We approach every Heating and Cooling design and installation with an open mind, taking in every aspect of the site with our eyes, and listening to all your requests, concerns, and questions. As professionals, it’s our utmost goal to meet your expectations, but never by sacrificing quality. Honesty is always the best policy, and if we feel that a particular request won’t be appropriate or cost-effective, we’ll suggest alternatives or modifications that will work for your tastes and property. We have experience in most design styles, but some of our specialties include:
- Air Conditioners
- Heat Pumps
- Furnaces
- Fan Coils
- Ductless Mini-splits
- Thermostats
- Electronic Air Cleaners
- UV Lights
- Humidifiers
- Dehumidifiers
- Zoning Systems
The goal for a HVAC system is to provide proper air flow, heating, and cooling to each room.
An HVAC system should:
- Be properly sized to provide correct air flow, and meet room-by-room calculated heating and cooling loads;
- Be installed so that the static air pressure drop across the handler is within manufacturer and design specifications;
- Have sealed supply ductwork that will provide proper air flow;
- Be installed with a return system sized to provide correct return air flow;
- Have sealed return ductwork that will provide proper air flow to the fan, and avoid air entering the HVAC system from polluted zones (e.g., fumes from
- autos and stored chemicals, and attic particulates);
- Have balanced air flows between supply and return systems to maintain neutral pressure in the home;
- Minimize duct air temperature gain or loss between the air handler and room registers, and between return registers and the air handler;
- Be properly charged with refrigerant;
- Have proper burner operation and proper draft.
- Procedures to Design and Install an Air Distribution System
The following steps should be followed in the design and installation of the HVAC system to ensure efficiency and comfort:
- Determine room-by-room loads and air-flows using ACCA Manual J calculation procedures (or substantially equivalent);
- Layout duct system on floor plan, accounting for the direction of joists, roof hips, fire-walls, and other potential obstructions. Determine register locations
- and types, duct lengths, and connections required to produce layout given construction constraints;
- Size duct system according to ACCA Manual D calculation procedures (or substantially equivalent);
- Size HVAC equipment to sensible load using ACCA Manual S procedures (or substantially equivalent).
