrades for Local Businesses

Plumbing might not be the first thing that comes to your mind when you think about running your business, but it's essential to your daily operations, customer satisfaction, and thus your bottom line. Talk to your Northbrook, IL commercial plumbing services professional to find out what options will be best for your space and keep reading for some general upgrades that are often helpful for a business. Top Plumbing Upgrades for Local Businesses more Water-Efficient Fixtures A simple but huge upgrade is to replace any standard water fixtures you have with water-efficient models. This might be sensor-activated faucets in a bathroom, dual-flush toilets with options for a full or partial flush, and fixtures that concentrate a water stream at a sink or shower so you can still get strong cleaning power but with less water usage. Items like this can enormously cut your water usage while still performing as they need to. Customers are often pleased by options like this, too, because fixtures that don't have to be touched promote hygiene by minimizing contact. Even better? Upgrading to these options could qualify you for rebates through programs like EPA WaterSense. Backflow Prevention Contaminated water poses a serious threat to any business. You're talking about the possibility of health issues, damage to your reputation, and even legal and regulatory penalties. A simple backflow prevention device, like a reduced pressure zone valve or double check assembly, will keep dirty water from irrigation systems or industrial processes out of the clean water supply. This is especially good for any business dealing with serious chemicals, such as an auto repair shop. Upgrading Pipes and Drainage Systems For any business in an older building, it's always worth investigating whether aging pipes and bad drainage are causing leaks that waste your money, clogs and backups that disrupt your day, and the constant need for expensive repairs. While it is an investment to upgrade your pipes and drains, transitioning to corrosion-resistant materials will fix these constant problems and also extend the lifespan of the entire system. If you use a lot of water, such as in a restaurant business, we can also install oversized drain lines that will improve the flow and reduce the likelihood that you're going to have an overflow during your busiest periods. Smart Technology It's 2025, and no home or business should be without a smart leak detection system. These systems can monitor your water usage and instantly let you know if anything is different from normal. This can protect you from small hidden leaks that not only waste your money but could also cause structural damage over time, and you can even get devices with automatic shut-off features that will stop the water flow if something big happens when no one is there.

How Horizontal Boring Can Save Your Yard During Plumbing Work in Northbrook, IL

Northbrook homes are known for mature trees, established landscaping, and well-maintained yards. When a main water line or sewer pipe fails, many homeowners assume the repair will mean tearing up the lawn, driveway, or garden beds. Traditionally, that was true. Today, horizontal boring offers a way to replace underground pipes without destroying the property you’ve invested years maintaining. Bill’s Plumbing and Sewer uses horizontal boring, also called trenchless boring or directional drilling, to complete major plumbing work while keeping surface disruption to a minimum. How Horizontal Boring Works more Horizontal boring allows plumbers to install or replace underground pipes without digging a long trench across the yard. Instead of excavating the entire path, the work is done almost entirely below ground. The process starts by setting up a compact drilling rig in a small access area, usually near the street or foundation. A pilot hole is drilled underground at a controlled angle, following the path of the existing pipe or a new route that avoids obstructions. Once the pilot hole reaches the endpoint, a larger reamer is pulled back through the soil while the new pipe is installed at the same time. In most cases, the job requires only two small access points. Everything between those points stays intact. Why Horizontal Boring Makes Sense for Northbrook Properties Preserving Landscaping and Lawns Many properties throughout Cook County feature sloped yards, decorative stonework, irrigation systems, and established plantings. Traditional trenching cuts through all of it. Restoring a yard after excavation can add thousands of dollars to a repair project. Horizontal boring avoids that damage and helps protect both landscaping and soil stability. Protecting Mature Trees Large trees are common throughout Northbrook neighborhoods, and their root systems often spread wide and shallow. Open trench excavation severs those roots and can permanently damage or kill a tree. Horizontal boring typically runs several feet below the root zone, reducing the risk to trees that would otherwise be lost. Faster, Cleaner Projects Trenchless boring usually takes less time than traditional digging. There is less soil to manage, fewer disruptions, and less risk of delays due to weather. In a region where rain and seasonal ground conditions can complicate excavation, minimizing surface work keeps projects moving. When Horizontal Boring May Not Be the Right Option While horizontal boring is a strong solution in many situations, it is not always the best choice. Extremely rocky soil, unusually long pipe runs, or services with multiple sharp turns can make boring more complex or less cost-effective. Very shallow pipes located directly beneath concrete may still require limited excavation. Before recommending trenchless work, Bill’s Plumbing and Sewer evaluates the property, soil conditions, and pipe layout. In some cases, a small test pit may be needed to confirm whether boring is the right approach. Choosing the Right Method for Your Plumbing Repair Not every plumbing problem requires trenchless technology, but when it does, the benefits are significant. Horizontal boring allows critical water line and sewer repairs to be completed while protecting the yard, trees, and hardscaping that make Cook County homes valuable and enjoyable. To find out whether horizontal boring is the right solution for your water or sewer line issue, contact Bill’s Plumbing and Sewer in Northbrook, IL. Our team will evaluate your situation and explain the best option for your property before work begins.

How to Repair a Furnace: A Practical Guide for Homeowners

When a furnace stops working, panic usually follows—especially during a Northbrook winter. Many breakdowns come from a few predictable issues, and some basic checks can be done safely before calling for professional furnace repair. This guide walks you through simple troubleshooting steps and explains when it is time to contact Bill’s Plumbing & Sewer, your local expert for furnace repair near me in Northbrook, IL. Whether the problem is a noisy system, poor airflow, or a furnace that will not start at all, this tutorial helps you understand what is happening and what you can do about it—up to the point where a trained furnace repair technician should step in. Start with the Basics: Simple Furnace Troubleshooting more Before assuming the worst, it makes sense to rule out small, common issues. Many calls for heating furnace repair begin with problems that do not require major work. Check the Thermostat Confirm the thermostat is set to HEAT. Increase the set temperature by a few degrees. Replace the batteries if the display is dim or blank. A large share of “no heat” situations start and end at the thermostat. Verify the Furnace Power Switch Most furnaces have a wall switch that looks like a regular light switch. If it is off, the furnace will not run. Turn it on and give the system a few minutes to respond. Inspect the Air Filter A clogged filter can overheat the system, reduce airflow, and trigger a shutdown. If the filter is dirty, replace it. This simple step protects the system and often restores normal operation without further furnace repair. Try a Single Reset Some gas and oil furnaces have a reset button that will lock out the burner for safety. Press the reset button only once. If the furnace still will not run, avoid repeated resets and move on to deeper diagnosis or professional help. Common Furnace Problems and What They Mean Not every problem is safe to handle on your own, but understanding the most common failure points helps you make better decisions. These are typical furnace parts that often require repair or replacement: Furnace ignitor Flame sensor Draft inducer motor Furnace blower motor Limit switch Burner assembly Furnace control board Heat exchanger Gas valve Furnace capacitor Ignitor Failure If the ignitor fails, a gas furnace will not light. You may hear clicking but see no flame. Ignitors are fragile and run at very high temperatures. This is not a good candidate for DIY work; replacement is best handled by a qualified gas furnace repair technician. Blower Motor Problems Weak airflow, no airflow, humming sounds, or a burning smell can point to a failing blower motor. Furnace blower motor repair often involves electrical testing and motor replacement. This type of work should be done by a professional due to the electrical and mechanical risks involved. Dirty Flame Sensor The flame sensor confirms that the burner has lit. If it becomes coated with residue, the furnace may light briefly and then shut off. Basic cleaning procedure: Turn off power to the furnace. Remove the flame sensor carefully. Gently clean it with fine steel wool. Reinstall and restore power. If the furnace now stays on, the issue was likely limited to the sensor. If not, professional heating furnace repair is the next step. Oil Furnace Issues With oil furnace repair, clogged nozzles, dirty burners, or fuel delivery issues are common. You can confirm the oil tank is not empty and change an accessible filter, but nozzle cleaning, burner adjustment, and combustion testing require specialized tools and training. Those jobs belong in the hands of an experienced technician. How Much Does Furnace Repair Cost? The f urnace repair cost depends on the failed part and the complexity of the work. Minor repairs often fall in a lower price range, while major repairs such as blower motor replacement, control board replacement, or extensive gas furnace repair can be more costly. Oil systems can be slightly more expensive to service than basic gas furnaces, especially if burner components or venting need work. When you search for furnace repair near me or gas furnace repair near me, the most important factor is choosing someone who can diagnose the issue correctly the first time. A misdiagnosed problem can quickly make any repair more expensive than it needs to be. When to Call a Furnace Repair Technician Some issues are reasonable to inspect on your own. Others call for professional help to keep your home safe. A licensed furnace repair technician should handle the problem when: You smell gas or suspect a leak. The furnace short-cycles or turns on and off rapidly. The blower never turns on or never turns off. You hear grinding, scraping, or metal-on-metal noises. The breaker trips when the furnace runs. There is visible water around the base of the furnace. You suspect a cracked heat exchanger or carbon monoxide risk. These are not simple fixes. They involve combustion, fuel lines, high voltage, or venting. In these cases, the right move is to bring in a company that regularly handles heating furnace repair and full system diagnostics.
