New Construction

Whether you're a spec home builder, custom home builder, or building your own home, we cover all your HVAC construction needs. Partnering with multiple builders in Southern Utah, we handle hundreds of installations yearly. We offer a range of options, including standard and high-efficiency systems, zoning, hood range venting, bathroom exhaust venting, and dryer venting. All our systems meet local and state building codes, blower door, and duct leakage testing requirements, ensuring maximum comfort.


When your system fails, we thoroughly inspect it to identify any underlying issues. Mechanical failures often link to problems like improper duct sizing, dirty or restricted coils, or faulty electrical connections. Our technicians, regardless of the make or model, are trained to diagnose and repair these issues, ensuring you get the most out of your investment.


When it's time to replace your system, we understand it can be daunting with many brands, efficiency ratings, and high costs. Our technicians will recommend systems based on your performance and comfort needs, educating you on the differences between your current system and the suggested one. We will only suggest replacements if your yearly repair costs are approaching replacement costs, if a mechanical part is no longer available, or if your current system is improperly sized, causing discomfort.

Heating and Cooling Systems

In a packaged system, all equipment is built into an outdoor unit, usually on a concrete slab or other platform. The "package" that gives it its name provides central air conditioning during the summer and heat in colder months.

Air Conditioning

A traditional home comfort system has two parts: an indoor unit, such as a furnace or air handler, and an outdoor unit. An air conditioner is the outdoor unit that cools air and sends it to the indoor unit for circulation through your home. Indoor and outdoor units are designed to work together. When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life.


Furnaces heat and circulate warm air in the winter. Furnace heating ability is measured with an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.

High-Efficiency Heat Pumps

A high-efficiency heat pump is a heating and cooling system that maximizes energy transfer by utilizing advanced technology to extract and transfer heat between indoor and outdoor environments with minimal energy consumption.

Package Units

In a packaged system, all equipment is built into an outdoor unit, usually on a concrete slab or other platform. The "package" that gives it its name provides central air conditioning during the summer and heat in colder months


Thermostats are extremely important because they are your interface and control system for your heating and air conditioning equipment. This is the device that will give you the information on what the equipment is doing, when it needs to be serviced, and allows you to set the exact temperature and humidity you want to maintain in your home.


Zoning optimizes comfort and energy efficiency by independently controlling temperature levels in different areas or rooms of a building.

UV Air Purifiers

The benefit of UV air purifiers in HVAC systems is their capacity to eliminate airborne pathogens, such as viruses, bacteria, and mold spores, contributing to improved indoor air quality and potentially reducing the spread of illnesses.

Air Handlers

Distribute conditioned air throughout a building, ensuring consistent comfort levels and air quality.


Dehumidification can be very important if you live in areas of high humidity. High humidity in cooler temperatures gives you a wet clammy feeling and in warmer temperatures causes a wet sticky feeling and causes perspiration to stay on your body and soak in to you clothes rather than evaporate.

High humidity can also cause mold & mildew through out the house and even ruin very expensive clothes, fabrics, paintings & wall coverings. All air-conditioning units take out some humidity when they are running but in very humid areas this is not enough and you need a dehumidifying system.

Air Cleaners

Be sure your home's air is clear of dust, pollen, fungi, smoke and other particles too small to see. It's easy with a HEPA, Electronic or Media Air Cleaner. These cleaners provide stepped-up filtration, more effective than your furnace or air conditioner alone. In fact, these cleaners can remove up to 94 percent of the particles that pass through your home's system. And since these pollutants can build up as film on walls and furniture, this is performance you'll feel and see.

Evaporator Coils

A traditional home comfort system has two parts: an outdoor unit, such as an air conditioner or heat pump, and an indoor unit, such as a furnace or air handler. The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor where the cycle starts over again.


Energy Recovery Ventilator for warm climates or the Heat Recovery Ventilator for cooler regions, these air exchangers quietly bring in fresh, clean air from the outside and remove stale inside air, along with dust and other particle buildup.
