Frequently asked questions

When we talk about refrigerant we are typically referring to R-22, up and until January 2010 it was the refrigerant that came in all equipment, it had been around for 50 years and even though it was supposed to go through a phase out (chlorine properties, ozone stripping) builders and manufacturers installed it right up to the last date. At NASCAIR we invest and plan long term, we started installing R-410 systems in 2005, it was more expensive, supposedly temperamental, not forgiving and installation practices had to be sterile. We nailed it, we have very few of our customers beholden to R-22 therefore if they need a little refrigerant its negligible cost. As of Jan 2015 there is no more production of R-22 allowed under multinational environmental agreements, Montreal Protocol and the Kyoto agreement.

There are only about 8 mainstream manufactures left, there may be thirty brand names but those are just decals, I have had experience with every one of them, 22 years of repairing, getting tech support, filing warranties, dealing with defects, holding manufacturers accountable and holding home owners accountable.

Here is what you should look for: A very good, well trained responsive HVAC company, remember what I said there are only 8 manufacturers, yes equipment is important, I love both my AMANA brand and TRANE brands, but they each fill different needs for me and the consumer, Trane has a long history of dependable, innovative equipment and it has a reputation and a name that people want to pay for.

This is possibly the most common question we are asked, and there are several factors that can persuade the decision either way. Some of the things to consider are the age of the equipment, the repair history of the system, the reliability of the manufacturer and what refrigerant your system uses.

Answers: As your system approaches that 12 year mark be cautious on repairs especially if it has to do with adding refrigerant or leaks. If your system has been well maintained and does not have a history of adding refrigerant by all means consider repairs less than $750. Some manufacturers have better track records than others, there are certain brands that make me roll my eyes when I walk up on them because I know the outcome.

The big one, if your system uses R-22 the old refrigerant and its leaking I won’t repair it, it is a liability to you and me. Current cost for a 30lb cylinder of R-22 is $700, don’t do it.

Many factors go into determining the size of the system. Including type of house and walls, type and size of windows, insulation, basement and attic conditions, house orientation, and so on. A comfort consultant must visit the house and take detailed measurements. With these measurements the comfort consultant can perform a performance load calculation in order to assure proper system size.

A system that is too large will cool or heat your house quickly, but you may not feel comfortable. That’s because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air during the cooling mode, leaving you feeling sticky and humid. This could even lead to moisture and mold problems. And, the stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills.

On the other hand, a system that is too small just cannot get the job done, especially in extreme weather conditions. The air conditioner will run constantly in the summer and the furnace will do the same in winter. But a correctly sized system isn’t just based on the size of the structure.
