St Louis’s Home Performance Experts, Ventilation, Energy Audits, and Comfort
The traditional approach just doesn’t work
If your bedrooms are too hot or your basement is too cold, upgrading to a higher eficiency unit is not going to fix the problem. Our team at Greenmark Home Performance knows that most HVAC contractors focus on replacement units because it is quick and profitable for them. We understand that home comfort starts with a whole home approach, investigating the cause of your uncomfortable home rather than just replacing your HVAC Unit.
An uncomfortable home is not a sign of a failing HVAC unit. More likely it is a sign of other issues with your home like poor insulation, drafts, and improper ventilation.
Our team works with homeowners across the St. Louis area to provide real solutions to their uncomfortable homes. Contact our experts to schedule a home performance audit today.

Most homeowners immediately jump to poor insulation or a bad HVAC system as the reason for comfort issues in their home. Our team at Greenmark Home Performance knows that this is rarely the case and can lead to services that won’t solve the problem. Most home comfort issues are due to poor air sealing, duct sealing, insulation problems, drafts, and poor indoor air quality.
Ventilating a bathroom is important. It is a job best performed by professionals as proper setup of the ventilation system will involve installing an external exhaust system which could damage your home if installed by yourself.
Poor duct sealing, drafts, and poor insulation are the primary cause for temperature differences between rooms.
Poor air circulation and ventilation can leave you with dry and stale air around your home. Installing a humidification system and whole home ventilation system can help solve low humidity issues.
The average HVAC replacement costs between $4,000 and $12,000 depending on the size of the home. If ductwork needs to be replaced, you can expect additional charges.
Poor indoor air quality can lead to excess allergens and pollutants inside of your home.
The best ways to improve indoor air quality are to install a whole home ventilation system to completely change the air inside of your home and to ensure that any drafts in your ductwork or windows are properly air sealed.
There are a variety of ways to save money on your energy bill including replacing existing lighting with LED, preventing heat seep (heat loss due to poor air sealing), and ensuring that your home is properly insulated.
The short answer for this is because hot air rises. In a two-story home your HVAC system needs to work twice as hard to cool the upstairs due to the warm air rising within your home.
Installing a whole home insulation system will improve the air quality inside of your home. This is because it will completely change the air within the home several times throughout the day. It can also be used to circulate conditioned air around your home more efficiently.
No, an attic fan uses negative pressure to change the air in your home. It lifts and expels air pollutants and allergens and pulls new fresh air from the outside of your home. You should run an attic fan with the bottom floor windows open.
Most homeowners will live in a home for years without getting the ductwork cleaned. Our team at Greenmark Home Performance recommends getting your ductwork cleaned at least once per year. Over time dust, allergens, and indoor air pollutants will build up inside of your ductwork.
Insulating your home is important spray foam and cellulose insulation are the two most common types of insulation and both serve different purposes. Spray foam insulation is great for sealing and insulating small or tight areas like inside of walls and tight attic spaces. While cellulose insulation is great for building up a high insulation rating for your home. Cellulose insulation is commonly used in attics because it is easy to install and will keep your home insulated for years.
The best way to make your home more comfortable is not to call your HVAC company. Hire a reputable home performance company to perform an energy audit on your home to determine which areas may be making your home uncomfortable and costing you money.
Drafty windows need to be air sealed. This involves removing the caulking and sealing the space in between the window and the wall, then replacing the caulking. This should keep drafts to a minimum. In some cases, the draft may be due to a window fault. The only solution for this is to replace the window.
Most home ductwork is uninsulated and was installed before building code required sealing. Todays codes require that all ductwork be properly sealed to prevent heat loss. Having your ducts sealed is relatively simple and will save you money on your energy bills.
