Heating and Air Conditioning Systems

Heating and air conditioning systems have the dual function of heating your home in winter and keeping it cool in the summer months. They can be fueled by gas, oil and electricity. There are some systems that are powered using solar or wind power but they are quite unusual at the moment.

Although they are great systems, they are not without their problems. Some central heating and air conditioning systems can dry out the air in your home causing problems for those family members who suffer from asthma or allergies. The extent of the problem will depend on the area of the country you live in as humidity plays a huge factor. If it is becoming a problem in your home talk to your heating contractor about installing a humidifier. If you live in SC, have a chat with Hatfield Heating and Air who are experts in this field.

Most homes already have a basic system installed but when you move house you should review the existing package with a specialist heating contractor. It may have suited the requirements of previous residents but that doesn’t mean it will be the best package for you. It is also worth doing this if you have lived in your property for a number of years as systems have been modernized. A new central heating and air conditioning system may be expensive but you could find that the cost savings you achieve in your energy bills together with the higher standard of comfort you enjoy in your home are worth it.

Always have your HVAC system checked regularly. It should be serviced at least once a year to keep it in top condition. Failure to maintain a heating and cooling system will result not only in higher bills but also in you having to replace the entire system sooner rather than later. The HVAC indoor air quality may also be affected. Any cracks in the hoses will be picked up and repaired. Filters should be changed in accordance with instructions which could mean that this should happen once a month.

The Search For Quality Heating and Air Conditioning Contractors

Home owners can find a large amount of heating and air conditioning contractors that provide professional services for those who need to improve their heating and cooling systems. Therefore, the importance of picking one that can save you money and be efficient cannot be overemphasized. Homeowners should start by learning how these systems work. Learning the ins and outs of heating and air conditioning systems will provide you with insight on what factors to look for during your research.

Lack of knowledge about heating and air conditioning systems has resulted in home owners picking the wrong people for the job. Some companies make claims as to providing quality services but their knowledge and expertise is limited to general expertise only. When speaking to the contractor that you are considering to hire, it is important that you have enough knowledge so you can discuss the project with them in an in-depth manner.

Start your search for a heating and air conditioning contractor by compiling a list of as many companies as possible. It is now made easy by the advent of internet search tools. All you have to do is run a quick internet search. After that, create a short list of all of the service providers within your area.

Your next step should be focused on narrowing down that long list of heating and cooling systems companies. Depending on your priorities, you can narrow down the list according to the services provided or the price range. It is up to you to decide which factors to consider when narrowing down your list of options to ensure that you have the right team working for you.

With your updated list, perform an extensive research and background check on each of the heating and air conditioning contractors. Ask them for proof or certification of license. An HVAC contractor must have the proper license for this technical job that requires extensive knowledge and skills. If the contractor has several years of experience, then that would be a bonus. The years they have spent in the industry can be a good indicator of their reputation and the quality of their service in this cutthroat industry.

There are several benefits to hiring the most competent heating and air conditioning contractor for your project. Thus, there is no need to rush into the process. Keep in mind all of the things that were stated above. You can also prepare your own checklist keeping your personal priorities in mind. However, it is very important to be prepared during your search to make your choice easy to make.

5 Tips for Choosing Your Next Heating and Air Conditioning System

Most of us can’t imagine living in a place where the heating and air conditioning is hit or miss. After all, there is much to be said for being able to step inside on a hot summer day and finding respite or walking into a toasty warm room after spending time in blustering wind and cold. Consequently, when it comes to heating and air conditioning systems for your home, you want to be sure that whatever system installed is able to meet your home’s needs.

But there are a number of heating and cooling systems available on the market, and sorting through the various pros and cons of each can be time consuming. Rather spending time making phone calls and studying numerous websites, here are some things to keep in mind when selecting your next heating and air conditioning system:

· Typically, if you live in a climate where the temperature rarely goes above 85 degrees Fahrenheit then having both a heating and air conditioning system is overkill, and you can get by with just a heating system.

· Quite often, the simplest solution to your heating and cooling needs is the best one, not to mention, the least expensive one.

· Conversely, just because you opt for the simplest heating and air conditioning system solution+, it doesn’t mean that you should settle on a lower quality system. That $300 you save now can come back to bite you a few years down the road with a $1,000 repair that could have been avoided if you had spent the little bit extra at the outset. A good quality furnace can last for as much as 20 years – especially if it properly maintained!

· Don’t buy a bigger system than you need. Not only will this cost more at the outset, but it will cost more to operate. In fact, having an oversized system will actually cause excess wear and tear on your heating and air conditioning system’s components. Ask a local HVAC specialist to tell you what size system is best suited for your home. (This determination is made based on the size of your home, the amount of insulation and the local climate.)

· Choose a heating and air conditioning system that allows you to use local HVAC specialist. If your system must be serviced by someone from out of town this means you will be waiting considerably longer when there is a repair needed.

Selecting a heating and air conditioning system does not need to be a stressful process.

About Commercial Heating and Air Conditioning

Commercial heating and air conditioning is commonly referred to as HVAC systems, which stands for Heating, Ventilation and Air Conditioning systems. These systems are used for maintaining comfortable temperatures and air quality in homes and large buildings. The main purpose is to make the environment healthy and safe in terms of temperature and humidity. The laws of heat transfer, fluid mechanics and thermodynamics are used for designing.

HVAC systems are aimed at improving air quality, providing ventilation and maintaining pressure. Room air distribution methods are employed for delivering air. The ambient conditions and fresh air requirements must be specified whenever designing an HVAC system.

Heating

The heating systems used in HVAC can be any of the several kinds available. In cold areas, central heating is implemented. The system consists of a furnace, boiler and heat pump. Air control is maintained from a central location like a furnace or mechanical room.

Water is used as a medium for transferring heat. Pipes and ducts serve as passage for the heated fluid which is transferred to rooms through radiators. Radiators may be wall mounted or fixed under the floor.

The pump circulates water and ensures an equal supply of heat to all locations. If the weather is warm, the same pipes and ducts are used for cooling. The heating process may also be achieved through resistive heating. An electric current is used for heating conductive filaments.

There are a few considerations which should be kept in mind. Heat pumps are efficient but more expensive. They should be used in moderate climates only. Radiators should be situated near windows or in the colder parts of the building. Harmful gases are formed if the heating system is not working correctly. This is why proper ventilation is a must for every commercial heating and air conditioning system.

Ventilation

Ventilation is classified as mechanical or forced and natural. In the former kind, an air handler is used to control the air quality through dilution of inside air or substituting it with fresh air. Mechanical or forced ventilation is not energy efficient in humid regions.

In these areas, exhausts, direct drive fans are used for controlling air quality and humidity as well. In cold areas, ceiling fans can also be utilized to achieve ventilation. They circulate the warm air in the upper portion through the entire room.

Natural ventilation does not use any mechanical equipment. It ventilates a room with open windows, vents or openings in the wall. It works well only in small areas but is still widely used due to economical prices and no energy consumption.

Air Conditioning

Air conditioning systems remove heat from a room using radiation, convection and even heat pumps. The process is termed as the refrigeration cycle. The systems are designed not only to cool the area but also to ventilate it and control air humidity. Sophisticated designs employ a reversing valve which automatically switches between heating and cooling a room depending on the outside climate.

There are central cooling systems but they can be installed only when a building is being constructed. Retrofitting them in an already built structure is difficult because the ducts are very large. In such cases separate coils for indoors and outdoors can be used. The two units are connected through pipes, providing a passage for the refrigerant.

Dehumidification is important in air conditioning systems. Evaporators or open chiller cabinets are used for the purpose. Basements serve as good locations because water density is higher in the air at lower levels and temperatures. Filtering is also necessary for removing particle sand gases, which can be dangerous. The filtering and condenser coils must be cleaned regularly because the dirt built – up can damage the compressor.

What to Look for in a Heating and Air Conditioning Contractor

Most of us couldn’t imagine what life would be like without our heating and air conditioning units. This is especially true during the worst of summer and winter when temperatures can make life practically unbearable if you don’t have the help of an air conditioning or heating unit working to make things comfortable. That’s why, if yours suffers any problems or you simply need to have it inspected, you don’t want to waste any time or money on heating and air conditioning contractors who won’t do the best job possible. Fortunately, there are some easy ways to make this process a simple one.

Ask Around

This is probably the easiest way to get a short list of excellent heating and air conditioning contractors in your area. Whether you need heating or air conditioning installation, repairs or inspections, no advertisement is better than someone you trust reporting that they had a good experience with the professional they used.

Go Online

If you don’t know enough people who have used heating and air conditioning contractors, you’re far from out of luck. Go online and take advantage of the countless review sites out there. Obviously, you don’t know the people leaving the reviews, so take each with a grain of salt.

Ensure They’re Licensed

The necessary credentials will differ by state, but every serviceman who wants to work on your HVAC unit has to be certified and licensed to work. If they’re not, don’t bother considering them, even if you’re offered a discount to ignore this issue. For one thing, it doesn’t say much for their professionalism if they won’t even take the time to get the proper credentials necessary to work legally. However, it may also reflect that they’re out of the loop in terms of best practices in the industry.

On this same note, never let anyone on your property until they’ve proven they’re insured. Otherwise, if they get hurt or break something, you could be the one held responsible.

Confirm They Know Your Make and Model

Finding the right heating or air conditioning service means asking about which makes and models a serviceman has experience with. Just like not all mechanics are experienced with working on certain cars, many repairmen simply may not know the type of HVAC system you rely on. Always go with those who have trained on and/or worked on your specific type of unit.

Always Get Estimates

Always get a quote before allowing anyone to work on your unit or install one for you. Preferably, you want it in writing so there’s no confusion later.

Furthermore, when you want heating or air conditioning installation, a serviceman will generally visit your home to take a look at what the process will entail prior to providing you a quote. However, you should expect the same kind of service when you simply want heating or air conditioning service on a preexisting unit. Until they see your unit, don’t take any quotes seriously.

Don’t put off repairs, inspections or installation a minute longer. Using the above advice, get the contractor you need today.
