HVAC Frequently Asked Questions

I’ve been working in the HVAC field for more than 20 years, including my time in the Air Force, when I learned this skill. Over the years, I’ve fielded numerous questions concerning various systems used in both residential and commercial settings. I always respond with the customer’s best interests in mind, understanding that acting in their best interests will increase their faith in me. The equipment has evolved over the past few years to become increasingly sophisticated and efficient. In order to be the authority  or expert for my customers, I have kept up with every update and upgrade in this industry. Many of the most frequent questions are represented in the list below. Please get in touch with me if you have any more queries or concerns, and I will try my absolute best to assist you.

How often should I have my HVAC system serviced or maintained?

HVAC systems should be serviced at least twice a year (in the spring and the fall). I compare HVAC systems to automobiles. To keep them operating, they require regular maintenance. Abel Mechanical Services has available a service plan that will keep your system running smoothly all year round. Contact us for pricing and additional information.

What is the most energy-efficient temperature setting for my thermostat during different seasons?

Normally, I recommend keeping your home at 74 degrees, but it also depends on the energy KW cost terms you have with your energy supplier. You’ll also save money with a calibrated thermostat and a regularly serviced system. There are thermostats that can keep up with your temperatures throughout the year so you can get the best value for the dollar. Contact us with any further questions you may have.

How can I lower my heating and cooling costs without sacrificing comfort?

Ensure that your HVAC system receives its regular maintenance. Be sure to seal and examine ductwork at least once every one to two years. There are also programable thermometers that can assist in keeping your costs down. They fluctuate service during the day and night so that you may be comfortable and cost conscious.

What is the average lifespan of an HVAC system, and when should I consider replacing it?

In recent years, HVAC system components have become more complicated in an effort to be more efficient. With this comes more components, features and moving parts. It’s all machinery, so the amount of use your system gets and how well it’s taken care of is relative to your exact length of service.  However, a good rule of thumb would be ten to twelve years as a typical lifespan. After that, the system starts to degrade and become less effective. Some components can be replaced along the way to keep you comfortable and your system efficient. Contact me for additional questions along this vein.

What are the benefits of upgrading to a high-efficiency HVAC system, and will it save me money in the long run?

The short answer is yes. Modern HVAC systems run at lower amperages, resulting in shorter KW Hour run times. This results in lower energy costs. A newer system will likely save you money in the long run. But ask our expert Abel to evaluate your system for his best recommendation.

How do I know if my system is the right size for my home or business, and what factors should be considered when sizing a new system?

To determine the proper size of equipment for a business or home, a load estimate should be made. During that procedure, the load estimate should consider the occupancy, the degree of insulation, the presence of windows and doors, etc.  I have over 20 years of experience and will give you my best recommendation on sizing.

What types of air filters should I use, and how often should I change them to maintain good indoor air quality?

I advise a MERV 8 rating at the very least.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers created the Minimum Efficiency Reporting Value (MERV) measurement scale in 1987 to provide more information than other evaluations about the efficacy of air filters.

How can I tell if my HVAC system is not working properly, and what are some common signs of issues that require professional attention?

The two most typical symptoms are inability to maintain the temperature set by the thermostat and a lack of cooling or heating in the region. Since we normally have a high humidity rate in the Houston area, we must compensate for this when sizing and operating HVAC systems.

What are the advantages of programmable or smart thermostats, and can they help me save on energy costs?

With the exception of smart thermostats that can be managed by WiFi and your mobile device, programmable and smart thermostats are nearly identical. Programmable thermostats allow you to schedule when they turn on and off or raise and lower the temperature. There are many factors to consider when changing or upgrading a thermostat, including placement, zones, how many floors, and the age of your system. Call us and we can provide an overall plan for implementation of a newer thermostat to best fit your system.

How do I choose the right HVAC contractor to perform installations, repairs, and maintenance, and what qualifications should I look for?

Every business must carry insurance, and a good, respectable contractor will be listed with the TDLR (Texas Department of Licensing and Regulation). Check out their website and reviews to see what people are saying about them. You can also research in Google or other social media for comments and reviews.
