Furnace & Boiler Repair in Mount Prospect, IL

Call 847-550-3322

Most Mount Prospect homes are ranches and split-levels, and the plumbing inside them is older than the equipment that was added later. That is why the same house can hand us a slow drain, a water heater that runs out before the last shower, a sump pump that quit during the last storm, and a furnace that will not light.

Right Away plumbing and HVAC technicians come to the house, find where the trouble actually starts, and give you a written price before any agreed work. We work from our shop at 2093 Rand Road in Des Plaines, and Mount Prospect is one of the closest areas for us to reach. Call (847) 550-3322 and tell us what you can see.

What usually goes wrong after a Mount Prospect remodel

An addition or a finished basement changes more than the floor plan. The furnace may stay where it was while the new rooms sit at the end of long duct runs, so those rooms never warm the way the rest of the house does. Finishing the lower level can also build over a drain cleanout or a sump pit; leave both reachable instead of framing them in.

A new basement bathroom usually needs its own ejector pump, which is a different job from a groundwater sump. One more shower also changes how much hot water the household needs at 7 a.m. These are planning points, not claims about a specific address.

Tell us what changed in the house and when the trouble started. That order of events tells us whether to look at drains, water heating, air movement or the furnace first.

Emergency plumber in Mount Prospect

Water where it should not be is the call we take most often: a supply pipe that has split, a shutoff that no longer turns, a water heater leaking from the tank, or sewage coming up through a floor drain. If a supply leak sits behind an accessible valve, shut the water off at the main. Stay clear of electrical equipment standing in water, and stop using fixtures that are backing up.

For a gas smell or a carbon monoxide alarm, leave the house and call the gas utility or 911 from outside. Then Call (847) 550-3322 with your address and what you can see. We tell you what to do next and when a technician can get there.

Same-day help depends on the schedule, and we do not promise a fixed response time.

Plumbing repair for leaks, fixtures and drains

Plumbing repair here usually starts with a simple question: where is the water coming from? A dripping shutoff, a weeping toilet supply or a fixture that will not drain are each a different repair, and none of them need walls opened to find out. We inspect the affected plumbing, show you the finding, and agree the price before work begins.

Drain cleaning and rodding clear the blockage first, so any further recommendation is based on a line we can actually see. Drain cleaning and rodding.

Furnace repair and cold rooms in split-levels

A ranch and a split-level move air differently, so the same complaint means different checks. Closing bedroom doors, finishing a basement or adding a room can change the air path. When a furnace stops heating, we look at ignition, flame sensing, the burner, the blower, the safety controls and a restricted filter.

If it makes heat but one room stays cold, the ducts and returns need a look too. A cold room does not automatically mean a furnace that is too small. A repair recommendation should name the fault, and a replacement quote should explain the load and the ductwork instead of copying the old unit.

Furnace diagnosis and repair.

Boiler repair, radiators and baseboard heat

Some Mount Prospect houses run hot-water radiators or baseboard instead of forced air, and a few still have steam. On a hot-water system, a cold loop usually traces to a circulator, a zone valve, trapped air or a control signal. Steam needs its own checks, including venting and condensate return.

Turning the boiler pressure up is not a cure for banging or slow radiators. We review the distribution alongside the burner and controls, because mixing up steam and hot-water procedures can leave the comfort problem sitting there even after a new boiler. If replacement is the right call, the building and the heat emitters it feeds decide the equipment.

Boiler repair and system checks.

No heat? What to tell us when you call

Say whether the furnace never starts, starts and then stops, or runs with cool air. Mention any fault code you can see, the thermostat setting and which rooms are cold. Do not keep resetting equipment; a repeated reset can hide the fault without fixing it, and combustion and safety testing belongs with the technician.

If you smell gas or a carbon monoxide alarm sounds, leave the house and contact the utility or emergency responders from outside. For a normal visit, leave clear access to the equipment and tell us about tenants or household schedules. Same-day appointments are possible when the schedule allows, and no response time is guaranteed.

Water heaters and Navien tankless installation

Running out of hot water usually points to demand, an aging tank, or a tankless unit that has not been maintained. A household can change its demand without changing the heater: another shower, a bigger tub, or three people home before 8 a.m. We compare a storage tank with a tankless unit against how your family actually uses hot water.

A tankless installation needs enough gas supply, compliant venting, drainage and room to service it, and the flow rate printed on the box is not the flow you get with cold winter inlet water. Right Away is a certified Navien installer for Navien tankless water heaters. We service other Navien equipment to the manufacturer's specifications, repair conventional tanks, and explain the descaling or maintenance the installed model needs.

Discuss the problem and schedule service.

Sump pumps and a wet basement

A sump pump is a system, not just a motor. Water enters the pit, the float starts the pump, a check valve limits return flow, and the discharge must reach an outlet that is clear. A frozen, blocked or separated discharge line can defeat a good pump.

A basement bathroom usually drains to a sewage ejector, which serves a different purpose than a groundwater sump and should not be confused with one. We find where the water is coming from before proposing repair, replacement or backup equipment. Battery backup has real limits, including battery condition and runtime, and it cannot stop a sanitary sewer backup.

Note the first wet spot and any alarm; it speeds the diagnosis. Sump-pump inspection and repair.

Drain cleaning and sewer backups

One slow sink is usually a branch drain. Several fixtures gurgling or backing up at the same time points further down the line, toward the yard lateral. Roots get blamed most often, but grease, debris, an offset joint or a low section of pipe do the same thing.

Rodding clears the obstruction; a camera through the opened line is what shows whether anything is left behind. That difference decides between routine cleaning, a localized repair or a larger replacement, and it keeps a homeowner from paying for sewer work the house does not need. Tell us which fixtures react together and how often it happens.

Cooling, mechanical service and local businesses

A house that cools everywhere except one bedroom likely has an air-distribution problem rather than a system that is too small. We check the coil, the outdoor unit, airflow, drainage and controls before talking about replacement, and an addition without a practical duct route may suit a separately sized ductless unit. Mount Prospect storefronts, offices and managed buildings need the same things homes do: rooftop heat, hot water and drains that keep working.

For commercial work, tell us who occupies the space, how we get in, and what a shutdown would affect, so the plan fits the building. Discuss the problem and schedule service.

Scheduling and what to have ready

Before we arrive, clear safe access to the furnace, boiler, water heater or sump pit, and write down anything a previous technician did. Do not remove covers from energized or gas equipment to gather information. You get a written price before the agreed work begins, and we will tell you when repair and replacement are close enough that the choice deserves a real comparison.

Same-day appointments are available for qualifying repairs when the schedule allows. Call (847) 550-3322 for the address that needs servicing. Our Des Plaines and Arlington Heights pages help nearby properties, and the guides below explain symptoms in more detail.

Mount Prospect replacement choices and plumbing repair links

The existing repair guidance is the starting point. When replacement is supported by the findings, compare furnace installation and airflow requirements with cooling replacement planning. For water problems, choose water-heater service or water leak repair according to the source.

  • Separate a furnace shutdown from a room that stays cold while heating continues.
  • Describe whether water appears during fixture use, rain or appliance operation rather than guessing which trade is needed.
  • Ask which existing ducts, pipes and controls remain, and what limitation the proposed work is intended to correct.

Water at the base of a water heater may come from a connection, a valve, relief discharge or the tank itself, and each leads to a different decision. Our guide to a water heater leaking from the bottom explains how the source is found before repair or replacement is chosen.

Mount Prospect plumbing and HVAC FAQs

Who repairs furnaces in Mount Prospect?
Right Away diagnoses furnace no-heat, ignition, blower, airflow and control problems in Mount Prospect. Call 847-550-3322 with the equipment type and symptom. We serve the village from Des Plaines and provide a written price before work begins.
Why is one floor of my Mount Prospect split-level cold?
The cause can be restricted airflow, inadequate returns, duct changes or a control problem. If the furnace makes heat normally, its capacity is not the only issue to investigate. We check the affected floor and the heating system together.
How much does a Mount Prospect boiler repair cost?
The diagnosed fault, parts and access determine the price. A zone-control repair differs from a leaking boiler section. We explain the finding and provide written pricing before the repair; a website estimate cannot identify your system's actual problem.
Can you install a Navien tankless unit in a ranch house?
Yes, where the property's demand, gas supply, venting and service access support the proposed installation. Right Away is a certified Navien installer. We compare a suitable tankless setup with a conventional tank rather than choosing by the home's style alone.
Does a backup sump pump prevent every basement flood?
No. Backup equipment has limited capacity and runtime, and does not repair a damaged sewer or stop every groundwater event. We check the primary pump, pit and discharge first, then discuss backup options and maintenance.
Do repeated drain backups need camera inspection?
A camera can help explain a recurring backup after the line has been opened. It may show roots, offsets or damage, while a branch blockage can require a smaller drain repair. The affected fixtures and visible pipe condition guide the recommendation.
Do you repair AC and heating for Mount Prospect businesses?
Yes. We provide cooling, heating, plumbing and mechanical service for commercial properties as well as homes. Describe equipment access, occupancy and shutdown constraints when scheduling so the proposed work can be planned realistically.
