HVAC & Plumbing Questions
Below are answers to the most common questions we receive about heating, cooling, plumbing, and drain services in Southeast Idaho.
How often should a furnace be serviced in Idaho?
HVAC professionals recommend servicing your furnace once per year before winter. In Southeast Idaho, where temperatures regularly drop below freezing between November and March, annual furnace maintenance is especially important. A tune-up includes cleaning the heat exchanger, inspecting the ignitor, testing safety controls, and checking airflow. Regular maintenance extends equipment life, improves efficiency, and prevents breakdowns during the coldest months. Ironsharp Home Services provides furnace tune-ups throughout American Falls, Pocatello, Chubbuck, and surrounding communities.
Why is my furnace blowing cold air?
A furnace blowing cold air is usually caused by a faulty ignitor that fails to light the burner, a dirty air filter blocking airflow and triggering a safety shutoff, a malfunctioning limit switch that cuts heat prematurely, or a thermostat set to fan-only mode instead of heat. In some cases a cracked heat exchanger can cause the system to shut down as a safety measure. If your furnace is running but not producing heat, turn off the system and call a professional. Ironsharp Home Services diagnoses furnace problems throughout Southeast Idaho.
How long do HVAC systems typically last in Idaho?
Most residential furnaces last 15 to 20 years with proper annual maintenance. Air conditioning systems typically last 10 to 15 years. In Southeast Idaho, where systems work hard through both cold winters and hot summers, regular maintenance is critical for reaching the top of that range. Systems that are not maintained often fail within 10 years. If your HVAC system is over 12 years old and requires frequent repairs, a replacement evaluation may save money long-term. Ironsharp Home Services offers honest assessments — we will tell you whether repair or replacement makes more sense for your situation.
Why is my air conditioner not cooling my home?
An air conditioner that runs but does not cool is most often caused by a refrigerant leak, a frozen evaporator coil, a dirty condenser coil blocking airflow, or a failing compressor. Low refrigerant levels prevent the system from removing heat effectively. Frozen coils are frequently caused by restricted airflow from a dirty filter or blocked vents. If your AC is running constantly but your home stays warm, turn the system off and check the filter first. If the problem continues, call a professional. Ironsharp Home Services provides AC diagnostics and repair throughout Pocatello, Chubbuck, American Falls, and Southeast Idaho.
When should I replace my HVAC system instead of repairing it?
Consider replacement when your system is over 10 to 12 years old and repair costs exceed 50 percent of a new system's price. Other signs replacement may make more sense: frequent repairs, significantly higher energy bills, difficulty maintaining consistent temperatures, or the system uses R-22 refrigerant which is no longer manufactured. Modern systems are significantly more energy efficient. Ironsharp Home Services provides honest evaluations — we explain the repair and replacement options and let you decide what fits your home and budget.
Do you offer emergency HVAC service in Southeast Idaho?
Yes. Ironsharp Home Services provides emergency HVAC response throughout Southeast Idaho, including American Falls, Pocatello, Chubbuck, and Blackfoot. The owner responds personally to emergency calls. A $300 after-hours call-out fee applies outside regular business hours, Monday through Saturday, 7 AM to 7 PM. If your furnace stops working during an Idaho winter or your AC fails during a summer heat event, call (208) 909-6815 for immediate assistance.
What causes sewer line backups in Idaho homes?
The most common causes of sewer line backups in Southeast Idaho homes are tree root intrusion into pipe joints, grease and soap scum buildup on pipe walls, collapsed or cracked pipe sections from ground movement or age, and blockages from debris like paper towels or wipes. Older homes with cast iron drain lines are especially prone to scale buildup that narrows the pipe over time. Ironsharp Home Services uses professional drain cameras to identify the exact cause and hydro jetting equipment to clear blockages throughout American Falls, Pocatello, Chubbuck, and surrounding communities.
How do tree roots get into sewer lines?
Tree roots enter sewer lines through small cracks, loose joints, or deteriorating seals in older pipe sections. Roots naturally follow moisture — even vapor escaping from a pipe is enough to attract them. Once inside, roots grow rapidly and create dense blockages that trap debris. In Southeast Idaho, mature trees near homes are a significant cause of drain backups and sewer line damage. A professional sewer camera inspection identifies root intrusion before it becomes a full blockage. Ironsharp Home Services provides drain camera inspection and root removal through hydro jetting.
What is hydro jetting and when is it used?
Hydro jetting uses high-pressure water — typically 3,000 to 4,000 PSI — to scour the interior walls of drain and sewer pipes, removing grease buildup, scale, root debris, and blockages that snaking cannot fully clear. Unlike a drain snake, which only punches through a clog, hydro jetting cleans the full diameter of the pipe. It is most commonly used for recurring drain problems, grease buildup in kitchen lines, root intrusion, and blocked sewer mains. Ironsharp Home Services provides hydro jetting throughout American Falls, Pocatello, and Southeast Idaho.
Can drain cleaning damage older pipes?
Hydro jetting is generally safe for most residential drain and sewer pipes including PVC, ABS, and cast iron in good condition. However, pipes that are already severely corroded, cracked, or structurally compromised can be affected by high water pressure. A professional sewer camera inspection before hydro jetting identifies any pipe conditions that require a different approach. Ironsharp Home Services includes a complimentary camera inspection with every drain service so you can see exactly what is inside your pipes before any cleaning begins.
How do plumbers clear clogged sewer lines?
Professional plumbers use two primary methods to clear sewer line clogs: mechanical drain snaking and hydro jetting. A drain snake uses a rotating cable to break through or retrieve blockages. Hydro jetting uses high-pressure water to scour the pipe walls clean. For root intrusion, hydro jetting is typically more effective. For a collapsed or severely damaged pipe, repair or replacement may be required. Ironsharp Home Services begins with a camera inspection to identify the exact cause, then recommends the most effective solution for your specific situation.
What should I do if my sewer backs up?
Stop using water in the home immediately — running faucets, flushing toilets, or running the dishwasher will worsen the backup. Avoid chemical drain cleaners, which are ineffective on sewer blockages and can damage pipes. Keep children and pets away from any overflow area. Then call a professional plumber as soon as possible. Sewer backups can expose your home to sewage contamination and water damage if not addressed quickly. Ironsharp Home Services provides emergency drain and sewer services throughout Southeast Idaho. Call (208) 909-6815.
When should I call an emergency plumber?
Call an emergency plumber immediately if you have a burst pipe, sewer line backup, gas line leak, water heater failure causing flooding, or loss of water to the entire home. These situations can result in structural water damage, health hazards, or safety risks if you wait until regular business hours. Ironsharp Home Services provides emergency plumbing response throughout American Falls, Pocatello, Chubbuck, and Southeast Idaho. Call (208) 909-6815 for immediate assistance.
Why is my water pressure low throughout my house?
Low water pressure throughout your entire home usually points to a failing pressure reducing valve that controls pressure from the city main, significant mineral buildup or corrosion inside older galvanized pipes restricting flow, or a leak in the main supply line losing pressure before water reaches your fixtures. If only certain faucets have low pressure, the issue is more likely a clogged aerator or partially closed fixture valve. Ironsharp Home Services diagnoses water pressure problems and restores normal flow throughout American Falls, Pocatello, and Southeast Idaho.
Why does my toilet keep running?
A running toilet is almost always caused by a faulty flapper valve that fails to seat properly after flushing, allowing water to continuously drain from the tank into the bowl. A worn fill valve that cannot shut off completely, or a float set too high causing overflow into the overflow tube, are the other common causes. A running toilet can waste between 20 and 200 gallons per day. While a flapper replacement is often a DIY fix, persistent running after replacement usually indicates a worn fill valve or damaged flush valve seat requiring professional repair. Ironsharp Home Services handles toilet repairs throughout Southeast Idaho.
What causes drain odors in my home?
Foul odors from drains are most commonly caused by dried-out P-traps — the U-shaped pipe section under drains that holds water as a barrier against sewer gas. If a drain is rarely used, the trap dries out and allows sewer gas into the home. Other causes include biofilm buildup from soap and organic debris on pipe walls, a blocked drain vent preventing proper airflow, or a sewer line problem allowing gas to escape. Persistent odors from multiple drains simultaneously often indicate a venting issue or sewer line fault that needs professional inspection.
How do I know if I have a collapsed sewer line?
Signs of a collapsed or severely damaged sewer line include multiple drains backing up simultaneously, sewage odors from drains or yard areas, soggy or sunken spots in your yard above where the sewer line runs, and foundation cracks or settlement near the line. A single slow drain is usually a local blockage. Multiple slow drains and gurgling from unused fixtures at the same time suggest a main line problem. A professional sewer camera inspection is the only way to confirm a collapsed section. Ironsharp Home Services provides camera inspection and sewer line repair throughout Southeast Idaho.
What is a drain camera inspection?
A drain camera inspection involves running a waterproof camera mounted on a flexible cable through your drain or sewer line to visually inspect the interior of the pipe. The camera transmits live video so a plumber can identify the exact location and cause of blockages, root intrusion, cracks, bellies where debris collects, or collapsed sections. Ironsharp Home Services includes a complimentary camera inspection with every drain service — no guesswork, no hidden fees. You can see exactly what is happening inside your pipes before any work begins.
