Air Filters and Your Home

Tuesday, January 27th, 2015

John’s Refrigeration is changing the way you think about HVAC and your home. The system to heat and cool your home is really not about the unit outside – or as we like to call it, the box. The system includes the ductwork and air filter, which, when not properly sized and sealed, can cause dust, pollen, and other contaminants to enter your home, making the unit less efficient and you less comfortable.

How do air filters work?

The air that flows through your home goes through a filter before it enters the HVAC system, making it important to have the right size and kind of air filter. When the filter is clogged, the air in your home filters through those contaminants as well, blowing the dust and dirt back into your home.

 

A filter is important, not just to protect you from contaminants in the home, but to also protect your air conditioning and heating unit from damage. The Environmental Protection Agency (EPA) reports changing your home’s air filter as the most important part of maintaining your home and making the HVAC system efficient.

Sizing Air Filters and Ductwork

Filters that aren’t sized properly, including the newest on the market, can actually make your system less efficient by blocking airflow. This causes the entire system to work harder and use more energy. That translates into a higher utility bill for you.

The same holds true when ductwork isn’t sized and sealed properly. Your home breathes just like you do. When it’s not operating efficiently, it’s like it’s having an asthma attack; working harder for the same output.

The role of filtration is to protect the coil, not filter air around the house. In some cases, the solution for an asthmatic system is to use a basic (cheap) blue air filter that keeps the airflow at an efficient rate. Other solutions include having the ductwork evaluated to make sure it is sized and sealed properly so that dust and other contaminants are not entering the home.

Our team wants your home to be energy efficient and for you to feel comfortable. If you’re concerned about the efficiency of your home or aren’t as comfortable as you’d like it to be, Just Call John’s.

3 Tips to Fix Pressure Balance Problems in Heating and Cooling

Tuesday, January 13th, 2015

Did you know…the air in your home can be a negative, positive, or neutral pressure? It’s true and it’s one of the least understood – and most important – issues in heating and cooling. Ideally you want a neutral system, but finding the balance of negative and positive pressure can be challenging and can create different zones of heat and cold throughout your home.

 

Whether it’s positive or negative, too much pressure is not good for your home. Neutral air is the most energy efficient because it means there is no air escaping through cracks or unsealed ductwork and outside air isn’t entering the home. The best pressure in your home is neutral to slightly positive as it is also the most comfortable while preventing dust, pollen, and other contaminants from entering the home.

What’s negative pressure?

When too much air is drawn into your home, it creates a condition known as negative pressure. Dust, pollen, and environmental contaminants enter your home and can cause allergies, asthma, and health risks associated with dust, mold, and carbon monoxide. Some of these issues can be resolved by properly sizing and sealing ductwork, and installing weather stripping on doors and windows.

What’s positive pressure?

When conditioned air within your home is escaping through windows, doors, and cracks into the attic and elsewhere, positive pressure is created in your home. The system just heated or cooled the air and that conditioned air is flowing right out the door – literally. It costs you in increased utility bills.

An energy audit will determine if your home has a positive or negative air pressure, as well as the cause(s), and solution(s) to get your home to neutral pressure.

Just Call John’s to schedule an energy audit and learn about the pressure in your home today.

 

3 Tips to Size and Seal Your Duct System Properly

Thursday, October 23rd, 2014

While the actual HVAC unit is important to keeping your home comfortable during the hottest and coldest months of the year, the duct system plays a key role in keeping you comfortable and healthy. If it isn’t sized properly, it can cause dust and contaminants to enter your home, hot air to be brought into your home through the A/C system, and increased energy bills.

Do you need to size and seal your duct system properly?

Your home may have ducts that are not properly installed if you experience:

  • Extremely high energy bills during the hottest or coldest months.
  • Rooms that are stuffy or difficult to keep cool or warm.
  • Excessive dust and unpleasant odors.

Test the System. The team at John’s Refrigeration can evaluate and renovate the duct system of your home, solving these problems:

  1. Size Matters. Your home breathes just as we breathe. When the ducts are too small for the HVAC system that is installed, it causes the air to be constricted and the system to work harder to heat and cool your home. We will examine every part of the duct system for leaks, blockages, and poor design.

TIP: Use the proper size air filter for your system and change the filter as directed; typically once a month. Improperly sized or dirty filters constrict the flow of air as much as an improperly sized duct system.

  1. Air Quality Matters. The key to healthy indoor air quality is having a certain amount of fresh air in the home. We can test indoor air quality and fix issues you may have, including helping fresh air flow properly through the system and into individual rooms.
  2. Hole-y Matters. In the typical home, about 20% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. Leaks cause the system to work inefficiently, costing you in utility bills. We can repair the leaks and fix breaks and get your money back in your pocket.

The team at John’s Refrigeration can size and seal your duct system properly, keeping air flowing, contaminants and dust outside the home, and you comfortable. Schedule an appointment today!

Reasons to Renovate a Duct System: Heating and Air Conditioning Repair

Friday, August 9th, 2013

The efficiency of the HVAC system of your home is dependent on many factors including the duct system. A properly sized and sealed duct system eliminates dust and contaminants as well as hot air from being brought into your home through the air conditioning system. Air conditioning repair isn’t just about the A/C unit. The team at John’s Refrigeration can help you cut as much as 20% from your heating and cooling related energy costs by testing and repairing the duct system of your home.

Did you know?

  • As little as 70% of the work the HVAC unit does actually ends up in your home. This is due in large part to the duct system being inefficient.
  • As much as 20% of the air that moves through the duct system is lost due to leaks or improper installation.
  • Our high quality and experienced home comfort specialists are authorized by SRP and APS for duct testing and repair.
  • You may be eligible for SRP and APS rebates for duct testing and repair services.

 

 

Your home may have ducts that are not properly installed if you experience:

  • Extremely high energy bills during the hottest or coldest months
  • Rooms that are stuffy or difficult to keep cool or warm
  • Excessive dust and unpleasant odors

What creates the inefficiency? The duct system is basically like the veins in your body. It carries the air from inside, through the HVAC system and back into your home. If the ducts are not sized properly, or the wrong filter is used, it creates high pressure in the HVAC system similar to high blood pressure in your body when your veins aren’t functioning properly. This makes the HVAC system work harder costing you more money.

Renovating the duct system helps the system run efficiently costing you less money.

Typically HVAC units are placed in the attic of the home. The system pulls air from the house, through the system and back into the home. In the summer the air pushed back into the home is cool and in the winter is warm. An efficient HVAC system will take all the air from the home and return the equal amount of air back into the home and will maintain a season-appropriate temperature

A proper duct system is sized, sealed and insulated properly. Having the duct system sized wrong can create high blood pressure in the system. Many times the duct system is sized wrong but it still working because of leaks. This is why we pay attention to both the sizing and the sealing of the system.

At John’s Refrigeration we want to create a healthy and efficient home environment for you and your family. Contact us today to learn more about testing and repairing the duct system of your home and applying for rebates from APS or SRP.

Tips for the Right Thermostat for Heating and Cooling Your Home

Friday, August 2nd, 2013

If you’re a do it yourself homeowner, you may have bought and installed your own thermostat for heating and cooling. Did you know? Thermostats you purchase at the big box stores are not the same quality and grade we use for our customers.

As an HVAC contractor we are able to purchase contractor grade thermostats that generally have a five year warranty and are higher quality. This isn’t to say the box store thermostat you bought isn’t good for your home. There are plenty of great options.

 

Here are tips for selection and installation of the right thermostat for your home:

  1. Type of HVAC System: The type of thermostat depends on the type of system you have at your home. The most common are heat pump or gas heat. Some thermostats are universal so it important to check the box before purchasing.
  2. Programmable: Most people choose a programmable thermostat to help manage energy costs. Cool the home when rates are off-peak to save money. There are now thermostats that can be accessed through an app. You can turn the fan on and off and manage the temperature of your home right from your cell phone!
  3. Installation: This may surprise you – We recommend* not looking at the installation instructions for wiring. Simply take a picture of the old thermostat and install the new one the same way. Remember to turn off the air handler before beginning uninstall and re-install.

*If the new thermostat has a C terminal and the old one did not, you need to call us for assistance. Please turn off the breaker to the air handler. If the unit is on the roof, please turn off the entire unit before starting any installation and especially of the old thermostat had a C terminal.

At John’s Refrigeration we want you to feel comfortable breathing clean air in your home. Should you have questions about your HVAC unit or the thermostat installation, please do not hesitate to give us a call!

Quality Home Comfort Award to John’s Refrigeration

Tuesday, June 4th, 2013

 

John’s Refrigeration of Mesa AZ was recently named one of Contracting Business.com magazine’s 2013 Quality Home Comfort Award winners.

Their project is a system renovation and retrofit in the 4,000 sq. ft. home of Bill and Aimee Edwards of Scottsdale, AZ. The Edwards suffered from a lack of comfort in their home and were looking for someone who could provide a cost-effective solution. By listening to their customer and doing a thorough investigation of their home and mechanical system, the team at John’s was able to discover that the homeowners had uneven temperatures throughout their house, high utility bills, and a significant dust problem. They also discovered that the Edwards’ home suffered from major duct leakage, not enough return air, and a lot of duct routing problems.

By paying attention to the details, working to correct the problems in a cost-effective manner, and then testing their work and properly commissioning the system, Johns’ Refrigeration was able to solve the issues and create a much more comfortable and healthy indoor environment for the Edwards family.

The Quality Home Comfort Awards is a program the Contracting Business.com magazine launched in 1991 to recognize quality in professional residential HVAC contracting. Since that time, more than 100 outstanding HVAC projects have been recognized. Winning projects, like the John’s Refrigeration effort, will be featured in the July, 2013 edition of ContractingBusiness.com magazine and posted online.
