AUGUST 17, 2023

In the sweltering summer heat, nothing is more refreshing than walking into a cool, air-conditioned home. But what if you’re in the market for a new air conditioning system? It can be overwhelming with so many options and technical terms flying around. No worries!

1. Measure and Inspect Your Old Air Conditioner System

Before diving into the world of new air conditioning units, taking stock of your current setup is crucial. This involves:

– Checking the age and efficiency of your existing unit.

– Evaluating its performance – does it cool effectively and evenly throughout your home?

– Examining the physical condition for signs of wear and tear, including potential leaks or damages.

By understanding where your old system stands, you can better judge what you need from a new one.

2. Square Footage of Your House

Size matters when it comes to air conditioning. A unit that’s too small won’t adequately cool your home, while an oversized unit will cycle on and off too frequently, increasing wear and wasting energy.

Here is a simple breakdown of which size system should be used for your home:

A/C Tons:

800-1200 sqft = 1.5 ton

1201-1550 sqft = 2.0 ton

1551-1900 sqft = 2.5 ton

1901-2150 sqft = 3.0 ton

2151-2450 sqft = 3.5 ton

2451-3000 sqft = 4.0 ton

3001+ sqft = 5.0 ton

3. Determine HVAC Loads & Equipment Sizes

With the size of your home in hand, the next step is to compute the HVAC load. This involves a detailed analysis, considering factors like:

– Insulation levels.

– Window sizes and types.

– Orientation of the home (which direction it faces).

– Local climate conditions.

Once the load is determined, it’s easier to pinpoint the equipment size that’s just right for your needs. This ensures maximum efficiency and comfort. Harmonic HVAC can have an expert team member on-site to figure out all these details!
