I was having a problem with my Nest thermostat. This is the 3rd house I’ve installed a nest, but for whatever reason I could not figure out how to get the settings right for this system. Damir came to my house the same day I contacted, and within an hour had diagnosed the problem and now it’s running flawlessly.

We have used 365 Mechanical to replace our AC unit in our house and then, liked their quality and service so much, had them install an air conditioning unit in our garage without getting quotes. We knew their work ethics and their fair pricing. We have since had them come and do regular maintenance. They are a great company to work with. We highly recommend them!

365 Mechanical has provided service to my home for years. Their technicians are always prompt, knowledgeable, and will provide honest and up-front information about the state of our AC system and vents. With their services, our AC system has stayed in proper working condition. They did everything they could to answer an emergency call when our AC system shut-down in the middle of summer and exceeded our expectations on a response time. They are also very clear and fair about their pricing and will not surprise you with costs.

Air Conditioning Installation Questions

Maintaining your AC’s peak performance and lifespan depends on your system’s age and usage. Generally, aim for professional servicing twice a year – pre-season tune-ups in fall and spring. Consistent maintenance isn’t just about comfort but safety and protecting your investment.

Older air conditioners typically last 10-12 years, while newer AC installation models can provide performance for 15-20 years. Proper AC maintenance plays a vital role in extending lifespan and maximizing efficiency.

Air conditioning (AC) installation typically encompasses several key steps to ensure optimal functionality and efficiency. Firstly, a qualified technician conducts a thorough assessment of the space, considering factors like size, insulation, and ventilation. Following this, the installation involves positioning the indoor and outdoor units strategically for effective cooling. The technician then installs the necessary electrical components, connecting the system to the power supply. Refrigerant lines are carefully fitted to facilitate the transfer of heat, and a proper drainage system is established to manage condensate. Additionally, the installation includes the configuration of thermostat settings and testing the entire system for functionality and safety. Comprehensive AC installation aims to maximize cooling performance, energy efficiency, and longevity, emphasizing adherence to manufacturer guidelines and local building codes. Professional installation ensures optimal comfort and minimizes the risk of malfunctions or inefficiencies.

We provide same-day and emergency 24/7 AC Installation service year-round! Rest assured, we understand the importance of cool air in Arizona for a comfortable home. And we never start work without quoting AC unit installation costs!

Watch for these warning signs to determine whether your unit requires maintenance. If your Mesa air conditioner isn’t cooling correctly, has weak and uneven airflow, produces condensation, or makes strange noises – it’s a good idea to contact the experts.

First, schedule a yearly HVAC inspection to ensure maximum efficiency and lower costs. Second, invest in a programmable smart thermostat to control temperatures while you’re away, saving energy and money. Third, leaking ducts waste energy. Get them sealed and insulated for maximum efficiency.

The installation process for an air conditioner typically spans a duration of 4 to 8 hours. However, the specific timeframe may vary based on factors such as the size of the existing system, prevailing weather conditions, and accessibility considerations.

The components of an air conditioner comprise the indoor evaporator coil and the outdoor condenser. The installation commences with a meticulous assessment of the installation site, ensuring alignment with optimal performance parameters. Subsequently, technicians position the indoor and outdoor units strategically and interconnect them with refrigerant lines. Electrical components are installed, and a drainage system is established. The overall process concludes with the configuration of thermostat settings and a comprehensive system test to ensure functionality and safety. The duration of installation remains contingent on various variables, underscoring the need for meticulous attention to detail during the installation procedure.
