Frequently Asked Questions

If you’re unsure when to replace your home’s air filter, watch out for these telltale signs indicating it’s time for a replacement. These indicators shed light on the crucial role air filters play in enhancing your home’s comfort and how a small investment of time and money can yield significant improvements:

  1. Visible Dust Around Vents: It’s time to replace your filters when you can see visible dust accumulating on and around vents.
  2. Dirty or Clogged Filter: A visibly dirty or clogged filter should be replaced promptly.
  3. Extended Heating/Cooling Cycles: Longer HVAC cycles signal reduced airflow due to a clogged filter.
  4. Higher Energy Bills: Increased energy consumption may result from a clogged filter.
  5. Declining Indoor Air Quality: Worsening air quality suggests an overdue filter replacement.
  6. Hot A/C Unit: Excessive heat from the A/C unit indicates restricted airflow, often due to a dirty filter.
  7. Uncertain Last Replacement: If you’re unsure when the filter was last changed, it’s likely overdue and time to be replaced.

The time it takes to install a new A/C system in your home can vary depending on several factors, including the complexity of the installation, the size of the unit, and whether other HVAC components are being replaced simultaneously. Here’s what you can typically expect:

  1. Replacement Only: If you’re solely replacing the air conditioning unit, the installation process typically takes between 4 to 8 hours on average. Our experienced technicians at Mainstream are trained to work efficiently while ensuring the highest quality installation standards.
  2. Replacement of Furnace and A/C: If you’re upgrading both your furnace and air conditioning unit concurrently, the installation timeline may extend to between 8 to 14 hours. This is because the installation involves additional steps such as removing and replacing both systems, ensuring compatibility, and making necessary adjustments for optimal performance.
  3. Minimal Disruption: We understand the importance of minimizing disruption to your daily routine during the installation process. Our team works diligently to ensure that the installation is carried out smoothly and efficiently, allowing you to enjoy your new air conditioning system as soon as possible.
  4. Customer Satisfaction: Your satisfaction is our top priority at Mainstream. We strive to exceed your expectations by delivering exceptional service from start to finish, including timely installation, thorough testing, and clear explanations of how to operate and maintain your new A/C unit.
  5. Post-Installation Support: After the installation is complete, our team remains available to address any questions or concerns you may have. We are committed to providing ongoing support to ensure that your new air conditioning system continues to perform optimally for years to come.

There are common warning signs you should know to look for, even if your HVAC system is still blowing air. If you notice any of the following, a problem may be present & it’s time to call the professionals at Radiant for air duct cleaning services:

Unexplained Sneezing and Congestion

Are you having breathing issues at home? Coughing? Sneezing? Congestion that doesn’t go away if you take allergy medication. As debris, mold, and dust accumulate in your ductwork, you breathe that in whenever you run the heat or A/C. This could be causing issues that mimic traditional allergies. If you notice unexplained cold-like symptoms, it may be time to get your ducts cleaned by Radiant.

Increased Energy Bills

If you notice a change in how your air is running, or your HVAC systems are having to stay on over extended periods of time, you may need to have your air ducts cleaned.

Unsure? One of the first places you’ll notice you need air duct cleaning is on your energy bill. When air duct cleaning doesn’t take place regularly, your HVAC systems will work less efficiently & leave a dramatic increase on your monthly energy bill.

It’s Been Years Since Your Last Duct Cleaning

You should get your ducts cleaned every three to five years. Most experts – including the National Air Duct Cleaners Association (NADCA) – recommend this time frame depending on how often you use your HVAC system throughout the year, if you have pets, or if you’re prone to allergies and colds.

No matter the problem, our expert duct cleaning technicians can determine what needs to be done before any work has started, so you know exactly what solution is best for your air duct system.
