 Has the Time Come for an AC Upgrade?

Monday, November 4th, 2019

top-view-outside-ac-unitThe calendar may be telling the world that fall is here but that means nothing to our state. Here in Tampa it often feels like summer is never-ending. Because of this, we are prone to rely heavily on our air conditioning systems to keep us from overheating on a regular basis.

With all this consistent use, however, our cooling systems see a lot of wear and tear. This takes its toll over time, of course, and there comes a day when no amount of maintenance or repairs will help. When that day comes and your AC system simply isn’t up to the job anymore, you may have to consider an upgrade.

If and when you are faced with this decision, we hope you know that the team at IERNA’s Heating & Cooling is available to help with your Tampa AC installation needs. Our professional technicians are ready and available to help with everything from selection to sizing and more.

Are You Using Your Cooling System As Efficiently As Possible?

Monday, September 24th, 2018

Woman feeling hot and trying to refresh in summertime heatThere aren’t many people in the Tampa area who would argue against you that having a fully effective air conditioning system is an absolute must. Not only is this needed to make your home comfortable, but to make it bearable. If your air conditioner doesn’t work the way it’s meant to, however, then you may need repairs, or it could even be time to look into a new Tampa AC installation, depending on how old your unit is.

These are not your only options when it comes to increasing system efficiency, though. You may have a brand new air conditioner that works just fine and has a high-efficiency rating already. That doesn’t mean you can’t improve the efficiency even more, though. And by improving the efficiency, you’re ultimately saving money! So, what’s the trick? Well, there are a few—read on!

Why Choose Ierna’s Heating & Cooling? Expertise and Customer Care!

Air Conditioning | Tampa | Ierna's Heating and Cooling

“We were fortunate enough to have the owner, Ron, work up a quotation for my home here in Tampa, for a 4 ton heat pump with variable speed handler. The breadth of services described was thorough and thoughtful, giving consideration to all the elements of the installation (beyond just a Manual J calculation). In addition to the individual components for replacement, the quotation explicitly stated all costs, parts, labor, and it was clear that no additional fees were hidden in the quote. Best of all, the quote included assurances on service and warranty on installation for the next 2 years–these assurances differentiated this company from five other competitors from whom we solicited quotes.

We ultimately selected Ierna’s given the good ratings on Angie’s List, the competitiveness of their quote, the years of experience, and the quality of the products offered. It’s worth mentioning that the price of the contract was the only one of the five that enabled us to recoup our expenses based on energy savings, within a 10 year period (which seems to be the life expectancy of these components here in FL).

Our system was installed last week and was completed within a single day. The associates who installed the system were professional and patient, taking efforts to minimize any mess as a result of tear out/installation, and left the place looking better than it was. In fact, the attic, where the handler was situated, was previously a mess of ducts and returns prior to installation and they revised the returns considerably to the effect of making it appear cleaner and more efficient, even to my untrained eye.

Especially appreciated was the high level of expertise of the team–it seemed to me that they were quite senior and their familiarity with each other, as well as their combined experience resulted in highly efficient execution of tasks.

In conclusion, I’m happy to report positive experiences all around and wouldn’t hesitate to recommend Ierna’s to family and friends.

AC Tip: Getting the Most Out of Your Ductless Mini Split System

Monday, August 27th, 2012

Ductless mini split systems are a great air conditioning and heating option.  Ierna’s Heating & Cooling is an air conditioning company in Wesley Chapel that can help you get the most out of your ductless mini split system.

In order to get the most out of your ductless mini split system, the first order of business is proper installation.  Installation includes the placement of an outdoor condenser unit and one or more separate indoor air handling units all connected through refrigerant and power lines.  Correct placement of both of these units will be essential in how efficiently the system cools and heats.

Proper care and maintenance of your ductless system will also be essential in keeping it operating at its highest efficiency, so that you can save in energy consumption costs while still staying comfortable indoors.

Some of the great benefits associated with using a ductless system include their high energy-efficiency, space savings, and increased climate control.

When you choose ductless AC, you are getting a high-efficiency air conditioning system that costs less to operate than a forced air system.  You will also enjoy saving space indoors with their compact design and out of the way placement. Ductless systems also offer great zone control: if someone likes it colder their room can be colder, if someone else likes it hotter, that zone can be set hotter.

Ierna’s Heating & Cooling has Wesley Chapel AC technicians that understand how to help you get the most out of your ductless system, all while providing friendly customer service and quality workmanship in every installation and maintenance that is completed. Call us today to learn more!

What’s Going On With R-22?

Thursday, August 2nd, 2012

R-22 Phaseout | Tampa | Ierna's Heating and CoolingRecent actions by the US Environmental Protection Agency (EPA) regarding HCFCs have led to uncertainty about the availability of R-22 in the coming months and years. In response, contractors have noticed a ramp-up in the chatter about R-22 and price changes as some manufacturers and importers have amended their sales policies.

This situation is the culmination of several factors, including the continued implementation of the federal government’s policies regarding HCFCs, current market conditions, and delays in the regulatory process.

As most contractors know, the EPA controls the production of HCFCs, including the refrigerant known as R-22, through allowances that limit how much each gas manufacturer and importer can produce or import in a given year. Under the implementation of the Montreal Protocol, the production and use of R-22 is slowly being phased out.

In August 2011, the EPA proposed to adjust the allocations in place for the years 2012-2014. This adjustment was necessary because of a lawsuit filed by two HCFC producers who had completed a legal trade of allocations that EPA had failed to recognize in its allocations released in 2009.

EPA consulted with industry stakeholders before proposing to reduce the annual allocations. In gathering information used to develop the August 2011 allocation adjustment, EPA found that there was an oversupply of R-22 in the marketplace, partly evident by a lack of demand, increased reuse of R-22, and low wholesale prices. In fact, in 2010, producers of R-22 only utilized 86% of their allocations. A trade organization representing the manufacturers and importers of R-22 supported these claims, and advocated for a 20% reduction in allocations for 2012-2014.

By the end of 2011, EPA had yet to finalize its adjustment proposal for the 2012-2014 allocations. But EPA did release a subsequent version of the August 2011 adjustment proposal on December 30, 2011, one that proposed to reduce the allocations for 2012-2014 between 11-47%.

Without a finalized adjustment rule, the producers and importers of R-22 were stuck in a legal limbo – on January 1, 2012, they did not have the authority to manufacture or import R-22.

Recognizing this problem, on January 20, 2012, EPA sent “non-enforcement” letters to the producers and importers of R-22, alerting them that they could resume the manufacture and import of R-22 in the interim even though EPA had yet to set the new allocation amounts. The non-enforcement letter advised that production would be curtailed by 45% of their last allocation amount, the high end of the allocation adjustment proposal.

It is expected that the EPA adjustment proposal will take at least until the summer of 2012 to be completed. The end result could be a reduction in R-22 allocations somewhere between 11-47%, meaning it is likely the final adjustment proposal will be less than the interim 45% reduction and that more R-22 may be produced or imported.

ACCA has been following this issue to provide contractors with the most up-to-date and precise information available. We will continue to monitor the allocation adjustment rulemaking process and alert members of any progress or actions taken by EPA.

The EPA has the following advice for homeowners and customers:

Alternatives to R-22 in Residential Air Conditioning

As R-22 is gradually phased out, non-ozone-depleting alternative refrigerants are being introduced. Under the Clean Air Act, EPA reviews alternatives to ozone-depleting substances to evaluate their effects on human health and the environment. EPA has reviewed several alternatives to R-22 for household and light commercial air conditioning and has compiled a list of substitutes that EPA has determined are acceptable. One of these substitutes is R-410A, a blend of hydrofluorocarbons (HFCs) that does not contribute to depletion of the ozone layer, but, like R-22, contributes to global warming. R-410A is manufactured and sold under various trade names, including GENETRON AZ-20®, SUVA 410A®, Forane® 410A, and Puron®. An additional refrigerant on the list of acceptable substitutes for R-22 in residential air conditioners and other products is R-407C. Residential air conditioners and heat pumps using R-407C are not available in the U.S., but are commonly found in Europe. EPA will continue to review new non-ozone-depleting refrigerants as they are developed.

Servicing existing units

Existing units using R-22 can continue to be serviced with R-22. There is no EPA requirement to change or convert R-22 units for use with a non-ozone-depleting substitute refrigerant. Such changes, called “retrofits,” are allowed if the alternative has been found acceptable for that type of use. R-407C is allowed for retrofits but R-410A is not allowed in retrofits due to its higher working pressures. In addition, the new substitute refrigerants would not work well without making some changes to system components. As a result, service technicians who repair leaks to the system will most often continue to charge R-22 into the system as part of that repair.

Installing new units

The transition away from ozone-depleting R-22 to systems that rely on replacement refrigerants like R-410A has required redesign of heat pump and air conditioning systems. New systems incorporate compressors and other components specifically designed for use with specific replacement refrigerants. For instance, if a new outdoor unit (typically called a “condensing unit,” containing the condenser and compressor) is installed, it is likely that a new indoor unit (typically called an “evaporator”) will also be required. With these significant product and production process changes, testing and training must also change. Consumers should be aware that dealers of systems that use substitute refrigerants should be schooled in installation and service techniques required for use of that substitute refrigerant.”
