When you’re installing a new HVAC unit, it’s important to make sure the unit is correctly sized.

Every family is unique and each home is diverse, which is why each family has distinct design needs for their home’s heating and cooling system. Our technicians adhere to industry standards written in ACCA‘s design manuals. Room-by-room heat loss and heat gain is a calculation heating and air conditioning technicians use to address the energy and comfort needs of your home before you buy a new heat pump and air conditioner. Keep your family comfortable by installing the unit correctly and so you won’t have to ask,  what size heat pump do I need?


“What size heat pump do I need?”


First, you need to find out what a room-by-room heat loss and heat gain is and how it affects the size of your heat pump.


Room-by-room heat loss and heat gain

When your HVAC system is too large for your home, you’ll pay more to feel less comfortable. Oversized equipment operates in short run time cycles, so it’s on long enough to cool your home, but not to pull the humidity out. Don’t allow your HVAC tech to assume that your home just needs a replacement of the same sized unit. Any time you build additions or even just improved the insulation, your home may require a new sized HVAC unit. Plus, you wouldn’t want to assume that whoever installed the current unit did it correctly the first time. Make sure your, heat pump or air conditioning, technician agrees to take the time to calculate your home’s most up-to-date heating and cooling needs using the industry standard calculation. Such calculations take into account the climate, along with the house’s size, design, and construction.


Replacing your heating and cooling system

Free HVAC design consultation

Leinbach Services will install your new HVAC system correctly so you can notice the increasing amounts of efficiency and comfort. When we come to your home or office for your free design consultation, we’re going to inspect your current system and talk about how we can increase the performance of your home. Here’s exactly what we’re looking at:

1. Properly designed and sized unit:

We’ll determine the correct size of the unit for your space in order to optimize the unit’s performance. Ultimately, the best path to comfort and savings is finding an air conditioning unit that actually fits your home. One that isn’t powerful enough won’t effectively cool your home and will inflate your power bill. One that is too powerful will work too quickly, shutting off before most of the humidity has been removed, leaving you cool but clammy.

2. Evaluate and improve ductwork:

Leaky ducts waste energy and money as it reduces the amount of conditioned air flow. We’ll inspect your ductwork by testing for leakage, then based on that information, we’ll talk about making necessary repairs to meet or exceed performance standards.

3. Optimize airflow:

Certain seasons encourage high levels of humidity, so by supplying a constant supply of ventilation, you’ll free the air from excessive amounts of moisture in the air. Lack of humidity control in our local humid climate can lead to mold growth causing moisture-related health problems.
