When looking for a great Commercial HVAC company in Maryland you will want to consider a few questions. Partnering with a highly qualified HVAC contractor will mean more peace of mind, preparation, communication and results. Investing into your commercial building with quality HVAC can mean reduced utility bills, consistent comfort and more productivity from your staff, customers and impressing guests and important visitors. As a leader in the Commercial HVAC world we are proud to partner with many businesses in their heating and cooling needs from their commercial Heating and Cooling systems.
The ACCA or “Air Conditioning Contractors of America Association” has provided a good starting point of questions that will help building managers and/or owners to be informed in their relationship with their HVAC partners in Central Maryland. Here are a few questions to help you before, during and after your Commercial HVAC process. Source http://www.acca.org/
- Was a load calculation undertaken for your building? To install the right size unit, contractors need to know the building’s heating and cooling requirements, based on a variety of factors (e.g., ventilation needs, size of the building, type of windows, insulation amounts, etc.). Determining heating / cooling loads based on the building’s square footage is inaccurate and inadequate. Also, basing replacement equipment on the size of the original system could lead to problems since the original equipment size may have been incorrect.
- Did the Commercial HVAC contractor review the manufacturers’ performance data with you to demonstrate why the unit you’re buying is the right size? The load calculation (from Question 1) guides proper equipment selection. A unit that is too big (oversized) may have a higher upfront cost, raise your utility costs, remove less humidity, and fail more quickly.
- Did the contractor present proof that the system will deliver the specified
efficiency based on AHRI certification? Equipment which has not been tested by an independent organization or is not designed to work together may not deliver the promised
high efficiency performance
- Did the contractor review the condition of your duct system with you? (Does not apply to boilers or new construction) Leaky ducts can cause health problems and waste energy. Also, if the ducts are too small they will cause the HVAC system to use more energy and/or deliver less comfort. Small ducts may also lead to early equipment failure.
- Did the contractor review the condition of your current furnace’s or boilers venting system with you? (Does not apply to A/C, or heat pumps, or new construction)When fossil fuel is consumed, combustion gases are produced. If these silent threats are not removed by the vent system, you could suffer grave health problems. Note: Other gas appliances (e.g., dryers, water heaters, kitchen equipment, etc.) also need proper venting.
- Will the HVAC contractor measure and document the airflow? (Does not apply to boilers)If the furnace, air conditioner, or heat pump does not have the proper airflow, the unit will waste energy, may create health and safety problems, may fail to keep you comfortable, and may cause the unit to fail more quickly.
- Will the contractor measure the refrigerant charge? (Does not apply to furnaces or boilers)If the refrigerant charge is not within the tolerance of the QI standard, then the unit cannot deliver the full energy savings and system performance
- Will the contractor ensure the unit is safe electrically?
The fuses, wiring, and circuit breakers must be correct for the unit being installed. Replacement equipment may have different requirements than the existing system.
- Will the HVAC contractor test the firing rate of the new furnace or boiler? (Does not apply to A/C or heat pumps)The contractor needs to measure, and possibly adjust, the firing rate to ensure proper operation.
- Will the Heating and Cooling contractor test the venting system for the furnace or boiler? (Does not apply to A/C or heat pumps)The contractor needs to verify that all of the combustion gases are vented outside your building.
- Will the HVAC contractor test the thermostat? The contractor needs to ensure that the unit operates properly in all modes and that the thermostat is fully compatible with the new equipment.
- If ducts are new or are to be repaired, did the contractor state how they will measure the duct leakage after completion?The contractor needs to test to be sure the warm and cool air you are paying for is entering your building and not escaping into unconditioned spaces. This is especially important when ducts are located in unconditioned space like the roof, an attic, or crawlspace.
- Will air (A/C, furnace, and heat pump) or water (boiler) testing and balancing be performed?The contractor needs to measure the conditioned airflow and/or water flow (for hydronic applications) flowing into each room to ensure that each room receives the appropriate amount.
- Will the contractor provide a copy of the installation checklist with a record of all measurements taken during installation?These benchmark measurements will be used by future technicians to ensure that the equipment continues to perform as it should.
- Will the contractor provide a copy of the owner’s manuals, manufacturer’s warranty, and their warranty?These documents provide valuable information for warranties, future maintenance, or repairs. You should know what the manufacturer and the installing company will do in the event of a problem.
- Will the Commercial HVAC contractor provide a copy of the recommended maintenance requirements for the new equipment? If a maintenance program is offered, it should inform you of the components inspected, time frames for inspection, and other factors involved. These requirements are explained in the national standard for commercial HVAC maintenance (ASHRAE/ACCA 180 Maintenance of Commercial HVAC Systems)
