The Problems with Installing the Heat Pump in the Attic

Here are some top reasons not to install an HVAC system in your attic space.

If you have considered it, counter-check these factors before booking a heat pump installation service with your local HVAC technician.

It is Complicated to Clean the Ductwork

The type of ductwork put in the attic is typically lightweight and flexible. They are made of light-duty plastic and sometimes canvas.

Cleaning them is tricky; you cannot perform heavy-duty cleaning that involves poking and vacuuming.

When your attic ductwork is covered in filth and mold, the only best way out is to replace them. Think of this con twice before getting an attic heat pump. And learn how to repair AC Ducts in attic.

Reduced Efficiency

It is no secret that installing your heat pump in the attic lowers its efficiency.

This means that you may have to pay more energy bills than when you had it on lower levels of the house.

You are probably wondering why installing the heat pump in the attic offsets its efficiency…

Your attic is typically 20-50 degrees hotter than the ambient temperature during summer. In winter, the attic temperatures may drop as much as the outside temperature. This hotter or colder attic climate makes the heat pump work extra to compensate.

In most cases, you may even need an extensive system to cover these differences. These attic temperatures will inflate your energy bills.

Also, many times,  the attic is an unconditioned space. A simple air leak would significantly affect the house’s energy efficiency.

Here at HVAC Santa Clarita, we are passionate about ensuring every home is highly energy efficient. If you suspect your system is no longer efficient, feel free to contact us. 

Rodent Infestation

During winter, everywhere is too cold for rodents. When they come across the warm ductwork in the attic, they will chew it and try to build their nests inside. First, this is severe destruction of the ductwork, and you will soon be battling serious air leaks.

With the holes in the ductwork, condensation and moisture will leak down to your ceiling, gradually destroying it.

Also, with rodents inside your ductwork, you will have to deal with harmful things such as the rodents’ feces.

 In such cases, depending on how big the damage is, you can perform a seal or get new ductwork installation services.

Problems Easily Go Undetected

If you have a heat pump in the attic (and the same goes to attic ac unit) you will likely forget routine maintenance until something goes wrong.

When it is hidden in the corner of the attic, people forget about simple things such as cleaning the air filters and the condensate drain. They only remember that they should take care of the unit when it no longer blows warm or cool air as needed.

Remember that ductwork naturally expands depending on the temperatures in and out of it. Over time, this expansion can loosen duct seals. This issue can result in massive yet subtle air leaks, mainly if you do not perform routine check-ups.

You May Have to Wait Longer for Heat Pump Repairs

Attics can get as hot as 150 degrees Fahrenheit in summer! Now, there is no way an HVAC contractor will go up there to fix the HVAC system in an unconditioned attic.

You will have to wait for the temperatures to lower before they can repair your system.

Sometimes, as we have stated, people remember their attic HVAC unit when something goes wrong. In such cases, you need an emergency HVAC repairs but will still have to wait for the temperatures to drop to get a technician’s service.

Drafts and More Dust Issues

During house construction, a vapor barrier is installed before the drywall insulation. This film prevents penetration of dust, air leaks and moisture.

However, when an air conditioner or a heat pump is installed in the attic, holes are made in the vapor barrier to penetrate vents that supply air to all the rooms.

When these holes are drilled, sometimes they are not re-sealed perfectly. For starters, this results in heat and draft loss during winter.

Secondly, this issue will introduce a lot of dust into the living space.

If you already have a heat pump in your attic or an attic furnace, you may want to ensure that the drill through the vapor barrier is well sealed. Follow these simple steps to check:

  • Take the ceiling grill off, then look between the drywall and the vent pipe that goes down.
  • Look for plastic tape or sealant installed around the vent pipes,
  • If you can see none, it is not well sealed, and your living space is exposed to the attic.

What are the Top Benefits of Installing your Heat Pump

Here are some top pros of installing your heat pump in the attic.

More Living Space

Residential heating and cooling systems are not typically enormous.  However, despite this, they still need a specific space set aside for them.

Having HVAC units in the attic space will free up some floor space. In the lower levels of the house.

Yes, you will lose some space on the attic floor, but the trade remains worthwhile.

Easy Access to Every Room in the House

One advantage of installing a heat pump in the attic is how easy the duct installation is.

It is easy to supply every room with cool and hot air. This is one great way to avoid zones that do not receive conditioned air.

If you want to avoid an uneven climate in your house, an attic heat pump could help solve this issue.

Getting the Best Out of Your Attic Heat Pump System

If you already have your heat pump in the attic or have decided to install it up there, then you should learn to take good care of it. Just like any other HVAC equipment, heat pumps in the attic need routine maintenance to function well.

Here are some tips to achieve the best from

  • Always consult with an HVAC technician as soon as you notice issues such as ceiling leaks, rotting attic floor joists or lack of or reduced conditioned air.
  • Do not just focus on the air handler. Ensure your outdoor unit is working well so that there is no strain on the indoor unit in the attic.
  • Get attic insulation. Poor attic insulation lowers the energy efficiency of the air handlers(1). Ask your HVAC technician to help ensure your attic is well-insulated.
  • Ensure your ductwork is well-insulated too. You can use spray foam insulation for them.
  • Perform routine maintenance to avoid having clogged air filters and a clogged drain line.
  • Periodically go up there and ensure that the AC unit, the duct seals, and the refrigerant line ductwork installed are properly functioning.
