Since 2002, Alexander Mechanical has offered professional design, installation, maintenance, and repair services for HVAC systems in residential, commercial, and industrial applications. For common questions and answers about our services and general heating, venting, and air conditioning queries, read on.

Our experienced technicians can install and service all major brands, including Rheem, Honeywell, Bryant, Activtek, Johnstone, and many more.

Over insulating and attic space and upgrading to a thermostatic ventilation system reduces monthly energy bills for heating and particularly cooling seasons. 

When a home or building has inadequate air exchange and/or ground seepage, it can create high humidity levels that result in mold. By keeping air movement and correct air exchange in a crawl space, relative humidity levels of 15 to 25% can be properly maintained. The right combination of dehumidistat, thermostat, and time will help maintain low humidity levels and protect against both frozen pipes and mold.

Here in northern Nevada, our climate is normally between 15 and 25% relative humidity. These low levels can aggravate conditions like allergies and negatively affect wood and wood products. With the right humidifier, it's possible to maintain humidity levels between 40 and 45% in your home. Plus, the systems we install track outdoor temperatures to automatically correct control setting at all times.

An air scrubber can help eliminate indoor air quality risks by reducing odors, air pollutants, smoke mold, bacteria, and viruses. The systems we install can reduce approximately 90% of airborne microorganisms in your home.

While an evaporative cooling system brings moisture into a residence, which is a benefit in our arid northern Nevada climate, these systems can only maintain a home temperature that is between 16 and 18 degrees cooler that the exterior air temperature. On a hot summer day in the low 100s, your interior temperature will hover between an uncomfortable 82 and 84 degrees. To achieve indoor home temperatures of your choosing, an air conditioning unit is needed.

Zoning systems give us the ability to treat different environments within your house accordingly. This might include the upstairs versus the downstairs spaces; basements; or guest rooms that are seldom used. Most importantly, a zoning system allows the control of differences in loss and load situations based on a home's orientation.
