Frequently Asked Questions

  • How does a ductless mini split system work?

    A ductless mini split uses an outdoor compressor and indoor air handlers to deliver heating or cooling directly to specific rooms without ductwork. It's ideal for room additions, offices, and older homes without existing ducts. At Perfect Degree HVAC, we install systems suited for Pennsylvania's mixed climate and tight building layouts.

  • When should you schedule HVAC maintenance in Pennsylvania?

    Schedule heating maintenance in early fall and cooling maintenance in early spring to prepare for extreme seasonal demands. Routine service extends system lifespan and reduces unexpected breakdowns. Perfect Degree HVAC aligns maintenance timing with Drexel Hill's cold winters and humid summers.

  • What are the benefits of whole-home humidifier installation?

    Whole-home humidifiers add moisture to dry indoor air during Pennsylvania winters, improving comfort, reducing static, and supporting respiratory health. They integrate with existing HVAC systems for consistent humidity control. At Perfect Degree HVAC, we address regional climate challenges common in Drexel Hill and surrounding areas.

  • What's the difference between a furnace and a boiler?

    A furnace heats air and distributes it through ducts, while a boiler heats water that circulates through radiators or radiant floors. Boilers are common in older Pennsylvania homes with hydronic systems. Perfect Degree HVAC services both types and understands regional building styles throughout Delaware and Chester County.

  • Why do mini splits work well in older homes?

    Mini splits don't require ductwork, making them perfect for older homes without existing ducts or limited space for installation. They provide efficient zoning and temperature control in individual rooms. Perfect Degree HVAC is familiar with Main Line housing layouts and space constraints common in Drexel Hill.

  • How often should duct cleaning be done?

    Most residential and commercial properties benefit from duct cleaning every three to five years, or sooner if there's visible dust buildup or airflow issues. It improves indoor air quality and system efficiency. Perfect Degree HVAC regularly works with aging ductwork found in older homes across the region.

  • What affects the cost of generator installation?

    Generator cost depends on system size, fuel type, installation complexity, and whether existing infrastructure supports connection. Larger homes or properties with critical equipment needs require bigger systems. At Perfect Degree HVAC, we size generators based on property demands and local outage risks in Pennsylvania.

  • Can a mini split heat and cool the same space?

    Yes, ductless mini splits provide both heating and cooling from a single system, making them versatile year-round solutions. They're efficient in Pennsylvania's fluctuating shoulder seasons and extreme winters. Perfect Degree HVAC installs systems designed for zoning and temperature control in residential and commercial spaces.

  • What's the biggest mistake people make with heating systems?

    Skipping annual maintenance is the most common mistake, leading to reduced efficiency, higher energy bills, and unexpected breakdowns during cold weather. Regular service catches small issues before they escalate. Perfect Degree HVAC recommends fall checkups to handle Drexel Hill's harsh winter heating demands.

  • Do boilers work well in Pennsylvania winters?

    Yes, boilers provide reliable, consistent heat ideal for Pennsylvania's cold winters and are common in older regional homes. They distribute warmth through radiators or radiant floors without forced air. Perfect Degree HVAC services hydronic heating systems throughout Drexel Hill and surrounding communities.

  • How does thermostat installation improve energy management?

    Modern thermostats offer programmable schedules, remote access, and multi-zone control, reducing energy waste and improving comfort consistency. Upgrading older systems can lower heating and cooling costs. At Perfect Degree HVAC, we support compatibility with older HVAC equipment and newer multi-unit setups.

  • What should you know before installing a generator?

    Determine your essential power needs, choose between natural gas or propane fuel, and confirm local permits and installation requirements. Proper sizing prevents overload or insufficient backup power. Perfect Degree HVAC evaluates property needs and local infrastructure to design reliable backup solutions for storm-related outages.
