Humidity Control Services

One way to control the indoor air quality in your home is by controlling the humidity. Air that is too humid creates a breeding ground for mold and mildew, while air that is too dry can irritate your airways. Humidifiers and dehumidifiers help keep humidity levels stable, so you do not have to struggle with these issues.

Contact McCrea Heating & Air Conditioning for humidifier and dehumidifier services.

Ductwork Services

Air ducts are a place where problems can hide. Dust and allergens get built up inside, leading to problems with your indoor air quality. Leaks in the ductwork can also allow more contaminants inside the system, making the problem worse. We offer the following ductwork services to help:

  • Air duct cleaning – Remove the dust and grime from your air ducts to keep the air cleaner inside your home.

  • Ductwork installation – New ducts that are free from dirt and leaks can be a benefit to your home’s indoor air quality.

  • Ductwork repair – If you have some leaks or problems, let our team repair them for you.

Indoor Air Scrubbers and Air Purifiers

Even with the cleanest ducts, you will still have toxins that can circulate in your home. Air scrubbers and air purifiers add another layer of protection to prevent those from making you sick. These install directly into your HVAC system to remove allergens and contaminants so that you can breathe freely.

Refrigeration and R-22 Conversions

If you have an older HVAC system that is still using R-22 or Freon, you will have trouble. R-22 has been fazed out, and as such, you cannot get Freon to recharge your refrigerant. In addition, Freon is highly damaging to the environment, and leaks can put your home at risk. Reach out to our team to learn more about refrigeration services and R-22 conversions, so you don’t have to worry about this risk.

Contact McCrea to schedule refrigeration and R-22 conversion services.
