Signs That You Need a New Air Conditioner

April 27th, 2015

Summer is coming, and that means it’s time for us to get our air conditioners ready for the hot season. For some of us, however, it will mean replacing our air conditioners. No matter how well you take care of your air conditioning system, there will come a time when you have to replace it. The last thing you want is to have your air conditioner die on you in the middle of a hot summer day. That’s why it’s a good idea to replace it now, before that has a chance to occur. The following are some of the most common signs that you need a new air conditioner. Continue Reading

Why You Need to Worry about Your Indoor Air Quality

April 20th, 2015

You may not spend much time worrying about your indoor air quality. After all, you seem to be breathing fine; as long as there isn’t an obviously dangerous substance in the air, what is there to worry about? Well, the air in the average home is actually full of millions upon millions of microscopic contaminants. Things like dust, pollen, insect dander, and pet dander can all provoke allergy attacks. Meanwhile, viruses and bacteria can make you sick with a cold or flu. Read on to find out more about how these contaminants can affect you, and how you can protect yourself. Continue Reading

Ways That Zone Control Can Improve Your Air Conditioning System

April 13th, 2015

With summer fast approaching, it’s time to start thinking about how you’re going to keep cool during the coming hot days. While a centralized air conditioning system is the option that most homeowners choose to cool their homes, it has its share of problems. One room may cool down quite quickly, while another in the same house may require more time to reach a comfortable temperature. A central air conditioning system is often controlled by a single thermostat, which makes it unable to compensate for the variations in insulation present in each room. This leads to hot and cold spots, as each room is subject to a one-size-fits-all cooling solution. Central air also tends to waste a lot of energy cooling rooms that don’t have anyone in them to benefit.

Does My Heat Pump Need Maintenance in Spring as Well as Fall?

April 6th, 2015

An important piece of advice you will hear from heating and cooling contractors is that you must schedule routine maintenance for your home’s comfort system twice a year: spring for the air conditioner, and fall for the heater. This way, you’re prepared for the coming temperature extremes of the upcoming season.

But what if you have a heat pump, which is a single system that handles both heating and cooling? Do you only need to schedule maintenance for it once a year?

The answer is no. You need to treat your home’s heat pump as if it were two separate units—a heater and an air conditioner—for the purposes of maintenance. So, before the summer arrives, take time this spring to call on your local HVAC experts and arrange for spring maintenance service. Then keep up with the twice-a-year schedule for the rest of the service life of the heat pump.

Call on RineAir Heating & Air Conditioning today and ask about our Maintenance Program to care for your heating and cooling in Anderson, OH.

Although a heat pump isn’t two separate systems packaged into one, but a single mechanism that can switch the direction it works, it still must have maintenance done with the same frequency as if it were two different systems. The reason for this is simple: stress. A heat pump does not get a break for a season the way that a standalone air conditioner or heater does. A furnace will perform steady work from late fall until early spring—and then may not turn on again for months. The same applies to an air conditioner and its long winter vacation.

But a heat pump will need to work during most days of the year, with the exception of some of the milder days of spring and fall. This adds up to an enormous amount of wear and tear on the compressor, the motors, the fans, the electrical system, etc. Maintenance is necessary at the beginning of both the heating and cooling season to alleviate the stress of the previous part of the year.

So, before your heat pump settles into cooling mode for the coming summer, call up RineAir Heating & Air Conditioning and have one of our maintenance technicians give the system an inspection and tune-up. Our Energy Savings Agreement will provide you with maintenance as well as other benefits such as a 15% discount on repairs and no overtime charges.

Why Low Refrigerant in an AC Is a Major Problem

April 3rd, 2015

One of the key parts of an air conditioner is the refrigerant. This is a chemical blend that can easily shift between liquid and gaseous states. The refrigerant is responsible for moving heat from the inside of a home and releasing it to the outside. Each air conditioner comes with a set level of refrigerant, known as its charge; if the air conditioner should lose refrigerant charge, it will impair the system and lead to inferior performance and possibly a complete break down.

If you suspect that your air conditioner is losing its cooling ability because of a loss of refrigerant charge, call for repair help right away. For speedy, 24/7 air conditioning repair in Cincinnati, OH, RineAir Heating & Air Conditioning is the company to call.

There are a number of different operating issues that low refrigerant will cause in an air conditioner. But there are two major ones, both of which can result in an AC that will stop working entirely:

  • Frozen evaporator coils: As cold refrigerant moves through the evaporator coils in the inside cabinet of the AC, it absorbs heat from the air, cooling the air and warming up the refrigerant. But if the refrigerant level is low, it will not draw sufficient heat to warm it up, and the still cold refrigerant will freeze moisture along the coils. This will further inhibit heat absorption, causing more ice to build up. Eventually, the coil will be entirely covered with ice and will not be able to function.
  • Broken compressor: A low refrigerant charge changes the pressure inside the compressor. It can also cause the compressor to overheat. Because the compressor is the “heart” and an AC, the location where energy is passed into the refrigerant and the pump that keeps the heat exchange cycle going, if it breaks the whole system will cease working. A burnt-out compressor is a very expensive malfunction to fix, so make sure you get ahead of the problem when the AC suffers from a low charge.

The refrigerant charge for an air conditioner isn’t like a battery in an appliance or gas in a car: the AC does not deplete the refrigerant as it runs, nor can it continue to do the same job with a lesser amount or refrigerant. The air conditioner is designed to run off a specific charge, and if it changes, it can be catastrophic for the system. You must have professionals find out why the loss of charge occurred (poor initial installation? leaks in the refrigerant lines?) and recharge the unit to restore it.

Get in touch with the experienced HVAC technicians at RineAir Heating & Air Conditioning for our quality air conditioning repair in Cincinnati: whether you have low refrigerant or another problem, we will fix it for you, fast and right.

AFUE and HSPF: Heating Efficiency Ratings

March 25th, 2015

How energy efficient is the heater that warms your home? There’s an easy way to determine how energy efficient it should be: look at the efficiency rating listed on the cabinet. If you use a furnace, the efficiency rating is listed as AFUE. If you use a heat pump, it has two efficiency ratings: SEER and HSPF, one for cooling mode and one for heating mode respectively. Understanding what these ratings mean will help you understand how your heating system works, as well as help you pick out a new unit when it’s time for a replacement installation.

No matter if you use a heat pump or a furnace in Anderson, OH, the team at RineAir Heating & Air Conditioning can help you receive the best quality performance from it with our repair and maintenance services. We are also expert installers and will see that you have a heating system with the ideal energy efficiency for your home and budget.

AFUE: Annual Fuel Utilization Efficiency

The energy efficiency rating of a furnace is AFUE, which is the percentage of heating fuel that the furnace converts into actual heat as measured over a year. If, for every 100 units of natural gas, a gas furnace generates 85 units of heat, it has an AFUE of 85%. Most modern furnaces fall in a range between 80% and 97% AFUE, with high-efficiency condensing furnaces scoring the best ratings. Higher AFUE usually translates into a costlier unit, but it will also mean significant energy savings over time. Let your furnace installer help you determine the AFUE rating that will work best for your current and future needs.

HSPF: Heating Seasonal Performance Factor

Because heat pumps do not burn fuel to generate heat the way that furnaces do, instead using electricity to move heat from one place to another, they have a different type of efficiency rating. HSPF is a ratio of the amount of heat a unit produces to the amount of electrical energy it uses as measured over a season; the higher the number, the more efficient it is. A standard HSPF rating for a heat pump is around 9 or 10. HSPF is similar to SEER, which measures a heat pump’s cooling efficiency, but is usually lower. When purchasing a new heat pump, you will need to take both ratings into consideration.

Keep in mind that energy efficiency isn’t the same as energy output. A system may work at high efficiency but still not produce enough heat to keep a home warm. When you are in the market for a new heating system, make sure that you have heating professional, such as those at RineAir Heating & Air Conditioning, assist you with determining the right balance of efficiency and heating power to meet your needs. We are here to help you with new installation, repairs, and maintenance for furnaces or heat pumps in Anderson, OH.

Open Loop vs. Closed Loop Geothermal Systems

March 20th, 2015

Are you considering investing in a geothermal heat pump for your home comfort? You are not alone: more and more households every year are converting from using standard air-source heat pumps to ground-source geothermal heat pumps. The benefits are excellent: efficient heating even during the coldest winter temperatures, energy-saving performance, long system lifespan, and a reduction in emissions that can harm the environment.

When you are considering a geothermal installation for your home, you must also make a number of important decisions about the type of geothermal system you want. One important choice is between an open loop and a closed loop system. RineAir Heating & Air Conditioning will help you make the right decision for your home, and you can trust our Cincinnati, OH geothermal specialists to give you the best installation possible.

What’s the difference between closed loop and open loop systems?

  • Closed loop: The geothermal system consists of buried piping that circulates a mix of water and anti-freeze. This solution absorbs or deposits heat from the ground, and then enters a heat exchanger in the home that transfers heat with the refrigerant in the heat pump. The loops are either laid in a horizontal configuration (if there is sufficient space) or placed as vertical loops through drilling.
  • Open loop: The piping doesn’t carry refrigerant, but instead uses nearby groundwater for the heat exchange process. The water does not circulate but is sent into drainage after it is used.

Of the two, closed loops systems are the more common. An open loop system must have access to a significant source of ground water, and are therefore not suitable for all homes. Open loops can also pick up debris inside their piping that can lead to repair issues. Ask a geothermal installer about some of the specific differences between the two that relate to your home; in some situations the less common open loop system is the better option.

We encourage many customers to investigate the possibilities of going geothermal in Cincinnati, OH. You might think it’s impossible for your home to benefit from a geothermal heat pump, but you may be pleasantly surprised. Give RineAir Heating & Air Conditioning a call and ask to speak to our geothermal specialists. They will help you make the best choice when it comes to setting up your home to use the power of the earth for year-round comfort.

Why Is My Boiler Rumbling?

March 11th, 2015

Unusual sounds coming from a heating system are often a warning sign that the heater needs to have professional repairs. You will have a good idea of what kinds of noises the system makes during regular operation, and when it deviates from this pattern, don’t hesitate to call on technicians to take care of it. If you let those strange sounds continue, it can mean larger repairs later on, elevated energy bills, and even an unsafe heater.

The experts at RineAir Heating & Air Conditioning provide heating repair for Anderson, OH and the surrounding areas. One type of warning noise that we’d like to point out is rumbling coming from a boiler. This sound can often cause people to feel panicky that their boiler is about to burst; if that gets them to call for repairs right away, it’s positive—although it is extremely rare for a boiler to actually burst. But rumbling sound often indicates a number of different problems that need attention.

Frequently, the cause of the rumbling noise is a malfunction in the mixing valve in the tank. This will cause hot and cold water within the tank to mix, which is what creates the rumbling sound. The valve will need to be repaired to prevent the boiler from performing inefficiently.

Another cause is a rise in pressure inside the tank. There are different causes for this. Excess sediment building up along the bottom of the tank over time will decrease the volume of water in the tank and cause the pressure to rise. The expansion valve, a device above the tank designed to provide a cushion for air pressure without allowing air into the tank itself, can malfunction and cause the pressure to spike. Or it could be a problem with excessive limescale along the interior of the tank, which acts as an insulator that will cause the water to overheat and increase pressure. A professional heating technician will analyze the boiler and determine what is causing the problem, then provide the repair work necessary (tank flushing, repairing the expansion tank, descaling the tank interior).

You can trust that the experienced technicians at RineAir Heating & Air Conditioning can provide the heating repair in Anderson, OH you need. Never try to troubleshoot the problem on your own: give us a call, any time of the day or night, and we will take care of the problems with your boiler.

Are Geothermal Systems Better at Heating or Cooling?

March 4th, 2015

Among the many options you have for heating and cooling your home, one of the most efficient and environmentally beneficial is the geothermal heat pump (also known as a ground-source heat pump). Although geothermal systems are major installations, and they will not work for all properties, they provide immense benefits in terms of cost-effective heating and cooling and are more dependable than standard air-source heat pumps.

If you are interested in installation in Cincinnati, OH of a geothermal system for your home, call the specialists at RineAir Heating & Air Conditioning today to schedule an appointment.

Heating vs. cooling with a geothermal system

Because people tend to link the concept of “heat” with geothermal energy (the earth grows warmer the deeper down you go), they often imagine that a geothermal system is only good for heating a home. Even if they understand that geothermal systems are heat pump that can also provide cooling, it still seems sensible that they would work better in heating mode than in cooling mode.

The truth is that a geothermal heat pump operates as effectively as an air conditioning system as it does a heating system. A ground-source heat pump uses the stable temperature of the earth as a heat sink to deposit the heat absorbed from the indoors. The temperature in the earth about 6–10 feet below the frost line (the standard depth at which the geothermal refrigerant loops are laid) remains stable at around 55 degrees. This is cool enough to make it easy to release heat from indoors, and also warm enough to make it easy for the heat pump to operate the reverse direction and draw warmth into a home.

It is true that geothermal heat pumps have an advantage as heating systems over standard air-source heat pumps. If the outdoor temperature drops below freezing, an air-source heat pump will start to lose efficiency. A geothermal heat pump won’t suffer the same issue, because it always has the stable underground temperature. So a geothermal heat pump isn’t better at heating than cooling, but it is certainly better at heating than a standard heat pump.

We definitely suggest that you look into geothermal in Cincinnati, OH for your next heating and cooling installation. Our skilled and knowledgeable technicians are glad to talk to you about the possibilities, so give us a call today.

Is a Heat Pump Installation Sufficient for My Needs?

February 25th, 2015

Among your options for heating installation in Anderson, OH is a heat pump. Unlike other popular types of heaters, such as furnaces, heat pumps are capable of serving the dual function of also cooling down a home. If this makes a heat pump sound immediately appealing to you, then please give our technicians at RineAir Heating & Air Conditioning a call. A heat pump may be just the right new installation to provide your home and family with year-round comfort.

However, a heat pump is not always the best choice for an individual home. Although heat pumps are extremely effective when it comes to working as air conditioners, they can sometimes experience trouble when it comes to heating in some situations. The reason for this is that heat pumps work through the process of heat exchange: the system draws ambient heat out of the air through refrigerant coils and then shifts the heat to another set of coils where it releases it. In cooling mode, a heat pump absorbs this heat from the indoor air, providing lower temperatures inside. When a heat pump switches over to heating mode, it draws the heat from the outdoor air and brings it inside.

This immediately brings up the question in people’s minds: “If I run the heat pump in heating mode during the winter, how is it drawing heat from the cold outdoor air?” The answer is that there is always some ambient heat in the air, no matter how cold it gets outside. If there molecular motion exists, then heat exists. Heat pumps do not experience difficulty drawing effective levels of heat from outside when the temperature is still above freezing. As the temperature drops below freezing, a heat pump may begin to perform less efficiently, although it will still provide heat.

Whether a heat pump will work for your specific needs is something you need to take up with heating and cooling professionals. They will perform a heat load calculation for your home to determine the level of heating it needs for comfort, and then figure out if a heat pump can match these requirements.

The heating and cooling technicians at RineAir Heating & Air Conditioning are here to assist you when it’s time for a new heating installation in Anderson, OH. If you are interested in a heat pump for your home, give us a call and we will set up an appointment to find the ideal new unit to serve your needs.
