Cincinnati HVAC Tip: How to Maintain High Efficiency Filters to Reduce Stress on Your Heat Pump

March 26th, 2012

The filter on your heat pump is an integral part of your Cincinnati air conditioning and heating system. Without that filter, the device will quickly be subjected to an influx of debris and contaminants that can get into the machinery and the air being filtered into your home. As a result, you need to make sure you properly maintain the filters to reduce stress on your heat pump.

Cincinnati Heat Pump FilterChange Your Filters

We all know that high efficiency filters are great to have in your home because they remove contaminants from the air. This keeps your indoor air clean and healthy by preventing pollutants from circulating throughout your forced air system. But what most people don’t know is that if you don’t maintain your air filters, they can actually cause your Cincinnati heat pump to work much harder.

When high-efficiency filters get clogged, they can restrict airflow and cause stress to your heat pump. Not to mention making your indoor air quality worse! The contaminants that were caught by the air filter might now start getting back into the air supply, which can have a big impact on your indoor air quality. It is easy to see why it is so important to change your air filter regularly, especially if they are high efficiency.

 Recommended Filters

You have options as to which types of filters you use for your heat pump. Filters come in multiple options, from super high MERV rated filters that trap up to 99% of all contaminants as small as 0.3 microns.

Electrostatic filters are especially efficient because they extract contaminants of all types – from dust and mold to smoke and gas fumes. A good filtration system should effectively remove anything from the air without needing replacement too often.

Permanent filters tend to offer the best protection against airborne contaminants and generally need to be cleaned once a month. HEPA filters are often permanent and while each filter is different, these are often extremely effective at minimizing contaminants in the air without putting stress on your Cincinnati heat pump.

Withamsville Heating Question: What is an Air Source Heat Pump?

March 21st, 2012

Most heating systems in Withamsville 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 Withamsville 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.

Cincinnati Heat Pump

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 Withamsville heating solution, call RineAir Heating & Air Conditioning to find out whether an air source heat pump can work for you.

Cincinnati HVAC Tip: What Do You Have to Learn to Be an Qualified HVAC Technician

March 14th, 2012

No matter how the style, usage and materials change in buildings, there will always be the need in Cincinnati to heat the spaces comfortably in winter and cool them affordably in the hot days of summer.  The wide variety and complication of systems requires certain knowledge to maintain and install them.

If you’re looking for a dependable and lucrative career, being an HVAC technician makes good dollars and sense.  As either a self-employed contractor or as part of a larger company, the business of heating, venting and air-conditioning homes, businesses and institutions is sure to be always available.

Areas of Focus

Depending on the interests of the individual, there are various ways to be involved with HVAC systems.  Some choose to participate only in the initial stages of designing, estimating and selling systems to the customer.  Others focus on the installation while still others are only involved with the regular maintenance and service of existing systems.

An independent sub-contractor may need to be expert in all areas of HVAC systems where a team of technicians can concentrate on their selected interests.

The Road to Certification

HVAC refers to many different kinds of systems powered by numerous different types of energy.  Improvements in the technology create an ever changing fast paced body of required knowledge.  Experience is the best teacher but cannot alone keep technicians up to date.

Most certification programs are based on three to four year apprenticeships combining on the job training with classroom lessons. In community colleges and vocational tech schools, a shorter period is required, only two years for an associate degree that teaches the basics of repair and maintenance as well as installation.

No matter which way you choose, final certification is given by either the North American Technician Excellence program or the Air Conditioning Excellence Coalition.  With an official certification in the HVAC field, prospects for better employment and higher wages are nearly guaranteed.

What to Learn

HVAC systems are very technical and full of details.  Installation and maintenance of the systems requires many skills, including working with different kinds of piping, motors, pumps, compressors, ductwork, screens and filters.  You learn the difference between boilers and furnaces, refrigerators, coolers and air-conditioners. There is so much variety and detail to learn that many individuals choose to focus primarily one or several areas instead of trying to be fully expert about all parts.

Cherry Grove HVAC Tip: Surprising Sources of Indoor Air Pollution

March 7th, 2012

Indoor air pollution is a major problem for millions of homeowners throughout the country each year. In fact, the EPA estimates upwards of 20 million households may have problems caused by mold, radon, humidity, exhaust or any number of other pollutant problems. However, not all of the indoor air pollutants out there are so obvious. Some are things you probably have in your Cherry Grove home right now and don’t realize it. Here are some of the more surprising sources of indoor air pollution and what you can do about them:

  • Incense – Incense releases both carbon monoxide and benzene, two chemicals that are potentially harmful to human health. Cancer, skin irritation and asthma risks are all increased in people who spend a lot of time around incense.
  • Laser printers – Laser printers that use toner can release a number of harmful chemicals into the air. That toner is very fine and releases particles into the air that are equal to or in some cases worse than second hand cigarette smoke. If you have a laser printer, consider putting it in a well-ventilated, infrequently used space.
  • Kitchen Stove – If you have a gas stove, it releases Nitrogen Dioxide when on, an unsafe gas that is odorless and fills your home quickly. This gas is bad for respiration and can cause asthma attacks. To solve this problem, simply make sure you stove is ventilated properly when cooking.
  • Spackle – Old spackle – the kind used before the 1980s often contained asbestos which can still be there, waiting to be disturbed. Old asbestos, while not inherently dangerous, will become so if you start doing work in your home or if the spackle starts to wear away. To solve this problem either call an abatement firm or cover the offending wall with a new layer.
  • Drapes – Those drapes are filled with contaminants that cling there, especially if humidity is a problem in your home. Dust mites in particular are bad for your health and can cause asthma and other allergies. Blinds are better than drapes for this reason.

Your home is filled with potentially dangerous problems, but you can avoid them simply by taking care to ventilate, clear away unsafe products and keep things like drapes clean (or remove them). If you’re still concerned about your air quality, call RineAir Heating & Air Conditioning to investigate.

Cincinnati Geothermal Installation Question: Is Geothermal for Me?

February 29th, 2012

Geothermal heating is a great alternative to other types of home heating systems in Cincinnati. It is safe and efficient, costs very little to operate and makes use of a great renewable resource right below our feet. But is it right for you? Well, geothermal heating may be the right choice for many people, but there are many things to take into account before you can determine whether or not it is the best choice for your home.

The first important thing to understand when you are trying to decide whether or not to go with geothermal heating is how one of these systems actually works. A geothermal system heats your home by extracting heat from the ground and then transferring that heat into your indoor air. This happens when liquid, usually water or antifreeze, passes through a loop of pipes installed several feet below the ground.

The liquid absorbs heat from the ground, which in the winter is always warmer than the air, and carries is back up to an air handler inside your home where that heat is allowed to disperse into the air. Once the air is heated, the air handler blows the air through a system of ducts throughout your house, providing a constant stream of heated air to all areas of your home. The liquid, on the other hand, simply cycles back through the ground loop to pick up more heat and repeat the same cycle over again.

Because a geothermal heating system does not actually generate heat, it requires very little energy to operate. This means that it is both very cheap for you to run and environmentally friendly. But since installing a geothermal heating system involves putting pipes in underground, it can be pretty expensive initially. However, as long as the amount you save every month on your heating costs is enough to offset the high initial price of installation, it is worth it to put down the money up front.

Another alternative, of course, is a more traditional air source heat pump. These are much cheaper to install and nearly as cheap to run. However, air source heat pumps are not as efficient when the air temperature gets below freezing as a geothermal system can be. If you live in an area with harsh winters, the geothermal heat pump is a better option than an air source unit.

Landen Heat Pump Question: What Happens if My Heat Pump Loses Power?

February 24th, 2012

One of the advantages of having a heat pump in your Landen home is that they operate on electricity, so you don’t need to worry about having maintaining a supply of fuel to keep it running. Where a furnace or boiler might call for you to purchase supplies of oil or natural gas, and a wood stove means keeping potentially messy firewood around, a heat pump runs cleanly on electricity.

Heat pumps are good at using electricity, too. They are often able to produce heat energy that can be as much as three times the electricity they draw to produce it. This means not just convenience, but also a big savings, just by virtue of using electrical power.

The risk there, of course, is that if and when the power goes out, so does the heat pump. That means when a big winter storm drops a tree on the local power line, things can get cold inside mighty quickly. For these situations, you should have a backup heating solution on hand to keep everyone comfortable in the short term. And, as a responsible homeowner, you likely already have this taken care of.

But what happens when the power comes back on? Can you just fire your heat pump right back up without missing a beat?

The short answer is “no.” You should not do that, for at least two reasons. First of all, after any power outage, you should always take care to turn on appliances gradually over a period of time rather than all at once in order to avoid a spike in demand at the power company, which can blow a grid. That’s just a general tip.

Specific to heat pumps, though, there is a unique concern. If the heat pump loses power for more than 30 minutes, the refrigerant can get too cold to flow properly, so turning it right back on can cause the whole thing to conk right out. Instead, do the following:

  1. Make sure the heat pump is off. You can do this during the power outage.
  2. Once power comes back on, turn the heat pump to the “Emergency Heat” setting. This will allow the compressor to warm up slowly and get the refrigerant warm enough to start flow freely again.
  3. Wait. The time you need to wait varies depending on the size and manufacturer of your heat pump, so refer to the manual. In general, you should wait at least 6 hours.

After this process, your heat pump should be ready to resume normal operation without issue. If you run into any problems, give RineAir Heating and Air Conditioning a call right away!

 

Norwood Geothermal Installation Question: How is Geothermal Different than Other Heating Systems?

February 22nd, 2012

There are many methods to heating a building in Norwood. Early methods included burning coal and wood. Today, sophisticated building controls call for more efficient means of heat – and a method gaining in popularity is geothermal heating.

Many use air handling units to deliver heat – and that method has remained constant over the years. But air handling units are only designed to move air from one space to another. How that air is heated from the source is what differentiates geothermal from other energy sources.

To understand some of the differences, let’s look at the definition of geothermal heat. By definition, geothermal heating comes from its direct use of geothermal energy, which comes from below the Earth’s surface. And the Earth is known as the greatest conductor of heat. The constant, renewable temperature of the Earth (56-58 degrees on average below 10 feet) provides a heat source requiring no energy conversion, which adds to heating efficiency and ultimately, the cost to heat a building.

In order to heat a building, natural heat from the ground absorbs a colder refrigerant, which is circulated throughout the ground by a series of polyethelene tubing, which is generally positioned five to ten feet below the surface. This heat is transported via the refrigerant to a compressor inside a heat pump, where it is compressed and the lower temperatures are transformed from around 50 degrees to temperatures much higher, as high as 100 degrees of more. This hotter refrigerant is circulated through the tubing within an air handling unit, where colder return interior air absorbs the heat. The heated air is then carried to a building’s interior via fans. The refrigerant, with the heat removed, now becomes colder as is re-circulated into the ground to absorb the natural, renewable heat. In essence, the ground provides free heat.

Other methods of heating include forced air natural gas, oil, solar, propane, electric, radiant, and steam. Each heat source requires mechanical means to heat up the supply air. For example, natural gas – which is used to heat about half of all U.S. homes – is heated via a heat exchanger in a mechanical furnace, which runs on electricity. Radiant or steam heat is generated by mechanically raising the temperature of water or refrigerant via electricity. These methods differ from geothermal because the natural heat of the Earth provides the means for raising the temperature of the refrigerant used to transport heat to the air handling unit.

One drawback to using geothermal heat compared to other energy sources is the cost to bring this natural heating method into a building. The initial installation of a geothermal heating system is much higher than conventional natural gas heating – for example – because of the cost to install the tubing called a ground loop beneath the Earth’s surface. No other heat source, other than radiant heat, requires a series of tubing to deliver heat. But then again, radiant heat does not require a ductwork system to transport heated air or remove colder air. Geothermal requires a series of metals tubes to heat the refrigerant and the ductwork to move the heated air throughout the building.

On the flip side, its energy efficiency – using the Earth’s natural heat – is much greater than other heating sources resulting in lower utility costs, often fractions of the cost to use other heat sources. Energy savings could pay for the cost of installing the geothermal system over several years – another characteristic of geothermal heating.

Fort Thomas Heat Pump Repair Question: Why Won’t My Heat Pump Start?

February 17th, 2012

If you are having trouble with your Fort Thomas home’s heat pump, you may be surprised to learn that it is probably not the heat pump that is to blame, especially if the trouble is that it simply won’t start up. That seems counterintuitive, but it’s true: the heat pump can be in perfect working order but still not turn on.

The good news, then, is that your heat pump is fine and you won’t have to pay an arm and a leg to fix or replace it. Still though, these types of problems can very frustrating to diagnose and correct. Here are four common culprits when a heat pump won’t start:

  1. No power to the heat pump. Check your breaker box to see if the circuit breaker was tripped. If so, reset it and see if that fixes the problem. Another possibility is that your heat pump is wired to a wall switch, or that there is a switch on the unit itself. Make sure the switch is turned on.
  2. Make sure the thermostat is set to the proper mode, such as “heat” mode if you desire more heat. It seems overly simple, but sometimes the trouble is as simple as that.
  3. A recently replaced thermostat. If you recently upgraded or replaced the thermostat in your home, it’s possible that something went wrong that is preventing your heat pump from starting. It may be the wrong kind of thermostat – heat pumps require a specific type – or it may have been improperly wired.
  4. Finally, the heat pump may have its own circuit breaker on the air handler cabinet. This is often the case with heat pumps that have supplemental electric elements. If that breaker is tripped, that could cause the problems you are experiencing.

If you exhaust these problems and the problem persists or recurs – for example, if the circuit breaker trips again – call RineAir Heating & Air Conditioning to work on your heat pump. There may be something larger at work that is causing problems in the electrical system that controls your Fort Thomas home’s heat pump, and that requires some expertise to properly address.
