What Are Signs It’s Time to Replace or Upgrade Your HVAC System?
Not sure if it’s time to upgrade? While some systems show obvious signs of failure, others slowly lose efficiency over time. Here’s some factors to consider when making that decision:
Is Your System 10-15 Years Old? Most HVAC systems start to lose efficiency and reliability after a decade, especially if they haven’t been well-maintained.
Have Your Been Scheduling Frequent Repairs? If you’re calling for service more than once a year, those repair costs can quickly outweigh the value of a new, more dependable system.
Are Your Energy Bills Continuing to Climb? Older systems have to work harder to keep up – leading to higher utility bills and reduced overall performance.
Is Your System Struggling to Keep Your Home Comfortable? Uneven temperatures, weak airflow, or rooms that never feel quite are all signs that your system is no longer up to the task.
Is Your System Constantly Running or Making Unusual Noises? If your system runs nonstop or you hearing banging, rattling or buzzing, it could be a sign of internal wear – or even something on the verge of failure.
Equipment Installation & Replacement FAQ
How long does a system replacement take?
Most residential HVAC system installations are completed in a single day, though timing can vary depending on the scope of work. The Mallick Team arrives prepared, works efficiently, and ensures your new system is fully tested and operating properly before we leave—keeping disruption to a minimum. If additional time is needed, our technicians will clearly communicate the situation and provide an updated timeline.
Do I need to replace both my heating and cooling systems at the same time?
Not always—but it’s often recommended. If your furnace and AC were installed together and one is failing, the other may not be far behind. Replacing both can improve efficiency, compatibility, and long-term performance. We’ll always walk you through the pros and cons based on your system and what you are experiencing.
Do you offer financing or rebate options?
Yes. We offer financing options through Synchrony, and many high-efficiency systems qualify for utility rebates or tax incentives. We’ll review what’s available and make the most of your investment for long-term comfort and savings.
