Whats in your Air Conditioner?


The HVAC unit providing comfort for your family at home or for your employees at work has seen better days and you are now getting ready to have a new unit installed. Whether you are replacing your old equipment because it wasn't functioning very well or simply because you are interested in using the latest in efficient technology to lower utility costs, you will naturally want to have a good idea of what to expect when the technicians arrive.

After you set an appointment for installation, you can expect to get a confirmation call the day before service. We will be happy to give you a call or text message on the day service of as well, giving you a heads up that we are near your location.

How Removal of the Old Unit Works

First, you should know that your HVAC technicians will treat your home or business as if it was their own, in terms of keeping everything clean. We aim to cause minimal disruption and will strive to work around your schedule at work or at home.

The technician inspects your HVAC setup and will then bring in all necessary tools and equipment from the truck. Then, it's a matter of turning off the power and disconnecting the old unit. At this time, we also drain all coolant for proper disposal.

How Long Should Installation of a New Unit Take?

Prudent homeowners and business owners will rightly want to get an idea of how long installation of a new unit should take. Keep in mind that each home or place of business will have unique characteristics, which makes it difficult to give a general timeframe for installation.

However, you can expect that it will take about 4 to 10 hours to install just a new furnace unit and about 4 to 8 hours for an AC unit installation. If installing a new furnace and AC unit, it may take 8 to 14 hours. Most installation jobs will be completed within one day. However, a more complicated installation could take two days.

Each job has its own unique circumstances, so it's best to consult with your HVAC professional to get a clearer idea of how much time the job will take at your home or business.

Questions to Ask Installers Before They Leave

You may have a few questions post-installation. For example, make sure that the technician explains to you how to program the new thermostat.

Since HVAC equipment requires periodic inspections, cleaning and maintenance to run as efficiently as possible, ask, the technician about what maintenance programs are available, such as to come once per year.

Your new equipment should be expected to function perfectly. However, if a problem arises, you'll want it taken care of immediately. For greater peace of mind, ask the technician what number to call for 24-hour emergency service.

Installing new HVAC equipment is a big investment and it's always best to go with professionally trained technicians who have many years of experience, like the team at David Gray Heating & Air.
