Services
Heating & Air
It is a fact that you may come across unreliable HVAC contractors at one point in your life.
You may find people who share their horror stories about how their HVAC systems were not properly installed, or how substandard electrical work had started fires in their homes.
If you have a need for an HVAC contractor in Martinsburg, WV, or anywhere for that matter, there are a few important things that you need to look for in the company you plan to hire.
Before hiring a contractor, you need to be certain they have the license to provide services in the state.
Heating Department
The heating system is one of the most important elements of your home.
Although you probably rarely think about it when it works, a fully functioning heater is necessary for a warm, comfortable, and safe home.
In addition, installing the right system for your house is crucial for saving money on energy bills.
At R.C.S, we have a highly trained team of experienced professionals who can install or repair a wide range of heating units which includes heat pumps, oil or propane furnaces and boilers, and electric central heating.
Air Conditioning
Selecting an air conditioner for your home is a big decision, it's an important investment today.
It will also play a key role in your home energy expenses for years to come.
When the summer heat is at its worst, you'll want your family to have the best, most reliable cooling comfort possible.
Obviously, an air conditioner that's too small won't keep your home sufficiently cool.
But what many don't realize is that an oversized system will cycle (turn on and off) more than necessary, wasting expensive energy and possibly putting undue strain on the compressor.
Electrical
When you require electrical repair or installation in your home, you will likely need the service as soon as possible.
Sometimes, homeowners who enjoy DIY projects will attempt to do this kind of work themselves.
This can be a grave mistake.
Only a skilled electrician should perform such services at your place of residence.
Be sure that you choose a reputable, licensed professional to do the job.
A residential property might require a wide range of electrical repairs.
If you are experiencing electrical issues in your home, you should contact an expert immediately.
Duct Installation
We all know what ducts are.
In every structure where the ambient air is either heated or cooled, you will find a sprawling network of ducts.
Often a popular setting for scenes in action movies, ducts are those shiny sheet metal crawlspaces that facilitate the movement of both good and bad guys through the insides of a building.
While ducts do not always make a convenient form of travel for people, they excel at facilitating a healthy flow of air throughout your commercial or residential structure.
Air Cleaners
Air pollution within the home is not something one worries frequently about, but the EPA has named indoor air pollution as one of the top five environmental risks to public health.
Many believe that outdoor air has the pollution that is hurtful, but the EPA reports that indoor air is over one hundred times more polluted than outdoor air.
By utilizing an air cleaning system in your house, you can make your home the safest place to breath.
Trenary Service Company in Martinsburg, WV can install an air cleaning system for you today!
Thermostats
The thermostat, or thermostats, in your home are probably the most recognizable component of your home's heating and/or cooling unit.
It acts as the control unit for your HVAC unit and allows you to set the overall temperature of your home.
What you may not know is that an improperly installed or poorly working thermostat can affect the comfort level inside your home and increase your home's monthly energy costs.
If your heating and cooling system does not seem to be working properly, your thermostat may be the culprit.
Tankless Water Heaters
Tankless Water Heaters are innovative, energy efficient water heating solutions for today's homes.
From point of use applications to whole home systems.
Imagine never running out of hot water again.
Homes with busy families.
Enough hot water to load the laundry, start the dishes, bathe the kids and still have enough to enjoy a relaxing shower of your own.
Homes with luxury bathrooms.
Master bathrooms are meant to be luxurious and Tankless water heaters can support the hot water needed to bring them to life.
Indoor Air Quality
When most people think about air pollution, they probably picture billowing clouds of smoke and toxins spewing from industrial smokestacks or city skylines turned brown by car exhaust fumes.
However, according to the U.S. Environmental Protection Agency, your indoor air could be as much as 100 times more polluted than the air outside.
It has ranked indoor air pollution among the top five environmental hazards we face.
Because we spend nearly 90 percent of our time indoors, indoor air quality should be a major concern.
Humidifier
Many associate winter with dry skin, scratchy throats, and asthmatic coughing.
However, did you know that there are ways to enhance your home to prevent these symptoms?
A whole-home humidifier fills your home with moisture, and takes away many of the symptoms that people blame on the cold weather.
Overly dry air can cause much more than just dry skin.
Viruses grow much easier in a dry environment, which means your family is at risk of getting sick.
Infection also is more likely to occur in dry environments, according to the American Society of Otolaryngology.
Dehumidifier
A dehumidifier is used to get rid of excess humidity and moisture in your home, which causes mildew and mold to form.
Many homeowners today use dehumidifiers for a number of reasons.
If you are looking into buying a dehumidifier for your home, looking into these reasons can help you decide whether to continue with this purchase.
Apart from eliminating excess moisture and humidity, humidifiers also help to get rid of pests and bugs that are common if you live in areas where there is a high level of humidity most of the year.
HVAC for Custom Homes
If you are building a new home, you know there are about a million things to keep you busy in the construction process and about ten million reasons to be awake at night worrying.
Sometimes the things you cannot see, like HVAC setup, may become lost in the shuffle that can be a burden in the future, considering your home builds around the layout.
HVAC plays a major part in how comfortable you and your family will be year-round.
If your HVAC system is not well designed or installed, comfort issues will be a problem you will face, an issue most people would like to completely bypass.
