HVAC Contractor Licensing In A/C Maintenance, Upgrades and New Installations

Whether residing in Washington, DC, Charlotte, NC or Mesa, Arizona, every homeowner eventually encounters the concept of construction permits and/or contractor licensing. The necessities of a building permit change from region to region and with accordance to the scope of a given project. However the importance of always working with a properly licensed HVAC contractor will never change. You should accept air conditioning services only from a bonded, insured and licensed Mesa air conditioning professional.

Purpose of HVAC Permits and Licenses

By nature, a building permit is designed to provide reasonable assurances that a home is safe from structural failure, electrical shock, undue health risks, and fire hazards associated with electrical components and home heating and cooling systems. They also help homeowners and city officials ensure that housing contractors have a valid contractor’s license for services within a specific geographical location and for performing a specific work task within that location. Furthermore, permits and evidence of contractor licensing can be useful during the sale or refinancing of a home. In many regions of the nation, prospective lending institutions require proof that existing alterations to the home were performed in compliance with local codes. 

However, not every home improvement or home structural change requires that the homeowner take out a building permit. According to the Mesa-AZ online government resource page, Mesa-related building permits are only required when a structural change or major alternation is performed on an existing building or when any new construction project is undertaken. Each separate process of the construction requires a distinct and separate permit. Examples of processes requiring permits include:

  • Electrical Work
  • Mechanical Work
  • AND Plumbing Work.

Processes that do not require a permit are many, including installing new cabinets, roofing materials, window awnings, and various plumbing activities. However, most of these projects do include exceptions wherein some aspects of such projects may require your contractor to take out a building permit in your behalf.

Mesa HVAC Permit Specifics

When dealing with HVAC equipment in Mesa, no permit is required if your contractor is changing out a unit with a system in the same tonnage. However, permits are required on all new installations. Before signing your contractor make sure you know who will accept the responsibility for obtaining any necessary permits.


Effective A/C Maintenance Promotes Better Home HVAC Equipment Performance

A host of issues affect the cost of home heating and cooling. Adding heavy window drapes, additional attic installation and better sealing the doors are steps that you can use when striving to reduce the cooling load on your home. You can also switch over to more natural cooling processes such as electric fans, open windows, and specialty A/C water cool systems. Simple steps like bumping the thermostat up a few degrees can also reduce the cooling expenses.

System tune-ups and annual scheduled HVAC maintenance helps ensure that your existing equipment is prime-functional for it’s capacity. In older homes with aging air conditioning systems, upgrading to a new energy-efficient heat pump will likely produce a dynamitic decrease in the system’s energy consumption level.

Factors Involved – A/C Maintenance in a Nutshell

Once deficiencies are discovered, you must define the actions necessary for correcting the revealed problems.

Typically, you work with a appropriately licensed Mesa HVAC contractor.
