Providing Heating Repair and Replacement Services in Merced Since 1960

It can get cold in Merced when winter rolls around. And, if you want to live comfortably, you need a reliable, affordable way to heat your home. For many people in our area, that may mean replacing their old furnace or heater with a new one. Unfortunately, like all things, home heating systems don’t last forever—especially without regular maintenance visits from an HVAC professional. They break down and eventually need to be replaced.

In colder months, going without heat isn’t really an option. Beyond comfort, it can mean survival. And, being without heat can also pose a hazard to your house and fixtures. That’s why, when it comes to furnace and heater repairs in Merced, you shouldn’t settle for just any Merced County HVAC contractor. You should call Johnson Plumbing Inc..

A Layman’s Explanation of How Furnaces Work

Understanding and appreciating your home’s heating system is the first step to getting the most out of it.

A furnace is the indoor piece of HVAC equipment used to distribute heat throughout a home or business. This is accomplished by warming air and then forcing it out to each room. As the heated air is circulated, it raises the temperature until the thermostat tells it to stop. The typical heating cycle goes something like this:

Electricity, heating oil, propane, or natural gas, enters your home from either the utility's network or your home's heating fuel tank.
When the interior of your home starts to cool, the thermostat sends a call for heat to your furnace.
When the furnace is told by the thermostat that heat is needed, the burner ignites the gas in an enclosed metal vessel called a heat exchanger. The fuel byproducts are then expelled through your exhaust vents. This stops potentially toxic gases from mixing with your home’s interior air.
A minute or so after igniting the gas, the blower pulls air into the furnace through your ‘return air’ ductwork, and then pushes it across your furnace's now-hot heat exchanger.
The furnace's heat exchanger transfers the heat from the burning fuel inside it, to the air passing over it.
Your furnace’s blower fan continues to push the warmed air throughout your home until your target temperature is reached.
Once the desired temperature is reached, your thermostat turns off the gas valve and stops the flow of warm air.

Fun Fact: The word furnace is derived from the Latin word fornax, meaning oven. Since propane and gas furnaces weren’t invented until the 1880s, this word predates them by a millennia!

Boiler Services

If you have baseboard heat or radiators, you likely have a boiler system. Common in older homes, these systems use heated water or glycol to transfer heat to all the rooms in your home. When the heat is released into the rooms, the water returns to the boiler to be reheated and pushed back out. With longer lifespans than conventional systems, these units require a specialist to fix. Fortunately, our Merced HVAC experts are boiler repair and replacement experts.

What to Look for in a Heating Contractor

Your heating system is a major component of your home’s comfort systems. It represents not only safety in winter but also a significant financial investment. That’s why it’s vital that you select the right person to repair and maintain your home's heater.

Here in Merced, there are plenty of HVAC companies to choose from. The below characteristics, however, are what separate the pros from more questionable heating contractors:

Current Licensing: In California, only contractors who meet certain training and skill requirements can obtain a license. The presence of a valid license is the best sign of a qualified HVAC contractor in Merced. To see if a potential heating company has one, check out their website. If you cannot find a license number, call the business and ask for it.
Comprehensive Insurance: What happens if a Merced heating technician makes a mistake while working on your heater? Do you know who pays medical bills if that same person hurts themselves on your property? These two scenarios are why it’s vital that your chosen Merced heating company carries up-to-date insurance. This is something we provide to ensure your peace of mind.
Glowing Reviews: Check out a contractor's online review profiles. What do former clients say about them? Do you know anyone who has used them before? If so, ask if they’d refer them for heating repair or installation work in Merced. If they have a few negative reviews, don’t write them off. What matters most is how they handled the situation and if they responded in a professional, caring manner.
Experience and Expertise: When it comes to heating service in Turlock or Merced, experience should top your list of requirements. The more years of experience an HVAC contractor or company has, the better able they are to quickly pinpoint what’s wrong with your heating system. They also tend to be more adaptable and come carrying the right equipment and parts.
Warranties and Guarantees: Things can go wrong with even the newest heating or cooling system. How it's installed can be the cause. That’s why it’s vital to choose a heating company with a comprehensive warranty and guarantee policy. At minimum, your satisfaction should be acknowledged.

Special Offers and Rebates: Check out what kinds of deals the company is offering. Does it align with your current heating needs? If so, print off the coupons and keep them on hand. You can check out our special offers page for discounts.

As you might guess, we possess all of the characteristics above. Reach out to us at (209) 723-4032 to schedule heating service in Turlock or Atwater.

Frequently Asked Questions

Do I really need furnace maintenance in Merced?

We suggest having your heater or furnace examined on a regular basis. A lot of heating failures occur because this vital part of homeownership is ignored in favor of a ‘fingers-crossed’ approach. During your inspection, our HVAC expert will look for signs of damage. They will also clean any dust away and test electrical components. From improved efficiency to manufacturer warranty requirements, there’s few better ways to protect your heating system. You can reach out to us at (209) 723-4032 to schedule your furnace tune-up in Merced.

Which brands of furnaces and heating products does Johnson Plumbing Inc. work on?

What do I do if my heat goes out?

Is power getting to your furnace or heater? Is a fuse or circuit breaker tripped? Make sure your power switch is in the ON position.
When was the last time you swapped out your filter? If it’s been a while, try installing a new filter first. This can solve a lot of heating problems.
Verify your thermostat is set to “heat” and not “cool”. If you notice the display is dim, try swapping out the batteries on the back of the unit.
Is there snow or other debris blocking your outdoor vent? If so, remove the obstruction. This will allow your system to work more effectively.

If you still don’t have heat, it’s time to contact us for Merced heating services at (209) 723-4032.

How can I reduce my heating bills?

The most obvious way to reduce heating bills in Merced is to install a new heating system. But it’s not the only way to take a bite out of gas and electric bills. You can also:

Lower Your Thermostat: Turning your thermostat down 10 degrees can reduce energy use by roughly a third. If that’s too cold to stomach, each degree will save around three percent.
Get Rid of Air Leaks: Heat often escapes through holes in your home or ductwork. In older homes, this accounts for between 25 and 40 percent of all heat lost. Sealing these leaks not only prevents drafts but also lowers your energy bills.
Service Your Heating System: Yearly tune-ups on your heating system are a great way to lower your heating budget. During these service calls, our Merced HVAC technicians will clean your boiler or furnace, allowing it to operate more smoothly and efficiently.
Install Better Insulation: Insulation is one area where home builders often cut costs. You might be surprised by how cost-effective getting your home reinsulated is. We suggest calling a local Merced insulation contractor for a better idea of the type of savings you can expect.
Cover Your Windows: The Department of Energy estimates that 30% of all heat is lost through the windows. While old ones should be replaced, even newer ones can leak warmth. Adding floor-length curtains helps keep the warmth from your heating system inside.
Check the Vents: Now’s the time to make sure the vents are unobstructed. Are they dusty? Take off the plates and clean them. This simple step will allow the heat in your home to flow more easily and evenly throughout your home.

How much does a new furnace cost in Merced?

The cost of a furnace installation is dependent on several factors including the type of furnace being installed, how much extra work is involved, and how large of a furnace you’ve chosen. Your home may also have two units which may raise the cost of a furnace replacement in Merced.

Your customer service representative referenced a "No-Heat Call". What Is that?

A no-heat call is an industry term referring to a customer with a complete lack of heating power. This is one of the most common calls we get for heating repairs in Merced. Their furnace, boiler, or heater is producing no heat whatsoever for one reason or another. Because these scenarios can be uncomfortable, especially in Merced's cooler seasons, we prioritize these appointments on our schedules.

What should I do with my heating system if I’m going on a long trip?

It’s time for the vacation of a lifetime! Just you and the Outback for the next three weeks. No more annoying CA winter to deal with. During that time, the last thing you want to think about is your home’s heating system. Some people turn off their furnace or boiler before they leave, but this is the wrong approach. Allowing your home to get too cold could not only burst pipes but damage appliances, walls, and photos.

To both save on costs and protect your home, you’ll want to set your thermostat at around 55 degrees, a little warmer if you have pets. Just don’t forget to set your thermostat to ‘vacation’ or ‘hold’ before you dance your way out the door.

Why is one room cold and the other warm?

Is one of your bathrooms freezing and the other too hot? Heat inconsistencies like this are often the result of airflow problems. Blocked vents, improper heating system design, and leaky ductwork are often to blame. While you can try to DIY a fix like this, it’s often better to leave the fixing to an Merced HVAC specialist. Call (209) 723-4032 today and let Johnson Plumbing even things out.

What’s an AFUE rating?

First, this is an acronym that stands for Annual Fuel Utilization Efficiency. This rating tells you how effectively a water heater, furnace, or boiler converts its fuel into heat. The higher the number, the more efficient a heating system is. This number is reached by dividing the unit’s annual energy output by its input. The government sets acceptable minimum AFUE standards for equipment subject to periodic review and change.

What’s an efficiency rating?

The AFUE is one example of an efficiency rating. Other common ones include the seasonal energy efficiency ratio (SEER2), heating seasonal performance factor (HSPF2), and energy efficiency ratio (EER2). Regardless of what measurement is used, these ratings all have one job. They tell you how well a heating system heats a space and how much energy it uses.

Should I opt for an electric or gas heating system?

Which fuel source is best for your home depends on several factors. We’ll briefly compare the two fuel sources across a variety of characteristics:

Air Quality: Electric heating systems provide better air quality than their gas counterparts.
Safety: No flammables or gasses means less risk to your family.
Speed: Gas heaters generally reach temperature quicker.
Extreme Weather: If your power’s knocked out by winter weather, electric furnaces can’t function. Gas units can still provide warmth.
Lifespan: Electric furnaces in Merced last slightly longer than gas ones.
Maintenance: Gas furnaces require more maintenance overall.
Cost: Electric heaters are less expensive to install but cost more to operate.

Should I turn off vents in rooms I’m not heating?

A lot of homeowners think that closing off vents saves energy. But it doesn’t. In fact, this attempt at energy-saving can:

Cause undesirable pressure changes in your ductwork
Lessen overall heating system efficiency
Worsen existing air leaks
Aid mold growth due to misdirected warmth
Result in heat exchanger damage

Instead of shutting vents, open doors between rooms. If the issue is a room being too hot—and you haven’t zoned your home—you can slightly close the vent.

How do I tell what kind of heating system I have?

The easiest way to tell the difference is by looking at how the heat is delivered. You use a boiler if you have radiators and water pipes coming from your unit. If you have ducts or vents, your home in Merced is heated by a furnace or a heat pump. Do note that ductless heat pumps also exist. If you still aren’t sure, ask our Merced HVAC technician during your heating system tune-up. We'll let you know what your comfort depends on.

Is it bad to run my heating system at high temperatures?

Most modern furnaces can’t be set above 90 degrees. This safety measure protects the system by preventing long cycles and overheating. This protects vital components like the heat exchanger. Your heating system likely has a high-limit switch as an additional safety measure. If it detects the furnace's interior is too hot, it will shut the unit off. Most Merced HVAC experts recommend setting your thermostat no higher than 78 degrees.

What’s two-stage heating?

Single-stage heating systems, typically older or more economical, only have one level of heating output. While you can adjust the temperature on the thermostat, it doesn’t alter how hard the furnace works. To help boost efficiency, many modern furnaces are two-stage. This means they have a high and low output setting. The former is used on the coldest days to keep Jack Frost at bay. During more mild weather, the lower setting kicks in. These systems save energy and allow for more even heat distribution. Due to their flexibility, they’re also called modulating furnaces.

Why does my home get dry when my heating system runs?

Hotter air can hold more moisture than cold air. So, as it cycles through your home, heated air will pull water from the environment. The combustion process can also lower your home’s relative humidity. It should also be noted that winter is often characterized by dry air. Consider installing a whole house humidifier in Merced to make things more comfortable. These systems can be directly integrated with your furnace or other heating system.

What parts are there in a heating system?

Here’s a breakdown of the parts you’ll find in most heating systems in Heating Service:

Blower: This component pushes heated air from your furnace throughout the rest of the home. If this part breaks, you’ll notice the unit is on, but the vents aren’t active.
Blower Motor: The blower motor powers the fan in the blower. Without it, the air wouldn’t reach more than a foot or two from the unit.
Blower Chamber: That motor generates a lot of force and vibration. This box houses the two parts above and stabilizes them, stopping them from falling off course or rattling apart.
Combustion Chamber: This area of the furnace holds the entire firing system. For safety reasons, it’s separate from the blower chamber.
Heat Exchanger: This is one of the most important parts of a modern furnace. It’s how you get warm, safe air in your home. The gasses created by the ignition process are piped into the heat exchanger. The excess heat warms this part, transferring that energy to the air flowing outside the exchanger’s walls. Once drained of heat, the combustion gasses are sent out the flue pipe.
Burner: Every furnace needs fire to kickstart the heating process. Oxygen meets gas or an electric spark at the burner, and the resulting flame kickstarts the whole heating process.
Burner Cover: This small piece of metal covers the flame sensor, blower chamber, and ignitor. Its primary responsibility is keeping flames inside the furnace.
Flame Sensor: This part is small but mighty. It detects when the burner catches fire. Typically, it does nothing but wait. If there’s an issue with the burner, however, the sensor will shut the unit off, preventing deadly carbon monoxide leaks.
Ignition System: Older furnaces have pilot lights, which are always on and ready to start the system. Newer units—anything made after 2010—have an electronic ignitor. Unlike pilot lights, these systems can’t be blown out by a gust of wind, making them more fault-tolerant.
Limit Switch: This sensor reads the temperature inside your furnace. If the unit gets too hot, it’ll shut it off. You can typically find the limit switch under the supply plenum. You may hear it referred to as a fan limit or furnace high limit switch.
