AIR CONDITIONING HEATING AND VENTILATION

Air Conditioning Repair

In Arizona, a broken air conditioner during the summer becomes a life or death situation. MechaniCool is always ready to have a technician at your door in a timely manner. Our technicians are able to fix most issues in one visit, with service trucks fully stocked with common parts for all brands and types of systems.

We provide service 24 hours a day, 7 days a week. You cannot control when your AC system quits working, so we don’t charge extra for after-hours, weekends, or holidays for Emergency Service.

While some HVAC system problems are a matter of comfort, others are a matter of safety. If you are in doubt, don’t hesitate to call us and ask whether you should have your unit immediately serviced.

Sometimes repairing your existing system doesn't make financial sense due to the cost of current or future repairs, or the lack of system efficiency. Our technicians will provide you with all of the options, including system replacement so you can make the best decision for your family.

Installing New AC Equipment

MechaniCool takes extra care to ensure that your new comfort equipment is installed properly. In conjunction with you, the homeowner, we determine the right solutions to improve comfort and increase energy efficiency in your home.

The typical lifespan of a cooling system in the Southwest is 10-15 years. Although an older unit may still be functioning, the decrease in energy efficiency or major component repairs may be adversely affecting you financially in the long run.

In Arizona there are typically 2 types of cooling systems in 2 configurations dependent on how your home was constructed.

Heat Pump systems are typically used in areas where natural gas is not available (although can be used in homes that have other natural gas appliances). A heat pump uses all components of the system in both heating and cooling.

Straight Cool with Gas Furnace uses natural gas for heat. The condensing unit is used only during the cooling function. Heating uses only the furnace. Both heating and cooling use the blower motor.

Split System means that there is an outdoor unit (condenser) and components in the attic or a closet in the home or garage, often referred to as the indoor unit. The indoor unit is typically an air handler (heat pump), or a furnace and coil (gas), both have a blower motor.

Packaged System normally is roof mounted, although in some areas they do sit on the ground. These can either be a heat pump system or straight cool with gas. All components are packaged into one piece of equipment.

There are some systems, usually found in manufactured homes, that utilize electric heat instead of gas or heat pump.

Proper installation of a new system is essential for optimal operation of the equipment.

Some things we do to ensure a quality split system installation include;

• New electrical whip and disconnect box with fuses, knowing new equipment should not be installed with aged electrical components.
• Replacement of supply and return plenum boxes fabricated to the new unit specifications for a tight fit.
• Unistrut and All-thread suspension system for attic components to ensure level. Chains tend to stretch over time with the expansion and contraction of the metal rings.
• Moisture safety switch and secondary drain pan to protect your home in the event of a condensate drain clog.
• Vacuum refrigerant lines to below 500 microns to ensure removal of any moisture or aero-noncondensibles and facilitate efficient flow of refrigerant
• Ensure that the return duct is large enough for proper air exchange, and either enlarge or add an additional return when needed.
• Contract with repair professional to return attic access to pre-installation condition. We often need to remove the access trim, or the drywall around the access is damaged when removing and placing new equipment in the attic.

Some things we do to ensure a quality package unit installation include;

• New electrical whip and disconnect box with fuses, knowing new equipment should not be installed with aged electrical components.
• Replace unit stand and unit elbow, fabricated to the new unit specifications for a tight fit.
• Ensure that the return duct is large enough for proper air exchange, and either enlarge or add an additional return when needed.
• Contract with a fully insured crane service to remove old system and lift new system onto the roof.

No matter the system application you can expect MechaniCool to install your comfort systems using the highest quality, professionalism, and expertise.

What you can expect on the day of your installation:

• Our installation team will arrive in the designated arrival window ready to go with all materials needed to complete your job.
• Installers wear shoe covers on carpeted surfaces to lay down drop cloths or plastic to protect your home.
• Your old equipment will be removed and placed in a confined area near the curb to allow for pick up by our disposal company.
• Once installed our team will conduct a series of test to ensure a safe and proper installation was completed.
• The lead technician will demonstrate thermostat operation and functions.

Depending on the time of year your new system is installed, an additional visit may be needed to commission the cooling function of your equipment.
