HVAC systems are a great investment for the clients of HVAC Companies in Pakistan. We’re not just talking about the initial cost of buying and installing equipment, but also how much you’ll be spending on utilities over the years. Statistics show that you will be spending over $2000 on utilities alone this year. HVAC systems accounted for nearly half of the energy consumed in the home during that period. Your home, old or new, consumes a lot of energy. Whether you are upgrading an existing HVAC system or installing a new HVAC system in a new home, here are some tips for choosing the right size system to ensure energy efficiency.

So What Can You Do To Prevent Your Home From Absorbing Too Much Energy?

First, understand that if your hardware is old, it’s time to replace it. Equipment over 10 years old is very inefficient and is best replaced with a more energy efficient (i.e. Energy Star certified) model. When purchasing any type of HVAC equipment, it is wise to choose an energy-efficient model.

Now, this begs the question of why size matters in the case of HVAC. It is important! Choosing the right sized equipment (and thus the appropriate heating/cooling output) has a direct impact on the comfort, efficiency of the HVAC system, and maintenance and operating costs. It is evident how much this topic is wrongfully ignored. In fact, it is estimated that more than half of the HVAC Companies in Pakistan are not sizing HVAC systems correctly.

Mistakes In Selecting HVAC Systems

Oversizing is one of the most common mistakes. Scaling up an HVAC system can affect many areas within a process. For example, the installation will cost you a lot more money. Large-scale systems tend to be more expensive to operate, break down more frequently, operate inefficiently, and require more maintenance. Large-volume air conditioners tend to shut down before moisture is removed from the air properly. The result is a damp environment prone to mold growth. Large ovens produce uncomfortable fluctuations in temperature.

When HVAC Companies in Pakistan try to scale the system, they don’t read labels or simple standards. Instead, the computation should be multivariate and include situation-specific factors. For example, what is the weather like in your area, how many windows and how big are they? What is the amount of insulation and what type of insulation? How big is your house? Does the house have one floor or 2? How long have you been sneaking outside? How many residents are there?

Industry Standards of Sizing

There are two industry standards that help determine the right size for your system. The two “Manual J” and “Manual D” were produced by an American air conditioning contractor. Manual J, also known as “Home Load Calculator”, is mainly used to determine HVAC volume calculations. Reputable HVAC companies in Pakistan will say to use Manual J for sizing. The D brochure, also called “residential duct design”, is used to size ducts. When looking for a company to help you install your new HVAC system, be sure to check if they use manuals J and D for their sizing and installation process.

The topic of this article focuses on the size of the HVAC for your home. Your home is an energy hog! New homes, old homes, renovated homes. They all lose energy! HVAC systems account for 46% of your annual energy consumption, making them the most expensive investment to improve your home’s energy efficiency. Buying and replacing is probably the least understandable of all the improvements to your home.

Old HVAC Systems VS New HVAC Systems

HVAC systems that are 10 or more years old are often unreliable and significantly less efficient than modern systems. When replacing a new HVAC, choosing one of the correct volumes (heating and/or cooling output) will yield the highest efficiency, comfort and lowest maintenance and operating costs over the life of the new system important to many reputable national surveys show that more than half of HVAC Companies in Pakistan And air conditioning are not sizing their heating and cooling systems correctly.

System scaling is the most common scaling error. It makes installing large-scale HVAC systems more expensive, requires less efficient operation, more frequent failures, and higher operating costs. Large ovens often cause large and uncomfortable temperature fluctuations in the home. Air conditioning units that are large enough to remove moisture from the air do not work, which is why many air-conditioned homes are “damp”, and it can cause a feeling of worn out and unhealthy mold growth.

Conclusion

The correct size of an HVAC system requires consideration of many factors beyond simply reading the nameplates on existing units. Key factors for determining the correct size of an HVAC system include microclimate, current or future insulation levels, window information (area, location, and type), home information (size, shape, and orientation), air permeability (using an identifiable blower door test), number and age of occupants, and types of lamps. And appliances in your home that can generate heat.
