"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

Customers say: True professional

"We hired McCormick to remodel our master bathroom, and the process couldn’t have been smoother. Khaled guided us through everything, and his team was skilled and respectful. They handled the job efficiently, stayed within budget, and kept our home tidy. Now, our bathroom feels like a relaxing oasis, with high-quality finishes and a modern touch we love. McCormick’s attention to detail really made the difference, and I’d gladly hire them for future remodels. This experience was everything we hoped for."

There are some physical signs you need to have a humidifier that manifest as signs in your home and body.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

No, air purifiers neither cause dry air nor increase the home's humidity levels. They remove allergens and dust but don't alter the water content in indoor air. However, because some air purifiers move large volumes of air, the areas immediately surrounding a portable unit can feel cooler and dryer than the rest of the home.

Several styles of HVAC dampers exist, some with motors and some without. The various types include butterfly, blade, louvered, guillotine, and more. The names describe their construction style and how air moves through them. Motorized versions work through wiring connected to a control panel within the HVAC system. Manual versions allow an operator to decide which way to send the airflow and make the adjustment by hand.
