Carlsbad Indoor Air Quality

The air in your home may be a bigger source of concern than you realize. In fact, the air inside is often several times worse than the air outside, and in an environment like Southern California, that’s not a good thing. If you’re struggling from the effects of poor-quality indoor air, the team at John Stevenson Plumbing, Heating & Air can help. Since 1990 we have helped customers just like you take control over their indoor air quality, improving their quality of life and even helping their HVAC system run better than ever.

Contact John Stevenson Plumbing, Heating & Air at (760) 276-6690 for more information about our specialized indoor air quality solutions.

Air Balancing

Have you ever noticed that one room in your home feels extremely cold when you run your air conditioner while a room on the other side of the house might as well be just as hot as the temperature outside? This is known as an “unbalanced” HVAC system, and the team at John Stevenson Plumbing, Heating & Air can help you fix it. Our air balancing services modify your duct network to ensure air from your air conditioner and heater seamlessly and evenly travels throughout your home for uniform heating and cooling. This can even help reduce energy bills by improving air conditioner or heater performance.

Air Filtration

 Do you have a constant dust problem? Is pollen a huge problem throughout your home? These are a few of the issues that can be rectified with improved air filtration. Upgrading your HVAC system’s filtration system can significantly increase the amount of airborne particulates that are removed every time air cycles through your HVAC system. Some air filtration systems are standalone and can greatly improve quality in sensitive areas of your home while others can be installed directly in your current HVAC system for improved performance across your property.

Humidity Control

Indoor humidity is a bigger problem than most people realize. While Southern California may be known for our temperate climate and fairly dry air, too little humidity can lead to dry skin, frail hair, and plenty of other issues. A whole-home humidifier from John Stevenson Plumbing, Heating & Air fixes this issue by imbuing the air that passes through your HVAC system with humidity. For more precise and comfortable air, call us to find out more about the great options we offer in Carlsbad, Rancho Bernardo, and the surrounding areas!

Air Purification

Air purifiers go above and beyond air filtration systems to remove or neutralize even dangerous microbes and biological organisms that your filter may not be able to remove on its own. Air purifiers can target things like smoke particles, stale odors, mold spores, bacteria, viruses, VOCs, and so much more, all of which might be in your air without you even knowing.John Stevenson techs taking tools out of van

Frequently Asked Questions

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?
    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.
  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?
    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.
  • What Type of Central A/C Unit Should I Install?
    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
  • How Much Does it Cost To Get My Air Conditioning Unit Installed?

But no matter what unit you pick out for your home, ask an expert at John Stevenson Plumbing, Heating & Air for fast answers & reliable service. Trained technicians can come to your house to give you an upfront, transparent installation report, as well as consult you on what unit your home will need.
