Your Ductwork Is Quietly Costing You Money
The Department of Energy has concluded that over 25% of the money you spend to heat or cool your home is lost in your ductwork. In some houses, over 50% of the air meant to be inside your house is lost through leaking ductwork.
Sealing and insulating services can combat this issue. At MightyServ, our NATE-certified technicians are trained to complete comprehensive duct services that leave your home more efficient and your air cleaner.
Signs Your Ducts Need Attention
Duct Services We Provide
We offer duct services in Canoga Park and throughout the San Fernando Valley to keep your air clean and your heating and cooling systems running efficiently.
Duct Sealing
After an assessment of your home, we may recommend sealing your ducts with mastic, metal tape, or spray-on sealant and balancing the duct system to optimize airflow to all rooms.
Duct Repair
Damaged, collapsed, or disconnected sections should be repaired or completely replaced. We’ll determine whether a flex duct or hard duct is best for your home.
Duct Insulation
Insulating ductwork in attics, crawlspaces, and basements can save energy and make your home more comfortable. In the Los Angeles area, where temperatures often climb, duct insulation helps you keep cool.
Duct Cleaning
Keeping your ducts clean is vital to maintaining the quality of the air in your home. Clean air ducts will also help your HVAC unit operate at peak efficiency, saving you money on monthly utility bills.
Duct Sealing: Stopping the Waste
Ducts develop leaks over time due to age, improper original installation, or pest damage. Leaky ductwork and poor airflow can result in stuffy, uncomfortable rooms regardless of the thermostat setting.
After an assessment of your home, we’ll seal any leaks with mastic, metal tape, or spray-on sealant, depending on the duct type and location. Afterward, we’ll balance the airflow and ensure no duct leaks remain. As a result, you can expect less energy waste and savings on your energy bill.
Duct Repair Services: When Sealing Isn’t Enough
There’s a difference between gaps and true damage. Gaps result in small leaks that can be easily sealed. But damage such as disconnected or collapsed duct sections requires full repair and replacement. In the San Fernando Valley, this kind of damage usually results from pest infestations, DIY fixes, mistakes during original installation, and simple aging in older homes.
After assessing the damage, we’ll walk you through your options, including flex vs. rigid duct repair. The assessment will determine the scope of the fix, and we’ll clearly communicate our recommendation and the cost — no surprise fees or upsells.
Duct Insulation: Keeping Conditioned Air Where It Belongs
Uninsulated ducts in attics and crawlspaces are often the reason for lost efficiency. That’s because conditioned air absorbs heat from the surrounding unconditioned space. Houses of all ages, styles, and sizes can benefit from insulation, especially for SFV homes with attic ductwork as summer temperatures climb.
We offer cost-effective insulation that maintains balanced interior temperatures year-round. Our experienced team installs premium insulation with proven, innovative techniques in just a few hours.
It’s important to note that duct insulation is a separate service from attic insulation, though both are beneficial and can be performed in the same visit.
Duct Cleaning: Air Quality From the Inside Out
We highly recommend regular duct cleaning every 3 – 5 years, or more frequently in homes with pets or allergy sufferers. After a renovation, duct cleaning should be the last step to clear out construction dust.Duct cleaning is crucial for the performance and longevity of your heating and cooling system. Over time, dust, debris, allergens, and even mold can build up, leading to poor air quality and flare-ups in people with asthma or other respiratory conditions.
We offer cost-effective insulation that maintains balanced interior temperatures year-round. Our experienced team installs premium insulation with proven, innovative techniques in just a few hours.
During a duct cleaning service, we’ll use a powerful vacuum cleaner to create suction throughout your system. Then, our technicians will use tools to dislodge debris until it’s pulled into the vacuum. To finish, we clean the registers, grills, heat exchanger, and blower motor. The whole process takes about 3 – 5 hours — a relatively quick investment in your home’s comfort and your family’s health.
Attic Insulation Services
At MightyServ, we specialize in blown-in and sprayed-in attic insulation. There are many types of insulation to choose from, and much of the choice comes down to climate. The more extreme the weather conditions, the more “R value” (resistance to heat flow) you need. Many insulation products are made with cellulose, an environmentally friendly material. They’re also often non-invasive, keeping your structure intact while providing weather protection.
When you schedule an attic insulation service with MightyServ, we’ll assess the temperature in your area, measure your crawlspace or attic, and recommend the type of attic insulation that best fits your needs. Then, we’ll install it in a time-efficient manner with a provable energy-saving outcome.
We’re also available for new construction insulation installation. New construction is the perfect opportunity to install high-quality insulation products. Our premium-grade insulation will not only reduce your energy bills and decrease your environmental footprint, but also provide a comfortable home for your entire family.

Frequently Asked Questions
Duct sealing services detect and repair leaks, gaps, and cracks in your ductwork using methods like mastic sealant or flexible tape. You might need duct sealing if you have high energy bills in the summer and winter, experience uneven temperatures from room to room, or have ducts located in an uninsulated attic or crawl space.
The main benefit of duct sealing is a more comfortable, energy-efficient home. As a result, you may also see a decrease in your energy bills.
In many cases, yes. Modern high-efficiency furnaces use less energy to deliver consistent heat, helping reduce monthly utility costs while improving overall comfort.
HVAC duct insulation involves wrapping air-handling pipes with foam or fiberglass insulation. It prevents heat transfer from the cool, conditioned air inside the pipes to the unconditioned air outside. The result is increased energy efficiency and energy cost savings, along with a lower chance of moisture buildup and mold growth.
If you notice uneven temperatures across rooms, higher energy bills, or signs such as tears, sagging, mold, moisture, or pest damage in your ducts, it’s time for a replacement. If your system is over 10-15 years old, it’s likely also time for a replacement, as the insulation may have lost its effectiveness.
We serve the greater West Los Angeles, CA area, including San Fernando Valley communities such as Burbank, Encino, and Van Nuys. We’ve been proudly locally owned and family operated in Canoga Park since 1963, so we know Valley homes inside and out.
Ductwork repair seals leaks and prevents the circulation of pollutants like dust, mold, and allergens. The result is consistent, fresh air and a lower risk of mold growth due to humidity buildup. It’s healthier and more pleasant to breathe.
Yes. Leaky ducts are less efficient because they allow air to escape, causing your heating and air conditioning system to work even harder to maintain consistent temperatures. Over time, this can strain your equipment, lead to early failure, and drive up your utility bills.
If you’re experiencing unexpectedly high utility bills, uneven temperatures between rooms, weak airflow, whistling/rattling sounds near vents, a constantly running system, or excessive dust, the culprit may be your ducts. To check, look for physical signs of damage on your visible ducts and place your hand over vents to check airflow strength in each room. We also recommend checking for insulation material stuck to your air filter, which can indicate a serious leak on the return side.
