Oversized Heat Pumps: A Recipe for Mold, Discomfort, and High Energy Bills
Throughout the HVAC industry, the push for decarbonization is driving a surge in heat pump installations – but there’s a catch: oversizing! As highlighted in the June 17th edition of ACHR News (“Sizing Heat Pumps for Colder Climates“), oversized heat pumps lead to inefficiency, poor humidity control, and uncomfortable, mold-prone environments.
But there’s a solution: the APR Control!
The Problem with Oversized Heat Pumps (How and Why)
The HVAC industry has long grappled with the issue of oversized heat pumps, particularly those often sized for peak heating needs in colder climates. This normally results in excess cooling capacity.
The article points out: “I keep hearing people [Contractors] say, put in one of these inverter systems and size it however you want, and (think) the cooling will be fine. If you live in 80% of the country that has green grass or humidity, it’s not necessarily going to work properly” (Janowiak).
In most regions of the United States, peak cooling demands are infrequent as real-world conditions rarely match design conditions, leaving these oversized systems to short cycle throughout most of the year. This not only fails to adequately remove humidity, creating a prime breeding ground for mold, but also leads to unnecessary wear and tear on the system, ultimately shortening its lifespan.
To compensate for the discomfort caused by poor humidity control, end-users often rely on supplemental heating solutions like electric, gas, or oil. However, these options come with a hefty price tag, adding to equipment and installation costs while driving up energy bills.
The APR Control Solution to Oversized Heat Pumps
Oversized heat pumps, often chosen for worst-case, highest load heating scenarios, can lead to inefficiencies and discomfort during milder weather. The addition of the APR Control offers an effective and reliable solution, dynamically modulating capacity to match actual cooling loads without compromising heating performance.
This means:
- No more oversized headaches: Enjoy efficient, balanced cooling in humid or even milder climates.
- Goodbye, humidity: Say farewell to mold and mildew caused by poor moisture control.
- Consistent comfort: Experience stable temperatures and a healthier indoor environment.
- Longer equipment life: Reduced wear and tear means your heat pump will last longer.
It’s important to emphasize that the APR Control only operates during cooling mode and never impacts heating capacity, allowing heating capacity designed to always be delivered. This ensures year-round comfort and efficiency, making it an ideal choice for heat pump systems prone to extensive part-load operation.
The APR Control delivers comfort, efficiency, and cost savings for your customers, with a proven track record of over 30 years in optimizing oversized air conditioning & heat pump systems. Don’t let oversized heat pumps compromise your clients’ comfort and well-being. Choose the APR Control for optimal comfort, efficiency, and peace of mind from that dreaded clammy feeling.
The Future of Heat Pumps in the HVAC Industry
As all-electric heating and cooling become the norm, the APR Control (mechanical or electronic) is essential for maximizing heat pump performance. It’s the key to unlocking true comfort, efficiency, and sustainability.
