When To Call Us For Service

We can address the following problems with your heating system:
  • Compressor problems: If the compressor fails, whether due to damaged bearings, contacts, or a motor, heat exchange will be affected, and your heater won’t work at all.
  • Temperature fluctuations: Frequent changes in temperature, even when you set the thermostat, indicate a problem in the system that we can find and fix.
  • Lack of heat: Insufficient heating may mean a clogged filter or improperly sized furnace, while no heating can be due to a range of problems.
  • Low air pressure: A lack of air coming from your HVAC vents can mean there’s an equipment problem or blockage in your ductwork.
  • Dirty filters: If a filter is dirty or clogged, it reduces airflow, which makes the furnace work harder; this can damage the limit switch (which controls the fan).
  • Lack of maintenance: Periodic checks can prevent unexpected problems; routine maintenance can avoid breakdowns and improve reliability and efficiency.
  • Rising energy bills: If your heating system is using more energy, your utility bills may go up unexpectedly; if so, an inspection can help identify the problem.

Also call us if you notice your furnace frequently cycling between on and off, the blower runs continuously, or there is loud rattling, squeaking, or rumbling coming from the unit. Serious mechanical issues may be present, or the burner might be clogged, which must be addressed immediately.

Heating repair isn’t always enough. It may be time to install a new furnace if:

  • The unit is 15 years old or older.
  • A drop in efficiency is noticed.
  • It frequently needs to be repaired.
  • The repair cost is very high.
  • Our technicians suggest a more efficient replacement.

Heat Pump Repair

If your heat pump isn’t producing heat, the thermostat may not be properly adjusted. The wrong thermostat may have been installed, or there may be a lack of power from your main electric panel. From dirty air filters to problematic coils and fans, a lack of heat can have many causes. NexGen technicians can service the system to fix any issues, even if outdoor coils and supply and return registers need to be cleaned or the heat pump fins are bent. Reduce airflow, even from dirty filters, can damage the compressor. Cold air from the vents signals a problem as well, which may involve the thermostat or air handler. A defective control module or defroster timer may be to blame, while low refrigerant levels or blockage by leaves or grass can also trigger a problem. We can fix or replace air filters or malfunctioning blowers if the unit isn’t cycling correctly. Air filters can usually be replaced without a technician, but other heat pump issues can be too complex to fix unless you have the proper experience. That’s where our professional HVAC technicians excel. Whether there’s not enough heat or the pump sounds like something is loose or makes other odd noises, our repair experts can find the source and recommend the best options to get your heating system up and running again.

Amazing Reviews From Our Loved Clients

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.
Jack W.
My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
