You can save money on a roof replacement by looking for ways to do the work yourself.
It is important to know that there are different types of roofs, and you can’t always tell what type your roof is just by looking at it. So, before you start work on your own, be sure to get a professional opinion about what type of roof you have, or you may end up paying for repairs later.
You can save money on a roof replacement by shopping around for the best deal. This often works best if you are getting an entire new roof installed. You should get at least three quotes from qualified companies to make sure that they are all competitively priced before making your decision.
A roof replacement is one of the most expensive and time-consuming home improvement projects.
- Research, Research and Research: It’s important to research different companies and contractors before making a decision. Check reviews, customer testimonials, contractor ratings, and past work before picking a company for your roof replacement project.
- Get Multiple Estimates: With so many options available today it’s important to get an estimate from more than one contractor to make sure you are getting the best deal possible on your new roof replacement project.
- Compare Materials: Not all roofs are created equal! It’s important to compare the different materials that contractors use when completing a roofing project to find out which option will be best for you and your family.
- Consider Warranties
Explanation of Costs vs. Benefits of Roof Replacement
Roof replacement costs are spread out over the course of 20-25 years. This is when they are used to calculate the total cost of owning a roof. However, when they are only used for the initial installation, they don’t have any major long-term benefits to show for it.
This is because roofs have an expected lifespan of 30 years or even more if you take care of them well. And so, in comparison with regular roof installation costs, it doesn’t seem worth the price tag to replace your roof just yet.
What should you look for in an air conditioning system besides its cooling capacity? The answer is energy efficiency, because air conditioners are now an indispensible part of our daily life and making it energy efficient will cut down running costs that is desired by all. That energy efficiency has always been a concern for people is reflected in the fact that the air conditioners that we use today are much more energy efficient than what is used to be about fifty years ago. Some of the best air conditioners now use at least 30 to 50 percent less energy for producing the same amount of cooling that it used to generate in the mid-seventies. But still, we are craving for further betterment and it makes enough sense not only financially but also from the environmental perspective. Less energy consumption translates into less stress on natural resources which is the need of the hour.
There has been an upswing in the sales figures of air conditioners across the world and the trend continues. This is happening not only because new users are being added every day but because of another interesting fact. Incidences of replacing not so old air conditioners have boosted sales. More and more people are willing to spend on replacing air conditioners not even 10 years old so that they can avail the benefit of enhanced energy saving between 20 to 40 percent by installing new models. This means running costs are being slashed drastically and the technological progress has benefited people even financially.
This is an often heard term that you will come across when you are shopping for air conditioners. What does it really mean? It means a lot in terms of the energy efficiency of the system. Seasonal Energy Efficiency Rating or SEER is an indication of the amount of cooling that the system can achieve by consuming a single unit of energy. The more is the cooling the better is the performance of the system as you get more cooling with less energy. While higher SEER numbers ensure better cost effectiveness, the minimum that is acceptable is SEER 13 for standalone units and SEER 16 for centralised systems.
The popularity of split systems is undeniable whether you choose individual unit or centralised unit at home. The evaporator is housed in the indoor unit of the split system while the condenser and the compressor are located within the outdoor unit. The individual split units are duct less with copper pipe replacing the ducts. These units are easy to install and the sleek and attractive looks of the indoor unit enhances the aesthetic value of the interior decor.
How efficiently an air conditioner can operate depends not only on its manufacturing quality but also on its proper selection. Efficiency is directly related to the right selection of the size of air conditioner. A large unit that operates on multiple on off cycles can turn out to be less efficient than a small unit that runs for extended period. Large units are detrimental for uniform cooling.
The space that has to be cooled, its area and thus the volume determine the kind of cooling load that will be necessary. This is expressed in Tons and indicates the rate at which heat has to be removed from the space to achieve the desired cooling. Besides the area and volume of the space, any additional source of heat that exists in that space has also to be considered. But this is the job of a technical person and the seller of air conditioners can tell you which capacity will be right for you. There is another thing that you have to decide – which type of air conditioner you would like to install. There are three options that you can choose from depending on the area that has to be cooled.
Window air conditioner
This is the simplest and most traditional type of air conditioner that we are all familiar with. It is installed on window sills or similar wall opening hence the name. This is a compact box type unit that houses the entire system comprising of condenser, compressor, coil or expansion valve, cooling coil and evaporator. This type of air conditioner used to be most widely used till the advent of the split system that has also been discussed in this article. The air conditioner is installed in a way so that one of its broad side faces the room while the opposite side is exposed to the atmosphere. The side facing the room is the cooling side while the other side is responsible for removing hot air from the room and release it to the environment.
Split air conditioner
As the name suggests this variant of air conditioner has two units that are connected by copper tubing – the outdoor unit and the indoor unit. The condenser, compressor and expansion valve is housed in the outdoor unit while the cooling coil cooling fan and evaporator is placed inside the indoor unit. The indoor unit is generally mounted on the wall but if need be, it can also be floor mounted or ceiling mounted. Split air conditioners are now looked upon as indoor decorative items as it enhances the aesthetic value of indoors, are more compact and sleek in appearance and requires minimum space as compared to window air conditioners.
Packaged air conditioner
If you want to move away from the concept of individual cooling of rooms, then you have to look for packaged unit of air conditioning Adelaide. This is the choice for very big size of homes, offices and commercial establishments that prefer a centralised system for cooling. These units are available in two types. The compressor, condenser, evaporator and cooling coil are all assembled in a composite enclosure where the cool air is generated and then using blower the cool air is directed through ducts that lead to various parts of the home or office. The cool air is discharged from the ducts through vents or grills that are placed at the duct terminals. In another type, the cooling coil and expansion valve is located in the rooms where the cooling happens.
The volume of air that is circulated within an air conditioning system is greatly responsible for the comfort of users. No matter how cool the temperature is generated from the system, how comfortable one feels will depend on how well the cool air circulates through the room. It is similar to what we expect from a fan running above our head. But there will be occasions when the air flow gets reduced and increases the discomfort of the people inside the room. This is a sign that the system is getting throttled and needs immediate attention.
Before we delve in to the possible causes of the problem, there can be many reasons for it, let us understand the basic working of an air conditioning system. The air conditioner comprises of a condenser and blower. The refrigerant gets compressed in the condenser that produces the cooling effect. The blower discharges the cool air inside the enclosed space where the air conditioner is installed and at the same time displaces the hot air to produce the necessary cooling. The capacity of the blower is suitable for circulating a measured volume of air. When the air distribution system comprising the ducts gets choked, the flow of air reduces and gives rise to discomfort as a result of less cooling. Why does the air flow get reduced?
Fan motor is damaged
The blower or fan that throws air inside the room is driven by an electric motor that can get damaged due to wear and tear or for any other reason. When this happens, the blower simply stops working. Getting the fan motor repaired can resolve the problem. Even if the fan motor is working, check its speed because if for some reason it rotates at a lower speed the draft of cool air entering the room will diminish.
Clean air filter regularly
Air that is circulated in an air conditioning system is filtered prior to delivery into the system to rid it from particles that can contaminate the quality of indoor air. This air filter gets choked by the particles that get trapped inside it and results in blocking the flow of air. The blower is prevented from drawing the right amount of air as the filter is choked. Although discomfort is felt by users there is another unseen harm that is caused by reduced air flow. The system gets over worked in trying to keep the room cool and this reduces its efficiency besides causing wear and tear that can result in breakdown of the system. Inability of the filter to remove allergens from the air can raise health issues.
Loss of cool air from the ducts is another reason why the system may be burdened and people may be derived from the comfort of air conditioning. Ducts are prone to leakage and the system might lose up to 30 percent air if the problem is not detected on time. Regular checking of ducts to seal leaks is an effective way of ensuring comfort for air conditioning system users.
If you live at a place that has ample winter and summer months with temperatures hovering much beyond the ambient then you should think about installing a heating, ventilation and air conditioning or HVAC system. Considering the energy efficiency that you want to achieve, you can select a suitable HVAC system that will help to maintain comfortable ambient temperature inside the home throughout the year. Besides providing comfort, this system will also ensure that purified air circulation that is free from mould spores and allergens and ensures healthy living.
While you are assured of a defined level of pure air, there is scope of improving the air quality further. The system is designed to achieve a desired level of air quality for which suitable filters are used. If you want to get it purified further, you can always do it by installing better quality filters like HEPA filter that eliminates minutest particles from the air. But what kind of HVAC system you choose depends upon your budget, your needs and the kind of technology that you prefer. Systems that are capable of cooling and heating in multiple stages and systems with variable fan speed are all available. Ponder about the following aspects to do the right selection.
First and foremost you have to consider your home layout and the cooling and heating requirements. It is not only about the total load of heating and cooling but when and where it is needed. If you have several rooms across several floors of your home, it is not necessary that the same kind of heating and cooling will be required at the same time across the home. There will be some places where it will be required at times when most other places can do without it. You can select a system that has zoning facility – cooling or heating specific areas selectively. This cuts down on energy bills considerably as the system operates partially without compromising its efficiency.
Single stage and multi-stage system
For those living in areas that have extreme temperatures in summer and winter installing a HVAC system that is capable of providing comfort on the warmest or coldest day is an ideal choice. A single-stage HVAC can work very well to meet their requirements of comfort. If you want to control the air flow then there is an option of choosing a fan that has variable speeds. But the flip side of the system is that the system will always have to be run at full capacity, hence operating costs will be high. But going for a multi-stage system can solve this problem as it reduces energy consumption thereby lowering power bills.
50 percent is the ideal humidity to provide comfort to humans but the humidity level inside the home depends on the humidity of the outside air that is circulated in the system. Depending on the climatic humidity, use of humidifier or de-humidifier can add more comfort in using HVAC systems.
Knowing your requirements would precede the selection of HVAC system that is right for you.
