Air Handlers

It works in tandem with your heat pump or air conditioning system, pulling in return air, passing it through filters, conditioning it to your desired temperature, and distributing it through your ductwork. Without a properly functioning air handler, even the most advanced outdoor unit cannot deliver comfortable, consistent temperatures to every room in your building.

At Gillette Services - Plumbing, Heating and Air Conditioning, we install, repair, and maintain air handlers for residential and commercial customers throughout Spanish Fork, UT & the surrounding areas. As a locally owned and family-operated company committed to putting our customers and employees first, we understand how important indoor comfort is to your daily life. Whether you are building a new home, replacing an aging system, or troubleshooting performance issues, our team has the expertise to ensure your air handler operates at peak efficiency year-round.

Key Components Inside an Air Handler

An air handler is much more than a simple fan in a metal cabinet. Inside, you will find several essential components that work together to deliver clean, temperature-controlled air. The blower motor is the heart of the unit, responsible for pushing air through the ductwork at the correct volume and speed. Modern variable-speed blower motors can adjust airflow dynamically based on demand, reducing energy consumption by as much as 50 percent compared to older single-speed models. The evaporator coil sits inside the air handler and is where heat exchange occurs, either absorbing heat from indoor air during cooling mode or releasing heat during heating mode when paired with a heat pump.

Air filtration is another vital function performed within the air handler. Standard units accommodate filters ranging from basic fiberglass panels rated at MERV 1 through high-efficiency media filters rated at MERV 13 or above. Higher-rated filters capture smaller particles including pollen, dust mites, mold spores, and pet dander, significantly improving indoor air quality. Some air handlers also integrate UV germicidal lights or electronic air cleaners for additional purification. When we service your air handler, we inspect every one of these components and provide honest recommendations based on what we find.

Signs Your Air Handler Needs Attention

Recognizing when your air handler is struggling can save you from expensive emergency repairs. Common warning signs include unusual noises such as rattling, squealing, or humming that indicate worn bearings, loose components, or electrical issues. Reduced airflow from your vents often points to a clogged filter, failing blower motor, or obstructed ductwork connected to the air handler. Inconsistent temperatures from room to room may suggest the blower is not distributing air evenly, potentially due to a speed setting issue or duct imbalance.

Higher-than-normal energy bills are another red flag. According to the U.S. Department of Energy, heating and cooling account for roughly 48 percent of energy use in a typical American home. A malfunctioning air handler forces your entire system to work harder, driving those costs even higher. We offer fast response times and take responsibility in our work, so when you call Gillette Services - Plumbing, Heating and Air Conditioning, you can expect a thorough diagnostic and a clear explanation of what needs to be done.

Air Handler Installation and Replacement

When it is time for a new air handler, proper sizing and installation are absolutely essential. An oversized unit will short cycle, creating humidity problems and uneven temperatures. An undersized unit will run constantly without adequately conditioning your space. Our technicians perform Manual J load calculations to determine the exact capacity your home requires based on square footage, insulation levels, window orientation, climate zone, and occupancy patterns.

During installation, we focus on several factors that directly impact long-term performance and efficiency:

• Ductwork connections must be properly sealed to prevent conditioned air from leaking into unconditioned spaces like attics or crawlspaces
• Condensate drainage lines need correct slope and clear pathways to avoid water damage and mold growth
• Electrical wiring and controls must meet local code requirements and manufacturer specifications for safe operation
• Vibration isolation pads or mounts should be installed to minimize noise transmission through your home’s structure
• Thermostat compatibility needs verification to ensure proper communication between the air handler and your control system

Preventive Maintenance for Long-Term Performance

Regular maintenance extends the lifespan of your air handler and keeps it running efficiently. We recommend scheduling professional tune-ups at least twice per year, ideally before the heating and cooling seasons begin. During these visits, our technicians clean the evaporator coil, inspect the blower motor and capacitor, check refrigerant levels, test electrical connections, and replace filters. These steps help prevent breakdowns and maintain manufacturer warranty coverage.

We take great pride in serving our community and giving back whenever possible. Our community initiatives include providing free furnace installations to families in need during the winter season, contributing to the HVAC installation for the St. Jude Dream Home, and supporting the Children’s Justice Center’s new facility.
