Heat and Energy Recovery Ventilators in Littleton, CO

Fresh, clean air is a key characteristic of comfort, but it’s not always so easy to achieve. This is especially true as you run your heating and air conditioning systems, recycling the same air over and over again. An air filter helps to get some particulates out of the air as you run these systems, but that doesn’t stop the smallest particles and, frankly, the odors in the air.

For this, you have two options. You could open a window to get rid of the stale air and let in all of the heat or chill you’ve been trying to keep out. Or, you can have our experts install a heat recovery ventilator (or energy recovery ventilator) and ensure your home gets fresh, clean, properly heated and cooled air all year round! Contact Southwest Heating and Cooling today to improve your indoor air quality in Littleton, CO.

Got Stale Air in a Stuffy Home?

It’s important to keep your home closed up tightly as you use your heating and air conditioning equipment. This is the only way to ensure that your furnace and AC systems run as efficiently as possible, as open windows will force a system to work much harder, raising your bills.

However, this results in stale air recirculating throughout your systems over and over. When you walk inside, straight from the fresh air, you may say to yourself, "It’s stuffy in here". But what can you do without opening the window, changing the temperature, and raising your energy costs?

How Heat Recovery Ventilation Works

A heat recovery ventilator (HRV) is a way to bring fresh air into the home by the most efficient means possible. The fan draws stale air from your home and moves it to the outdoors, while bringing fresh air from outside into the house.

If this were its only function, an HRV would be highly inefficient, as it would bring in cool air in the winter and warm air in the summer. But an HRV also contains a heat exchanger. This allows incoming fresh air to be preheated by exhausted stale air in cold weather. And when you use the air conditioning, the heat exchanger allows heat from the incoming fresh air to be exhausted outdoors with the stale air.


For the most part, a heat recovery ventilator and energy recovery ventilator (ERV) do the same thing. An ERV system is actually a type of heat recovery ventilator, but it has one additional function a standard HRV system lacks. An ERV is able to maintain humidity levels as well. This is important if you live in a particularly humid or a very dry area and want to keep moisture out—or in. Our experts can help you find the right system for your home.
