The Best Heating & Air Contractors in Harford County MD Are the Ones Proven Safe To Hire

The state of Maryland requires a state license of contractors for ventilation, heating, and air conditioning in Harford County MD,  which requires a minimum amount of experience and training, and passing an exam with a score of 70%.

But the state license for HVAC contractors is no guarantee that any particular heating and air conditioning contractor in Harford County MD is doing business honestly, providing real value, or satisfying customers.

This makes it all the more significant that all all heating and air conditioning contractors in Harford County MD who bear The Prime Buyer's Report Top Ten symbol have been cleared by our research staff as passing all the requirements for Prime Buyer's Report Top Ten status.

HVAC Contractors in Harford County MD Provide Numerous Heating & Air Conditioning Services
Heating, air conditioning, and ventilation contractors in Harford 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 Harford 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 Harford 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 Harford 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 Harford 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.

Heating Systems

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 Harford 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 Harford 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.

Questions To Ask Heating & Air Conditioning Contractors in Harford County MD

Step 1: Know What You Need From the Best HVAC Contractors in Harford County MD
Explain what type of heating, air conditioning, and ventilation work is involved. Since you aren't the contractor, it's understood that you have limited knowledge of your HVAC system. In this case, your description should basically include any problems you've encountered and your climate preferences.

Be consistent in the way that you present the information so each heating, air conditioning, and ventilation contractor will have an opportunity to offer an equally informed time and cost projection for your job.

Step 2: Answer Questions from Good Heating, Air Conditioning & Cooling Contractors & Take Notes
Listen carefully to the questions each HVAC contractor asks. Document the varying concerns of each professional heating, and air conditioning contractor. Note the level of detail and the amount of time he's willing to devote to you. It will help you assess his proficiency and work ethic.

Step 3: Questions to Ask Heating, Ventilation, Air Conditioning Contractors

• How long have they been doing HVAC in Harford County MD specifically? (Different regions have their own unique weather that will effect choices in equipment and installation method. The length of experience doing heating & air in your location specifically shows familiarity with these aspects.)

• Will they provide a written estimate that is detailed, including brand names and product numbers of the equipment, as well as the type of material and amount used for installation? (This is key because cheap HVAC contractors in Harford County MD often only seem cheaper because they are skimping on labor, materials, or are quoting an inferior unit.)

• What are the manufacturer warranties on any new unit to be installed?

• Do they provide a written warranty for their labor, aside from manufacturer warranties and can you see it?

• Will permits be needed? If so, will the contractors be responsible for getting them or do they leave that up to you?

• Can the company show that all employees sent to your property are legal to work in the U.S.? (All HVAC contractors in Harford County MD bearing The Prime Buyer's Report Top Ten symbol have already signed an obligation to only hire documented workers.)

• Will they show you proof of active workers' compensation and liability insurance? (All heating & air companies in Harford County MD bearing the Prime Buyer's Report Top Ten symbol have already had proof of insurance verified by our research staff so you don't have to.)
