Fresno, CA, Indoor Air Quality Services by Donald P. Dick Air Conditioning

Many people tend to think temperature is the most important part of indoor comfort. While temperature plays a big role in your indoor comfort, indoor air quality is just as important. When you are breathing in too much dust, when you can smell lingering odors or when you have concerns about ventilation, your indoor comfort may be compromised. Using an air quality system, such as an air purifier, a dehumidifier or an energy recovery ventilator, can significantly increase the quality of your indoor air. But to gain the benefits any of these products have to offer, it’s important to hire a trained expert for installation, repair and maintenance. These types of products work seamlessly with your existing HVAC system, and if poorly or incorrectly installed, they won’t just do a poor job of improving your air, they may negatively impact the operation of your system. The whole purpose of installing an air quality system is to improve your home’s indoor air, so call the people you can trust to properly install your new indoor air quality product: Donald P. Dick Air Conditioning.

Why Install an Air Quality System?

It’s no secret that today’s indoor air can be far more contaminated than the outdoor air. One of the main causes for this the increased air–tightness of homes and using HVAC systems that circulate the same air throughout your home. Many HVAC systems come with an air filter, but these air filters are not meant to improve your home’s indoor air quality; instead, these air filters are used to stop dirt, dust and debris from building–up in your system.

The Importance of Good Indoor Air Quality

While having an air–tight home is great for energy efficiency, it’s not so great for healthy ventilation. Healthy, clean air is important in any home, but achieving this can be a challenge – unless you call a Donald P. Dick Air Conditioning expert for help. Our indoor air quality experts have a thorough understanding of what each product can offer your home, and we can install, repair and maintain your air quality system to make sure it performs as needed. Wondering if your home needs to improve its indoor air?

Air Filtration Systems

It may surprise you to know this, but the mechanical filter that comes with your HVAC system is not there to help improve your home’s indoor air quality; it is there to help reduce the amount of dust, dirt and debris that enters your HVAC system. If you are interested in the installation of a more powerful, effective air filter, make an appointment with one of our experts today.

Air Purifier

One of the reasons contaminants like mold spores, pollen and dander can get into just about anything is their size: they are very small particles. Unfortunately, the standard air filter that your HVAC system comes equipped with isn’t capable of capturing most of these small types of particles – but an air purifier can. There are a number of air purifier products available for homeowners, and working with one of the Donald P. Dick Air Conditioning indoor air quality experts can help you determine which air purifier will work best for you and your family.


Just because we have an arid climate doesn’t mean you can’t have a problem with moisture in your home. Classic signs of excess moisture in your home are condensation on the inside of your windows and clammy surfaces. The problem with excess moisture is that it promotes the growth of things like mold and mildew, and it makes dust mites very happy. Having the specialists at Donald P. Dick Air Conditioning install a whole–home humidifier can remove this excess moisture and significantly reduce or even eliminate these growth issues.

Duct Sealing

It’s estimated that faulty ductwork can account for up to 30% of a home’s entire air loss; a great way to drastically reduce the problems created by air loss is to schedule professional duct sealing. Professional duct sealing stops significant air loss and also helps improve indoor air quality. Don’t let faulty ductwork rob you of needed heating and cooling – call one of our experts today!

Duct Testing

Do you have concerns about the performance of your ductwork? One of the best ways to assess how your ductwork is performing is to schedule professional duct testing. When you hire a Donald P. Dick Air Conditioning expert to test your ducts, you can rest assured that any existing or developing problems will be found and you’ll be given a list of recommendations on how to remedy them.

Energy Recovery Ventilators

Most people don’t stop to think about the energy in their indoor air, but it’s there, and when channeled correctly, as with an energy recovery ventilator, this energy can help your home in a big way. Energy recovery ventilators, also known as ERVs, take your stale, indoor air and apply its thermal energy to incoming fresh air. This process can happen during the winter or summer months, and it helps increase your HVAC’s energy efficiency while simultaneously bringing a consistent stream of fresh air into your home.


Do you have enough moisture in your home’s indoor air? One great way to tell is if your home is set at a cool temperature, but still feels warm; this is because humidity holds heat, and when there isn’t enough humidity in your home, you can have trouble maintaining a comfortable temperature inside your home. Recommendations for indoor moisture are typically between 30%–60%, so if your indoor humidity is falling short of this, it may be time to consider the installation of a humidifier for your home.


Most people tend to think of insulation as a cold–weather product, but the truth is that insulation is necessary for year–round comfort and energy efficiency. Insulation slows the transfer of heat no matter what the season, so if you have concerns about your home’s insulation levels, call an Donald P. Dick Air Conditioning expert today.

UV Air Purifier

A whole house ultraviolet air purifier makes for a great addition to any home. It targets biological contaminants such as mold, mildew and bacteria. We install and service quality UV air purifiers throughout the area.
