Duct sealing improves comfort and lowers energy bills.

If you want your Malta home to be more comfortable, more energy-efficient, and to have cleaner breathable air, then duct sealing is for you!

Reduced airflow and energy loss are caused by leaky ducts. PV’s air duct sealing services deliver significantly better HVAC performance that further enhances indoor comfort.

Who needs air duct sealing services?

A typical home loses 20 to 30 percent of its conditioned air to unsealed or poorly connected ducts according to a study conducted by the EPA. That's just unacceptable and expensive!

Here are signs that you have leaky ducts:

  • High utility bills in summer and winter

  • Difficulty heating or cooling some of the rooms

  • Visible dust and grime inside your ducts

Unless you are absolutely certain that your air ducts were sealed, you might not be getting the most out of your HVAC system if you see excessive dust, pests, and insects. These are signs that your air ducts were not sealed. Consider the benefits of having your ducts sealed and enjoy the following:

  • Better airflow and comfort

  • Improved heating and cooling among rooms

  • Lower utility bills during high use seasons

  • More comfortable humidity levels throughout the year

  • Cleaner air since the ducts will not pull it from the attic or crawlspace

Why M&E?

Materials: We start with actual duct mastic and genuine mastic tape, and not sub-standard materials.

Connections and joints: Before testing, we seal all areas where duct materials connect.

Duct blaster: After the initial round of sealing, a duct blaster test is completed to visibly isolate areas of leakage. We seal these areas then repeat the test.

Pressure test: Using special equipment, we test the pressure inside your ducts to determine the actual level of duct leakage. We keep sealing and testing until we hit the 4% target.

Insulation: After we get duct leakage down to 4%, we insulate your ducts.

Access door: Yep, air can leak out of the access door on your indoor HVAC unit - so we tape the door too.

Duct sealing is extremely important, however, leaky ducts are not always the sole problem.

At M&E, we analyze your ducts to identify the best ways to improve comfort and reduce energy loss.

Sometimes, meaning prioritizing ductwork modification like reinstalling existing ducts, replacing damaged or failing ducts, or ensuring you've got ducts that are appropriate for your home.

We look for all possible issues because duct sealing might just be a band-aid for a bigger problem. That's why we will work with you to select the best service that would meet your needs and budget.
