Your Frequently Asked Questions

  • Why do I need a system with matched components?

An air conditioner and furnace, a heat pump and furnace, a heat pump and air handler, an air conditioner and air handler, or an all-in-one "packaged" system can all be parts of a matched system. Matching systems guarantee maximum comfort, efficiency, and performance. For your home, a matched system will maintain optimum cycle times and manage humidity. A matching system will also stop you from incurring excessive energy costs. No energy will be lost owing to the wrong size, and your system will operate at maximum efficiency.

  • What can I do about my AC that's frozen?

Examine your evaporator coil to see whether you have a frozen unit or if your air conditioner is underperforming or stops pumping out cool air. It's advisable to turn off the unit and wait for the coils to thaw out if your air conditioner's coils are frozen before turning them back on. If you don't take care of your frozen AC right away, you risk major harm to your system. But if you think the issue is no longer within your control, then it is best to entrust the work to us. If you want it to get done as soon as possible, do not worry, as we offer dependable emergency HVAC services.

  • Do larger air conditioners operate more effectively?

No, not really. It's crucial to buy an air conditioner that fits your house properly. A larger air conditioner will cool your house more quickly, but it will also be less effective and less effective at removing humidity. There will be brief cycles in it. Although it cools the air rapidly, it won't pump enough air across the indoor coil to drain water from your system before it turns off. As a result, there will be too much moisture in the air, which may cause mold and mildew to grow within your house. If you need professional advice, do not hesitate to count on us, as we are best in HVAC repair, installation and maintenance. Hence, you can surely give trust to us, HVAC Alliance Expert
