What kind of refrigerants do you use?

R407, R404, R410
Are there any seer rating changes coming and what is the change?

Beginning January 1, 2023, there will be two SEER-related changes. First, the minimum SEER rating will increase on HVAC equipment. Currently, new air conditioners must have a minimum SEER of 13 in northern states and 14 in southern states. In 2023, this will change to 14 and 15, respectively.
Do you offer duct sealing services to improve energy efficiency?

Yes, we use an excellent subcontractor and will facilitate the process on behalf of our customers.
Are there any rebates or incentives to upgrade my hvac system to be more energy efficient?

Not at this time. Follow us or Subscribe to our Newsletter for any changes to the rebate programs.
Do you offer a warranty on your work?

We offer a full year for all labor and materials, and new AC systems come with a 10 year warranty.
Do you have maintenance plans and what are the details?

Yes, This is what is generally included. 1. Replace air filters supplied by Mechanical Air Design. 2. Inspect the equipment for rust and/or corrosion and provide feedback to the customer should the deterioration be extensive. 3. Clean/clear condensate drain line and treat with DrainSolve, if necessary. 4. Inspect High and Low-Pressure Controls and inspect for any visible and/or obvious refrigerant leaks. 5. Inspect electrical wiring and controls in both the AHU & CU. 6. Check and verify refrigerant pressures. 7. Check, tighten and clean contactors, capacitors and all other electrical equipment. 8. Check overall equipment for full functionality and efficiency Contact us today for a Free Evaluation and Estimate

The Owner and license holder attends continuing education every 2 years, and all staff takes quarterly classes on new industry standards, new equipment training and courses on future technology
What are the benefits of clean indoor air?

Children and elderly people are more susceptible to respiratory problems, so they can benefit greatly from cleaner air. People who suffer from allergies or asthma can experience fewer symptoms when the air is cleaner. Office workers can experience less headaches and eye irritation when the air is cleaner. People who work in environments where they are exposed to pollutants, such as construction sites or laboratories, can also benefit from cleaner air.
How can my HVAC system improve my indoor air quality?

Installing an air purification system that uses UV-C lights to kill mold and bacteria Regularly replacing air filters to capture particles and allergens Using humidifiers to maintain the appropriate level of humidity in a building Sealing ducts to prevent leaks and improve air flow.
How will I know if my indoor air quality could be improved?

• A musty smell in a basement due to mold growth • Dust and pet dander accumulating on surfaces • A strong chemical smell in a building that uses cleaning agents or pesticides. • High levels of carbon monoxide or other dangerous gases
What can happen if I do not perform proper maintenance?

1. Reduced efficiency: Over time, HVAC systems can become clogged with dirt, dust, and other debris, which can reduce their efficiency and cause them to work harder than they need to. Regular maintenance can help to keep systems clean and running at peak performance. 2. Increased energy costs: When HVAC systems are not running efficiently, they can consume more energy, which can result in higher energy bills. Regular maintenance can help to reduce energy consumption and lower costs. 3. Reduced lifespan of equipment: HVAC systems that are not properly maintained are more likely to experience breakdowns and malfunctions, which can shorten their lifespan. Regular maintenance can help to prolong the life of the equipment and prevent costly repairs. 4. Poor indoor air quality: HVAC systems are responsible for circulating and filtering the air inside a building. If they are not properly maintained, they can fail to remove pollutants, allergens, and other contaminants from the air, which can lead to poor indoor air quality and a variety of negative health effects. 5. Increased safety hazards: HVAC systems that are not properly maintained can be a safety hazard. A lack of maintenance can cause systems to overheat, which can lead to fires or other accidents. 6. Reduced comfort: If your HVAC systems are not functioning properly, it can lead to uncomfortable temperatures in your home or office, making it hard to focus or relax.
What is the evaporator coil and fan blower?

The evaporator coils and fan blower motors in the air handling unit are critical components of an HVAC system, as they are responsible for cooling and circulating the air throughout the home or building. The evaporator coils absorb heat from the indoor air, which is then blown over the coils by the fan blower motor to cool the air.
What is the compressor and condensing fan?

The compressors and condensing fan motors in the condenser are also important components of an HVAC system. The compressor pressurizes the refrigerant, which is then cooled by the condensing fan motor. This cooled refrigerant is then circulated through the evaporator coils to absorb the heat from the indoor air.
What are the electrical parts of an HVAC system?

The electrical parts of an HVAC system, such as capacitors, contactors, control boards, electrical disconnects, wiring harnesses, etc. are also important and need to be maintained. These electrical components control the operation of the HVAC system and if they fail, it can cause the system to malfunction.
How important is ducting?

Ducting is responsible for distributing the cooled or heated air throughout the home or building. Types of ducting for residential and commercial include fiberglass and sheet metal.
