Signs your home needs air purification
Spencer’s licensed HVAC technicians have been improving indoor air quality for North Shore homeowners for over 45 years. If you notice any of these warning signs, call us for a free estimate.
Persistent allergy symptoms indoorsWhat we check
If allergies or respiratory symptoms are consistently worse inside your home than outside, airborne pollutants are likely circulating through your HVAC system. A whole-home air purification system can reduce allergen concentrations in the air that moves through it.
We check the filter the system uses now, how long the fan runs, and what a better filter or purifier would need.
- Current filter size and rating
- Fan run time
- Space for a filter cabinet
Excessive dust buildup despite regular cleaningWhat we check
Homes that accumulate dust quickly on furniture and surfaces often have inadequate filtration. Standard 1-inch furnace filters only capture large particles, allowing fine dust and allergens to pass through and settle throughout your home.
We look for leaks in the return ducts that pull dust in, then at the filter that should be catching it.
- Return duct leaks
- Filter fit and bypass gaps
- Duct cleanliness
Lingering odors from cooking, pets, or chemicalsWhat we check
Persistent odors that air fresheners only mask indicate volatile organic compounds and biological matter in your air. Photocatalytic oxidation (PCO) purifiers are designed to reduce odor-causing compounds in the air that passes through the system.
We check ventilation first, then whether an in-duct purifier fits the system.
- Kitchen and bathroom ventilation
- Fan run time
- Duct space for a purifier
Family members with respiratory issuesWhat we check
Asthma, COPD, and other respiratory conditions are aggravated by poor indoor air quality. Better filtration reduces the airborne particles that move through the system, which many sensitive households find more comfortable.
We match the filter rating to what the blower can move, so cleaner air does not cost airflow.
- Blower capacity
- Filter rating the system can take
- Return air paths
Pet dander affecting household comfortWhat we check
Pet owners on the North Shore know that dander, hair, and associated allergens are nearly impossible to control with vacuuming alone. Higher-rated whole-home filtration captures more dander as the air passes through the system, before it recirculates through your ductwork.
We check how often the filter clogs and whether a deeper media filter would last longer.
- Filter change history
- Media filter cabinet fit
- Duct cleanliness

What changes the work and the price?
The exact price comes after we see the system. These are the factors that most often change the work.
The equipment chosen
A filter cabinet, a UV light and an in-duct purifier are different parts and different labor.
Space at the system
A filter cabinet needs room on the return side of the furnace or air handler.
Airflow
A higher-rated filter has to suit the blower, or the duct size may need attention.
Power and access
A UV light or purifier needs power and a reachable place for service.
Our work is backed by a lifetime workmanship warranty for the typical lifespan of the installation. Terms apply.

Frequently asked questions
Call 978-293-5770What types of air purifiers does Spencer install?
Spencer installs media filter cabinets with higher-rated filters, UV germicidal lights, and photocatalytic oxidation units. We assess your home and recommend the right combination based on your specific air quality concerns and existing HVAC setup.
How much does a whole-home air purifier cost?
The price depends on the equipment you choose, the space at the furnace or air handler, and the power and access it needs. Estimates for installations and replacements are free. You get the exact price before any work begins.
How effective are whole-home air purifiers?
It depends on the equipment and on how much the fan runs: a whole-home system only treats air that passes through it. A higher-rated media filter captures more fine particles than a standard 1-inch filter, and a UV light keeps the coil it shines on cleaner.
How often do air purifier filters need replacement?
Media filters typically last 6 to 12 months, and UV bulbs are usually replaced about once a year. We tell you the schedule for the equipment we install.
Are whole-house air purifiers worth it?
For a household bothered by dust, dander or odors, a system that cleans the air on every pass through the furnace or air handler covers the whole house without portable units in each room. It does the most when the fan runs often.
What MERV rating should I use?
Many homes do well with MERV 11 to 13 in a deeper media cabinet. A thin 1-inch filter at a high rating can restrict airflow, so we check what your blower can handle before recommending one.
