Seasonal Heating, Ventilation, and Air Conditioning Maintenance for Fall and Winter

When the mercury drops and your home feels chilly, the worry sets in fast. A no-heat situation in February is more than uncomfortable. It can be unsafe for vulnerable family members and can risk frozen pipes. The good news is that many heating hiccups have quick fixes, and when they do not, a licensed technician can usually diagnose the root cause the same day. This guide walks you through safe, simple checks you can do right now, what common furnace issues look like in deep winter, how to think about repair versus replacement, and what the $5,000 rule really means. We will also cover when homeowners insurance may apply. If you are in the Fox Valley or Chicagoland, U.S. Allied offers 24/7 dispatch, same-day diagnostics, and maintenance plans to keep your system steady through the coldest nights. First, a safe DIY checklist Start with the items you can check without opening panels or reaching into equipment. Thermostat: Make sure it is set to Heat, the temperature is above room temp, and the fan is on Auto. If you use a heat pump with auxiliary or emergency heat, select Heat, not Cool or Off. Replace thermostat batteries if you see a low battery icon. Air filter: A clogged filter can trip safeties and cause short-cycling or weak airflow. Replace a visibly dirty filter with the same size and orientation. If the filter is freshly replaced, re-seat it to ensure it is not restricting airflow. Breakers and switches: Check the furnace switch (looks like a light switch near the unit) and your electrical panel. Reset a tripped breaker once. If it trips again, call a pro. Gas supply visibility: Confirm that the furnace gas shutoff valve handle is parallel to the pipe. If you smell gas, leave the home and call your gas utility and 911, then contact an HVAC professional. Vents and returns: Open supply registers and keep returns unblocked. Furniture and rugs can starve airflow. Outdoor unit (for heat pumps): Clear snow and ice from around the unit so it can breathe. If these steps do not restore heat or you are not comfortable doing them, contact a licensed technician. In subfreezing weather, no heat can escalate quickly. U.S. Allied provides 24/7 dispatch in North Aurora, Naperville, Batavia, St. Charles, and nearby communities. Common February heating problems, explained Understanding the symptoms helps you communicate clearly when you call. No heat: Often linked to a tripped safety, a failed igniter or flame sensor, a clogged filter, or loss of power. On heat pumps, heavy frost can trigger a defrost cycle that temporarily reduces heat. Short-cycling: The system turns on and off every few minutes. Common causes include dirty filters, blocked vents, an oversized furnace, or a faulty limit switch. Strange noises: Rattling can signal loose panels or ductwork. Whistling points to airflow restrictions. Banging at startup can indicate delayed ignition. Screeching may be a failing blower motor or belt. Emergency heat confusion: On heat pumps, Emergency Heat is a manual backup mode that uses electric strips or a gas furnace to heat when the heat pump cannot. It is normal for Emergency Heat to feel different at the vents and to cost more to run. Why is my emergency heat blowing cold air? A few reasons can make vents feel cool or lukewarm: Heat pump in defrost: In freezing weather, the outdoor unit defrosts by reversing briefly, which can send cooler air indoors. The system should return to heat within minutes. Electric strips not energizing: If auxiliary electric heat strips fail, you will feel cooler air. This needs diagnosis by a technician. Fan-only setting: If the thermostat fan is set to On, the blower runs continuously and may move air even when heat is not active. Set it to Auto. Duct or filter issues: Airflow restrictions or leaks reduce supply temperature at registers. If Emergency Heat runs more than an hour with no improvement, or if breakers trip, call for service.

Consider: Age: The average lifespan of a house furnace is typically 15 to 20 years with regular maintenance. Some last longer, and heavy use or deferred maintenance can shorten life. Safety: Cracked heat exchangers and repeat ignition failures are red flags. Safety issues usually push toward replacement. Frequency of breakdowns: Multiple major repairs in a short span suggest end-of-life. Efficiency: Older units often have lower AFUE ratings and higher operating costs. What is the $5,000 rule for HVAC? A common guideline helps weigh cost versus age. Multiply the estimated repair cost by the system’s age in years. If the product exceeds $5,000, replacement often makes more financial sense. Example: A 14-year-old furnace with a $500 repair has a product of $7,000, which leans toward replacement. It is a rule of thumb, not a mandate, and your decision should factor safety, comfort, energy costs, and timing. Is it cheaper to repair or replace a heater? It depends on age, condition, and the specific failure. For newer equipment with a clear, one-time issue, repair is usually cheaper. For older systems where repairs approach 30 to 50 percent of replacement cost, or when reliability is in question, replacement often saves money over the next few winters due to fewer service calls and better efficiency. A licensed technician can provide both estimates and help you compare. When insurance may help Homeowners insurance usually covers sudden and accidental damage, not wear and tear. Examples that may be covered include fire, certain electrical events, or a covered peril that damages the furnace. Typical exclusions are age-related failures, corrosion, or mechanical breakdown from normal use. Policies vary by carrier. Document the issue with photos and technician notes, then call your insurer to confirm coverage. If water damage occurs alongside a heating failure, such as frozen or burst pipes, professional documentation will also help your claim. Quick action protects your home and simplifies conversations with your insurance adjuster. How U.S. Allied helps in deep winter You get straightforward diagnostics, clear options, and licensed work.

Multiply repair cost by system age. If the total is over $5,000, replacement often makes more sense. Use it as a guideline alongside safety and efficiency considerations.

Plumbing trouble never checks your calendar. It happens at 2 a.m., during a deep freeze, or right before guests arrive. When it does, you need calm, clear steps you can take right now to protect your home until help gets there. This guide explains what counts as a true emergency, what to do first to limit damage, how fast a plumber can arrive in Chicagoland winters, what after-hours pricing typically looks like, when insurance may help, and what to say when you call.

What qualifies as a plumbing emergency? Call for emergency service if any of the following are happening: Burst or actively leaking pipes. Especially in freezing weather or if water is spreading rapidly into ceilings, walls, or floors. Sewer backup. Multiple drains gurgling, sewage smell, toilets not flushing, floor drains overflowing, or water backing up when you run fixtures. No water at all. A complete loss of water service requires immediate attention, particularly in winter. Major leaks you cannot contain. For example, a failed water heater tank, a supply line leak under a sink that will not stop, or a washing machine hose that has burst. Gas water heater issues with the smell of gas. Leave the home and call your gas utility and 911 first, then call us. No heat in subfreezing temperatures. Protecting people, plumbing, and property matters. Our HVAC team is available for urgent heating calls as well. If you are unsure, call. We will help you decide if it is safe to wait or if a tech should come right away. What to do first to limit damage Take these quick, safe steps while you wait for the technician: 1. Shut off the water Main shutoff: Find the main valve where water enters your home, often near the perimeter wall in the basement, mechanical room, or crawlspace. Turn it clockwise. Fixture shutoff: For a leak isolated to a sink, toilet, or appliance, close the small angle stop valve under or behind the fixture to avoid cutting water to the whole house. 2. Kill power near water If water is near outlets, a breaker panel, or appliances, switch off the affected circuit at the breaker panel. Do not step in standing water to reach electrical panels. 3. Reduce pressure and drain lines After shutting water off, open lower-level faucets and a bathtub to relieve pressure and drain remaining water from lines. 4. Protect your space Move valuables, rugs, and electronics away from the leak. Use buckets and towels to contain drips. If you have safe access, place a pan under the leak. 5. Take photos and notes Document the issue and any damage for your insurance claim. Photos before cleanup can speed approvals. 6. Prevent freezing spread In extreme cold, keep indoor doors open, set the thermostat to at least 68°F, and avoid turning the heat off. If a pipe is frozen but not leaking, keep faucets slightly open and wait for professional help. If a sewer backup is suspected, avoid using water anywhere in the house. Do not run sinks, showers, dishwashers, or washing machines. How quickly can a plumber come in Chicagoland winters?

Does homeowners insurance cover emergency plumbing? Coverage depends on your policy and the cause of loss: Sudden and accidental damage is often covered. For example, a burst pipe that damages ceilings or floors may be eligible for coverage of the resulting water damage. Wear and tear or neglect are typically not covered. A slow drip that was not addressed for months may be excluded. Sewer backups may require a rider. Many policies need an added endorsement for sewage or drain backup claims. Keep documentation. Photos, time of discovery, steps you took to mitigate damage, and invoices help the claims process. Call your insurer if damage is significant. They can advise whether to start a claim and what to do next. We can provide professional documentation and repair reports to support your claim. What do I say when calling a plumber? Keep it simple and specific. Here is what helps dispatch quickly: Your location and best callback number.
