What are MERV filters and can I get one?

A Merv Filter is a furnace filter. The letters stand for Minimum Efficiency Reporting Value. The higher the MERV value is, the more efficient the filter will be in trapping airborne particles. MERV values range from one to 20.  Home air filters are usually rated between five and 13. Isaac does install MERV 13 filters. Filters can be purchased from Isaac and picked up at our branches. They are also available at neighborhood stores and online retailers.

The upstairs of my home is warmer than the rest of the house when the air conditioning is running. What can I do?

To evaluate the cause of this, you would want to schedule an estimate for a zoning quote. This estimate will evaluate your home for possible problems that are causing the varied temperatures throughout your home.

Isaac can also balance your heating and air conditioning systems using your dampers on the supply runs — if that is a possible option.

I had someone come out and give me a quote, when will they be getting back to me with a price?

The timing on this depends on the complexity of the quote and if you are anticipating using a loan vendor. Your Isaac Project Manager should have a proposal ready during the initial quote appointment. Sometimes, if loan approvals are involved or if the job is more complex, it could take approximately one to three days on average to receive a final price.

You can always reach out to your Project Manager with any questions. They will be more than happy to answer any questions along the way.

When will I get my rebate check?

The timing on your rebate check depends on the type of rebate you are expecting.

For a manufacturer rebate, such as Lennox, Rheem, etc., this is handled internally by the office staff at Isaac and takes about four to six weeks from the installation date.
