Air Duct Cleaning Denver AC Blows Hot Or Warm Air

A few things are more convenient than an AC unit that only provide warm air. Before you do anything, double-check that the thermostat settings have not changed. If your thermostat setting is proper, the first step you can do is to change your air filter. Old congested air filters typically cause AC problems such as frozen coils. 

If the air filter is not the problem, you may be lacking in the refrigerant. Feel the biggest copper wire that leads to the system’s condenser to see if this is the case. Your levels are exceptional if it is wet and chilly to the touch. If it lacks either one of those facets, the refrigerant level is low. You should call professionals offering AC Repair and Maintenance Services Denver to repair the refrigerant reservoir.

Noisy Air Vents

Noisy air vents are the common signs of trouble. Loose ductwork connections often cause rattling and clamoring noises, covering those rattling ducts with metal tape before they drain your wallet. Bangs and loud pops are usually ductwork contraction and expansion due to temperature variances. Ensure your air ducts are well insulated.


A grinding noise perhaps means that two metal parts are grinding against each other. This is very risky because it can produce sparks that start a fire. If you get anything like this, shut off your HCAC and repair it as soon as possible.

High Internal Humidity 

High internal humidity is one of the most common HVAC and indoor air quality problems during the cooling months. The only way to control high humidity in your home is with a dehumidifier. It could be a portable unit or install a whole-home dehumidifier for optimal efficiency and comfort.

Frozen Evaporator

Ice collection on the evaporator coil brings home cooling to a pause- even though your AC may still run and run, dirt collection on the evaporator is a common problem for ice buildup. Remove the ice from the evaporator with a spray can of self-rinse coil cleaner. Perhaps hiring experts offering AC repair and air duct cleaning Denver is your best bet at such time.

Leaking Unit

HVAC units do leak some condensate and fluid. Excessive leakage indicates a variety of issues with many solutions. Typically, the condensate line has a clog. Unclogging is easy for a DIY repair. Make sure to use the manufacturer’s guidelines. If you have any uncertainties, reach out to one of the trained HVAC professionals. 

Dirty Air Filter

Tripping Circuit Breakers

Sometimes, your circuit breaker requires often reset because the system is working too hard. This can be because of a dirty air filter or a more complex problem. Regular checkups and preservation can often clasp these difficulties before becoming a headache.

Blower motor running excessively

Sometimes, the furnace’s blower motor will run because of a faulty relay. Call your HVAC professional offering AC Repair and Maintenance Services Denver and set up an appointment for an evaluation.

Blown Fuses or Tripped Breakers

Is your blower overworking? That’s most likely the reason your furnace stumbled your circuit breaker. Your blower has to work stiffer to force air through the filter if something delays airflow to your system, such as dirt. When your blower works more rigidly, it raises energy consumption and sometimes trips the circuit breaker. Check your filter and change it if need be.

Ignition Problems

A gas supply problem or wear and tear of an ignition component could also cause. It’s best to handle pilot and ignition difficulties by calling professionals offering air duct cleaning Denver.
