Liberty Lake Residential HVAC Installation

All of our residential HVAC installations are a three-step process:

  1. Home Evaluation
  2. Installation
  3. Follow Up and Maintenance

Home Evaluation

Your residential HVAC installation begins with a total home evaluation. Our trained technicians will come to your home and inspect your house from top to bottom. In the process, our HVAC experts will come up with the best plan to meet your residential HVAC goals.

We take into consideration a variety of factors from the size of your home to the surrounding geography to the size of your budget. How long you intend to live in your home is a crucial input, as some HVAC systems are more costly up-front but offer more savings for homeowners who remain in their homes for many years.


The day of your residential HVAC installation is the single most important event in the life of your heating and cooling system. Up to 75% of the efficiency of your HVAC system depends upon the proper installation of your unit. Unlike many other domestic mechanical devices, an HVAC unit will not operate properly if it is incorrectly installed. Peak-efficiency and long-life are both negatively effected by improper installation.

All of our expert technicians are trained in residential HVAC installation, as well as the installation of all necessary ductwork, venting and sheet metal. At AMS, we’ve got you covered.

Follow Up and Maintenance

We guarantee our work, which is why we follow up with our customers to ensure that their HVAC goals are being met after installation. If something is wrong with your new heating or cooling unit, we will fix it.

We recommend regular annual maintenance. No mechanical system lasts forever without maintenance. All the units we install are rated for long lifespans, but annual maintenance is crucial to keeping your unit running for years to come.

Liberty Lake Residential HVAC Maintenance

At AMS, we offer three Liberty Lake residential HVAC maintenance plans:

  • Monthly
  • Annual
  • Semi-Annual

The maintenance needs of your particular residential unit will depend upon the type of system you have installed and the amount of use your system gets throughout the year. After installation, our experts will work with you to determine the best strategy for maintaining your system.

In addition to our professional residential maintenance plans, we have also created an HVAC Maintenance Checklist and a Seasonal HVAC Maintenance Schedule to help guide you throughout the life of your heating and cooling system.
