Common Issues

Blocked HVAC Airflow

Restricted airflow can lead to hot or cold spots, humidity problems, air stratification, higher energy bills, and wear on your system. Extreme blockages can also lead to premature failure of HVAC components.

Boiler Not Heating Properly

Boilers that fail to heat or maintain consistent performance may be experiencing problems with the valves, pumps, expansion tank, thermostat, or circulator. Other common issues include air trapped in the system, sediment buildup, or insufficient water flow.

Dirty HVAC Coils

Dirty evaporator or condenser coils reduce your system’s ability to transfer heat, lowering efficiency.

Dirty or Clogged Air Filters

Neglected air filters can restrict airflow and lower system efficiency, leading to higher utility bills.

Dusty or Stale Indoor Air

Poor air quality, increased dust, or musty odors can result from dirty HVAC filters or mold/mildew in your ducts or unit.

Furnace Ignition or Burner Failure

A furnace that won’t ignite or produces weak heat likely has burner or ignition system issues. This can either be a maintenance item or a failed component.

General HVAC System Issues

Common issues include blocked vents, dirty filters, and restricted airflow, as well as improper system settings or lack of regular maintenance—all of which can negatively impact energy efficiency, system performance, and overall indoor comfort.

HVAC Fan Motor Not Spinning

If the fan motor in your HVAC unit fails, air won't circulate properly, impacting both heating and cooling.

HVAC System Making Strange Noises

If your heating or cooling system is making loud banging, squealing, or clicking sounds, it's indicative that a problem exists that should be addressed immediately to prevent failure.

HVAC System Short Cycling

HVAC units that frequently turn on and off may be experiencing thermostat issues or airflow restrictions, reducing efficiency. Cycling puts heavy, unnecessary wear on your compressor and refrigerant circuit. This can also result in humidity problems.

Home Heating Not Working

If your heat pump or furnace isn’t starting or warming your home, it could be due to a faulty thermostat, pilot or ignition failure, a bad blower motor, clogged filters, or a tripped breaker. Heat pumps may have refrigerant leaks, defrost cycle problems, or outdoor unit issues. Poor airflow or lack of maintenance can also impact performance.

Leaky or Damaged Ductwork

Holes or loose connections in your ductwork can waste heated or cooled air, lowering system performance.

Poor Airflow from Vents

Weak or inconsistent airflow from your vents can reduce comfort and increase energy costs, often due to clogged filters or duct issues. Other problems include stagnation and cold floors.

Spiking Energy Bills

Unexpected increases in energy costs can result from HVAC inefficiency, dirty coils, dirty filters, failed thermostats, or malfunctioning components.

Thermostat Not Working Properly

Inaccurate temperature readings or unresponsive controls are signs your thermostat needs repair or replacement.

Uneven Home Heating

Cold spots in certain rooms often point to thermostat miscalibration or ductwork problems in your heating system. Often, issues can be caused by stagnation, poor air flow, or system return issues.

Patrick is polite and very informed. He shows concern and makes recommendations to address anything that could be problematic or preventative for future issues with our furnace.

Daniella A.

We moved into an old home with an old oil furnace that we knew was on its way out. Joe, David, and crew were great and replaced our old furnace with a new one. We had only one issue which was that the additional room that was added onto this house in 2010 didn’t include a way to bleed out the baseboards. They found a solution and fixed the issue. Dual temp is a great company with great people!

we were on vacation when our air conditioner went on the fritz with only our dog sitter at our house. We called Dual Temp and they got a guy out there the next morning to work on it. The technicians name was Patrick, who is definitely accredited, his profession, very professional and friendly, got our system up and running in no time answered all our questions Any potential problems that we have that need to be addressed. What a great experience. These guys put us at ease and took care of our problems so it didn’t affect our vacation. Thank you, Dual Temp and Joe

Stephanie R.

I can’t say enough good things about our experience with Dual Temp. After several issues with our AC over the last several months it was determined that it was time to start looking for a new system. I called on a Friday morning to request a quote. They were able to have someone come out the same day. Joe was great. He was very nice and answered my husband’s questions as well as address a concern we had with air flow to our bedroom due to a smashed piece of ductwork that’s been that way apparently since the house was built. I had an estimate in my email around 5 PM that same evening. We were provided with 3 options in the quote. Sort of a good, better, best option. We had a few additional questions which I emailed Joe about and he was very quick and responsive to my questions. After getting one other quote from another company we decided to go with Dual Temp. After only 2 weeks from the initial quote our new system was installed this week. Patrick and David were the technicians that came to install and they were just as amazing to work with. They were polite, knowledgeable and explained the system and new thermostat very well. I am not one to typically write reviews but I do read them while doing my research. I can only suggest that you give them a chance at addressing your needs. Thanks again for the great service. I look forward to the same great service in the future for routine maintenance as needed.

Mateo S.

David came out and did a great job and was done within an hour. didn’t try to sneak in any kind of fees or charge for extra time.

Monica H.

We have only been working with Dual Temp for approximately two months, but we cannot say enough good things about them. Our commercial building has a unique HVAC system, to say the least, and we have already had several occasions on which we have had to make service requests. Dual Temp responds to calls and emails quickly and keeps the customer updated of progress. Nate and his great team of techs—specifically, Noah, Jeff, Bill and the other Noah—are all knowledgeable and very relatable when sharing information and options. It was a very lucky day for us when we connected with Bob, our Dual Tech salesperson, who is diligent about keeping in touch to ensure our needs are being met. Dual Temp now has our finicky HVAC equipment up and running, and we are most appreciative!

Grant J.

Joe was professional and personable. He shared all relevant information and added much to our understanding of what was available. A really good interaction.
