Air Conditioning Service

Pricing information will be provided by your HVAC contractor when they provide a quote for your overall job. The local  HVAC contractor will need to understand the specifics of your house’s and households’ cooling needs to provide this pricing. For instance, an HVAC contractor will need to estimate the capacity of your needed cooling system, as well as understand what elements of your previous cooling system need to be replaced. Please see our price guide for further details.

Sizing the equipment load requires the consideration of several factors. Ceiling height, construction, window size and placement, and dozens of other variables all need to be considered to properly size a cooling system. A professionally conducted load calculation is the foundation of an effective system.

At Mesa Heating & Cooling, we realize that purchasing a air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits.

There are many air conditioning systems to choose from today. Mesa Heating & Cooling can draw on a vast degree of air conditioning knowledge and experience to help you decide on the system that best fits your specific needs. The size and age of your home, as well as the number of rooms, climate, local and regional utility costs, and utility incentive/rebate programs are all factors that will affect the functionality and, therefore, selection of your system. Mesa, utilizing the latest technology, consider all these factors while assisting you in choosing the best system for your home. Consumers seeking to replace an existing system often choose a new unit with equal or higher efficiency ratings compared to their previous system. Replacing a unit that is 10- to 15-years-old may reduce electricity costs by 30 to 50%. Contact Mesa to help determine initial cost, warranty protection, service options, maintenance options, operating cost and proper installation.

A SEER (Seasonal Energy Efficiency Ratio) rating is a measure of the efficiency of air conditioning and heat pump systems. It is calculated by dividing the cooling output of a system (in BTUs) by the energy it consumes (in watt-hours) over a typical cooling season. The higher the SEER rating, the more energy efficient the system is. In the United States, the minimum SEER rating for new central air conditioning systems is 14, but systems with higher ratings are available and can be more energy efficient and cost-effective to operate. When shopping for a new air conditioning system, it is a good idea to consider the SEER rating.

The EER (Energy Efficiency Ratio) is a measure of the efficiency of air conditioning and heat pump systems. It is calculated by dividing the cooling output of a system (in BTUs) by the energy it consumes (in watt-hours) at a specific temperature. The higher the EER rating, the more energy efficient the system is.

EER ratings are typically used to compare the efficiency of different systems at a single outdoor temperature. For example, an air conditioner with an EER of 10 will be more energy efficient than one with an EER of 9 when both systems are operating at the same outdoor temperature.

In the United States, the minimum EER rating for new central air conditioning systems is 9.7, but systems with higher ratings are available and can be more energy efficient and cost-effective to operate. When shopping for a new air conditioning system, it is a good idea to consider the EER rating.

Properly sizing an air conditioning system is important to ensure that it is able to effectively and efficiently cool the space it is intended for. There are several factors to consider when sizing an air conditioner, including the size and layout of the space, the number of windows and doors, the level of insulation in the space, and the local climate.

To size an air conditioner, you will need to determine the cooling load of the space. This can be done using a variety of methods, such as manual calculations or specialized software. Some common factors to consider when determining the cooling load of a space include the size of the space, the amount of insulation, the type and number of windows, the orientation of the space relative to the sun, and the number of people and appliances that generate heat.

Once the cooling load has been determined, you can use this information to select an air conditioner that is appropriately sized for the space. It is generally recommended to choose an air conditioner that is slightly larger rather than smaller, as an undersized unit may struggle to keep the space cool, while an oversized unit may waste energy and may not provide consistent temperature control.

It is important to note that proper installation of the air conditioner is also crucial for ensuring that it operates effectively and efficiently. A professional HVAC contractor should be consulted to ensure that the unit is properly sized and installed.

Two-stage cooling utilizes a multi-, or two-speed compressor. A high-stage demand from the thermostat will cause the compressor and circulating fan to operate at 100% cooling capacity and the indoor fan to operate at the high-speed setting designated at the furnace or air handler. A low-stage demand from the thermostat will result in a 35% speed reduction at both the compressor and indoor unit circulating fan. Two-stage cooling generally results in extend operation at low speed removing more moisture from the structure, providing more comfort and using less electricity than single-stage systems.

The AHRI directory contains rated values for air conditioners and heat pumps.  These explain how a “split system”, which is an outdoor unit and an indoor unit, perform as a paired set.  This is a more precise measure for the equipment that you are considering for your home.  EER, SEER and HSPF, the most common measures of a units efficiency.

Variable-speed cooling (and heating with heat pump models) is driven by a variable-speed compressor providing premium cooling performance which can result in considerably lower energy bills and improved indoor comfort compared to heat pumps with a single-stage compressor.

Covering the outdoor unit in the winter months prevents unwanted debris from accumulating on the outdoor unit and later impeding airflow to the outdoor unit. At the same time accidentally operating the outdoor unit with a covering in place could cause system damage. It is recommended that high voltage power always be disconnected from the outdoor unit whenever a cover or anything obstructing airflow is introduced.

Here are several tips to help you keep your HVAC system running efficiently:

• Change the air filters every month or as directed by your system’s manufacturer.

• Cut back foliage and remove any leaves, grass trimmings, or debris left by nearby dryer vents that might be blocking airflow to the air conditioner or heat pump.

• Have your system serviced by a licensed professional HVAC contractor before peak season.

• Cooling systems work incredibly hard to perform their functions for your household. The constant stopping, starting and continual operation can wear down a machine quickly and unexpectedly if the proper care and maintenance is delayed. However, by performing preventive maintenance, or servicing your system regularly, you can maximize the life-cycle of your cooling unit and guard against many unexpected failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, frayed wires and corroded electrical contacts.
