Improving AC efficiency-DIY tips and tricks- Part 2

These are the tips and tricks for improving your Air Conditioner’s efficiency without having to call of wait for your nearest Houston HVAC contractor or technician. In the last part we dealt with the condenser of your Air Conditioner which is located outside the house. Now it’s time to deal with the evaporator, which is located within your rooms of the house. The first and foremost thing to do is to either clean or replace the filter of the evaporator. What the evaporator does is suck in air from the room passing it through the filter and over the cool refrigerant in the process and throws back the cool air back into the room. This process repeats itself over and over again to maintain not only thermal comfort but also allow you to breathe cleaner air. In the process the filters get dirty. You may be wondering as to how this effects the efficiency of the Houston HVAC System? If the filters are dirty, it will the fan would be working harder to suck the same amount of air. Therefore it is always recommended to clean the filters every two weeks.

But what if you have not been so active in cleaning the filter. Here is what you can do. As always, switch off the electrical mains and unplug the air-conditioner so that you are safe from any electrical shock. Now you would want to lift off or unscrew the cover of the evaporator to expose the filters. Once the cover is removed, you can check the quantity of dust settled on the filters by just running your finger over the filter. Now you need to take out the filter and clean it using a hose or under running water. Make sure to gently rub it with the help of a brush to aid easier removal. You might also use some detergent as well. Once done you would want to let it dry in shade for some time.

Once dry you can then put back in the filter into the evaporator and screw back the cover. It is important that you do not run the without installing back the filter. For the climate of Houston you may also consider replacing the filters in the transition period of summer-winter and winter-summer.

The other things that you can do to improve efficiency during the cooling season is keep the operating temperature at an ideal 72° F and use a ceiling fan running at medium speed to circulate the cool air. You might also not want to place computers, televisions and other heat radiating devices near air conditioner thermostat, as it will impact the proper functioning of the thermostat and thereby make the air conditioner condenser work longer and consume more electricity.

Improving AC efficiency-DIY tips and tricks- Part 1

Its June again in Houston and the temperature is soaring. You switch on the air conditioner but somehow you feel that your home is not being cooled enough. You then think of calling your nearest Houston HVAC unit’s maintenance technician. But you find that all the guys are pre-occupied and you probably have to wait a day or two for them to come and do a systematic check. Worry not! Here are some of the easiest things that you can probably do it yourself. Please bear in mind that these steps should be carried out only if you have a basic knowledge of electrical and mechanical science.

First and foremost, make sure to switch off the electrical mains and unplug the air-conditioner so that you are safe from any electrical shock. Next you need to proceed to the condenser which is installed on the outside of your home. If the condenser is placed on the ground or at a height lower than 1 meter than you might go ahead with this step. Otherwise you might want to wait for your Houston HVAC technician. You would see two metal pipes (one sized about a quarter on an inch and another about half an inch in diameter), conjoined together. You might see that insulation is wrapped around the bigger pipe. With the passage of time, the insulation starts to decay and fall apart. This results in a drop of cooling performance of your Air Conditioner. So you could basically go ahead and wrap a new insulation around the bigger pipe and fix it using electrical tape or adhesive seal. It is very important that you do not wrap both the bigger and smaller pipe together. This is because, the smaller pipe carries the refrigerant taking out the heat from within your home to the condenser where it is then cooled. The cooled refrigerant is then sent back to the inside of the house or the evaporator in the bigger pipe. And therefore to prevent any heat loss, it is the big pipe which must be insulated. As shown in image below.

The next thing that you can do is to take a hose pipe and spray water on all the fins to remove accumulated dust particles and debris. You need to make sure that you have at least a couple of feet of clearance near the evaporator. If the evaporator faces the road side it might be even dirtier and then you can also use soap water to spray on the fins as shown in image below.

HVAC System Optimization & Servicing To Reduce Costs

Most of households and offices spend their 30-40% of their bills to provide proper heating, ventilating, and air-conditioning (HVAC). An excellent HVAC system is the main factor that ensures comfortable, healthy and conducive environment. Even so, people have been looking for ways to reduce the cost of energy and HVAC. The idea is to look for ways to minimize the energy cost without reducing the interior aspects. What people do not know is when HVAC system performance is improved, their bills on the energy would be reduced significantly. This is a common qualification of mechanical engineering specialized in energy and HVAC.

One way to perform HVAC system optimization and optimizing the energy usage is load reduction. This phase will need you and the specialist to make long term plan which itemizes the actions that would be taken based on best return on investment. By reducing the load of your building will make the existing HVAC system to be more efficient. If you consider to make replacements of your system, you should ensure that the new one would be more cost effective and designed for the reduced load as opposed to the current load. You could use these following load reduction strategies:

Tighten the building shell and add additional insulation

The process of additional insulation in existing buildings may not be possible for some instances, so you should pay more attention to the exterior shell, especially windows and doors.

Installing energy-efficient windows

This is quite big and is meant for buildings that still have single pane windows. The double pane windows with a thermal break installations is an awesome return on investment. It would be better if you have ENERGY STAR qualified windows. Tinting or Low-E coatings will do much better.

Upgrading lighting systems

Commercial building has the average of lighting density of 2-3 watts per square foot in normal lighting condition. This is one of the important elements of HVAC load and if you do something to improve this condition, it will also lower the cooling needed for the building. Accent lighting (or something we know as architectural lighting) are only energy efficient in some types, and syou should thik twice before installing if you want to reduce energy and HVAC costs. Energy-efficient lighting systems produce less heat into conditioned space than older incandescent technology. If your building uses return air plenums instead of return air ductworks, consider installing light troffers so you can make use of the heat from the lights by returning them to the HVAC system instead of going into the occupied area.

You can also control ventilation by having your outside air balanced. Most buildings have blueprints of the original HVAC system installation. You can review the blueprints to a mechanical engineer to make sure your outside air flow rates conform to the latest code requirements. If there is no blueprints, your mechanical engineer would still be able to give you recommendations for improvement. These are your first steps to reducing energy and HVAC costs.

Is Your Business HVAC System Adequate?

Figuring out if your system is adequate is actually pretty easy, but you are going to have to figure out if you have made the right choices for the system. You can actually bring someone into the building, and they are going to be able to see what is going on. They can help you with the process, and they can actually measure your house to see what it is going to be like when they handle all the different parts of the HVAC system.

They can make sure that the house is the right size for the system, and they can do the same thing the other way around. It actually pretty easy for people to take care of this, but you need to make sure that you have someone come and do the inspection so that you have all the right information about the system. They can tell you what is going on with the system, and they can recommend the next step for your building.

Key Factors To Consider Before Hiring An HVAC Contractor

Hiring a qualified HVAC contractor to work on your project can be a tough decision to make. When selecting a company for your school or business, you should keep in mind the following key factors. If a contractor you have found has some of the issues listed below, than you are better off moving on and finding another contractor.

Licenses And Experiences

Most states require HVAC contractors to have a license. Some may also require insurance and bonding to protect their workers and you, the client. Business and school projects are often large scale and you are much better of if the HVAC company is licensed by the state, is insured and bonded. This will protect you from any liabilities if injuries or damages occur on or to your property. If a contractor lacks license and insurance, you should avoid them and find a contractor who is licensed and insured.

The same rule should apply to experience. If a contractor does not have any experience in completing projects in schools of office buildings, it is best to forego taking a risk on a small contractor. Instead hire an HVAC company that has a track record of servicing schools and offices.

Billing And Costs

A good air conditioning repair Houston company will offer you a concrete price as well as a realistic estimate on how long the project should take to complete. If a contractor is not being transparent and giving you a concrete figure on the costs, this is a sign that they may be overcharging you or will insert hidden fees and charges into a contract. Read the fine print in a contract and ask for actual numbers on the expenses. If a price is too good to believe, it probably is and you should look to another contractor.
