How Important Is It To Get The Right Size Of Heating And Cooling Equipment?

HVAC sizing is one of the trickiest things to get right when designing a new home. Going overboard has its pros and cons. Being too conservative also brings its own share of problems. The knowledge of seasoned professionals will help a lot to determine what size is just right given all of the pertinent factors surrounding the installation. A good match means that the following are all given proper attention:


The reason HVAC systems exist is to bring comfort to the inhabitants of a structure whether it is a house or a large building. The air conditioner should be able to have enough power to offset the heat brought in by the warm weather. The heater should keep people warm in the midst of winter. An underpowered system will not suffice when the peak of the seasons hit. An overly large system, on the other hand, may bring too much heat or fail to deal with humidity because they get cold too fast.


No one wants to spend more than they have to. Overestimating the size of the HVAC units will inevitably lead to higher costs than is actually necessary. Of course, trying to lower the cost should not be an excuse to grossly underestimate the requirements either as this has a negative impact as well. Professionals must estimate the perfect HVAC sizing using scientific and rigorous standards so that homeowners can find their ideal system at a reasonable price.


When it comes to maintenance, less is more. The smaller systems are easier to manage than the large ones that have complicated configurations and greater needs. There are just more things that can go wrong with bigger systems like central air conditioning compared to tiny window units.

Energy Use

Proper HVAC sizing will guarantee that the system will not draw more power than it actually needs. Heating and cooling appliances are already responsible for much of the household expenditure. Both environmental and economic concerns make it vital for people to limit their energy consumption.

Measuring Your HVAC Efficiency

Homeowners today are increasingly more aware of our carbon footprints and want to help reduce the harm we do to the environment. Many of us drive fuel efficient cars. Another way you can help the environment and yourself at the same time is by making sure that your air conditioning and heating (HVAC) system runs efficiently also.

The more efficiently an HVAC system operates, the smaller the amount of energy it uses. This not only saves energy but money as well. The U. S. Department of Energy, working with the HVAC and utility industries, sets the government efficiency ratings that help consumers determine the best systems to use for their specific needs. An inspection of your home or business by a qualified HVAC technician will help you to determine the size of HVAC system that will perform best for your needs. Such an inspection can also determine if your current system is operating as efficiently as it should.

When purchasing a new HVAC system, there are five rating systems you should know and understand.

• EER: The Energy Efficiency Ratio is based on the hottest day of the year for the cooling season. The EER lets you know how much cooling to expect for each energy dollar you spend.

• Energy Star: is an Environmental Protection Agency (EPA) designation only given to HVAC units and equipment that meets or exceeds high efficiency guidelines, such as how much it contributes to energy savings nationwide and enabling the purchase price to be recovered by the property owner through energy savings within a few years after purchase.

• HSPF: The Heating Seasonal Performance Factor is a measurement of the heat pump’s heating component’s efficiency. HSPF ratings range from 6.8 to 10. A rating of 7.5 or more is considered high-efficiency.

• MERV: The Minimum Efficiency Reporting Value rates HVAC filters’ efficiency by the size of the holes. A filter with smaller holes is more efficient at trapping contaminants. MERV ratings range from 1 to 16, which is the highest available efficiency rating.

• SEER: The Seasonal Energy Efficiency Ratio shows the cooling power you can expect from your HVAC system for every energy dollar spent based on the whole season’s average total. SEER ratings range from 13 to 22. The higher the number is, the higher the efficiency of the unit is.

When you are shopping for a new HVAC system, select yours with these efficiency ratings in mind to choose the best system for your space, based on the information your inspection provides you. If your system is running well but is ten or more years old, you might consider updating as there have been many improvements in the last decade.

Ways To Increase Your Air Conditioner’s Efficiency

The air conditioning efficiency of your AC (air conditioner) is affected by its (AC) components’ performance, as well as its environment. In order to increase the efficiency of your air conditioner (AC), you must ensure its components are in excellent condition and that its environment is free of airflow obstructions. You can also get the best from your AC by ensuring your AC’s thermostat is not overly exposed to unnecessary heat.

Ways to increase air conditioning efficiency in your home

  • Keep heating sources away from your AC and thermostat

Your AC’s thermostat’s settings are triggered by the degree of air temperature closest to it. Placing heat generating equipments such as bulbs, iron boxes, and computers close to your AC’s thermostat increase the level of heat that the thermostat picks. The more a thermostat detects a rise in the degree of indoor air temperature, the more it overworks your AC in an attempt to provide sufficient cooling, which may not be required in the areas of your home that are away from the heating source. Whenever possible, install all thermostats high-up on the wall, or on other surfaces that are not heat-biased.

  • Clean your AC’s environment

Your AC’s efficiency can only be guaranteed if there is sufficient air flow through the system. Clean your outdoors, near your AC’s vents, so that airflow is not compromised by obstructions. It is also important to ensure that the air handlers on the inside of your home are not blocked by pictures or other flames as this overworks the entire AC system. Keep the AC’s vents free from debris or large furniture that limit air flow.

  • Schedule routine check-up and maintenance of your AC

Perhaps, the most important aspect of increasing your AC’s efficiency is by ensuring that all components are in peak condition and function optimally. Schedule routine AC check-ups, by a trained HVAC technician, to detect potential damage, dirt or other issues that may limit their performance, hence the performance of the entire AC. Clean, replace, repair and or grease AC’s components accordingly.

A high air conditioning efficiency translates to increased quality of your indoor air and your utmost comfort. Since AC’s efficiency can be compromised by internal and external factors, mitigating those factors can increase its efficiency. Remove air flow obstructions, place thermostats away from heat-generating equipments and service your AC regularly. Call us for all heating and air conditioning needs.

5 Home Cooling Myths

There are 5 home cooling myths you should be aware of. Read on to find out what those myths are.

1. AC Just Cools The Air
It’s true that air conditioners do provide cool air, but they do more than that. They actually can reduce humidity in the summer. Many air conditioners have a drying function and this helps reduce humidity.

2. Fans Keep Rooms Cool
When you use a fan in a room, it doesn’t make it cooler. All it does is make you feel cooler, and this means it actually does nothing for the heat inside the room. This also means that if you’re not in the room, you’re simply wasting energy when you decide to leave the fan running.

3. A Bigger AC Means Better Results
You might be tempted to upgrade to a bigger AC because you think it means better results. However, if your AC isn’t working as good as you think it should be working, then perform some maintenance on it, and fill in any gaps that need to be filled in.

4. For Faster Cooling, Crank The Temperature Down
Turning your central AC’s temp way down doesn’t result in faster cooling. However, if you have a window AC, you can choose the highest setting, and this should result in faster cooling.

5. It’s Better To Leave It On All Day Long
You might think it’s better to just leave your AC on all day long to get the best results. A programmable thermostat are great because they can help you save cash on your energy bills, both in the winter and summer.

What Is A Fixed Chassis Air Conditioner?

Environmental temperatures tend to get extreme sometimes, which makes it a necessity to invest in quality Air Conditioning units. There are two types of ACs in the market; the fixed chassis and the slide out chassis air conditioners. The type of air conditioner one chooses will determine its application and how one interacts with it at home.

What is a Fixed Chassis?

The fixed chassis AC is also known as the window air conditioner. Its body is designed to fit in a window frame and the name ‘fixed’ refers to its body which cannot be easily opened. This is differs with the slide-out chassis AC which opens easily by sliding the body.

Installing a Fixed/Window Air Conditioner

It takes only three steps to complete installation of a fixed window AC. First, window measurements are taken then the AC is screwed down to fit and finally the outside is caulked to make sure it fits perfectly and remains stable during operation.

Location Choice

Fixed chassis air conditioners are widely preferred because they don’t require a permanent change of the area where they are fixed. For a wall or slide out chassis air conditioner to be installed, part of the wall has to be holed out; a privilege only reserved for businesorary and can be taken down easily.


Since they are temporary fixtures, window or fixed air conditioners give lots of flexibility during seasonal changes. It is easy to erect the AC during winter and take it down when winter is over. For slide out or wall air conditioner, the fixture has to remain intact regardless of the seasons.


Fixed chassis air conditioners not only fit in windows, but can be used as wall air conditioners as well. The opposite however is not possible for wall air conditioners; they have limited features which will not vent properly when used on a window.

This is the main difference between the fixed chassis and the slide out chassis air conditioners. Whichever you choose depends on area of application and the weight of advantages.

What Would Be Most Effective In Controlling Home Comfort Costs?

If you are wondering if energy prices continue to escalate, what would be most effective in controlling home comfort costs, maybe this will help you. There are a variety of things that you can do to control your home comfort costs, here are some of them.

You can add insulation and weatherproofing to your home. These things can save you money and also help you to conserve energy. With insulation, you can add it to your water pipes to decrease the energy that would be lost when it delivers hot water to your home. For weatherproofing, you can weatherproof your windows and doors. Doing this will conserve energy so that your heating system doesn’t have to overwork itself. Insulate windows with felt, vinyl, or self adhesive foam. Insulate doors with weatherstrips and metal sweeps to seal gaps on the bottom of the door.

One of the best things that you can do is get a programmable thermostat. This thermostat can decrease and increase the temperature of your home. It will decrease when you are not home and increase when you are home.

Insulate your exterior and interior of your house. If your exterior walls don’t have interior insulation, see if you can have blown in insulation professionally installed. For you interior, insulate around electrical outlets, heating and ventilation ducts, and pipes. Look for small openings where cold air may be coming in. It is best to get the holes insulated so that air doesn’t come in or escape your home.

If you have a fireplace, use it. Wood burning fireplaces though are net heat losers. If you have one of those, install a wood burning insert. This will give you the efficiency that you need when using the fireplace.

As far as summer is concerned, you should help your house keep cold. Metal and white cement roofs help keep homes cooler during summer months. Attic fans and whole house fans also can help beat the summer weather.

For additional energy savings solutions, call us today. We can help you save money for your home during the summer and winter months.

How Does An Air Conditioner Work?

Air conditioners work on the concept of phase conversion to cool air. They exploit a law of physics that when a liquid converts into gas, it absorbs heat. To facilitate phase conversion, air conditioners force special compounds into a cycle of evaporation and condensation in a closed system of coils.

The chemical compounds are refrigerants that are able to change at very low temperatures. Air conditioners also have fans that move warm interior air over the cold refrigerant coils. When hot air flows over the cold evaporator coils, heat is absorbed by the refrigerant as it changes from liquid to gaseous state.

For the air conditioner to keep cooling efficiently, the refrigerant has to be converted back to liquid again. This is made possible by the use of a compressor that puts the gas under high pressure. The process creates unwanted heat which is evacuated from the system using a second set of coils referred to as condenser coils and a second fan.

As the gas cools, it reverts back to liquid state and the process starts all over again. This cycle creates a series of phase conversion of refrigerant liquid that leads to absorption of heat and then compression and phase transition of gas back to liquid.

In addition to cooling indoor air, air conditioners also regulate the air temperature via a thermostat. Moreover, they are fitted with onboard filters that remove air borne particles from circulating air. They also function as dehumidifiers. By reducing the temperature of a volume of humid air, a portion of moisture in the air is reduced. This explains why air conditioners discharge water when operated on humid days.

In between the two sets of condenser and evaporator coils is the expansion valve. Its role is to determine how much compressed liquid refrigerant moves into the evaporator. There are some additional timers, valves and additional sensors to ensure things run smoothly but the aforementioned parts are the main components of an air conditioner.

Now that you have some air conditioning basics at your fingertips, you understand how an air conditioner works. You can always call us for all your air conditioning and heating system needs.

The Raising Of Current Efficiency Standards Is Placed On Hold

Over the years there have been many amazing developments in the HVAC industry. Many of these developments concentrate on preserving energy and natural resources. In 2009 the U.S. Department of Energy partnered with several experts in the HVAC industry to improve on HVAC Efficiency.

As a result HVAC equipment manufacturers have been developing equipment that is far more efficient. Creating the annual fuel utilization efficiency, or the AFUE, rating system helped the DOE to measure the efficiency of fuel powered furnaces and boilers. HVAC manufacturers responded by creating the condensing furnace that has an AFUE rating of 90. A condensing furnace with this high rating is estimated at being the most efficient because it only wastes ten percent of the fuel it uses to heat homes.

Most of the existing combustion types of furnaces installed in homes located in the northern states have a meager AFUE rating of just 78. In fact, the current minimum required AFUE rating is set at 78 in states like New York. After the development of the efficient condensing furnace, the DOE made a move to raise the minimum HVAC Efficiency Standards to 90 in northern states.

In 2013 the DOE was ready to enforce the new efficiency standard of 90. Experts in the HVAC industry stood up for homeowners and their fear of this new efficiency standard and have stopped the enforcement of it, for now. They fear this enforcement because thousands of homeowners will have to make expensive modifications in order to add a condensing furnace into their HVAC system when their existing furnace wears out. The condensing furnace requires a different venting system than what most existing HVAC equipment uses.

The cost of purchasing the new furnace, a new venting system, as well as paying for the modifications and installation of the new furnace will far exceed what many homeowners can afford. However, for some homeowners, installing an AFUE 90 rated furnace was no issue financially and they are already enjoying the rewards of lower heating costs. The best way to learn more about efficient furnaces and to keep up with all that is transpiring in the court system about the raised efficiency standard is to contact a local HVAC company.

Protect Your Entire Home From Power Surges

Do you know how well your electronics are protected from power surges? If not, it might be time to become concerned because a strong surge of voltage can render your home appliances useless. Inner electronic parts are sensitive and are not capable of handling high voltage surges. Most homes have Home Power Surge Protection equipment installed inside the breaker box.

There are several things that can cause a power surge in your home. Generally an external power surge is caused by lightning, accidents, and other things that interfere with power lines. Internal surges are caused by appliances, faulty wiring or issues with wires that are not grounded properly.

Internal surges are also caused by large appliances such as boilers, air conditioners, furnaces, refrigerators, and other large appliances. When these large appliances turn on they require a lot of energy. This energy is dumped back into the electric lines when the appliance turns off, and as a result the sensitive electrical components are slowly worn down and damaged. You can protect your valuable electronic appliances by installing additional surge protection.

A lot of homeowners think that their whole house surge protection is enough because most are rated to stop up to 50,000 amps. This is not enough though, quite often surges are strong enough to break through that protector and damage sensitive electronics. Lightning is usually the culprit when the whole home surge protector fails.

There are two additional devices you can install that will help prevent internal and external surges from damaging your televisions, computers, as well as costly HVAC equipment. Electricians and HVAC specialists recommend that homeowners install a surge protector electric outlet where large appliances will be plugged in. It is also recommended that a power strip is used to plug in sensitive electronics like computers and televisions.

One way to find out how to better Protect Your Home Utilities is to schedule a test on your home’s total electrical grounding system. You can have this system checked out during your regular HVAC Maintenance visit. The technician will also make sure that all of your surge protection devices are functioning properly. Contact your favorite HVAC contractor today and schedule a home grounding system test to make sure your expensive electronics are protected to the hilt.
