Westwood Heat Pump Question: What Size Heat Pump Is Right for My Home?

Monday, August 27th, 2012

One of the most important questions to answer when purchasing and installing any new heating or cooling system in Westwood, no matter what type, is what size is best for your home. You need something that has enough capacity to heat or cool your whole home comfortably; otherwise your house will consistently be at an undesirable temperature.

Some people might think that the quickest solution to this problem is to just buy a system that they are sure has a capacity larger than the size of their home. You may even be tempted to get the biggest model out there, under the logic that the biggest is the best and it will be sure to be able to cover your whole house.

While this line of thinking might make sense to you, it’s actually not a good idea. The problem with this “solution” is that you can wind up with a heat pump that is considerably too large for your needs, which means your home will consistently be either too cool or too hot, and your energy bills will be unnecessarily high.

The best way to choose a new heat pump is to have a professional do a load calculation in your home. This can be a highly technical process, so it is best to leave it to the pros. However, here are some quick tips and other things to consider on the subject:

  • There are a lot of variable to consider in doing a calculation like this. A contractor doing a load calculation will consider the type of construction, what kind of insulation you have installed, what kind of windows you have, whether there is an attic, how many people live there and many more factors.
  • Also, since heat pumps are used for both heating and cooling, different contractors may opt to do the calculation in different ways. Some will estimate capacity based on heating, while others will base it on cooling. Ask to see which is the case for any estimate you receive.
  • If you are getting a new heat pump as a replacement for an existing one, or even a different heating/cooling system, check the capacity of the unit you are replacing. That can be a good place to start. You will at least be in the right ballpark.

All of this means doing some extra leg work up front, but getting the proper sized heat pump for your Westwood home is well worth the effort. Call DB Heating & Cooling today to learn more about heat pump installation!

Waldwick AC Repair Guide: Icing Problems on Air Conditioner Cooling Coils

Monday, August 20th, 2012

Air conditioning cooling coil icing problems can arise for a couple of reasons: either the air filter has not been properly replaced, or there is a condensing coil leak.  It is best to check and test the easiest problem first and then move on from there.

It is important to replace your Waldwick air conditioner’s filters as often as is recommended by the manufacturer.  A common result of not replacing filters frequently enough is a buildup of dust and dirt on the filter, which causes reduced air flow throughout the air conditioning unit.  With reduced air flow, the evaporator coil or cooling coil within the air handler can become blocked by ice or frost build-up.  Having cooling coil icing can significantly reduce or completely stop the amount of cool air being produced by an air conditioning unit.

Easy steps to diagnose and resolve air conditioning cooling coil icing problems:

  • Visually inspect the air conditioning cooling coils to check whether reduced air flow has been caused by cooling coil icing.  If ice or frost is found on the coils, thus blocking air-flow, proceed with the next step.
  • Turn off the air conditioning system completely to allow ice to evaporate, the unit will have to remain off until all ice is completely melted and drained away from the unit
  • Replace all dirty filters on the air conditioning unit
  • Once the a/c unit is de-iced and has fresh filters, it is safe to turn the system back on, to test whether the icy build-up happens again

If after completing these steps, when the air conditioning unit is turned back on cooling coil icing happens again, this could mean one of two things.  Either too little of the refrigerant is being released into the cooling coil due to a clogged capillary tube or a stuck thermostatic expansion valve.  Or the refrigerant charge is too low due to a refrigerant leak.  A refrigerant leak can happen at any point in the refrigerant piping system which would then need to be soldered and resealed, or it can happen in the cooling coil or condensing coil which could mean the entire coil needs to be replaced.  Fixing of refrigerant leaks should be handled by a Waldwick air conditioning professional.  Contact an experienced HVAC technician at DB Heating & Cooling that can identify the air conditioner cooling coil icing problem and execute the proper solution.

Programmable Thermostats and Your Paramus AC

Monday, August 13th, 2012

Air conditioning makes our Paramus homes comfortable during a hot summer day. However, air conditioners need electricity to run, and most of us are trying to reduce our home’s energy consumption. There are a number of ways you can make your air conditioning system more efficient, including upgrading to an ENERGY STAR rated unit and scheduling regular maintenance, but one of the easiest steps to implement is installing a programmable thermostat.

Programmable thermostats automatically adjust the temperature in your home depending on the time of day. You can save up to 10 percent a year by turning down your thermostat back ten degrees for eight hours a day! Most models allow you to store multiple daily settings, so you can turn you air conditioner down during the day when you are at work and while you are sleeping, and still have the temperature cooler when you need it. You can also still manually adjust the temperature without affecting the normal settings, giving you complete control and helping you save energy.

Programmable thermostats are not all made the same, and there are many different makes and models. An Paramus HVAC contractor will go over the different features available to you so you can decide which best fits your needs. Different thermostats work better with different systems, for instance some heat pumps need thermostats that have multi-stage functions, so it is best to consult with a professional before deciding what to purchase.

Programmable thermostats allow you to save energy without sacrificing comfort, which is something that all of us are looking for. If you are looking for a simple, affordable way to improve your Paramus HVAC system, a programmable thermostat is a great choice. Most are easy to read and easy to use, call DB Heating & Cooling Inc today to learn more about having a programmable thermostat installed in your home!
