Denver HVAC Repair

Good Evening HVAC Team, I deeply appreciate your team for getting back to me quickly yesterday evening so I could schedule an appointment for my gf's place(definitely something has been wrong for a while)-- The technician Alberto showed up within the 2 hour window that was appointed to us (WITHIN the 1st half hour!!!). BIG THANK YOU for being honest, and advising us that for some reason the fuse/switch was in the reverse position so the AC unit would not properly turn on. The unit turned back on immediately, and began cooling the house. And then providing advice that the AC/Heating system needed some TLC, and giving us options to save money by purchasing a maintenance plan that included the filters plus cleaning services since we were already being charged for the service today. My personal thanks for being extremely professional, and personable as you entered our home. Solving the technical issue is only part of the job, but providing great Customer Service, and Cost Effective solutions are reasons to recommend you to the people who are looking for the same type of service. Also, it was very convenient that you were able to take my payment over the Phone(FaceTime) since I was not present at the time. Your company website is well organized, and I had no problem reviewing your capabilities as well as how to contact your team. Most important, Tina spoke very highly of you, and made her feel comfortable through the process. SO BOTTOM LINE to other customers looking for HVAC service: LOOK NO FURTHER!!! If you have a AC/Heater Issue, give this the HVAC company a call, or email-- You won't be disappointed. Kind Regards, Michael
AC air handler buzzing sounds. Do you hear a buzzing sound when you turn on the thermostat? The only thing that comes on in the house when you turn on the thermostat is the fan relay and fan in the air handler or furnace. Try switching the thermostat HEAT/COOL switch to OFF. Then switch the fan switch from AUTO to ON. The fan (only) should come on. If the air handler makes a buzzing sound, it probably has a bad fan relay or, more likely, blower fan.
Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants. A refrigerant is employed either in a heat pump system in which a compressor is used to drive thermodynamic refrigeration cycle, or in a free cooling system which uses pumps to circulate a cool refrigerant (typically water or a glycol mix).

My mom just received service from this company. She paid $609 to have her frion replaced. After two uses the AC stops working. A young rep comes out to the house again and notifies her that her entire AC unit and furnace need to be replace for just shy of ten grand, though when her frion was refilled she was told that her system should last another five years. When they came back to tell her how her entire system needed to be replaced, they were generous enough to offer her a $300 credit on the nearly $10,000 estimate of replacing the entire system that was working fine until they touched it. My best assumption would be that there is a mishap with the system is due to their negligence. Id suggest using another company other than these scam artists. Update: Alberto soon messages me about the negative review telling me how I am wrong and that they are the best mechanical contractors in the Bay Area. Literally told me that I was wrong. Not sure how you can get much more arrogant than that. Stay clear of these clowns.

Our A/C was blowing hot air intermittently...it was cold one minute and warm the next. By 8pm I'd have a 90 degree interior temp. After one company just took a cursory glance at our A/C and found nothing wrong, I called HVAC. I called them mostly based on Michael W's post on 8/10/14 where he told us the owner, Alberto, took his feedback and took it SERIOUSLY. That speaks VOLUMES to anyone who has been around long enough to know the characteristics of the serious players are and those who are the wannabes. So HVAC sent Tony Diaz to my house. I was at work so he was subjected to the most excruciatingly exacting woman on the planet (my wife). Tony impressed her with his friendliness, professionalism and the obvious jouneyman-level knowledge of his craft. He found literally --burnt-out-- parts in our system and replaced them. It cost us a bit but I know enough about the parts to see there was no gouging on the parts and a fair rate for the labor. It wasn't cheap but it was fair and worth every dime. And now i have A/C in my house again and a repairman came to my house, actually FIXED something AND managed to do so in a friendly & professional manner. That used to be commonplace...nowadays it deserves a "Wow".. Thank you, Tony!
I have a tankless water heater that began to leak. I called around and settled on Bill Howe. Jason came out on Monday and immediately pinpointed the issue. He called the manufacturer, explained what he saw, took a couple of pictures and said he will be back in a couple of days with replacement parts. A few days later Jason called to say he was on his way. He showed up and completed the work in about an hour.

We live in a recently completed townhouse that was built with double-wall construction. That construction method was touted by the builder as what would keep sound from penetrating between the units. But we can hear the next door neighbors' TV and stereo, and sometimes voices and even snoring, through the wall. While sometimes it's the volume, mostly it's the bass sounds coming through the wall. They say they don't hear us, but we keep our bass turned down. They crank up the bass, and they are not going to change that. They also are not going to do anything construction-wise to help from their side. What is the best way for us to try to block the low frequency/bass sounds from penetrating the existing wall into our side?
Once a diagnosis is made to your air-conditioning and/or heating system, the unit can be repaired, in most situations, with stock HVAC parts off the truck. Sometimes the HVAC part has to be ordered because it is a specialty part that only the HVAC manufacturer of your equipment can provide. If the part can be picked up locally then you can expect to pay for travel time to and from the HVAC parts dealer. It is practically impossible to carry every single HVAC part for every single HVAC breakdown that occurs.
If your air ducts have been damaged, you’ll need to replace them. The national average air duct replacement cost is $150-$280, which may not include materials. Factors such as duct material, labor, location of ducts and linear feet of ductwork will all affect your final costs. Labor costs will vary based on how accessible the ducts are and what material your ducts are made of. The least expensive duct material is a flexible, non-metallic ducting that costs approximately $1-$2 per linear foot. Flexible aluminum is generally more expensive and stronger than non-metallic ducting. Stainless steel ducting is the strongest, the least flexible (meaning installing it typically has higher labor rates), and usually the most expensive. An average price for air duct replacement could range between $35 and $55 per linear foot, including basic materials and labor. A typical single-family home has 6-10 duct runs; replacing or installing one duct run could average $150-$250 for labor.
If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. Lastly, a good HVAC service tech will attempt to find the refrigerant leak within the hour’s air conditioning service you are paying for in addition to the refrigerant charge.

Poor dehumidification can also be caused by excessive humidity in the home. This may be caused by water leaks or open windows during humid periods or by a lack of proper condensate drainage from your evaporator coil in the furnace's plenum. A properly functioning cooling unit produces condensate and drains it away. If your unit is not producing condensate its cooling and dehumidification functions are not working properly.

Low refrigerant charges take away from the life of the compressor. The compressor is cooled from the return refrigerant vapor. When there is a low charge there are fewer vapors to cool the compressor, therefore it runs hotter. Any compressor (or electric motor for that matter) which runs above the recommended temperature range will have a shorter life span and cost more to operate.


If you believe that the ac not working or you’re getting little or no cold air, check these three things first. Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home. If you’ve changed the filter and opened all the registers and you’re still not getting airflow at the registers, deice the A-coil. Move the thermostat mode switch from “Cooling” to “Off” and move the fan switch from “Auto” to “On.” Let the blower run for at least 30 minutes or until there’s good airflow at the registers. Then turn the AC back on to test it. If it works for the next 12 hours, you’ve solved the problem.
