"Extremely well. The house was a rental and the previous tenants had a Golden Retriever dog (long hair). The ducts were clogged with dog hair. The crew arrived on time and went right to work vacuuming every duct and the HVAC unit."

"Integrity Air is A-1 in my book. Great prices, great installers and wonderful customer service. I had been told by other HVAC companies that AC would not fit in the space I had, but Integrity found a way and did a wonderful job. The installers were quick and very courteous, my salesman answered every question I had. And the price was very reasonable, much lower than I expected."

"I was really delighted with the amazing quality of the installation work. The work included breaking through concrete to re route the duct work so that the furnace could be installed in the garage instead of the crawl space. Their work was phenomenal. Most of the other HVAC companies would not tackle this job because it was so extensive, requiring this work with the concrete as well as doing a roof penetration to exhaust the new furnace. the workers were extremely professional and clean. These are the folks to call if you have a complicated retrofit furnace and AC need."

"Ben Fish showed up right on time, went up to my attic space for a visual inspection (something I should have done a long time ago but didn't) and measured the depth of insulation, appliance efficiency, energy loss from floor/walls/windows, and put it on a nice, easy-to-read spreadsheet, as well as throroughly explained everything.  There was absolutely no pressure to buy anything, as there had been in the past with HVAC repairmen.  One reason I wanted this audit was for the impartial 3rd party feedback, which is exactly what I got.

"Very pleasant experience. Punctual and professional. It would have been helpful to know the amount of noise that putting in a new furnace causes, I would have rescheduled some of my business activities, but the job was done well. Duct work was brought up to code and passed inspection. However at my home, there was an issue passing the inspection. They did not vent the air conditioner adequately. When we failed the inspection, they came out on that very day and corrected the problem. There was/is the inconvenience of a second inspection."

"It was really a great experience from the very beginning. I found them online, on an advertisement on my phone. I clicked on the ad, which led me to their website. I filled out the contact form and within 2 hours someone called me to make an appt. They explained over the phone that it would be an "arrival window" of 3 hours, and I was expecting something like that. They called this morning to let me know they were on their way, which I thought was very nice. The technician, Dave, arrived at the very beginning of their "arrival window", which was also nice. The technician arrived in a nice, professionally lettered company van, which I appreciate. You'd be surprised how many companies DON'T do that. Dave was in a nice uniform, seemed clean-cut and pleasant. I showed the him around to where my furnace, thermostat and A/C unit were and left him to do his thing. All I had requested of them was a tune-up and just a once-over on both the furnace and the A/C unit. Just some preventative maintenance, so that we wouldn't have any problems [that could have been prevented] this winter with the furnace or next spring when we went to turn on the A/C unit. He did find some things that needed replaced and cleaned out with our A/C unit and said he was surprised to hear it was still working well. It would have probably failed next season if we hadn't have had him out to fix these problems. There wasn't much wrong with our furnace, but I was glad he checked it out. He replaced our screens in our furnace. That was cool that this was included as part of the service call. He also stayed and talked with me for 5-10 minutes about the age of my furnace, what to keep an eye out for, and how much longer I should expect it to last. That was very nice and I could tell he really knew his business well, which added to my confidence in this company. The service took about 90 minutes and I felt the price they charged was very fair. It was probably more than some companies charge, but I would rather have a really professional outfit for a little more money than save money and have a less professional company. So to me, the rate I paid was a good value. I was just impressed all the way around with this company and with Dave. I'd recommend this company to anyone looking for HVAC work. They are a professional outfit, all the way down the line.

"They did a great job in a timely manner for a good price. I would recommend them. They came out and attempted to fix my furnace. The initial fix solved one problem, but then an even larger problem was found. At that point they recommended replacing the furnace as it was already on its last leg anyway. I got a quote for work from them and 2 other companies. The other companies agreed a replacement was the best option. Integrity Air had the best price. Their technicians were very friendly and explained what they were doing during all steps. They were prompt with their service. I had a secondary source for heat (gas fireplace inside), so I was in no rush and had the service calls when it was convenient for my schedule. They did have appointments available sooner had I wanted and needed the heat fixed sooner."

Heating and Air Conditioning questions, answered by experts

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
