Mike Merritt Heating & Air FAQ

View the Mike Merritt Heating & Air FAQ below to learn the answers to many of our most commonly asked questions. Getting comprehensive HVAC information shouldn't be hard, so we're always happy to answer any questions.

What is the SEER rating?

The SEER (seasonal energy efficiency ratio) rating is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER, the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 17.

What should you, as a prospective customer, look for when selecting a heating and cooling system for your home?

Quality, Performance, and Reliability are extremely important. I would like to offer the following suggestions:

  • Quality Installations
  • Reliable Equipment
  • Purchasing The Equipment With The Highest Seer and HSPF Possible, While Staying Within Your Budget This Will Reflect A Lower Energy Bill
  • Selecting A Brand Of Equipment Which Offers The Best Standard Warranty

Installation is just as important as the product line. Getting a Quality Product at a fair price is important. However, workmanship and having confidence in your vendor is just as important.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is derived based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the total rating.

Why should I have regular (or preventative) maintenance? And how often should I have it performed?

Your heating and cooling systems work incredibly hard to perform their functions for your home every day. The constant stopping, starting, and continual operation can wear down any machine if the proper care and maintenance are delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires, and corroded electrical contacts that the naked eye may not notice. You should have maintenance done on your system regularly to ensure maximum efficiency and to prevent other problems from occurring.

I need help troubleshooting a problem with my equipment.

Mike Merritt Heating & Air is your troubleshooting expert. In addition, the manufacturers also provide a network of troubleshooting technicians at their distribution centers across the country, which Mike Merritt Heating & Air will utilize to solve your concern. Should we encounter a situation that requires additional factory help, we will contact our factory supported Service Manager(s) for assistance.

What equipment requires regular (or preventative) maintenance?

At least once a year, heat pumps and air conditioners require a professional tune-up. Because gas-fired equipment functions with greater efficiency, they only need to be serviced every other year. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, line kits, and refrigerant lines.

What are the advantages of a programmable thermostat?

Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats, you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

What Type of Filter Should I use? How Often Should I replace it?

Standard filters work to keep your system and its ductwork clean, but they don't really improve indoor air quality. To do that, you need a media filter. The media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal by seven times that of a standard filter. However, upgrading to a pleated media filter will remove everything from insecticide dust to airborne viruses from the air. Always choose a filter that matches your blower's capacity. For optimum efficiency and filtration, Mike Merritt Heating & Air recommends that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

Where can I get parts for my equipment?

Mike Merritt Heating & Air can identify and supply the correct, current parts for your system, as well as pricing and availability.

Which equipment will best fit my home?

Many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. Mike Merritt Heating & Air can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family's needs. Depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to ensure the size of the system you purchase will be large enough to cool your home, but not any larger than you need, is to have your home's individual heating and cooling needs evaluated by a licensed professional.

What does my warranty cover?

Under the standard factory warranty, Carrier and Comfortmaker cover parts that fail during the warranty period due to defects in the parts. The warranty does not cover labor. A warranty certificate was included with your homeowner information packet and is specific to the model numbers, serial numbers, and installation dates of your products. If you cannot find your warranty certificate, Mike Merritt Heating & Air will also be able to provide you with the information.

What is the life expectancy of my unit?

Dependable Carrier and Comfortmaker products are among the longest lasting heating and cooling products available. For your specific equipment, many variables affect life expectancy, including the regularity of routine maintenance.
