Signs Your HVAC System Needs To Be Replaced

1. Strange Sounds and Smells

A properly working HVAC system should run quietly. Even the tiniest squeak or malodor calls for your system to be inspected immediately. There may be mold in the ducts, wires melting, or something far more severe happening in your HVAC system.

2. Imbalanced Temperature

An old HVAC system will have trouble sustaining consistent temperature, especially without annual maintenance. There could be underlying maintenance issues left unaddressed, like cracked ducts, low fluid levels, clogged filters, or a faulty or damaged thermostat. These temperature inconsistencies can mean that your HVAC system isn’t working at optimal conditions or isn’t properly installed.

3. Overpriced Repairs

When your HVAC system is over ten years old, frequent repairs and replacement are inevitable. It’s when these repairs start burning through your emergency funds like a wildfire that something may be wrong. When you call DunRite, we will fully diagnose your HVAC system and guide you towards your best course of action, whether it’s continued repair or replacement.

Our highly-trained technicians have extensive experience in providing HVAC repair in the Portola Valley, CA, area. We don’t focus on sales, so we try to repair units that can still be salvaged and restored to their optimal condition.

4. Exorbitant Energy Bills

Energy bill fluctuation is normal, but when they start to skyrocket, your HVAC system is in dire need of immediate service and possible replacement. Experts say that installing a new HVAC system can reduce your energy bills by as much as 20 percent. Don’t wait for your finances to empty before calling us.

How To Choose a Good HVAC System

If you plan to buy a new HVAC system, seek help from a trusted HVAC company in the Portola Valley, CA, area like DunRite. We help people look for suitable units for their properties. Here are a few of the factors we consider:

Filter and Air Quality Specifications

We look for units with the best filter and air quality specifications when looking for sound HVAC systems. Since they bring in outdoor air, their filters must be the best quality to keep the air free of any pollutants. The indoor air becomes stale without the mentioned specifications, allowing mold spores, allergy-inducing dust mites, and pet dander to hinder indoor air quality.


The size of the HVAC system is another factor that we consider for a property’s suitable unit. Large properties have considerable heating and cooling load, so heavy-duty HVAC units with high capacities are most appropriate. When the chosen unit is too small or bulky, it won’t perform efficiently. If anything, it will drive monthly energy bills up without properly regulating the ambient temperature.

The two factors above are just some of the things we consider when looking for HVAC systems. With us at DunRite, you are guaranteed the best and most suitable systems for your property. We also provide HVAC installation in the Portola Valley, CA, area.
