HVAC Companies in Pakistan Provide Energy Efficient Solutions

About 30-40% of the electricity bill. This is the amount it costs the average homeowner or commercial building owner to provide HVAC. A healthy HVAC system is a key to maintaining a comfortable and healthy indoor environment. Over the years, many owners have asked me about strategies to reduce energy and air conditioning costs. They do not want to sacrifice internal environmental conditions but want to follow a detailed plan. Interestingly, get significantly reduced utility bills, and the performance of the HVAC system improved. This is a standard feature for HVAC Companies in Pakistan specializing in power and air conditioning. This page helps homeowners, building owners, and building operators make informed decisions about current HVAC systems or future upgrades.

System Optimization

The first step in achieving power and HVAC system optimization is to reduce the load. This step usually consists of a long-term plan detailing actions mapped out by HVAC Companies in Pakistan based on the best return on investment. Reducing the burden on your building allows your existing HVAC system to operate more efficiently. If a new system or multiple systems are considered, it is more cost-effective to design a load less than the current load. Common burden reduction strategies include:

Tighten the building structure and add insulation. In some cases, adding insulating materials to an existing building may not be possible. It is best to pay attention to the exterior, especially the windows and doors.

Install energy-saving windows. This is an essential element in some buildings that still have single-pane windows. Installing insulated double-glazed windows is an excellent return on investment. Make sure your windows are ENERGY STAR certified. Tinted or low-emitting paint is better.

They have an upgraded lighting system

The average lighting intensity for a commercial building is 2-3 watts per square foot to maintain proper lighting levels. This is an essential part of the HVAC load, and most efforts in this direction reduce the building’s cooling requirements. Accent lighting (sometimes called architectural lighting) is not always energy efficient and should not be considered if you want to reduce energy and air conditioning costs. Energy-efficient lighting systems emit less heat in an air-conditioned space than older incandescent technology. If you have a supplemental return air instead of a return air duct, consider a troffer light so that some of the light’s heat is returned to the HVAC system rather than into the occupied area.

Choosing efficient electronic equipment and appliances with energy-saving options will reduce good heat build-up in your space—photocopy machines, kitchen equipment, personal computers, refrigerators, etc. Balance the outside air and control the ventilation. Most building owners have drawings for the original HVAC installation. Did the HVAC Companies in Pakistan review the images to ensure that the external airflow complies with the latest code requirements? Even if graphics are not available, mechanical engineers can make recommendations for improvement. Addressing these elements is the first step in reducing energy and air conditioning costs.

Air Conditioning System

Knowing your system is the second step in achieving HVAC system optimization. HVAC systems are essential to indoor climates and represent a large portion of your utility bills. A description of all plans is outside the scope of this article, but you can address some recommendations. All components of the HVAC system have improved efficiency over the years. If your system is over 13 years old, it’s time to start planning an upgrade to the latest equipment. The average life of a well-maintained housing system is about 15 years, but it seems to fail at worst. Have your replacement plan ready for the day your hardware fails.

Commercial systems vary, but you can expect the same longevity if the building uses packaged equipment or split systems. HVAC systems can become more complex for large commercial and industrial applications and require individual analysis by mechanical engineers of HVAC Companies in Pakistan. As mentioned earlier, HVAC systems are different, and a one-size-fits-all study does not work for large systems. All these systems have in common because they usually run on electricity. Electricity costs money, so efforts to improve efficiency are an added advantage.

HVAC System Tips:

Find a trusted and qualified advisor. If you are a homeowner or owner of a small commercial building, find good HVAC companies in Pakistan or mechanic to evaluate and maintain your system. If you are a prominent commercial building owner, find a commercial HVAC general maintenance company and an excellent mechanical engineer for specific guidance. We do not recommend the use of a mechanical engineer working for HVAC. Find an unbiased third-party engineer for an honest opinion.

Check the load of the HVAC system. Homeowners must use ACCA’s Manual J calculation method, and all other homeowners must have their bags done by a mechanical engineer. Commercial buildings have more requirements related to code compliance, minimum ventilation, etc., and are individual for each building.


Choose the size of the equipment to carry. Never inflate! The “more is better” mentality does not apply to HVAC systems. It costs not only to purchase equipment but also to operate it. Get your payload and equipment choices the first time.

Purchase high-efficiency equipment or Energy Star. Many newer systems include variable speed drives for fans and compressors. With years of ownership, this will pay off many times over. Compare standard and high-efficiency equipment in terms of up-front and life-cycle costs. Any good HVAC companies in Pakistan or mechanical engineer can get this information.

Energy Saving

Consider energy recovery for the air leaving the building and use it to condition the fresh air coming in. This is the air you paid for in the air conditioning, so your priority should be to extract some energy before it runs out.

Consider outdoor air conditioning with a dedicated outdoor air unit in more significant commercial buildings. This eliminates the problems associated with moisture control in most cases. It also improves passenger comfort and allows for further equipment miniaturization.

Commercial premises should take into account the equipment economy. Most current codes require economizers to be installed on equipment over 15 tons. Often available at a low additional cost, these units draw fresh air from outside when the outside temperature (and possibly humidity) is lower than the indoor temperature.

Homeowners and owners of small commercial buildings should install programmable thermostats. Commercial building owners must install a Direct Digital Control (DDC) system. Investing in any of these things will pay off more than the cost in the short term. See below for details.

Control System

System control is the third step in achieving power and air conditioning system optimization.

Programmable Thermostat: The digital control era has made saving energy easy. A programmable thermostat is one of the best investments for homeowners or small commercial building owners. They are easy to use and can include strategies based on time scheduling. Most manufacturers offer a 7-day setback/setup programs to turn the HVAC system on and off to complete your schedule and the desired room temperature. This is a great way to ensure that your HVAC system is used only when needed.

DDC Systems: For large commercial buildings, I think this is a must-have system. Installation costs are steadily decreasing, and performance reliability is steadily improving. It can be integrated into any system and expanded as needed. Some of the most common features of these systems are HVAC plans start/stop, multiple zone control, multiple temperature sensor locations, and ventilation control. The best thing about these systems is that they can be scaled up to the most significant commercial applications. You can install a simple system and add controls later to integrate the entire HVAC system. Again, the payoff is short and well worth the investment.

Operating and Maintenance

Operations and maintenance are the fourth and final steps in achieving HVAC system optimization. Efficient HVAC systems have one thing in common. They are well maintained. Follow these tips to ensure your HVAC system’s reliability, efficiency, and longevity.

Find a trusted and qualified advisor. If you are a homeowner or owner of a small commercial building, find a good HVAC company or mechanic to evaluate and maintain your system. If you are the owner of a large commercial building, look for a commercial HVAC contractor for regular maintenance. Record all services and record the service person’s date, time and name.

Homeowners should always have a seasonal adjustment. The behavior of the system depends on the season of the year. Replace the air filter regularly. To ensure dust and fiber removal, use only MERV 5 filters. A cleaner filter that saves fan power.

Coil Cleaning

This is an essential item that residential and commercial building owners always overlook. Condenser coils, being outdoors, collect dirt and debris on their surfaces. This makes the compressor work harder and overheats the coolant in the refrigeration system. Evaporators and heating coils collect dust and fibers that spread over your home or building. Clean at least once a year
