HVAC Contractors in Howard County MD Provide Numerous Heating & Air Conditioning Services
Heating, air conditioning, and ventilation contractors in Howard County MD perform specialty tasks that are beyond amateur repairman abilities. When considering HVAC contractors, keep in mind the climate in which you live, and if there are areas within your home or business that are difficult to ventilate. HVAC contractors in Howard County MD rely on this information to take the appropriate measures for installation of air conditioning units, furnaces, heater installation, ducts, home cooling systems and all types of ventilation systems for homes and businesses.
Good HVAC contractors in Howard County MD provide HVAC repair or maintenance for several commercial or residential applications, such as central heating and air systems, general duct cleaning and repair, reconditioned air, radiant heating, geo-exchange systems, and radiant floor heating.
Some HVAC contractors will perform duct cleaning or repair and can even design and build a new energy-efficient air conditioning system or heating and cooling system for your home or business.
Choosing a New HVAC System in Howard County MD
The best HVAC contractors will not quote a system just based on the square footage of the home, but will survey themselves each room to be serviced by a climate control system. Knowing the total volume to be heated or cooled allows them to figure the load, meaning how much power your system would need and will also facdtor in your type of insulation, window space, and local climate data.
Next, the HVAC experts will determine the best location for your system. The amount of work an air conditioning unit will have to do can depend on where it's located, such as whether or not it's somewhere shady.
Air Conditioner Repair in Howard County MD
An HVAC contractor should be used for any air conditioning repair and service other than routine cleaning, as the main components are sealed, and complex.
Central air conditioners usually are connected to a home's forced-air distribution system, if the home has one. The two main components of a central air conditioner are the condenser and the evaporator. The condenser unit is usually outside the home on a cement slab. The evaporator coil is in the duct above the furnace. Hot air is cooled by the evaporator as it flows through the return-air duct to the furnace. If the air conditioner unit outside works but isn't cooling the house, the problem is probably in this distribution system where the evaporator is located.
Central air conditioners should be inspected and adjusted by an HVAC contractor before the beginning of every cooling season.
Forced Air Heating - Forced air heating systems are the most common type of home heating system and tend to be the least expensive. Air is heated in a furnace and then distributed through the building or home via air ducts. Different furnaces use different fuels, such as propane, oil, natural gas, or electricity. A forced air heating system requires air ducts, which take up space in your building or walls, and it requires regular air filter changes.
Radiant Heating System - Radiant heating simply refers to the direct transfer of heat, such as from a stove. Hot water tubing in a floor also comes under this category, in which case the hot water is heated by a boiler. These radiant heating systems tend to be more expensive to install than a forced air heating system, and will require separate ductwork for your air conditioning system.
Hydronic Heating (Hot Water Baseboard) - Although this uses hot water heated by a boiler similar to an in-floor radiant heating system, the hot water is piped to baseboard units mounted along your walls which have fins that heat the surrounding air, which then rises to heat the room. Not every company licensed for HVAC does this so look specifically for hydronic heating contractors in Howard County MD.
Steam Radiant Heating - Cast-iron steam radiators can still be found in older buildings or homes but are rarely installed new anymore. They tend to be considered bulky and unsightly by modern standards and can be replaced with vertical wall panel radiators, such as are often seen in apartments.
Geothermal Heating - Geothermal heating and cooling in the form of a GHP (Geothermal Heat Pump) is the newest technology. Geothermal heat pumps take advantage of the constant temperature several feet underground with water pipes running from a heat pump above ground to several feet below ground where it is cooler.
A GHP is more energy efficient than other systems can can save 30%-70% on home heating or 20%-50% on home cooling according to the EPA, but are 50-100% more expensive to install, with a 3-ton GHP system costing $5,000-$10,000 more than a heat pump system that runs on air.
With an annual energy savings of $350-$1,500, it can be many years before the additional expense of purchase and installation is recouped. Ask your local HVAC contractors in Howard County MD how much experience they have with GHP systems and how much in annual energy savings has been experienced by their customers in your area and climate.
