Benefits of Geothermal HVAC Systems

If you’re looking for an HVAC system that makes use of the earth’s energy for cooling or heating your space then investing in a geothermal system is a great idea. These HVAC machines operate by cooling and heating your house using the fairly constant temperature under the surface of the earth. When properly equipped, these systems can also supply the house with hot water for free.

Do not confuse geothermal HVAC systems with geothermal power plants. The latter generates electricity by using the earth’s core. However, a geothermal heating system uses the earth’s crust to cool and heat a home; there is no electricity generation involved.

How do they work?

Operation during winters: The pipes underground, also known as the ground loop, circulate water which in turn absorbs the natural heat of the earth and brings it to the heat pump installed indoors. This heat pump excerpts the heat from the water and distributes it within the house as warm air. Once the water’s heat is removed, the same water is re-circulated for collecting more heat.

Operation during summers: Indoor heat pumps suck the hot air from the house to get rid of the heat. This in turn leaves cool air behind to be dispersed through the vents. The heat that is removed from the house is released into the earth with the help of the ground loop. The ecologists acknowledge and regard geothermal systems as the most environmentally clean, energy efficient, and cost-effective systems available in the market.

Here are a few benefits that make these systems so lucrative to homeowners.

More energy efficient:

According to experts, almost 70 percent of the energy used by geothermal HVAC systems comes from renewable energy sources within the earth. A geothermal HVAC system which is energy-efficient is approximately seventy five percent more competent in comparison to an oil furnace, 40 percent more competent when compared to a gas furnace and 43 percent more efficient when it is operated in the cooling mode.

More economical:

While the installation cost of geothermal systems is at the higher side, the HVAC system will gradually pay for itself as it will reduce the monthly utility bills and decrease your annual cost or maintenance. In comparison to a conventional system, you will get a much higher investment return when you buy a geothermal system.

Environmentally sustainable:

Geothermal cooling and heating systems are known to be one of the safest option available in the market when you keep environmental friendliness in mind. In fact, if you install a geothermal HVAC system in your residence, you basically plant seven hundred and fifty trees or reduce pollution amounting to two running vehicles.

Moreover, a geothermal residential HVAC system does not require fossil fuels to function, which is great for the environment as it eliminates threats resulting from combustion. If you invest in a geothermal system, there is absolutely no need to worry about carbon monoxide or the dangers it poses to the safety of your family.

Why should you get an HVAC Maintenance plan?

There are plenty of benefits for your home, if you decide to get an HVAC maintenance plan. Before looking at the advantages, let us first understand what these maintenance plans are all about.

HVAC service contracts are agreements between the HVAC owner and a service provider where the owner has to pay a certain fee to get the company's continual services for the system. The most basic plans include tune ups and checkups, emphasizing the air conditioning before summer and your heating system before the winter. There are also contracts that include services for issues found at the time of checkups, while some comprise of emergency services. The fee of the plan will depend on the number of services included in the contract.

Why sign up?

Here are some of the most lucrative advantages to signing up with a reputed HVAC maintenance provider.

Get protection for your warranty:

Manufacturers of your HVAC will not honor the warranties when the machine is neglected. Most expect owners to get the system maintained twice a year - normally in the fall and spring - and this is exactly what the HVAC system maintenance plan offers. Trained and experienced technicians will visit the house and make sure the system is running smoothly. You will secure your warranty, and the technician will take care of your system.

Enhance the longevity of the HVAC system:

When hiring professionals for maintenance, your air conditioner, furnace, and other HVAC components can last longer. They lubricate and clean the system’s moving parts and check for leaks in the refrigerant and other problems. You are going to get more mileage from your investment. This will save you a lot of money.

Enjoy priority appointments:

Most HVAC service providers value their maintenance plan members so much that they send them right to the priority list when they schedule service appointments during peak seasons. If you have any emergency related to HVAC, you will get a technician to rectify the issue as soon as possible.

Priority treatments can save you discomfort and time when your heater stops working in the extremely cold weather or your air conditioner starts blowing hot air during the summer months.

Energy efficiency:

High energy bills can be a big problem. A maintenance program makes sure that the system keeps on running at optimal efficiency. You will not just spend a lot less on your energy bills, but also decrease carbon footprint. Lesser the energy consumed, more beneficial it is for the environment.

If you hire a qualified technician for inspecting your HVAC system you can identify problems when they can still be fixed easily, instead of waiting till they harm the HVAC system or become too expensive.

One of the biggest investments you can make for your house is to get a good HVAC maintenance plan from a reputed contractor. This will ensure that your expensive system works in its best capacity at all times. It will also ensure that your system remains clean from debris and dust particles, making sure your children breathe fresh air at all times.

How to Prolong the Life of your HVAC System?

HVAC is always a costly investment, one every house owner should make only a few times in their lifetime. According to experts, a system lasts for approximately fifteen to twenty years, and there are numerous things that homeowners can do to increase the life of their HVAC.

Pre-season check-ups and cleaning

It is very important to get the HVAC checked and cleaned before the start of any season, normally once in the spring and once in fall. This routine helps in catching any issues before the season begins and ensures the system works smoothly. Plan maintenance check-ups and cleaning early to make sure you get hold of efficient and licensed technicians.

Checking air filters on a regular basis

Dirty or clogged air filters can reduce the air flow to your system, creating extra stress and making the HVAC work harder. This may cause damage to the blower motor. When you check the filters on a regular basis, you can avoid the build-up of dust or dirt, eventually causing less tension on the motor and extending the life of your system.

Inspecting the equipment

Inspecting the HVAC equipment regularly can help in catching small issues before they become big. While you will require a technician for inspecting the ducts for air leaks and for maintaining your equipment, there are several things you can do yourself.

Be vigilant about any equipment that is susceptible to excess wear and tear or corrosion. For heat pumps or central air conditioning systems, any parts that are outside the house should be checked visually for buildup of leaves, damage or debris.

Apart from this, every owner must regularly see if there are any leaks in the outside equipment. For instance, finding oily substance on surfaces can indicate towards a refrigerant leak.

Give a break to your system

For most homes, an HVAC system runs seven days a week. This can take a toll on the system. It is very important to give a break to your system to keep it from being overworked. Using an automated thermostat can help, because it will help you adjust the system’s temperature during the day and at times when you are not home. This way, when you get back, it will be less work for your system to get the house back to the correct temperature. Normally, a slight ‘break’ for the HVAC system will make a huge difference when it comes to the pressure on it in the long run, and will assist you in getting maximum savings possible.

There is no way to guarantee or predict the life of an HVAC system. However, with these handy tips you can keep your HVAC running efficiently and smoothly, increasing its life and helping you get the best out of the investment. Also, any time you feel that your system is not functioning properly, make sure you contact a HVAC maintenance expert immediately. The professional will be able to find and rectify the fault before it becomes a costly damage.

Pros and Cons of Underfloor Heating

We all try to reduce our utility bills while keeping our house warm. Underfloor heating is becoming one of the most popular hot air systems in terms of alternatives to traditional fireplaces and radiators. However, how do these systems really work and what are the possible advantages and disadvantages to installing one?

Underfloor heating is the type of central heating system that attains indoor climate control using radiation, conduction, and convection. The words radiant cooling and heating are commonly used for describing this approach as radiation is responsible for a big part of the consequent thermal comfort. However, this use is technically correct only when radiation constitutes more than 50% of the heat exchange between the space and the floor.

Basics of underfloor heating:

There are essentially two kinds of underfloor heating systems –dry and wet. Wet system pump hot water through pipes under the floor for creating heat while dry systems make use of electric coils below the floor to attain the warmth.

Electrical underfloor systems make use of a series of wires for heating up the floor. Wires lay on top of the insulation and work with many different flooring types. However, they do not work under carpets. Installation of electric systems is cheaper when compared to water systems.

The advantages:

One of the things that most people like about underfloor systems is that they are not visible. Unlike ugly radiators they do not take up any space or affect where furniture can be placed as they are hidden under the flooring itself. Since they spread under the entire room there are no cold and warm spots far or close to the radiator.

Underfloor heating systems also do well at low temperatures which decreases the amount of electricity required to operate them. The heating systems work in a more optimal manner than radiators.

The Problems:

There are essentially two main issues with underfloor heating systems. First is, they are very expensive to install, depending on the kind of property you are planning to install them in and the way they have been constructed. They are extremely popular among newly built properties as the designing can be fused in the house but may not work for some older property. Certain flooring types may also not work well with underfloor heating.

The other issue is that they need more time to heat a space than a radiator, so a regulator to help you in organizing the system is essential.

Whether water or electric based, underfloor heating systems are certainly a popular way to heat your home. Several newly built properties incorporate this system and houses undergoing renovation can also consider the same. Some older properties can also consider getting the system installed, bringing a lot of savings to the house owners and decreasing the carbon footprint coming with it. The radiant heat that is produced by the system decreases air circulation and humidity, which means there is a lesser chance of allergens and dust mites in the air.

Heat Pump Systems: A Guide for Home Owners

There are so many different ways to heat a house. From fireplaces to furnaces, homeowners have a range of different choices. But, which is the best one for your house? You have probably heard of a heating pump, but could you tell it apart from a boiler or a furnace?

In this blog, you will learn about heat pump systems, how they work, the kind of systems available, and the best system that will work in your house.

Air-source heating systems

This heat pump system absorbs warmth from the outside air, transferring it in the house. When the heat is moved indoors, the system causes the inside areas to feel a little warmer.

To cool the house, the heating pump draws the heat from the house, sending it to the outdoors. By getting rid of the heat, your house feels colder.

Geothermal heat pumps

Geothermal heat pumps utilize underground heating as an energy source. These systems make use of a ground loop for tapping into the natural ground heat and moving it up to the heat pump of the house, where it is moved indoors for warming up the area.

Such pumps can also pull heat from a close by water source having consistent temperatures, such as a pond or a lake. The heat is transferred into the house.

Are heat pumps right for your house?

Not every house is right for a heat pump system. In some conditions, the system may not provide the required efficiency, and some other kind of heating system may be more realistic.

Climate:

Air-source heating systems only run effectively when the outside weather conditions are above freezing. It is not a good idea to choose a heat pump when temperatures drop below thirty two degrees.

In areas where the temperatures start to reach freezing points, air-source makes excellent primary heating systems. However, you must install a backup system like a gas furnace, which can be used at times when temperatures reach freezing. A HVAC expert can install controls that shut down the heating pump automatically if temperatures drop or reach below freezing point.

Ductwork

If you plan on switching to geothermal pump from a conservative forced air cooling and heating system, you can reuse the existing ductwork of your house. In case you do not have any ductwork installed inside the house, the additional expense of getting ductwork installed may make conventional heat pump systems an expensive choice.

A mini-split ductless heat pump system pumps heat inside the house without any ductwork. Separate indoor units fixed on ceilings or walls connect to the outdoor condenser. House owners benefit hugely from the savings geothermal pumps offer and their characteristic zoned comfort control.

With the right knowledge about heat pump system, you are better equipped for making the right buying decision for a new cooling and heating system for your house. Also, make sure you hire a trustworthy contractor to perform the installation for you, for best results.
