How can you tell if you need emergency HVAC repair in Boston, MA? Several signs indicate issues with HVAC systems. Chilli Willie Mechanical discusses the wicked signs that constitute an HVAC emergency in this blog post.

Signs Indicating the Need for Emergency HVAC Repair | Emergency HVAC Repair In Boston, MA

Inconsistent Heating & Cooling Temperatures

If you have noticed your residential interiors are still stuffy when the AC is running, or there are cool zones in the house with the heating on, it indicates HVAC problems. There could be issues with blocks or clogged ducts, or the outdoor unit needs maintenance. A more direct cause could be a faulty thermostat.

Spiking Energy Bills | Emergency HVAC Repair In Boston, MA

You might have to call in emergency HVAC repair in Boston, MA if your energy bill arrives too much on the high end. It can also indicate that your unit needs to be replaced.

However, the real reason behind high energy bills (apart from energy efficiency issues) is installing the wrong unit size, possibly one with an insufficient Seasonal Energy Efficiency Rating. Our technicians can help you secure a suitable Energy Star Rating replacement unit.

Leaks & Condensation Puddles

HVAC units, if poorly maintained & installed with poorer drainage, will start backing up condensate and clog. You might notice water vapor condensing on the unit, with leaks developing around critical electrical connections. It can also be sure to dust & debris stuck along the drain channels & causing the condensate to pool around unintended exit paths.

What Counts as Emergency HVAC Repair?

While HVAC problems develop with poor maintenance & long duration of usage, some issues can’t be ignored and must be dealt with as soon as possible. Failing to do so might cost you the HVAC unit.

Lack Of Air Flow at The Vents

The lack of airflow from the internal HVAC unit & vents is a complex problem to detect. When you set your thermostat to a specific temperature, it will take a while to realize that nothing is warming up or cooling down as needed.

This calls for emergency HVAC repair because your HVAC’s blower motor is out. The motor is responsible for shunting air to the various areas of your home. If it is not functioning optimally, it will overheat & suffer damage. Additionally, your home will take longer to reach the thermostat’s set temperature.

Rule of thumb, if poor heating or cooling coincides with a slightly burnt smell at the vents, call in for emergency HVAC repair.

The Unit Is Not Expelling Heat | Emergency HVAC Repair In Boston, MA

The heat pump is like the heart of any efficient HVAC unit and should be cared for as such. A lack of hot air expelled at the external unit is considered an HVAC emergency. It can occur at the external unit when interiors are being cooled or at the internal unit when it is too cold.

It could indicate a problem with the heat pump, or the outdoor unit might be clogged by debris, rodent nesting, or dirty filters.

The Cooling Mode Is Blowing Warm Air

This can be quite a dire emergency, especially if you have young children or older adults at home. Hot air from an HVAC set to cool indicates you’re out of refrigerant. Suppose your HVAC does not produce cool air as required. In that case, it is better to call in emergency HVAC repair in Boston, MA, or you risk overheating the heat pump and leading to further problems.

There Is a Strong Smell of Gas

HVAC refrigerants are usually maintained at high pressure, so they will hiss if there is a leak. If the leak is not audible, you will notice a strong scent ranging from rotten eggs to chloroform or a sweet ether. Try not to breathe in the gas, and call in for our emergency HVAC repair services.

Burnt Plastic & Smoke Fumes

While refrigerant leaks have a sweet scent, electrical fires & burnt plastic are far more troubling. The burnt smell could indicate a component overheating, shorting out, or wiring failure. The best thing is to turn off the unit and detach it from any electrical sockets, then contact for emergency HVAC repair.

However, if the smell is electrical & dusty, there is a chance some debris is burning off in the unit, and the smell dissipates after a while. It usually happens if the unit has not been used in a while or has not been maintained for the season.

HVAC Components Requiring Regular Replacement

Air Filters | Emergency HVAC Repair In Boston, MA

Dirty filters can obstruct air flow & stress the HVAC components. They can also degrade the heating & cooling efficiency of the unit & accelerate equipment deterioration.

Condenser Unit Components

The said components regulate the power to the system compressor. They require high voltage and generate a lot of heat that can damage the contactors & capacitors. Thankfully they are replaceable components.

Blower Motor

The motor is located in the indoor unit of HVAC installations & it is active during both the cooling & heating seasons – meaning it gets a lot of wear & tear – in fact, more than all components combined. If you don’t require a replacement, you should still hire an HVAC contractor for maintenance to keep any HVAC problems at bay.


Low refrigerant levels can result from leaks by a breach in the refrigerant lines. It is optimal to have your HVAC service every season to ensure optimal refrigerant levels & to remain aware of leaks.

A Word of Caution | Emergency HVAC Repair In Boston, MA

Suppose you require emergency HVAC repair in Boston, MA. In that case, it is best to call professional technicians than attempt a DIY fix. As far as air filters are concerned, their replacement, cleaning & installation can be managed at home. But other components that are of an electrical or electromechanical nature should best be left to certified technicians.
