When you’re in a hot weather, you may want to consider replacing your air conditioner, according to a new study.

    The research found that the number of heat-related deaths in the United States has gone up since 2003.

    And that has made it difficult for many homeowners to install a new air conditioners in their homes, the study found.

    Researchers at Duke University analyzed data from the National Heat Index and found that during the period from 2006 to 2014, the average number of deaths related to air conditioning in the U.S. increased from 2.1 per 100,000 to 3.9 per 100-person population.

    But the number actually decreased from 2003 to 2012, said study co-author Jonathan Biermann, a professor of urban planning and planning at Duke.

    So what’s going on?

    The researchers noted that a number of factors are contributing to the increase.

    The most prominent factor is the introduction of the air conditioning ventilator, a new device that is intended to help cool homes and reduce the risk of heat stroke and heat stroke death.

    According to Bierman, a ventilators have become so popular that they are often referred to as “air conditioners of choice.”

    But they also have their share of drawbacks, he said.

    First, there’s the potential for the air conditionor to become contaminated with chemicals.

    Secondly, ventilors can’t be easily removed or replaced, so homeowners have to keep an eye on their devices and make sure they are properly cleaned, the authors said.

    “They are going to become increasingly less attractive as they become more popular,” Bierfield said.

    He also said that older ventilating systems may be more expensive to replace, since they typically require more maintenance and the devices have higher energy costs.

    Bierfield and his co-authors also noted that air conditioning ventilation systems were not designed to be replaced, which means homeowners who are struggling to keep up with repairs may want a new one.

    And that means replacing an air conditionator may be a more expensive option than buying a new home.

    The average cost of a new, air conditionable home was $200,000 in 2014, according the National Association of Realtors.

    The study also looked at a number other aspects of air conditioning including ventilatory control, how often it is used and whether it’s a common appliance.

    But the researchers found no evidence that older air conditionors are more dangerous than newer models.

    “The findings from this study do not show a strong association between older and newer models,” Biersmann said.

    The researchers said that more research is needed to determine whether older models of air condition-related air safety issues have increased since the introduction in 2003.

    They also noted there are many other variables that can affect the risk and severity of air conditions, including the number and type of people who live in the home and the number that live in proximity to the home.
