Things to Consider for Chilled Water System

For any commercial company, regardless of size, overhead costs and safety are of the highest concern to be handled efficiently.  Chilled water systems come to mind here because your ac system is a must for comfort, productivity, and safety.  The pros and cons for a chilled water system will be discussed below, but what’s to be remembered is that overall, chilled water systems are cost effective avenues for cool temperatures that are also safe. Safe because having refrigerant piped all over your commercial building, has inherit hazards, and chilled water systems take that hazard out.

 

Advantages

·         Energy Reduction and Lower Utility Bills – Compared to standard air cooled chiller/HVAC system

·         Noise Reduction – Extremely quiet choice, excellent in certain environments.  Water is not as susceptible to duct and vent expansion and contraction.

·         Healthier Option – water is non toxic and non corrosive, unlike your standard cooling systems that use refrigerant and other chemicals for operation

·         Safer Solution – again, no refrigerant piped hazard to be worried about

·         Longevity – Lasts longer than standard air cooled chiller alternative because water chilled is installed indoors and the alternative is outdoors, impacted by the elements.  Also alternative uses chemicals that the water chilled system doesn’t require

 

Disadvantages

·         Higher Upfront Costs – All technology advanced equipment costs more upfront than the standard option. Also, more complex units tend to have higher labor costs due to specialized training.  It can pay for itself over time in a multitude of ways (think advantages)

·         Standard Maintenance Increase – More working parts means more chance of increased inspection, repair, and/or replacement of faulty parts. Water treatments will also be required.

·         Not as Effective in Humid Environments - Higher levels of humidity raise the wet-bulb temperature, which is an indicator of how efficiently water absorbs heat. This equates to higher operating costs.

Whether you are ready for your first water chilled system or need a repair or replacement to your already installed unit, the HVAC technicians at Expert Air are certified, knowledgeable, and professional.  For all your commercial needs, you can rely on Expert Air.

Should You Go with Zone System for Your HVAC

If you are tired of having an imbalance in temperatures in your home or office building, you may be suffering from inadequate cooling options, with a solution option of zoning for your HVAC system. If during the summer months, it seems some rooms never cool off, or in the winter it seems some rooms never warm up while others do, you may need to consider zone systems for your residential or commercial cooling needs.

To determine if you should seriously consider changing your current ac system and retrofit a zone system or to have a new installation all together, consider the following:

1.       Some areas get hotter or colder than others

2.       Do you have multiple floors in your floor plan

3.       Do you have vaulted ceilings

4.       Do any of your rooms have floor to ceiling windows

5.       Do some rooms get little to no use

6.       Does a part of your structure lay over a basement

7.       Do certain users have different temperature needs than the rest

If you answered yes to two or more of the above questions, you should consider contacting Expert Air, your local HVAC contractor, to determine if a zone system is advised for your home or office. Ideally, you can expect to spend around $2,500 - $3,500 if the zone system is installed at the beginning, whereas if you are installing only part of the overall HVAC system, you can anticipate higher costs.  To get an accurate estimate, contact Expert Air for your onsite evaluation.

 

 The main factors to evaluate when considering zoning for your HVAC system include:

 

·         Comfort

o   Improved comfort is the main goal for HVAC zone system

o   Eliminate hot or cold spots, regardless of ac system running

o   For those who prefer it cold, get it, while those who like it a little warmer, get it too

·         Save Money

o   Conserve energy and lower your monthly utility bill

o   Specifying the area for cooling/warming instead of a whole home/building means no wasted energy

·         Control

o   The ability to choose individual sections for specific temperatures. Takes comfort, energy savings, and overall control into consideration

Whether you are focusing on one, two, or all three factors for benefits of HVAC zoning, the professionals at Expert Air are trained and efficient in evaluation, installation, or repair.  Let the knowledge of all the pros and cons of zone systems be at your fingertips, when you work with the HVAC certified technicians at Expert Air.

Why Duct Sealing is Important

 

Duct sealing becomes necessary when leaks are present. Leaks can occur over time. If you’ve noticed higher electricity bills, more humidity in the ac system, or decreased air quality, it’s time to call the professionals at Expert Air. Duct sealing is necessary but beyond the requirement there are multiple benefits to the HVAC service provided by Expert Air. Below are the major benefits of duct sealing, whether residential or commercial.

·         Increased Comfort.

o   Consistent temperatures, experience what you want when you want. Reliability.

·         Indoor Air Quality Improvement.

o   Decreased pollutants caught in the ductwork that triggers allergy or asthma symptoms.

·         Elevate Safety Measures.

o   Backdraft occurs when leaky ductwork is what you have. Functioning appliances naturally release combustion gases through the ventilation system. Duct sealing increases safety in your home or business.

·         Lowered Expenses.

o   Upfront costs pay themselves off sooner than expected when it comes to duct sealing

o   Save up to 30% in energy bills

o   Lowered energy consumption equates to lower energy bills and an ac system that works more efficiently

If you are ready to experience all the benefits of Duct sealing and enhance the lifespan of your HVAC system, contact us at Expert Air to schedule your appointment, discuss in-house financing, or to schedule your free estimate.

DIY HVAC is Not Advised, Leave it to the Professionals

 

Spending money happens as automatically as breathing or blinking.  Almost everything we do today, from work to play and everything we need to get things done like cars, food, and air conditioning all cost money to maintain.  When the opportunity presents itself to save money by alternative methods, sometimes what saves money today costs more money tomorrow.  DIY projects come with a lot of inherit risk, so we discuss why hiring professional and certified HVAC technicians is the advisable route.  Expert Air HVAC technicians Houston will save you time, patience, and money from the start.

Reason #1: SYSTEM IS COMPLEX

Certification and training are required for HVAC systems and home ac units due to the level of complexity and difficulty in handling.  Don’t be fooled by YouTube tutorials, this is one unit that is not an easy feat. One malfunction can lead to total system failure, for all components work together, so you need to be knowledgeable of the entire system and on an individual part level. The gamble in handling HVAC systems when not certified or truly knowledgeable is unsafe with highly dangerous results, and that far outweighs the cost savings. Those cost savings will wither away in repair, let alone if something more dangerous were to occur, like a gas leak or a fire!

Reason #2: REPAIR REQUIRES SPECIFIC TOOLS

One size doesn’t fit all when it comes to AC and HVAC systems.  Every model varies, and the route to repair is not paved the same.  Having the right tool matters, and you should know that the professional tools accessible to Expert Air HVAC technicians and certified AC technicians are not what you will find in your local tool shop.

Reason #3: WHAT’S MORE VALUABLE, YOUR TIME OR YOUR MONEY

When you are outside your depth completely or whether you are rusty by a decade or so, the learning curve for DIY projects in AC repair is highly time intensive. Trial and error is not something you want to chance when it comes to ac units.  The multitude of hours you will spend researching and hopefully learning prior to risking hands-on efforts, the professionals at Expert Air can have done in no time at all.  Remember all the time you are researching; your air conditioner isn’t working.  In Texas heat, those minutes and hours are precious for overall comfort, hours of heat take even more time to cool back down, so you are doubling the time of discomfort; which only adds to your frustration.  Add to everything, you have a higher chance of malfunction and a costlier repair if you attempt to repair your home ac unit yourself. 

BUT WHAT CAN I DO MYSELF

Some smaller care for your air conditioning unit can be done by the owner, and below we list what those are, but remember, overall maintenance needs to be left to the professionals.  You wouldn’t want to tear your car apart and rebuild it on a whim, you would get educated on all the intricate details and have hands-on training; well your HVAC system maintenance should be considered in the same concept, don’t try to maintain your unit alone, rest easy knowing Expert Air technicians are certified and experienced, let our expertise keep you comfortable.

For the usual homeowner who doesn’t possess the skill set to safely and properly repair their home ac unit, what they can do themselves include the following DIY efforts:

1.       Change the Air Filter, monthly replacement is standard, but if you have a full house and animals, you may need to do this more frequently.

2.       Don’t Block the Vents, ensure curtains and furniture don’t block your vents, for they can stop cool air from reaching your rooms.

3.       Clear Exterior Unit of Debris, trash, branches, leaves all impact the effectiveness and potentially clog the unit causing functionality issues.

4.       Trim Nearby Plants, this helps lessen likelihood of debris; keep everything clear by 18-24 inches.

5.       Hose the Unit, with your regular garden hose, lightly spray the exterior of the unit to easily remove dirt and debris accumulation.

Perks of Relying on Expert Air:

1.       Lower Utility Bills

2.       Higher Efficiency

3.       Extended Life of HVAC System

4.       Early Problem Detection

5.       Fewer Emergency Scenarios

6.       More Bang for Your Buck

Remember, never try to do a repair that is outside your skill set, especially when it comes to ac repair Houston, for you can cause more extreme damage, cause yourself injury, and/or increase the risk for a fire or gas leak. Contact Expert Air today to schedule your estimate.
