Ways to Save Money on Heating in Williston This Winter

Wednesday, October 29th, 2014

Energy efficiency is always a priority when it comes to heating during our cold Vermont winters. There are a number of small things you can do to help save energy this winter, as we’ve outlined below, but should you need repair, maintenance or installation of a heating system in Williston, VT, call the people you can count on: Red Rock Mechanical.

Energy-Saving Tips for the Winter

Here are some energy-saving tips that our Red Rock Mechanical technicians have put together:

  • Schedule an energy audit – an energy audit allows you to pinpoint exactly where your home is losing energy. Several tests are conducted during an energy audit, including a blower door test. All of the results from an energy audit are put together in a comprehensive report detailing any issues that are found, as well as recommendations on how to repair them.
  • Cover drafty windows – there are a couple of ways to effectively cover drafty windows, such as using a plastic window coverings or winter drapes. Plastic kits are easy to use, widely available and work for any standard-sized windows. The plastic is clear, so you can still see outside without a problem. Winter drapes are usually made of heavy material that helps block drafts, and are available in many retail outlets.
  • Set EPA-recommended temperatures – EPA thermostat recommendations are that an occupied home shouldn’t have the thermostat set any higher than 68 degrees, and, when your home is unoccupied, the temperature should be set 10-15 degrees lower. Following these recommendations can help you save as much as 10% each year in heating costs.
  • Install a programmable thermostat – programmable thermostats allow you to set a program of temperatures for different times of day, different days of the week and even vacation time. This gives you great control over your heating during the winter.
  • Schedule annual maintenance – annual maintenance provides a thorough tune-up for your entire system, as well as the cleaning of components. This allows your system to run at the energy efficiency level it ought to.

Winter energy costs are a large part of your household budget. By utilizing some of the tips above, you can reduce some of your heating costs in Williston, VT this year. Need some additional help? Call Red Rock Mechanical today and schedule an appointment with one of our 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.

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!

Why You Should Get a Cold Climate Heat Pump

Friday, April 25th, 2014

Heat pumps are a form of air conditioning system, designed to both warm your home in the winter and cool it in the summer. They are popular in warmer climates because they’re much more efficient than other forms of heating, and they combine the functions of a heater and an air conditioner into one. They do have one large downside, however. When the temperature drops below 40 degrees Fahrenheit, their efficiency drops along with it. Here in Vermont, heat pump technology is looked down upon for that reason. A heater that doesn’t work well in very cold temperatures won’t last long up here. Even so, heat pumps offer a number of benefits to those of us in the Northeast. Here’s a few reasons why you should get a cold climate heat pump.

Heat pumps don’t actually create heat on their own. They simply facilitate a heat exchange with the refrigerant in their system. That means they don’t us gas or other fuel (besides a little electricity to run), and they don’t create any toxic gases the way furnace and other types of heating do. That makes them environmentally friendly, as well as efficient and reliable. We like keep our state green and heat pumps do a lot to help on that front.

But that still doesn’t get around the problem of working on cold days, of which we have plenty. In a number of cases, however, you can marry a heat pump to a smaller electric furnace in a hybrid unit. When the temperature drops, the furnace kicks in, giving the heat pump that extra boost it needs to keep you warm effectively. And because the furnace is so small, you’re still saving money over a forced-air furnace or boiler, while retaining the other benefits that a heat pump offers.

Here in Vermont, heat pump technology can be a viable option, and the experts at Red Rock Mechanical are here to help. We can explain why you should get a cold climate heat pump, then help you find the right system for you. Give us a call today and let us show you what we’re capable of!

What Makes a Furnace High Efficiency?

Monday, March 31st, 2014

In a lot of ways “high efficiency” is in the eye of the beholder. Luckily, you don’t have to depend on subjective opinion to understand what makes a furnace high efficiency. Here in Burlington, VT, heating is no laughing matter and a high efficiency unit can mean big savings during the cold winter months. But who determines what constitutes high efficiency? That is, how can you tell that a “high efficiency” furnace actually is what it claims to be, and not just empty rhetoric from some advertiser somewhere?

The answer starts with the AFUE (Annual Fuel Utilization Efficiency) rating, which all furnaces must possess. It measures the percentage of the energy a furnace uses that actually goes into heating your home. So a furnace with an AFUE rating of 80% would spend 80% of its energy on heating and 20% on waste and inefficiency. Obviously, the higher the rating, the more efficient the furnace, which is where the subjectivity comes in. If you spend 20 years using a furnace with an AFUE rating of 60% and install a new one with an AFUE rating of 75%, it’s going to seem very efficient indeed.

The U.S. Department of Energy has established formal criteria for furnace efficiency. The EnergyStar sticker is used to denote furnaces that are particularly energy efficient: with a 95% AFUE rating or higher for gas furnaces, and an 85% AFUE rating or higher for oil furnaces. (That number drops slightly for gas furnaces in warmer parts of the country.) The EnergyStar rating helps eliminate the uncertainty in the equation and let you choose an efficient heater no matter what the circumstances.

For more on what makes a furnace high efficiency, or for installation options, you can call upon Red Rock Mechanical for help. We stand by our assessments with an ironclad guarantee, and we won’t rest until you are completely satisfied with our work. Here in Burlington, VT, heating systems need to be as efficient as possible. Contact one of our trained technicians today and let us help you make that happen!

Signs of a Furnace Control Board Problem

Thursday, March 20th, 2014

The modern furnace is a marvel of technology, especially when compared to the furnaces of yore, which were basically large ovens with pipes hooked up to them. Contemporary furnaces have most of their operations linked into a furnace control board, which is the core of how the furnace works. The control board runs a series of operations—starting the electronic ignition, opening the gas valve, checking the burner unit, activating the blower, shutting off the gas, venting the heat exchanger—that moves the furnace through all the stages of providing you with heat.

The control board can malfunction, however, and put your furnace’s operation in jeopardy. When this occurs, you will need to call for professional heating service in Williston, VT to replace the defective board. Red Rock Mechanical can provide this service for you, fast and effectively, when you need it.

Here are signs you may have a malfunctioning furnace control board:

  • Uncomfortable temperatures: If your furnace starts to make you either too hot or too cold, and the thermostat settings seem fine, then the problem might be a control board that is turning components off too soon or letting them run too long. Although there are multiple issues that can cause this malfunction, the control board is one of the main culprits.
  • Interruption of the regular sequence of events: Elaborating on the above warning, pay attention to your furnace’s specific sequence of operation. (Don’t open the furnace cabinet to check, just stay near it and listen to what happens.) Does the blower stage stop suddenly? Are the gas jets not activating? Is the ignition not coming on? Does the blower continue to run after everything else has shut off? Any of these irregularities in the normal sequence of events can indicate control board malfunctions.
  • Diagnostic indicators: Most boards have LED lights to indicate when there is a problem with their operation. If your furnace starts to run improperly, open up the control board access panel to see if any red warning lights have activated. There should be a diagnostic chart on the inside of the panel lid that will explain what the warning lights mean. When you call a technician, describe the diagnostic information so the technician will have a good idea what problem needs to be addressed before coming to your house.

It takes a fine knowledge of electronics and furnace technology to replace a control board. Don’t attempt to fiddle around with the panel on your own without the proper training. Make a call to heating experts with as much information as you can glean from the panel to explain the situation. They can take it from there.

Red Rock Mechanical has helped people in Williston, VT with heating services for 23 years. If you need work done on your furnace’s control board, give us a call.

Some Problems You May Encounter with Your Gas Furnace

Thursday, March 13th, 2014

In Montpelier, VT, furnaces are common in many homes. Gas furnaces are inexpensive to operate and very reliable, but like any mechanical system, they will experience breakdowns from time to time. You can call a reliable repair service to resolve the problem, but it helps to spot the signs of those problems as soon as possible, before they lead to more serious issues. Here’s a quick breakdown of some problems you may encounter with your gas furnace.

  • Lack of gas flow. The thermocouple, connected to your ignition system, controls the flow of gas into the heater. If there’s a problem with your ignition system, or indeed with the thermocouple itself, the gas will be shut off (preventing your home from being flooded with the gas but also rendering the heater non-functional until it is fixed). A clogged burner can also disrupt the gas flow, as can problems with the line feeding the gas into the furnace.
  • Lack of heat. A lack of heat usually comes back to a problem with the burners, which push the lit gas through the heat exchanger to warm the air that is ultimately blown into your home. Burners can suffer from a malfunction, and could also become clogged with grime on their surface, which will reduce the levels of heat they generate.
  • Lack of air flow. Low air flow is just as bad as reduced heat, since it forces your furnace to work harder and expend more energy than it should. Low air flow can stem from a faulty motor, a damaged blower fan, or some kind of obstruction in the duct system reducing the space in which the air can move.

The problems you may encounter with your gas furnace don’t matter as much as the service you call upon to correct them. If you need furnace repair in Montpelier, VT, call Red Rock Mechanical today.

3 Signs You Need to Schedule Heating Repair in Burlington, VT

Tuesday, March 4th, 2014

In Burlington VT, heating problems need to be fixed quickly. A day without a functioning heating system means more than bother and inconvenience: it may constitute an actual safety risk to your family. A good heating company can respond right away, but it helps if you can spot the signs of trouble sooner rather than later. That will let you get ahead of the problem and take care of it before it shuts down your heater for good. Here are three signs that you need to schedule heating repair in Burlington VT.

  • No air flow or reduced air flow. This category also includes instances where your heater refuses to turn on at all. If air flow is lowered, it reduces your heater’s ability to warm your home. If it’s stopped completely, no heat will go into your home. The cause could range from a clogged filter to a damaged fan motor, but usually needs professional attention to fix.
  • No heat. Similarly, your heater may be moving the air just fine, but heat levels may be lowered or nonexistent. This usually means a problem with the burners or heating coils, though it could also stem from a blockage at some point in the system.
  • Higher bills. Sometimes, there’s nothing specifically wrong with the system, but lack of efficiency and/or worn parts are preventing it from functioning at its best. You can usually spot these problems by monitoring your monthly bills. If your heating costs spike despite the fact that you’re not using your heater any more often than normal, you’re probably looking at a faulty or worn component that could use repairing or replacing.

If you spot the signs you need to schedule heating repair in Burlington, VT, the next step is to call the experts at Red Rock Mechanical for help. We’ve been a mainstay of the area for over two decades, and we take pride in complete satisfaction for our customers. If your heater is showing signs of distress, don’t hesitate.

Why is My Furnace Blowing Cold Air?

Tuesday, February 25th, 2014

Here in Stowe, VT, heating is a serious concern, and a disruption in service can spell serious problems for your household. “Why is my furnace blowing cold air?” isn’t a question you ever want to contemplate in the depths of winter. As much as we may wish otherwise, such incidents do happen, and when they do you need a first-rate repair services for correct the problem with speed and efficiency. If helps if you understand the process involved in creating the situation. A number of different factors can lead to your furnace blowing cold air.

In some cases, the issue stems from a simple setting with the thermostat. It may be set too low or located in a spot in the house that’s warmer than elsewhere.  Your furnace itself may also contain a faulty component, turning the fan on without igniting the burners or releasing the gas. A repair technician can repair or replace the thermostat, or move it if it needs to be in a different spot, or troubleshoot the sequence of your furnace.

Other problems stem from a lack of fuel, or from the fuel not igniting properly. If you have an older furnace with a pilot light and the light goes out, it won’t produce any hot air. In some cases, clogs or blockages can result in cool air blowing from the furnace as well. For example, if the condensate system is suffering problems, such as the line being clogged with dirt or the reservoir float being closed, then the gas won’t be allowed into the system even if the fans are blowing.

Whatever the cause, it takes a trained professional to determine the source of the problem and correct it. In Stowe, VT, heating repairs can be conducted by the experts at Red Rock Mechanical. We can answer the question “why is my furnace blowing cold air?” then correct the problem with efficiency and care. Give us a call today to make an appointment, and let us show you what we can do!
