HVAC System Design & Installation

Understanding HVAC Systems

What is the difference between an HVAC and an Air Conditioner System?

An HVAC system is a comprehensive system that provides both heating and cooling functions as well as ventilation for a building. It encompasses several components that work together to control the indoor environment and maintain comfort.

Key Components of an HVAC System

Heating Unit

This component provides heat during cold weather, often using methods like a furnace, heat pump, or electric heaters.

Air Conditioning Unit

The AC unit within the HVAC system is responsible for cooling the indoor air during hot weather, using a refrigeration cycle to remove heat from the air.

Ventilation

Ventilation systems ensure a constant supply of fresh outdoor air while expelling stale indoor air. They may include fans, ducts, and air exchange systems.

Ductwork

Ducts distribute heated or cooled air throughout the building, ensuring consistent temperature control.

Thermostat

A thermostat is used to set and control the desired indoor temperature.

HVAC systems are designed to maintain a comfortable and healthy indoor environment year-round, offering both heating and cooling capabilities.

Qual-Tech was recommended and we are very pleased with their service. John was very professional and friendly over the phone. Christian was attentive and very informative with servicing our unit. We will definitely be using Qual-Tech again for our a/c needs. Thank you!

Qual-tech saved the day! 112 degrees today. John was able to get his technician, Christian, out the same day that they received the request. Christian arrived on time and took about 10 minutes to diagnose and to make the fix (he says it was the dual capacitor). Now, we just have to wait for the house to cool from 91 degrees. 😬 Thank you, gentlemen!

We recently had our 17-year-old HVAC replaced by Qual-Tech. From the first technician we met, George, to their install manager, Christian, and the entire install team, we were very impressed by their professionalism, honesty, timeliness, and courtesy. The owner, John, was always available to answer questions and did a great job communicating throughout the process. I highly recommend Qual-Tech for anyone looking for knowledgeable and quality HVAC service!

The Qual-Tech team were amazing to work with. Their followup was excellent. The gentleman that came out, George, was very knowledgeable and took the time to explain what the issue was. He was very careful entering the attic access inside the house and cleaned up once he finished. Everything is working fine, thank goodness with the cold weather that has entered the Surprise area. I would highly recommend Qual-Tech air conditioning / heating to anyone.
