Company Overview
Indoor air quality holds numerous secrets that you likely don’t know and can’t see. Daily, your home is invaded by as many as 72 trillion microscopic irritants, also known as allergens. These include dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, tobacco smoke, cooking grease, and bacteria. These particles are often so small that your nose and throat fail to filter them, enabling them to enter your lungs. Breathe easier with American Standard's AccuClean air filtration system—it eliminates 99.98% of particles and allergens from your indoor air. This system is 100 times more effective than typical 1"" disposable filters and ionic room appliances. Selecting an American Standard air conditioner or heat pump with the Energy Star label is a crucial step toward saving on your utility expenses and minimizing energy use. What advantages does a unit with the Energy Star logo offer? Air conditioners or heat pumps with this emblem are at least 20% more efficient than the current federal efficiency standards. Investing in an American Standard Heating & Air Conditioning unit with the Energy Star label guarantees you receive the highest efficiency available. Be sure to ask your American Standard Heating & Air Conditioning dealer about local incentives available from many utility companies and financial institutions for Energy Star products.

Recommended Customer Reviews
From the initial call to the HVAC unit back up and running took one week. After gathering multiple quotes and availability to rectify the problem MB was the most reasonable and responsive to my requests. The technician (Oscar) came out the next day to diagnose the problem and was able to identify the problem after an extensive inspection. He verified by calling the manufacturer to confirm his findings. His company immediately ordered the necessary part and quickly rescheduled for the installation. The professionalism, quality of work, and efficiency was on point and I would recommend their services to anyone. Great job!! Oscar and Dasia for your assistance with the job!!
I generally don't like flat-fee pricing, and Bonsby's flat free pricing is outrageous. Over $600 to install a thermostat, where the thermostat itself retails for under $100? Sheesh. And the price list is top secret, the office will tell you they don't have access to it. So you only can make the decision after the tech comes out, so even if you know what needs to be done, you can't make an informed decision ahead of time.
Make sure you read your contract before dealing with this firm. I had them do a very large HVAC contact and they never returned to install the registers. I think the system is working fine, but it would have been nice to know that my painters were responsible for register installation.
had an emergency service and they told me they couldn't help for days and I should get a wet vac.
We had Michael Bonsby install a new heat pump system in November 2019. In January 2020, I discovered that the fused disconnect for the air handler had been sized incorrectly, causing two 60-amp fuses to melt, creating a hazardous condition in my home and leaving me without heat on a 17 degree day.
When I called the company to have the problem remediated, they showed up unprepared and were unable to fix the problem. Despite the presence of a warranty, I had to fix the problem myself so that my pipes didn't freeze. The company did install a new disconnect correctly some days later but dragged their feet on reimbursement, leading the field service manager to reimburse me for my fix out of his own pocket.
Recently my air handler's condensate drain pan cracked. It took a threat of legal action to get the company to fulfill their warranty service obligations. The crew that showed up to replace the drain pan did not appear to know what they were doing, and it looked like they were going to break the evaporator coil. They put the unit back together omitting the gasket that forms an air seal at the condensate drain port, then needed to take the thing apart again once I pointed out the missing gasket.
At the moment the condensate drain trap is leaking on my floor and the service covers are not installed correctly.
Larry V.A/C system went out and needed a total replacement. They were professional timely with each visit and even provided window loaners for AC while we waited for equipment to arrive. The work was done with no shortcuts and we were totally pleased with the outcome. No
Overselling was happening here. Old fashion great service and every person we dealt with did what they said they were going to do which is rare these days. Hats off to the team.
Outstanding work! Exhaust ductwork and full HVAC air duct cleaning. I recommend the Bonsby team!
Expert team installed residential dryer exhaust duct (complex drop ceiling in condo unit).

John B.My furnace was not firing up properly (Thermostat would call for heat, blower would come on, furnace would ignite for about 4 seconds then cutoff, repeat once, then blower would just run constantly until you powered down the furnace -- nice electric bill for that!)
I was under maintenance with another company, who came out for the ""No Heat"" call, and their tech (that will be ANOTHER write-up) completely mis-diagnosed the issue and created other issues - didn't know all this at this point - came and recycled power and it started - said if it kept occurring I should consider replacing the HVAC unit (12 years old) because it meant the circuit board was going on the fritz.
So - problem progressively gets worse - to the point I spend hours trying to get the gas furnace to fire up....figure - well I guess it's time for a new one.
So I call Michael Bonsby HVAC - things start REAL GOOD - get an appointment with ""David"" for Feb 10th (2021), comes out, arrives on time.
I explain what's happening and he says it's the flame sensor detector that's dirty - opens the unit, cleans it and the furnace fires right up, he identifies some potential issues that indicate the unit has other things that need to be cleaned / etc and that most places would prob. charge $750 - $1000 as its outside of standard maintenance. Closes up the unit and we go to discuss my options.
We discuss several items including new furnaces, because David says the builder installed unit is WAY over powered (like 100K BTUs and my house only needs 60K).
I'm taking all this down, asking questions, etc. David quotes me two units - a recommended one that would be properly sized and get the job done, and then a more expensive one that will provide noticeably more comfort esp. in summer (SEER rating difference from 16 to 20). We also look at and discuss my unit that handles the upstairs - David makes lots of recommendations about the insulation levels, how the ducting system was not setup properly, etc, etc. I'm taking notes, asking questions.....
As we wrap up, I ask David to quote me both types of units for install, and to quote with any additional discounts if I do both main and upstairs units at the same time (which he says he would give me additional discount). David says he will email me those quotes right away.
Nearly two weeks later - haven't heard a peep out of him. Reading back over the other negative ratings....this seems to be a habit with this company....severely undermines my trust in them to back whatever work I might have had them do.
Oh.....and to boot, NOT THE PROBLEM with the furnace failing to stay lit.
Another guy (I was having several vendors come out and quote me new units) looked at the system, and within FOUR MINUTES correctly ID'd the problem ---- which was that the air intake (which has a filter right before the furnace chamber ---- was CLOGGED with leaves (which we will discuss on the other vendor that I had a maintenance contract with). This was also contributing to the dirty flame sensor. Cleared the clog and Viola!!!! furnace works perfectly - guy tells me I still have another 3 - 5 years before I need to consider a new one. $142 for the service call and to fix the problem (and he fixed other issues my ""maintenance"" vendor had created).
That vendor is RA Home Services -- Nestor, he's getting a 5-star review from me.
Very surprised and disappointed by their unresponsiveness. Attempted four times to follow up on the estimate provided by David Cartwright regarding a humidifier/dehumidifier/air purification system for our home. The conversation that we had we he visited our home was informative; and he assured me that if we had any questions we could email him as he handed me a business card on his way out the door. We emailed him a few days later. That was Dec 5, 2019.... since then I've called 3 times and politely requested a response to our email. The phone rep said she reached out to him to let him know. My last call on Jan 3,2020, I shared with her what I've written here, resent my email in case it was lost, reacched out via their Contact Us page (https://www.michaelbonsbyhvac.com/contact/), and explained to her that it was my final attempt. Still no response.
Unfortunate, because they had a potential customer, ready and willing to purchase. Brings doubt in our mind that they are not confident in the solutions that they propose. We will continue to look for a company interested in our request.
Enrique E.Don't waste your time with this company. I had someone from their company come out to look at my HVAC system to see if duct sealing would improve flow and efficiency. I took off time from work to make the appointment - but he didn't make it. Everyone has their off days - so I gave him a pass.
We set up another time to meet and he made it - but was an hour late.
Once he got here, he tested the system and told me that they could guarantee a significant improvement in performance by sealing the ducts.
He told me he'd send me a quote shortly so that we could get started the following week. That was almost 3 weeks ago. I gave him a week - heard nothing so I texted him and got no response. I then called the headquarters and the day after he finally got back to me.
He gave me a price and told me he'd send the final proposal ""in a few minutes"". That was 8 days ago...I still don't have a proposal.
Had I gone with someone else - the work could have already been done by now.
