HVAC Preventive Maintenance

Advantages of HVAC Preventive Maintenance

Heating and cooling systems are among the most important things to maintain in your home.  These systems keep your home comfortable in all seasons.  There is nothing worse than coming home to find that the HVAC system has failed in the middle of winter or during a heat wave in July.  Regular system maintenance is critical to keeping everything in proper working order.  Here are some advantages to scheduling preventive maintenance for your HVAC system.

Fewer repairs– Regular maintenance allows technicians to catch small problems before they become a major expensive repair.  This can save the homeowner money in the long run.

System Longevity– Maintaining the HVAC system can increase its lifespan.  A unit that is regularly serviced and cleaned will run as it should with fewer break downs.  Just as your vehicle will run longer with regular maintenance, so will your HVAC system.

Lower Energy Bills– Systems that are not well maintained don’t run as efficiently as they should.  This can result in higher utility bills for the homeowner.

Better Air Quality– An HVAC system that is regularly cleaned and maintained will provide better air quality in your home.  Regular maintenance includes changing the air filters.

Regular HVAC preventive maintenance can pay for itself by preventing future repairs or expensive break downs.  There are many things the average homeowner is not trained to do.  An experienced HVAC technician will perform a thorough inspection of the system and all its components.  The technician will lubricate moving parts, check the condensation drain, check and repair any leaks in the system, check the system controls and thermostat, and clean the blower, evaporator, and condenser coils.  Having a preventive maintenance relationship with an HVAC company may offer other benefits to the homeowner, such as discounts on repairs and priority service scheduling when there is a problem.

At B Tucker Heating & Air we recommend having your HVAC serviced at least twice a year for best results and system longevity.  Call us today to learn about our Preventative Maintenance.

Choosing the Best Air Filter

Air filters are designed to protect the blower fan and the evaporator coil in your furnace or heat pump fan-coil by removing particulates from the air as it is passes through the system. These filters are made of porous membranes that allow air to pass through but trap particles of dust, dirt, pollen, pet dander, and other pollutants. The accumulation of these particles on the filter or evaporator coil reduces air flow and decreases the efficiency of the HVAC system. Changing filters regularly improves indoor air quality, extends the life of the system and reduces energy cost.

In the average family home, filters should be monitored at least every 90 days. Filters in homes with pets should be monitored more frequently. Most service companies have maintenance programs that call for two visits a year. Technicians should make the customer aware of how often filters should be changed and instruct the homeowner how to do it themselves, if it is necessary to the proper operation of their systems.

Filters are rated using the “minimum efficiency reporting value” or MERV rating system.  There are several different types of filters:

Fiberglass/synthetic filters – These flat panel disposable filters are the most common type and are the least efficient. They are inexpensive and catch only larger particles moving through the system. They do not remove harmful contaminates or improve air quality. Their MERV rating is very low, usually in the low single digits.

Polyester and pleated filters – These filters are a slight bit more expensive that fiberglass filters but are better quality and longer lasting. Pleats increase surface area, which catches more airborne particles. The polyester material is also less porous and is a better choice for people with allergies or asthma. MERV rating for these devices generally touch on the lower double digits.

Electrostatic filters – This type of filter has self-charging fibers that attract and trap particles from the air. Two types are available – disposable and a type that is washable. Disposable ones should be changed regularly, just like the previously mentioned filters, about every 6 months. Washable ones should be cleaned regularly and dried completely before reinstalling. The washable ones can last between 1 and 4 years with proper maintenance. MERV rating for these devices range into the mid double digits.

HEPA filters –  Most residential systems cannot accommodate HEPA filters. They are more commonly used in hospitals and commercial systems. They are very high efficient, trapping the most harmful particles. These devices do, however, decrease the efficiency of the central systems to which they are attached. MERV ratings for these devices are at the top the scale.

A Spring Tune-up Prepares Your HVAC System for Warm Weather

Before you’ll need to run the air conditioning full time during the summer, schedule a tune-up for the HVAC system.  Spring is the perfect time to prepare the system for warm weather.  Keeping the HVAC system properly maintained can save homeowners time and money in the long run by extending the life of the system.  A qualified technician should inspect and clean the unit.  It’s generally easier to book an appointment with an HVAC company during the spring, before the weather gets too hot.  Here are some seasonal maintenance items that should be performed.

Change filters- Filters that have been used all winter are dirty and should be discarded.  Clogged filters reduce air flow and cause the system to run longer than necessary.  Clean filters improve air quality in the home by removing dust and allergens from the air.  Organic material that accumulates in the unit can cause mold to grow.  HEPA filters may be appropriate if family members have allergies or respiratory problems.

Check air unit– The air conditioning unit hasn’t been used all winter, so a technician will ensure the unit is cooling properly.  The condensation lines and drains should be inspected and cleaned.  Moving parts should be lubricated.  The thermostat should be examined to ensure it is properly calibrated.

Inspect outdoor unit– The outdoor unit should be inspected and cleaned.  Debris should be removed from the coils.  The outdoor fan should run smoothly.  The refrigerant lines should be inspected, and the coolant level evaluated.

Adjust humidifier– If the home has a furnace mounted humidifier, it should be turned all the way down or off.  Spring is a good time to clean and make repairs to the humidifier so that it will be in proper working order next winter.

Properly maintaining your HVAC system in the spring can help homeowners avoid costly repairs.

Make your basement

How to make your basement build-out comfortable

I have done several proposals lately for people who are finishing an unfinished basement. They are always shocked to find their existing equipment isn’t large enough to do the job. Or if it is large enough, they can’t simply tap into the duct work handling the floor above to heat and cool their lovely new space. Many times these “do-it-yourselfers” head out to Home Depot, purchase a few hundred dollars-worth of miscellaneous flexible duct work, boots, elbows and grills, head back home and waste an enormous amount of time and money, only to discover they not only do not have the proper tools, they do not understand the simple concepts of how to use them once they acquire them.
