Homeowners, you don’t need to settle for heat or cool discomfort in your home when there are many options to either correct or supplement your home heating and cooling system.
First, how did it get that way? Perhaps you just bought a new home. Assuming the windows, doors, and walls are properly insulated and you still have hot and cold areas, depending upon the season, it may be a ductwork issue. A heating and cooling system design should consider the size of equipment and size and location of ducts and registers for each level of the home. If a room has a cold spot, it may be that the trunkline (metal ducts attached to the ceiling of the basement) was not designed to consider air velocity. Heating and cooling installers can measure the amount of air going to various registers. Some industry heating and cooling installation best practices include:
- Duct system design should consider the whole home heating and cooling distribution, including calculation of the airflow pathway.
- Calculation of heat loss to ensure a heating and cooling system is sized correctly. A system that’s oversized will not save you money.
- Return air system is hard ducted and sealed, depending on the location of the air duct.
- Elimination of building cavities or addition of airtight sealing on floor joists and studs typically used in traditional construction.
- Knowledge that the use of building cavities for return air can result in air quality problems, higher energy usage, and building structure failures.
- Usage of transfer grills or jump ducts to ensure return air from all rooms.
The benefits of proper installation of a heating and cooling duct system during the construction phase are great and will provide lasting comfort and energy efficiency.
Ways to Improve an Existing Ductwork System
Once ductwork is installed, it can be difficult to change, but there are things we can do to improve the system airflow.
Here are some options:
- Increase return drop for better air distribution.
- Install a zoning system.
- Use ductless mini splits for areas of the home that do not have ductwork.
If you’re building a new home, require the builder to ask heating and cooling contractors the following:
- Are they licensed and insured?
- How much experience do they have in the industry?
- Do they have references?
- Do they guarantee their work and offer warranties?
Request a quality installation with a heating and cooling contractor who has experience with the brand that is being installed.
