If you need HVAC performance testing, we're here to help!
Whole House Performance Testing in Maryland, Pennylvania, and West Virginia
Do you know how efficient your home is at generating and distributing heated or cooled air? Do you experience drafts in certain rooms? Are there any fixtures or appliances that could be upgraded to save you money? Most homeowners don’t know much about their home heating and air conditioning systems, which is unfortunate because a few simple upgrades can often save you hundreds or even thousands of dollars in energy costs each year.
Larry & Sons Plumbing, Heating & Air Conditioning offers whole house performance testing service as part of our indoor air quality services for customers in the Hagerstown, Frederick or Middletown, MD area. This service allows you to learn exactly where the weak points are in your home comfort system, where you can save money and how to ensure you stay comfortable throughout the year.
HVAC Performance Testing



Whole house performance testing is designed to ensure you know exactly what you’re getting out of your home comfort systems. For that reason, we provide a very detailed analysis of your home’s performance from top to bottom, including:
- Air Conditioning
- Ventilation
- Heating
- Air Filtration
- Energy Consumption
- Insulation
The most common problems discovered during performance testing are poor insulation and improperly sized heating and cooling systems. Because insulation requirements have changed so dramatically in recent years and technology has advanced rapidly in the wake of higher AFUE furnaces and higher SEER air conditioners, we can now minimize the amount of energy lost in the summer and winter with a relatively simple upgrade.
Additionally, we seek ways to improve your energy consumption. Do you have a furnace that is more than 15 years old or an air conditioner more than 10 years old? The odds are that it is using more energy than necessary. A replacement can drastically improve your energy consumption and save you money on your monthly energy bills.
Performance testing will reveal the approximate savings you stand to gain if you upgrade to an efficient modern system. If the heating and air conditioning systems you currently have are too small or too large, we will determine how much of an adjustment is needed for optimal comfort and cost effectiveness. Finally, we look at ventilation and make sure the heated and cooled air being pumped in to your home is clean and fresh. Energy recovery ventilators are a common upgrade for homeowners intent on maintaining low energy bills while ensuring healthy air.

Just bought my house literally a week ago and have already met 3 of your wonderful technicians (2 heating and 1 plumbing). They are polite and personable, and I feel like I can trust that they are doing what is best for my home… not just for the company’s bank account. That is difficult to find in any type of Service Company. Thank you!
Josh was wonderful. We just bought a house that needs a lot of work, and the heating systems were no exception. He looked everything over and gave me several options for the amount of work that needs to be done. I felt he was honest and sincere in his diagnosis of my many issues, and in trying to figure out the best options, while still remaining economical. He was very polite and personable as well. Thanks Josh!
