Should You Replace Your Furnace with a Heat Pump?

Wednesday, February 4th, 2015

Furnaces are the most common type of heating system in the country, and by a pretty wide margin at that. There are many reasons for this popularity, including versatility and cost. However, being popular does not necessarily mean that a furnace is the best option for everybody. Heat pumps have been gaining in popularity among home owners for their energy efficiency and safer operation. So, should you replace your furnace with a heat pump? Let’s take a look at the pros and cons of each system and see if that can make your choice easier.

Furnaces

As mentioned above, furnaces are the most popular type of heating system largely because of their versatility and cost effectiveness. There are many different kinds of furnaces available, from electric to natural gas to wood, making it easier for homeowners to find one that fits their needs. Due to their widespread availability, furnaces are also relatively cheap to install and fix, compared to more rare systems.

The downside to furnaces is that they aren’t that energy efficient. A furnace burning natural gas, which is the most common fuel type for furnaces, tends to lose a lot of heat to various factors like duct leaks and combustion gases. Many furnaces still use standing pilot lights, as well, which constantly burn fuel in to stay lit. These cons lead to a lot of wasted energy and money.

Heat Pumps

Heat pumps are non-combustion heating systems. They don’t burn any kind of fuel to create heat, and only require electricity to run. They don’t use heating coils either, as electric furnaces do. Instead, a heat pump moves heat from one place to another by evaporating and condensing refrigerant. By siphoning heat from the outside air and releasing it inside, the heat pump saves a great deal of energy that would otherwise be spent on combusting fuel.

However, heat pumps do have one big drawback. In areas where the temperature frequently dips below zero, there is not as much thermal energy in the air for the heat pump to draw on. This leads to a decrease in the heat pump’s energy efficiency, as it has to work longer to heat the same amount of space.

If you aren’t sure whether or not to replace your furnace with a heat pump, call Red Rock Mechanical. We provide heating installation in the Williston, VT area.

This Is Why a Heater Must Be Properly Sized

Wednesday, January 21st, 2015

A lot of people think of heaters in terms of “bigger is better.” This is true, in the sense that larger heaters do have a greater heat output. It is not true, however, that a larger heater is always a better option. After all, if you follow that logic you end up with a commercial heater larger than your basement. In all seriousness, though, a heater absolutely must be properly sized to fit the home in which it is being installed. Let’s take a look at what can happen if you pick the wrong sized heater, either too large or too small.

Too Large

A heater that is too large tends to provoke one major problem, by putting out more heat than the rest of the system is used to. That major problem is short-cycling. Short-cycling is what happens when your heater rapidly turns itself on and off throughout the day. This is caused by the heater’s limit switch, which is designed to monitor the internal temperature of the heater. When the heater’s internal temperature gets above the safety limit, the limit switch shuts the system down to prevent it from overheating. After the heater cools off, it starts up again and provokes the same reaction. This locks the system into a never-ending cycle of on and off that wastes energy and damages the system. Now, the oversized heater isn’t actually overheating, but its heat output is high enough to provoke the limit switch anyway.

Too Small

A heater that is not large enough for the home it’s supposed to be heating will still have a much shorter lifespan, though not from short-cycling. Instead, an undersized heater will simply run indefinitely in an attempt to heat a space that it does not have the output to adequately service. The stress of constantly being on will wear down the heater much faster than one which is properly sized, eventually causing the system to die an early death and require replacement.

If you aren’t sure what size heater to install in your home, call Red Rock Mechanical and let us know. We offer quality heating installation in the Montpelier, VT area.

3 Ways to Improve Your Heating for the Rest of the Winter

Wednesday, January 7th, 2015

Everyone looks for ways to stretch their heating during the winter, both in terms of cost and effectiveness. While most people are content to simply keep doors and windows closed to keep as much heat in as possible, there are a number of better ways to ensure that your heating system is operating at peak efficiency. Let’s examine some of the best ways that you can improve your heating for the winter.

Schedule Preventive Maintenance

The best way to make sure that your heating system provides maximum heat output is to have it serviced at least once a year. The prime time to do this is usually during the fall, right before you start using the system more heavily. If you haven’t scheduled it yet this year, however, winter should do just fine. Having preventive maintenance done at this time of year ensures that your system is prepared for the stress of daily use during the winter, saving you the money and stress of repairing it when it breaks down.

Get Your Ducts Sealed

Forced air systems lose an incredible amount of heat each year to leaks in their homes’ ducts. The U.S. Department of Energy estimates this loss at about 30% of total heat, on average. This means that almost a third of the energy you paid for could be going to waste instead of heating your home. Since ducts are largely out of sight, and the leaks are often small, you probably won’t be able to find them yourself. Call a professional to examine and seal your ducts for you, and you’ll be able to significantly cut down on heat loss during the season you need it most.

Replace Your System

If your heating system is more than 15 years old, it’s probably a good time to consider replacing it. Even if you don’t have any mounting issues with the health of your old heating system, replacing it with a new one is almost guaranteed to increase the efficiency of your home’s heating.

If you’d like to know more about how to improve your heating, call Red Rock Mechanical. We provide professional heating services throughout Burlington, VT.

Common Problems You May Encounter with Your Heating

Wednesday, December 10th, 2014

Winter temperatures in Vermont may mean that we receive beautiful snowfalls, but they also mean that we must have durable heating systems in peak condition to keep us warm until the spring thaw. We have listed some common heating issues that you might encounter during the winter and what they may mean. If you think there is a malfunction with your heating system, don’t hesitate with calling for technicians. The problem will not improve and your heater may be in danger of a full breakdown…and that is the last thing you want to happen during one of the colder days of the year.

For fast and effective heating repair in Essex, VT and throughout Northwest Vermont, rely on the 24-hour emergency services of Red Rock Mechanical. We have served the area with quality comfort for over 23 years.

Frequent Home Heating Troubles

  • Insufficient heat: This problem can come from something as basic as a malfunctioning thermostat to a heating system that is too aged and worn down to work effectively. Call for a repair technician to determine what the trouble is and fix it or arrange for a replacement if that is the best option.
  • Weak airflow from the vents: If you have a furnace or heat pump in your home and you notice low levels of airflow coming from the vents, you should first check on the air filter to make sure it is not clogged with debris. If changing the air filter does not improve the airflow, you need to call on technicians to look for other possible causes.
  • Heater will not turn on: If your heater does not turn on when it should, the trouble could be a loss of communication with the thermostat. Another possibility is an electrical issue within the system, such as failed capacitors or electrical relays on motors.
  • Heater will not turn off: When a heater keeps running constantly, the likely culprit is an electrical failure that is preventing the blower from receiving the signal to turn off. Do not try to repair this problem on your own: it requires professionals.
  • Heating is too expensive: Should your heating bills begin to rise and you cannot explain why, then there is probably a malfunction in the heater that is making it overwork. Do not try to diagnose the cause on your own. Professional HVAC technicians can get to the bottom of the trouble fast and then handle the necessary repairs.

Whatever your concerns about home comfort during the winter, you can depend on Red Rock Mechanical for the heating repair in Essex, VT that will restore your indoor warmth. Call us any time.

Reasons Your Gas Furnace Might Not Be Running

Wednesday, December 3rd, 2014

There are many reasons why your furnace may not operate. The problem could be something fairly simple, or it could be something quite serious. This range of possibilities leaves a lot of room for mistakes, especially if you attempt to repair the problem yourself without having expert knowledge of your system. Vermont winters are no time to be without heat, even for a short duration, so if your furnace won’t turn on, call the people you can count on for heating repair in Essex, VT: Red Rock Mechanical.

Why Won’t My Furnace Run?

Here are a few examples of why your furnace may not be turning on:

Dirty Air Filter

When your furnace’s air filter becomes too clogged, it can restrict the air flow in your system. Proper air flow is necessary for your system to work, so if the air filter blocks air flow, the system can eventually shut down. It is recommended that you change your air filter every 3 months to avoid having problems develop.

Thermostat Issues

Your thermostat controls when your furnace turns on and off; if problems develop with your thermostat, your heater may not turn on. Common problems that can affect how a thermostat operates are frayed or corroded wiring, dirt and dust on the instrumentation and dead batteries. It’s also important to make sure your thermostat hasn’t been accidentally switched to off or cooling, or that the program hasn’t been altered if you own a programmable thermostat. If you own an older mercury-based thermostat, it may be to be calibrated.

Problems with Ignition

Furnaces have either a standing pilot light or electronic ignition. When a furnace has a standing pilot, it also has a safety mechanism called a thermocouple. This component lets the system know that there is a pilot and it is viable for ignition. However, if there are problems with the thermocouple, there can be problems with ignition. The same is true for electronic ignition. There are two types of electronic ignition: hot surface ignition and intermittent pilot. The probe for hot surface ignition can crack, disabling it from heating properly, and if the right amount of electricity doesn’t flow to the intermittent pilot, the pilot can’t be lit.

As you can see, a wide range of problems can cause your furnace to breakdown. Instead of trying to figure it out yourself, call the experts you can trust for all of your heating repair service needs: Red Rock Mechanical.

Reasons Your Heating May Become Inefficient This Winter

Wednesday, November 12th, 2014

We’ve got snow on the ground and it gets dark early – even though the winter solstice is next month, we’re clearly in our heating season here in Vermont. Trying to keep winter energy bills low is a challenge in our part of the country, so it’s good to be aware of how your heating system can become inefficient over the winter months. However, if you find that your system has become both inefficient and unable to heat your home as needed, it may be time to consider the installation of a new heating system in Stowe, VT. For over 23 years, Red Rock Mechanical has offered comprehensive heating services to Vermonters, so call us today!

Reasons for Inefficiency

Here are some of the more common reasons you may see reduced efficiency from your heating system:

Inadequate Maintenance

It is important that you schedule maintenance for your heating system annually. When your heater has to operate season after season, worn down and dirty from previous seasons, it affects the ability of your heater to work efficiently and effectively. During normal usage, components become dirty and dusty, and natural wear and tear can lead to corrosion. A maintenance appointment is a tune-up for your system, and allows your system to work optimally.

Ignoring Existing Problems

It can be tempting to ignore the signs of existing problems, especially if your heating system is still operable. However, repairs don’t fix themselves, and waiting to make repairs usually creates larger problems that can be even more costly. If you are aware of an existing problem, call for a technician and have it repaired before it creates stress and more potential problems for your system.

Age

The average lifespan for a combustion heating system is 15-20 years. Aging systems can struggle to meet the heating needs of your home, working harder to achieve the heating you need. When an aging system can no longer meet the needs of your home, it may be time to consider a replacement.

An inefficient heater can leave you uncomfortable and cost you money – something no one wants in the middle of a Vermont winter. If it’s time to consider a new heating installation in Stowe, VT, call Red Rock Mechanical today and schedule an appointment with one of our installation experts.

My Heat Pump Won’t Switch from Cooling Mode! What’s Wrong?

Wednesday, October 15th, 2014

The very last thing you want or expect when you turn your heater is for cold air to start venting into your house. In the case of heat pumps, this is an uncommon but frustrating problem. Fortunately, there is a fairly simple solution, though your HVAC technician will need to be the one to implement it. Before we explain what causes this problem, we have to understand how the heat pump switches between modes.

The Reversing Valve

Inside every heat pump is a part called a “reversing valve.” This valve sits at the junction of the central unit exhaust valve, intake valve, and both the indoor and outdoor unit lines. Inside this valve is a slide that controls which direction the refrigerant flows through the system. Depending on the direction, either the indoor or outdoor unit will blow hot air while the other blows cool air. This is what allows the heat pump to change modes.

Attached to the reversing valve is a solenoid, which operates an electro-magnet in the valve itself. The solenoid has two modes: “relaxed” and “energized.” All this really means is whether or not it has an electrical current running through it. When the solenoid is energized it activates an electromagnet which moves the slide from one position to the other and reverses the flow of refrigerant.

Common Problems with the Reversing Valve

Most often, the reason the heat pump gets stuck on one mode or the other is because the solenoid on the reversing valve is bad. If the solenoid is not working properly, it can’t move the slide from one side of the valve to the other. This essentially removes the heat pump’s ability to switch freely between heating and cooling modes.

So how can this be fixed? Often, the first thing an HVAC technician will do is check the solenoid for a magnetic charge. If it is displaying a charge, then something else might be responsible. Often, however, the solution is simply to replace the solenoid.

Call Red Rock Mechanical today if you are experiencing heat pump problems. Our comprehensive heating repair service cover the entire Montpelier, VT area.

What Ice along Your Heat Pump Might Mean

Wednesday, October 8th, 2014

It’s pretty common to walk outside during the winter and find ice on your heat pump. At first, it may seem like a problem you need to address. After all, you don’t want your heat source freezing over while it’s warming your house. In reality, however, you may not have to worry about it. Here is what ice along your heat pump usually means.

The Cause

A heat pump works by absorbing the thermal energy from the air around it. This thermal energy is then directed inside to heat and circulate air to the house. Condensation forms on the outside unit as a side effect of this thermal absorption. The sub-freezing environment then causes that condensation to freeze, forming frost on the outside of the heat pump.

The Solution

Heat pumps were designed to combat this condition by going through a defrost cycle every so often. A heat pump in heating mode will periodically reverse the flow of refrigerant, causing the outside unit to heat up and melt the frost around it. Therefore, there is no reason to worry about a little ice on your heat pump. If the heat pump is operating properly, it will take care of this issue on its own.

The Exception

There are cases where ice and frost can become a problem, however. If the defrost cycle doesn’t occur for whatever reason, ice will continue to build up around the outside unit. The more ice accumulates, the more air is cut off from the unit. This can drastically lessen the available thermal energy for the unit to absorb. If the ice and frost covers enough of the unit, it may stop absorbing heat altogether. If you happen to see ice on your heat pump, wait an hour or two and then check again. If the ice is gone or there is less of it, that’s a sign that your heat pump defrost cycle is working properly. If there is more ice or it doesn’t seem to be going away, you may have a problem with your heat pump. When that happens, call a professional.

If you are having issues with your heat pump, call Red Rock Mechanical. We service heat pumps and provide other professional heating services throughout the Stowe, VT area.

Why Heating Repair Is Not a “Do It Yourself” Job

Wednesday, September 24th, 2014

Do-it-yourself projects are much easier today than they once were thanks to the availability of instant access to resources such as free online tutorials. And while such projects may allow you to learn a valuable new skill, heating repair is not something that should be done without the help of a skilled technician. Technicians go through a lot of training to be able to recognize repair needs and make repairs quickly and accurately. That’s why it is important to call on a specialist any time you need repair, like the dependable folks at Red Rock Mechanical in Williston, VT. Let’s take a quick look at a few of the reasons you should always call a technician first whenever you need professional heating repair.

  • The problem may not be what you think. Many guides can give you ideas about what may be causing reduced heating or strange noises from your system. But a lot of problems have several possible causes, which is why you should always depend on a technician to help you diagnose the issue. Reduced heating, for example, may be a result of anything from duct leaks to a faulty motor to dirt on the furnace.
  • Technicians can finish the job more quickly. You want your heater up and running as soon as possible, and an experienced repair technician will probably get the job done much more quickly. This is because technicians go through a lot of training to be able to assess damage quickly and are equipped with the proper tools to get the job done.
  • A new heating system will be costly. Perhaps the most important reason to schedule heating repair is to avoid the need for costly system replacement. The opportunity to learn how to fix your heater is simply not worth the chances of a sudden breakdown.

At Red Rock Mechanical, we carry the proper certifications to handle any heating repair and offer a one-year warranty on our labor, something you definitely won’t get with home repairs. We also offer 24-hour emergency service, so you can get repairs at any time of day. For heating repair in Williston, VT, give us a call now!
