Most Commonly Asked Questions

Is it better to have a larger HVAC system?

Often, we think bigger is better; however, when it comes to your HVAC system, use the Goldilocks Principle.  Whether a residential home or business, you want to use a system that matches the size of the space. Oversized systems can drastically increase energy costs and can result in unreliable heating and cooling cycles, poor humidity removal, and can lead to damage and shorter life spans for your HVAC system. Undersized systems are also a problem in that they do not perform as needed.

You should always speak to a professional HVAC company when sizing a system for your space.  Milton Mechanical Services provides advice and strategies at no cost for making these decisions.

2 - How severe (costly) the problem is to repair?

3 - How much time it will take to obtain parts and make the repair?

4 – What refrigerant does the system use?

5 –  How energy efficient is the current unit?

How long will my HVAC system last?

It is difficult to determine how long any system will last. Modern, high efficiency systems use higher pressure refrigerants and smaller heat conducting components.  They do not last as long as older, low pressure, low efficiency systems.

Keep your system running as long as possible by:

1. Performing Regular Maintenance (Milton Mechanical Services provides a maintenance program that checks the system at the start of each season) 

2. Choosing an expert equipment installation company that uses modern methods and techniques to install equipment.

3.  Make sure that the equipment operates in an optimum environment – clear of debris.
