"Very good experience with this company from front to back. Great, prompt, customer service from Marshall on the phone when I put in the lead, followed up by a very good experience with Travis and Jimmy on the job. They showed up right on time, despite Travis even being on crutches with a broken foot! They were very friendly efficient and explained everything as they went, and gave some great advice about how to maintain the system going forward. Had a good discussion about getting my fireplace up and running too when the time comes. Definitely will be using this company again for any HVAC needs in the future! "

"I have 2 mini split systems which were bought 2 years ago primarily for AC. Last winter we operated them all the time for heating our house. They performed well down to about 35 F. Since we want them to be in good shape for this winter, I had them inspected. The technician arrived on time, checked the units and condensate drains, cleaned the filters and checked the refrigerant. At the end he informed me of his findings (no problems). A job well done."

"Having been a Premier Indoor Comfort Systems customer for over 10 years, they used to be an honorable company. I can no longer recommend Premier as an honest HVAC company. The short version - Premier came out to perform our summer inspection. One of our HVAC systems could not maintain cooling. Premier claimed we needed them to perform over $2300 of "cleaning" services to restore the function of the A/C system. Their work order noted that they did not check the refrigerant level of the system - a service they advertise on their web site as part of the bi-annual inspection. Not wanting to spend over $2300 on an older system, I contacted another HVAC company for a 2nd opinion. The 2nd company performed the same service, observed that unit was over 2 lbs low on refrigerant, added refrigerant to the system, and restored the system to service for $ 349. I left (2) messages for the service manager Mark Harman and (1) for John Stezzi (business). They failed to return my calls."

"Very responsive to come out ainitially and access damage and get fixed as all was paid for by insurance. They also agreed to installing a skylight where the tree came thru (there was not a skylight before). It was installed well and has never leaked. That's all the good news I have folks. HOWEVER we had 'total replacement to original status' insurance coverage and first go around all they were going to do was patch damaged areas of roof. matching tiles "as best they can". After much bickering back and forth, they finally replaced entire roof. 3 times. yes, three times as the first 2 times work was substandard- and eaked. They did not overlap roof tiles and did not flash properly. When insurance overseer finally agreed to redo entire roof to "original" with a 30 year guarantee, she was subsequently fired by the insurance company after the job was done. Inside the house, the subcontractor they hired to fix our wall and ceiling was horrendous. "Johnny" from Mississippi put up a wall that was not linear -nit bowed. He said our house was crooked and he could not fix that. There was a good 2 feet crawl space between inside wall and outside house. We insisted he redo it (multiple times.) till he got it straight, finally, He said "the wife" was being too fussy. Then he replaced smooth ceiling with a popcorn ceiling because he said he couldn't fix the drywall plaster lines...now we have the task of taking off the popcorn, replacing the drywall ceiling, and replastering correctly. . We grew weary of him and decided not to have him redo. As for coming "on time", well, we learned that "on time" is a relative term...seems to mean just showing up sometime in the morning. Bottom line: Don't let your insurance company bully you into using this company and certainly do NOT hire them on your own."

Air Duct Cleaning questions, answered by experts

Attics are particularly dusty because dirt and pollen enter through cracks in your insulation and then sit untouched for long periods of time. To control dust in your home, it's important to vacuum and wipe down attic surfaces whenever you clean. If you use your attic as a finished living space, consider adding an air purifier or speaking with a roofing contractor about possible openings in the top of your home.

The most common duct sizes used in residential homes are round ducts 6 to 12 inches in diameter. This size is small enough to be easily installed into walls and ceilings, yet is wide enough to allow for adequate airflow through the home. Improper duct sizing can cause HVAC issues, increased energy bills, and a drop in HVAC efficiency, which translates into a less comfortable home. 

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

If you have a forced-air heating system, it’s important to have it professionally inspected at least once per year. During one of these visits, your contractor will look at all of the components of your HVAC system, including your furnace or heat pump, air conditioner, and ducts. On average, an HVAC inspection costs $300. It’s also important to perform basic maintenance between inspections, such as changing your filters and cleaning dust from around your vents.

The frequency of duct inspection and sealing can vary based on several factors, including the age of your ductwork and environmental conditions. Generally, you should have your ducts inspected every two to five years. If you notice a decline in HVAC system efficiency or suspect duct issues, it's wise to schedule an inspection sooner. Regular maintenance can help identify leaks and damage early, possibly reducing HVAC repair costs.
