Frequently Asked Questions
What is HVAC?
HVAC stands for “heating, ventilation, and air conditioning.” It’s the central system used to provide heating and cooling to buildings.
Why is regular maintenance important?
Regular maintenance is crucial because it keeps your HVAC system running smoothly, and prevents costly repairs, saving you money in the long run.
Are all HVAC filters the same?
No. Filters for residential spaces are generally smaller than larger ones used in commercial buildings like businesses and hospitals. Choosing the right air filter has an important impact on your air quality. We’ll help you find the right one for your space.
Can indoor air be hazardous to your health?
Indoor air can sometimes be hazardous to your health if it contains harmful pollutants like carbon monoxide and mold. Luckily, M & D Mechanical, LLC has the tools, knowledge, and skill to identify any potential contaminants. We can also install an air quality monitor so you can ensure that your air stays fresh and clean.

The right humidifier for you depends on your needs. There are many different humidifier types, including cool mist, warm mist, ultrasonic, evaporative, and vaporizers. Consult with one of our professionals for recommendations on the right humidifier for you.
How often should I check my air filter?
You should be checking your air filter about every 30 days. For best results, arrange regular check-ups with us to make maintenance a breeze.
How often should I clean my air filter?
Generally, you should clean your home air filter about every 90 days. This timeframe can vary depending on the number of residents or pets. We recommend scheduling regular cleanings to keep your filter immaculate and your mind at ease. Residential air filters should be cleaned every 20-45 days, depending on the amount of foot traffic the building receives.
Should I have my air ducts cleaned?
Yes. Clogged air ducts can lead to shortness of breath, poor air quality, and erratic temperatures. Regular cleanings will keep these problems at bay and ensure you always have clean air.
