Wine Cellar Cooling in Dry Climates

Could the precious wines in your collection be going up in smoke? Many people overlook the essential role humidity plays in the wine cellars In dry climates, this overlooked wine storage factor can quickly result in the loss of wine through evaporation.

Why Are Humidity Levels So Important?
There’s more to wine storage than merely keeping things cool. When wine is bottled after fermentation and sealed with natural cork, moisture is essential to maintaining a tight seal. In dry, hot environments, cork can shrink, compromising its seal to allow for oxygen exposure and resulting in off-flavors and aromas, and ultimately, spoiled wine. Humidity control in your wine cellar is therefore essential to preventing this disastrous occurrence from effecting your entire collection.

Your Wine Cellar Cooling Unit Is Not Enough
Many wine aficionados mistakenly assume their carefully constructed cellar confines, combined with their wine cellar cooling systems, are enough to maintain the environment essential to preserving the premium flavors of their coveted collection. Unfortunately, a cooling unit alone cannot add moisture or humidify wine cellar air. Worse, cooling units also have the tendency to exacerbate this problem, removing humidity from the air as part of normal operation. An integrated humidifier is necessary to ensure the optimal level of relative humidity (RH) for wine – ideally around 60 to 70% RH.

Do I Need a Humidifier in My Wine Cellar?
For those that care about the quality of their collection, wine cellar humidity control and temperature must both be addressed. If you live in a dry region of the U.S., the addition of a wine cellar humidifier is indeed necessary. This is especially essential to preventing spoilage in hot, dry climates.

What to Look for in a Wine Cellar Humidifier
(Built-in) Wine cellar humidifiers distribute moisture evenly in the air circulated by your cooling unit. To ensure adequate protection and optimal performance, look for options with…

• Adequate Capacity
  Your humidifier must be sized specifically to the dimensions of your wine cellar, taking into account its construction, bottle capacity, and other storage characteristics. A humidifier with a capacity rated at the temperature of the wine cellar (not room temperature or discharge temperature) is highly recommended.
• Precise Control
  To ensure stable humidity levels, an automatic humidifier, set to self-regulate moisture levels, is ideal.
• Durable Construction
  Your chosen humidifier should be rust and corrosion proof, given the ideal humid wine cellar environment.
• Ease of Maintenance
  Avoid options that require manual filling, which could lead your humidifier – and corks – to run dry. Units with built-in drains and automatic flushing likewise reduce maintenance needs, with superior systems requiring only annual or biannual maintenance.
• Safe Operation
  ‘Wetted pad’ designs releases humidity via vapor, eliminating the introduction of bacteria and dust into the air of your cellar.

Year-Round Allergy Symptoms? Fight Back with Our Complete Indoor Allergy Guide

A Complete Guide to fighting Indoor Allergies

Your indoor environment could be the source of an abundance of allergy and asthma triggers, according to the EPA. Do you know what dangers are lurking in your home – and how to reduce your exposure? Knowledge is key to successful asthma and allergy management.

What are Indoor Allergies?

Extremely common, allergies effect an estimated 50 million Americans. And indoor allergies can be hard to pinpoint, because symptoms are often confused with the common cold. Drippy nose, itchy eyes, congestion and wheezing with symptoms that linger for weeks on end are prime indicators. What differentiates this from a cold? Fever, chills, body aches, and yellow/green nasal discharge that clears after a week or two.

What are the Most Common Indoor Allergens?

• Dust Mites
  A common trigger of allergy and asthma symptoms, dust mites are everywhere, consuming human skin flakes and thriving in warm, humid environments like bedding, upholstery and carpeting. Their body remnants and droppings cause a great deal of allergy woes.
• Cockroaches
  Roaches can be found anywhere, and are a big problem in inner-city environments – even in homes that aren’t dirty. The protein in their droppings is a common allergen.
• Pollen
  A variety of pollen can easily be carried into your home on shoes, clothing, and animals. Plants in the home can also produce pollen allergens.
• Mold
  Mold thrives in damp areas (bath, basement, kitchen, laundry). Mold releases tiny, allergen-inducing spores, and in some varieties, potent mycotoxins capable of causing severe reactions/sickness in sensitive individuals.
• Pets
  Because people are allergic to saliva, dander (dead skin flakes) and urine, there are no truly “hypoallergenic” breeds.

How Can I Reduce Indoor Allergies?

Avoiding allergens – or reducing exposure – is the most effective remedy.

• General Cleaning
  • Where a dust mask when you clean.
  • Opt for hard flooring and non-porous, easily washable surfaces, like leather.
  • Dust, and vacuum often with a HEPA filter.
  • Address water/moisture issues promptly (mold, mites, roaches).
  • Use your air conditioner to keep humidity low to guard against mold and dust mites. Dehumidifiers and exhaust fans are also helpful.
  • Change allergy-laden filters often.
  • Talk to your HVAC pro about upgrading to a high efficiency disposable pleated filter with a MERV 8-12, and system compatibility.
  • Clean and disinfect bathrooms, kitchens and basements regularly.
  • Don’t neglect carpet and upholstery. If it can’t be laundered, clean it with products that deactivate/denature dust mites/dander.
• Allergen Specific
  • Dust Mites
    Use allergen-proof fabric covers on mattresses, pillows and box springs. Wash bedding weekly in hot water (130° F) and dry on high heat. Place stuffed animals and a freezer bag, and freeze for 2-4 hours weekly.
  • Cockroaches
    Clean countertop crumbs and dishes regularly, empty the trash, and store food in tightly sealed, hard-sided containers. Contact pest management ASAP for infestations.
  • Pollen
    Leave shoes outside. Shed outerwear, before entry, for the wash. Shower if symptoms persist. Enjoy plants outdoors – leaving them out of the house if allergic.
  • Mold
    Properly ventilate moisture-prone areas via window or exhaust fan, employing a dehumidifier when necessary. Mold loves carpeting – avoid it in these areas.
  • Pets
    Wash hands after petting. Keep pets out of the bedroom, other areas where you spend a lot of time, and keep them outdoors when possible. Ask a non-allergic family member to clean pets weekly, as well as their habitats/belongings.

Do Air Purifiers Really Work for Allergies?

Air purifiers with HEPA filtration with MERV ratings of 17-19 are capable of trapping and removing 99.97-99.999% of particles 0.3 micron and larger from the air, including dust, mold, pollen, viruses, bacteria, and odors. UV light versions further reduce the likelihood of air pollutants, killing bacteria, germs and mold. To ensure a reduction of asthma and allergy symptoms, look for true HEPA filters and systems, not those labeled “HEPA-type” which don’t meet stringent standards. As with all air filters, changing them as recommended is key to preventing the redistribution of allergens throughout the home. Be aware, HEPA filters are not designed to work with residential HVAC systems without modification, and could result in system damage. Before installing a filter with a rating higher than MERV 8, consult your friendly neighborhood air conditioning technician.

How to Spot a Bad Contractor!!!

Rushing through the selection of a contractor for your upcoming air conditioning installation or other home renovation project? Skipping-out on the ‘research’ portion could cost you. While there are many trustworthy contractors out there, sadly there are also quite a few trying to take your money and run.

Watch Out for these Red Flags to Avoid Construction Nightmares:

1. High Initial Down Payment
   With materials to source and workers to hire, a down payment towards your new air conditioning installation can be expected. Pennsylvania HIC (Home Improvement Contractor) licensing regulations require contractors collect 50% down payment for custom orders before a job starts – but not 100% down. Any request for more than 50% payment up-front should set-off alarm bells.
2. Cash-Only Requirements
   The need to be paid in cash only is a sure sign of shady inclinations. The ability to use check or credit card payment gives you infinitely more options should disputes arise. Without such supporting documentation, it’s your word versus the contractor on what was paid.
3. Lack of References
   If you can’t reach contractor references (or worse, the contractor won’t give you any), something is off. Even if a contractors claims to be just starting out, pass for someone with more experience. After all, your home is your biggest investment. If you’re just beginning your contractor search, try working backwards: Try asking close friends or family who they recommend. Word-of-mouth referrals are generally best. Online reviews are also a good resource – albeit not always 100% reliable.
4. No License & Insurance
   Even in an emergency, ask to see license and insurance documents before work begins, which are required-by-law in most areas. Preferably license and insurance information should be posted on proposals, business cards, and vehicles. All contractors must be licensed and insured to work on your home – otherwise you could end up liable in the event of accident or damages to neighboring property.
5. Permits
   If the contractor is telling you that it is not necessary to apply for permits, beware! In fact most city’s, townships and boroughs require permits and part of the process is to check the contractor’s insurance.
6. Lack of ‘Back-Up’
   Any professional contractor you hire to work on your home or HVAC system should have a physical address (not work out of a truck), giving you the ability to track them down if things go wrong. They should likewise back-up their skills with professional affiliations and certifications, such as NATE or EPA, alongside warranties on work and equipment – which should be years – not months – so that you get what you pay for.
7. Handshake-Only Agreements
   Detailed, written contracts ensure you get what you pay for – and everyone is on the same page. Make sure contracts include cost estimates, specific materials used (to thwart bargain substitutions), and completion timetables.
8. Subcontractor Parade
   Good contractors do outsource specialty work – like tricky electrical. However a multitude of subcontractors parading through your home should set-off warning bells. Who are you letting into your home? Are they likewise licensed, drug and background checked?

Looking for an HVAC contractor who has your best interests at heart? Count on the friendly service of your local H&H Heating & Air technician. When it comes to trusted service, we check all the boxes. Contact us for a trustworthy quote and complimentary referral list today.

7 Signs Your Air Conditioner needs Repair

The weather is warming up… And you’re not 100% sure, you think your air conditioning system may not be performing quite the same as it did last year. Is it time for a maintenance call to an HVAC company? Or are you overlooking something simple that may be leading to its performance decline?

7 Warning Signs Your Air Conditioner Needs Repair:

1. Air is not blowing cold.
   If air being circulated through your vents isn’t as cold as it used to be – your system is working overtime to keep temperatures comfortable. This could result from an array of possible causes, including leaking/low refrigerant, condenser issues, and duct leakage.
2. Air flow is poor.
   Your fan, which is responsible for pushing all that lovely, cool air through the ductwork, can succumb to a number of issues that can dramatically reduce airflow, ranging from dirty air filter, bad blower motor or faulty fan control board.
3. Moisture/water accumulation in strange places.
   Your system is designed to remain dry at all times, otherwise mold and mildew in your system and home could result. If you notice a leak, the system may be suffering a blocked or broken condensate drain, and fast attention is in your best interest.
4. Bizarre sounds.
   All systems are designed to run quietly. Louder than normal operation – especially metallic screeching, grinding or banging noises – indicate something wrong inside the unit (broken components, loose belts, debris). When strange sounds occur, you may need to get it checked by an air conditioning company so call the repairman ASAP to avoid significant system damage.
5. Funky smells.
   Funky smells can arise from an array of issues, ranging from pest infiltration to burned-out wire insulation and mold growth within. Tend to these quickly to protect your family’s health.
6. Thermostat issues.
   Sometimes your system is not the problem – it’s your thermostat. Some signs might be obvious (a setting of 75 and a home temperature that’s off by 10s of degrees), while others won’t be (varied temperature zones throughout the home). Luckily your knowledgeable area HVAC technician can rule this out in a jiff.
7. High cooling bills.
   Your air conditioner is the largest consumer of energy in the home. If it was operating fine last season, but this year’s energy bills have spiked, that’s a good indication you need your system looked over.

This Commonly Neglected Homeowner Maintenance Can Cause Many Problems
Short cycling, poor airflow, odors, freezing up, uneven cooling, and higher than normal utility bills can also be attributable to simple maintenance that takes the average homeowner less than 5 minutes to tend to: Air filter replacement. Unless otherwise indicated by your heating and cooling professional, this should be performed at a minimum of every 3 months – and far more often if you have children and pets. Don’t neglect this before reaching out to the repairman – it can also help you avoid getting a red face when he pulls that nasty old filter out of the system.

Don’t let your summer air conditioner repair needs snowball into costly emergency repair. Contact H&H Heating and Air Conditioning and schedule an air conditioner service and performance check today.

What does Nate Certified mean for HVAC?

As a homeowner, you’ll likely suffer the nail biting experience of selecting a heating and air conditioning service and repair company to tend to one of the most expensive appliances in your home. And many of the companies you’ll peruse will tout ‘NATE certification’ online (or on their apparel). Sounds like a good thing, right? But do you really know what it means?

What is “NATE”?
NATE is the North American Technician Excellence (NATE), the nation’s largest non-profit certification organization for HVAC (heating, ventilation, and air conditioning) technicians. Founded in 1997, it is nationally recognized and respected as the largest, most popular, and widely attained certification in the industry. NATE certification is not legally required to become an HVAC technician, but membership has its benefits…

What Are you Getting with a NATE Certified Tech?

NATE certification applies to individual technicians – NOT the HVAC service company. Technicians who earn NATE certification must pass a knowledge-based exam that identifies their real-world, working knowledge of HVAC systems. Developed and supported by industry professionals, the test and subsequent certifications were created to bring professionalism and high quality standards to the industry, as well as make it easier for consumers to identify quality HVAC service professionals. This means in choosing a NATE certified technician, you’re ensuring the best installation or air conditioning maintenance service available, better system performance and efficiency, and enhanced system lifespan.

How is NATE Certification Achieved?
NATE certification is no easy task. Because of their rigorous nature, a minimum of one-year work experience is recommended before attempting NATE certification tests. Tests include not only core knowledge ranging from basic construction, electrical, and scientific knowledge, but also include tool and safety essentials, as well as testing on how to achieve desired interior home comfort conditions. In addition to these core tests, technicians then choose to earn ‘Installation’ and/or ‘Service’ certification in an array of specialty areas ranging from air conditioning installation, distribution, and service to oil and gas heating installation and service. Some technicians (most of whom have at least five years’ experience) may also choose to earn ‘Senior Level Technician’ status, encompassing two specialty areas of certification, alongside a highly-challenging HVAC analyst efficiency exam.

NATE Certification Doesn’t Last Forever
Tests must be periodically retaken, and minimum continuing education requirements met each two years in order to maintain certification. This is to ensure certified technicians remain up-to-date on the latest in HVAC technology and industry knowledge, and ensure reliable HVAC service for consumers. If all technicians who represent a company are NATE certified, you can rest assured that company highly values the proven knowledge and skill of its workforce, and you’ll be receiving the highest quality service available.

Not All Technicians May Be NATE Certified
HVAC companies can advertise NATE with just 50% of technicians bearing certifications – so be certain to stipulate your desire for a NATE certified pro for your equipment.

You have a lot invested in your HVAC system. Protect it with the help of the friendly, trustworthy, knowledgeable, and 100% NATE certified staff of H&H Heating & Air Conditioning. Contact us for superior service today.
