Avoiding Carbon Monoxide Poisoning

Posted on: December 12th, 2017 by Precision Temperature No Comments

Carbon monoxide poisoning results from a build-up of carbon monoxide, a colorless, odorless gas, and can be fatal. The typical sources of excess carbon monoxide (CO) are very common during the winter, so it’s especially important to be on the lookout for symptoms of carbon monoxide poisoning and take steps to avoid it in your home. Learn about the sources of excess carbon monoxide, the symptoms of carbon monoxide poisoning, and how it can be avoided in this blog.

CO Sources

Carbon monoxide is found in the fumes created from burning fuel in cars or trucks, small engines, gas stoves, lanterns, grills, fireplaces, gas ranges, or furnaces. When trapped indoors, CO can build up and poison people and animals who breathe it.

Symptoms of Carbon Monoxide Poisoning

The symptoms of carbon monoxide poisoning are often described as “flu-like.” They frequently include dizziness, weakness, headache, chest pain, confusion, upset stomach, and vomiting. Prolonged inhalation of CO can cause you to lose consciousness or even die. People who are drunk or sleeping can die from carbon monoxide poisoning even before showing symptoms.

Everyone is at risk from carbon monoxide poisoning, but infants, the elderly, and people with heart disease, breathing problems, or anemia are more likely to be affected by CO.

Avoiding Carbon Monoxide Poisoning in Your Home

An important part of preventing carbon monoxide poisoning in your home is keeping any fuel-burning (gas, oil, or coal) equipment and appliances well-maintained. Your fuel-burning heating system and water heater should be serviced by a professional once a year – before the heavy use of the cooler winter months is a good time to do this.

You should also install a battery-operated CO detector in your home in a location where it will wake you if it sounds while you’re asleep. Check the batteries at least twice a year and replace them as needed. If the carbon monoxide detector alarm sounds, you and your family should leave your home immediately and call 911.

Other ways to prevent a potentially deadly build-up of carbon monoxide include: not using portable heaters or generators indoors; making sure fuel-burning appliances are vented properly; and checking your chimney is clear and cleaning it if necessary.

If you suspect you or a family member has carbon monoxide poisoning, seek medical attention right away.

Understanding SEER Ratings

Posted on: December 1st, 2017 by Precision Temperature No Comments

When you’re choosing a new HVAC system, one of the factors your San Diego HVAC technician will present you with is each potential unit’s SEER rating. But what does the SEER rating mean and how should it factor into your decision about what HVAC system to choose?

What is SEER?

An air conditioning unit’s efficiency is often measured by the Seasonal Energy Efficiency Ratio or SEER. The air conditioner’s SEER is calculated by dividing the unit’s cooling output during a typical cooling season divided by the total electric energy input during the same period. In the U.S., the SEER is the ratio of cooling in British thermal units (BTU) to the energy consumed in watt-hours. The higher the HVAC unit’s SEER rating, the more energy efficient it is and the more money you could potentially save on your energy bills.

Factoring SEER into Your Purchase Decision

Since January 1, 2015, the U.S. Department of Energy has required that all new air conditioning systems installed in California must be a minimum of 14 SEER or higher, so you can’t choose one below that threshold. However, choosing the HVAC system with the absolute highest SEER rating may not be the correct decision either, even though a higher SEER rating can mean more efficiency. Your purchase decision must also be based on the square footage of the area you are trying to heat or cool. A unit that is too big for an area will not yield any efficiencies but will actually overcompensate, while a unit that is too small will have to work overtime, driving up utility bills and putting strain on the HVAC equipment that will cause it to wear out faster.

You’ll also need to consider other factors that influence the temperature in your home or business and how they can impact energy efficiency in order to fully realize the potential savings of your new HVAC system. Make sure your building is properly insulated and sealed against air leakage and radiant energy; you can check out our blog for tips on weatherization.

Your local San Diego HVAC professional can help you decide what size heating and air conditioning unit your home needs, recommending the SEER rating that will help you achieve maximum savings both short- and long-term.

3 Winter Home Heating Tips

Posted on: October 4th, 2017 by Precision Temperature No Comments

Though far from frigid, winters in the San Diego area can get downright chilly, especially away from the coast! Here are three tips to help keep your home warm this winter without sending your energy bills through the roof.

  1. Take Advantage of the Power of the Sun

One way to warm up your home without turning up the heat is by opening your blinds and allowing the sunlight to warm the room’s air. Once direct sunlight is no longer hitting the window, closing the curtains or blinds can help prevent any heat gained from being lost again.

  1. Check Your Home’s Insulation

Insulation limits the transfer of heat into or out of your home, reducing the amount of energy required to maintain your desired interior temperature. If your heating costs are rising, your home may not be properly insulated, allowing the heat from your carefully warmed home to transfer away into the cold outdoor air.

  1. Reduce Air Leakage

Preventing indoor air from leaking out of and outdoor air from leaking into your home helps maintain a constant interior temperature. Caulking cracks and around doors and windows and weatherstripping doors helps reduce air leakage.

Fall is the best time to prepare your home and heating system for the winter. Clean or replace your air filter and test your system now to ensure it works when you need it.

If your heating costs are rising, you might need a more efficient heating, ventilation, and air conditioning (HVAC) system. Precision Temperature can help you find the best system for your home and wallet. We can also help keep your system running at peak efficiency with regular maintenance service.

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.
