Protect Yourself and Your Teens with Locking Refrigerant Caps

Posted on: August 2nd, 2017 by Precision Temperature No Comments

Incidents of teens huffing HVAC refrigerant in order to get high are on the rise. This can cause health problems such as difficulty breathing, irregular heart rhythms, nerve and brain damage, and even death. If your air conditioning unit isn’t effectively cooling your home during the hot summer months and your HVAC technician discovers that your system’s refrigerant is low, but finds no leak in your equipment, it is possible that someone is tampering with your system to huff the refrigerant.

To prevent these incidents, the California Mechanical Code was changed, resulting in CMC 1106.3.1. CMC 1106.3.1 mandates that all outdoor refrigerant service ports be fitted with locking-type tamper-resistant caps or be otherwise protected from unauthorized access. Locking refrigerant caps and the tools to remove them are not sold to the public; only an HVAC professional can install and remove them, ensuring that the refrigerant in your system isn’t accessible to your teens or those who would harm themselves by huffing it and that your HVAC system will continue to function effectively.

Be proactive about ensuring the health and safety of yourself and those around you. If your outdoor HVAC unit’s refrigeration ports are not currently fitted with these locking, tamper-resistant caps, contact a local air conditioning professional such as Precision Temperature today.

3 Ways to Improve Indoor Air Quality

Posted on: May 5th, 2017 by Precision Temperature No Comments

People are spending more time than ever indoors. The quality of the indoor air you breathe is therefore extremely important to your health. Poor air quality can contribute to health problems including asthma and other respiratory diseases, heart disease, and even some cancers. Just short-term exposure can lead to immediate effects such as eye, nose, and throat irritation, dizziness, headaches, and fatigue.

But what causes indoor air pollution, and how can you reduce it in your home or office? Below we discuss some common sources of indoor air pollution and three ways you can improve indoor air quality.

Sources of Indoor Air Pollution

Indoor air pollution can come from a multitude of sources. These can include: outdoor air pollution that is brought indoors; radon; household cleaning and maintenance products; fuel-burning appliances; building materials; home furnishings; personal care products; moisture; tobacco products; and central heating and cooling systems.

Which of these indoor air pollution sources are most and least important to your health depend on how much pollution each source contributes and how harmful each pollutant is, as well as the frequency of pollutant emission.

Improving Indoor Air Quality

There are three main strategies to help improve indoor air quality:

  1. Source Control

Preventing indoor air pollution in the first place or reducing the levels of pollutant emissions is often the most effective, cheapest way to improve indoor air quality. This can be done by eliminating the pollutant source, such as tobacco products; physically enclosing the source, such as those containing asbestos; or maintaining and adjusting the source to reduce emissions, such as in the case of gas stoves.

  1. Ventilation

Pollutants can accumulate to unsafe levels if too little fresh air enters indoors from outside. While reducing the amount of air that leaks into and out of your home can help lower heating and cooling costs, a controlled means of ventilation is then needed to prevent high levels of indoor air pollution.

Most heating and cooling systems do not bring fresh air into the building. Natural ventilation via opening doors or windows or mechanical ventilation involving fans and outdoor air intakes helps remove indoor airborne pollutants, improving indoor air quality.

  1. Air Scrubbers

Air scrubbers are mechanical systems that remove particles from the air. They may use physical filters or UV lights, or even a combination of the two. How effective an air scrubber is at removing indoor air pollutants depends on how efficiently it removes pollutants from the air, how much air it draws in, and the strength of the pollutant source. While not all indoor air pollutants can be combated using an air scrubber, air scrubbers can help improve indoor air quality.

Without proper attention to indoor air quality, the air you likely spend much of your day breathing in might be creating serious health problems. Take action by controlling the source of indoor pollutants, increasing ventilation, and investing in an air scrubber.

How To Change Your Furnace Filter

Posted on: January 31st, 2017 by Precision Temperature No Comments

Forced air furnaces require a filter to function properly and prevent pollutants from entering your home. This furnace filter needs to be checked every few months and changed when it is dirty; more frequently during the winter months when your furnace sees heavier usage. Here we provide a simple step-by-step guide to changing your furnace filter.

Step One

The first thing you should do before performing any sort of furnace maintenance is to turn off and unplug your furnace. Then you need to determine what type of filter you have. Your existing filter will be located inside the furnace or the air return vent and will have arrows on it showing airflow direction, which you will want to remember. It may help to write this down. The filter size will also be printed on the cardboard filter frame. If your filter has a plastic frame instead of cardboard, it’s reusable! You just need to clean it periodically with water and a vacuum, rather than replacing it.

Step Two

If you do need a replaceable filter, the next step is to get the right replacement. You’ll want to make sure to get the same size filter so it will fit your furnace correctly and allow it to function efficiently. Most hardware stores and home centers, as well as many online stores, sell replacement disposable filters. Your HVAC professional can recommend a correctly-sized filter that is effective at removing contaminants from your home’s air. For even more efficient removal of harmful air-borne particles, consider an air scrubber such as the Trane CleanEffects Air Cleaner, which removes up to 99.98% of pollutants and allergens from the air.

Step Three

Once you’ve located the correct replacement filter, all that’s left to do is install it. There will be markings on the filter that tell you which side should face the furnace. Slide your new furnace filter into place, keeping in mind the proper air flow direction, and replace any covers. You’re all set until it’s time to check it and change it again!

Changing your furnace filter is usually something that you can do yourself. For most other aspects of furnace maintenance, you’ll want to contact an HVAC professional. Consider a maintenance agreement from Precision Temperature. With seasonal checkups and maintenance on schedule, you’ll get peace of mind and catch any potential problems early, before they become extremely expensive to repair. Call us today at 619.588.5321

How to Weatherize Your Home and Save on Heating Costs This Winter

Posted on: December 15th, 2016 by Precision Temperature No Comments

Are you wasting money heating your home without properly weatherizing it? Weatherization helps you save money by helping you save energy on both heating and cooling, making it good for both your wallet and the environment! Home weatherization includes air sealing, improving ventilation, and adding insulation.

Precision Temperature Weatherize Home for Keeping Heat In

Air Sealing

Preventing outside air from leaking into and indoor air from leaking out of your home is an important, cost-effective way of lowering heating and cooling costs. After all, you don’t want the nice warm air you just spent precious dollars and cents to heat to the perfectly cozy temperature to leak out into the cold night air! And you especially don’t want that heated air to be replaced by cold outdoor air leaking into your home. Air sealing your home by caulking cracks and around door and window frames and weatherstripping doors can help reduce air leakage.

Ventilation

Of course, sealing all the air inside your home may not be the healthiest thing to do. Ventilation prevents pollutants and toxic contaminants from being sealed inside your home and helps maintain indoor air quality. Natural ventilation, spot ventilation, and whole-house ventilation are the main strategies you can use to achieve this.

Natural ventilation is usually the least useful strategy, due to its unpredictable and uncontrollable nature. A properly air sealed home will not be able to achieve sufficient air quality relying on natural ventilation alone because the usual cracks and holes it depends on will have been sealed to prevent the unpredictable and uncontrollable temperature changes that result from natural ventilation.

Spot ventilation helps make other forms of home ventilation more effective by removing air pollution and moisture at the source. Think of kitchen range hoods and bathroom exhaust fans. Spot ventilation is recommended for proper home ventilation and good air quality, but will not suffice as the only means of ventilating your home.

The most robust form of ventilation is whole-house ventilation. Whole-house ventilation systems use fans and duct systems to remove stale air from and bring fresh air into your home. This provides controlled ventilation throughout the house, with no unpredictable cold or hot air entering your home and raising your heating or cooling costs. Some whole-house ventilation systems can even help further reduce heating and cooling costs through changing the temperature of the air coming into the house by transferring heat to or from the air leaving the house.

Insulation

Properly insulating your home reduces heating and cooling costs and increases home comfort by reducing heat flow. Left unimpeded, heat flows from warmer areas to cooler areas. Insulation helps limit the transferring of heat into or out of your home, thus reducing the amount of energy required to maintain your desired interior temperature. A professional contractor can help you determine what type of insulation you need and where you need it, as well as help install it.

If your heating and cooling energy costs are still sky-rocketing after weatherizing your home, you may need a more efficient heating, ventilation, and air conditioning (HVAC) system.
