Why is My Furnace Turning On and Off? A Question from East Brunswick

Wednesday, November 9th, 2011

One of the most annoying things your furnace can do is to constantly keep turning on and off. This on-off cycling keeps your East Brunswick home from heating up properly. This action – called short cycling – also requires more electricity and drives up utility bills.

Short cycling is caused by an overheated furnace, which triggers safety mechanisms and shuts down the furnace. After a brief interval and cooling down, the furnace starts up again the cycle keeps repeating itself. Not only is it an annoyance, it can also signal more serious problems. A leaking heat exchanger can cause a furnace to overheat – and produce deadly carbon monoxide gas.

If a furnace is working too hard and overheating, it is usually because of airflow in and out. Your home’s ventilation system needs to be clear of dirt, dust, and debris. The more blockage in your ductwork and vents, the more friction is created, slowing down airflow and ultimately ending with an overworked furnace that continues to cycle on and off. And a blocked exhaust vent, such as a chimney or dedicated exhaust vent, can also cause a furnace to work harder. Check for things like leaves or bird’s nests.

The blockage may also be coming from a clogged furnace filter. You should clean or replace your furnace filter after a visual inspection reveals any type of build-up of dust or dirt. Do this at least every three-six months.

If you have a two-speed fan on your furnace, it is recommended that you run the fan in low speed during the cold months and high speed in the warm months. The reason? Warm air is lighter and takes less force to move.

There are other measures to take to prevent short cycling but these usually require a professional heating and cooling service technician to correct the problem. If in doubt, call your local qualified heating and cooling contractor and schedule a furnace inspection. Don’t make your furnace work any harder than it was designed for – and keep your home’s occupants comfortable and safe.

Air Source Heat Pumps (and Happy Halloween Weekend!)

Friday, October 28th, 2011

Everyone at Heritage Home Services wishes you a Happy Halloween Weekend! Have a great time as a ghost, a goblin, or anything in between! And to keep your house warm after you are done trick or treating, today we have some information about heat pumps for you.

Most heating systems have as their main component some sort of heat generator, such as a furnace or boiler. These machines generate heat through some form of combustion, which obviously converts energy directly to heat, which is then distributed throughout the home. That’s a pretty simplified schematic explanation, but that’s more or less how most heating systems work.

Air source heat pumps are another type of heating solution; one that does not actually produce or generate any actual heat. There is no combustion. What an air source heat pump (ASHP) does instead is regulate the temperature of the home by essentially moving air around.

An air source heat pump use electricity to exchange indoor and outdoor air. Think of it like a more versatile air conditioner. In cooling mode, like an air conditioner, an ASHP will pump warm air from the inside out, using a system of refrigerant-filled coils and a compressor. By turning the ASHP to heating mode, the refrigerant flow is reversed, allowing the outdoor coils to extract heat from the outdoor air and pump it in higher concentrations to the inside.

If it seems like a simple system, that’s because it is. All the heat pump does is move heat either in or out, depending on what you need in the current season. Because this process generates no heat on its own, heat pumps can be very efficient. ASHP efficiency has been estimated at 150% to 300%, meaning that the heat energy produced is up to three times as much as the electricity used. That makes for a very efficient home heating and cooling solution.

Air source heat pumps are not necessarily right for every situation, however. In colder climates, where temperatures drop below 30 degrees Fahrenheit for stretches at a time, a heat pump will likely not be able to keep up on its own. In these situations, you may either need to supplement the ASHP with an additional heating source, or use a different system altogether. Newer so-called “cold climate” heat pumps may also be an option. Under ideal circumstances, an air source heat pump can act as a complete home heating system, as well as providing heat for hot water.

If you are looking for a simple and efficient home heating solution, look into whether an air source heat pump can work for you.

Your HVAC System and the Gas Line: Some Pointers From Manasquan

Wednesday, August 24th, 2011

What happens if you lose your gas line? What relationship does that simple copper pipe have to the comfort control of your Manasquan home? It depends largely on the scope of your HVAC system and what time of the year you lose gas, but the answer is almost always that it will have a pretty big impact.

What Uses Gas in Your Home?

There are a number of components that use gas in your home. The first and most common is your furnace, but you will find that your water heater may also use a gas line and some packaged air conditioning systems use gas for heating components.

  • Heating – If you have a gas line, it’s very likely that your heating system uses gas as an energy source. It’s the least expensive of the three major energy sources (oil, gas and electricity) and gas furnaces and boilers are extremely efficient. In terms of how much gas you will use, one cubic foot of gas contains 1040 BTUs of heating energy per hour. So, if your furnace offers 100,000 BTUs of heating capacity, it would use 96.15 cubic feet of natural gas when running at full capacity. Keep in mind, though, that a gas furnace is rated with an AFUE rating. This is the percentage of the fuel consumed that is actually converted to heat. So, if your AFUE rating is 90%, your actual BTU production would be 90,000 for the same 96.15 cubic feet of gas. The cost of natural gas varies by location, but is generally around $1 per cubic foot.
  • Boilers are very similar in their gas consumption rates. Boilers are rated for maximum output – so if you have a 15kW boiler – meaning it will burn the equivalent of 15 kWh of gas per hour when running at full capacity. Keep in mind that this is the maximum output. If you only have one radiator open, the actual rate may be much lower.
  • Water Heating – For a water heater, gas rates are charged by kWh, just like your boiler. The total is usually significantly less than for a boiler, but the same mechanics apply. Your water heater should have a placard or sheet that lists its maximum production per hour so you can determine how much gas it uses per hour when your hot water is in high demand.

Gas is a highly volatile substance and while there are a number of safety measures implemented in your home to protect your family, it’s important to ensure the gas lines are well maintained. Annual maintenance is a must to keep the gas working properly. If you do notice a leak or sudden loss of gas, don’t call a contractor – call the gas company immediately as it could be an emergency.

Energy Recovery Ventilator – What Is It and When Do You Need It?

Friday, June 24th, 2011

It isn’t cheap to heat and cool the air you circulate through your home every day. In fact, heating and cooling can be the most expensive energy related systems you operate. So, the last thing you want is to open a window and pour all of that conditioned air into the great outdoors.

That’s why most modern homes are sealed up so tightly. The heated and cooled air you enjoy so much needs to be retained, both to save money and to reduce your energy use. It’s why the government offers credits for things like insulation upgrades and the purchase of more energy efficient comfort systems.

But, while sealing everything saves you money and reduces your energy use, it can negatively impact your indoor air quality. Without proper circulation and ventilation, the air in your home grows thick with indoor contaminants like pet dander, pollen, dust, and possibly even bacteria or gasses. Normally, these things would be circulated outside through traditional ventilation. But, because of your heating and cooling system, the age old method of cracking a window to let a little fresh air in just doesn’t work anymore.

An energy recovery ventilator solves this problem. Instead of just pouring heated or cooled air outside and replacing it with fresh air, an energy recovery ventilator passes the air through a series of chambers. Within those chambers the heat is transferred from the warmer air to the cooler air.

In the winter, this means the indoor air passes its energy to the incoming air, retaining the heat your furnace or boiler generated. In the summer, the air coming in from outside passes its heat energy to the cooled indoor air as it leaves and only cool air enters your home.

In effect, an energy recovery ventilator works to reduce the cost of both heating and cooling. It is true that most indoor air quality systems are designed to remove many of the contaminants you flush outside, but relying solely on your air purifier or filter puts undue stress on the equipment. Not only will you need to replace filters and cartridges more often, you may need to replace the entire system earlier than you would otherwise. If you’re tired of losing all that conditioned air just to get a fresh breath, look into these amazing machines for your indoor air system.

2011 AC Federal Tax Credits

Friday, June 17th, 2011

You’ve probably heard many arguments for why you should purchase an energy efficient air conditioner. They may cost a bit more up front, but they’ll save you money in the long run by cutting down on your monthly energy bills. They’re also better for the environment because their lower energy usage means less fossil fuels are burned to keep them running.

But there’s another reason energy efficient AC units are better buys than your standard alternative. There are Federal tax credits available to consumers who purchase them. This tax credit can more than make up for the higher purchase price of the units, allowing you to enjoy your monthly savings much sooner and know you’re doing your part to protect the environment.

How to Qualify

In order to qualify for 2011 air conditioning Federal tax credit, you need to purchase an appropriate energy efficient AC system. Your HVAC contractor or salesperson can tell you which models and units qualify for this program. Just make sure you save all documentation and proof of purchase in case you need them to validate your claim.

The AC units that qualify you for this tax credit include those with a SEER (seasonal energy efficiency ratio) of 16 or greater and an EER (energy efficiency ratio) of at least 13. These two numbers are the best and clearest indicators of the overall energy efficiency of the product and can easily be found on the packaging for any air conditioning unit. While a 16 SEER is very good, it is not the highest rating currently available, either, so you won’t be forced to buy the most expensive model available to get your credit.

Credit Details

The tax credit is good for up to 10% of the purchase price of the unit up to $300. Keep in mind, though, that you can only claim up to $500 lifetime towards this program. So if you’ve previously claimed $250, you can only claim an additional $250 for 2011. That’s still a significant savings, though, and well worth looking into if you’re in the market for a new AC unit or system.

So if you’ve been thinking about upgrading your AC system, but haven’t quiet gotten around to, now may be the time to take advantage of this great tax credit opportunity before it’s too late.

Air Conditioners and Energy Use by Percentage

Wednesday, May 25th, 2011

It’s no secret that air conditioners use up a lot of electricity and can add substantially to your energy bills during those warm summer months. But did you know that they actually account for an estimated 11% of the total energy used in all buildings in the US each year? This is a staggering figure and makes it easy to see why it’s best to invest in the most energy efficient system possible.

Keeping Your Consumption Down

There are plenty of reasons to try and keep your energy consumption down. You want to save on your energy bills, and the less energy you use, the better it is for the environment. The best and most straightforward way to go about this is to purchase only highly energy efficient appliances and equipment, and that includes air conditioners.

Because air conditioner usage accounts for such a substantial part of the total energy used in this country, putting more energy efficiency models into use is the best way to cut that usage down.

Supplementary Cooling

However, there are other ways to reduce the workload of your air conditioner. For instance, you can use a ceiling fan to maintain good air circulation and keep your home cool. Using a ceiling fan with an air conditioner, even on the hottest days of the year, allows you to turn up your thermostat a bit to conserve energy while still enjoying a comfortable indoor environment. And because ceiling fans use so little energy to operate, you’ll come out ahead on your energy bill.

Passive Cooling

There are also several passive cooling methods you can employ to keep the temperature in your home down. Blocking out sunlight is the most important of these, so keep your blinds closed on any windows that receive direct sunlight, particularly in the early afternoon. Alternately, you can have awnings put up, which allow you to block the direct sun while still keeping the blinds open.

Shade is another effective passive cooling device. Planting trees around your home to block out the sun at the hottest times of day is a totally energy-free way of keeping your home cool and reducing the workload on your air conditioning system. The less your air conditioner has to work, the less energy it consumes and the lower your energy bills will be.
