Very professional! Called and had someone out so fast, knew exactly what the problem was. Very happy and will use them in the future!!

Recently contacted for a new AC/ Furance install with OMNI. Justin and the team were informative, responsive and flexible during the decision process. The installers (James and team) were professional and detail oriented, installing as planned on the scheduled day. Follow-up has been great. Recommend OMNI - priced well for quality products and labor. read more

We recently used Omni Heating and Cooling to replace a boiler in a rental property. They were 1. Extremely easy to do business with; 2. Very reasonably priced; 3. Extremely professional; and 4. Got the job done quickly and as promised. I would recommend this company to anyone and everyone who needs any type of hvac work. Contractors and home maintenance companies are so often unreliable, overpriced and difficult to do business with. Omni is the exact opposite of that. Our thanks and compliments to Karis Rouse and Omni Heating and Cooling! read more

Omni Heating and Cooling Karas 215-970-7060 206 Maple St., Warminster, Pa 18974   In mid-July I called Omni to make an appointment for AC. A salesman Karis shows up and sells me on the idea of how comfortable this would be and how Omni was the right choice for me. Instillation was scheduled for a week later. I was told that the installers were the best workers at Omni. Needless to say, it is now early Sept., and I'm still hot! Being a senior citizen this condition is disastrous. Let me make this clear to you and the people you represent; there will be no more payments made to you! I was hot before you installation and I'm still hot now! If this don't get your immediate attention, I will take the money I owe you and hire a qualified company mechanic. If you want this to be a legal battle, tell me, I can handle it! (Can you?) Your company can be put on social media and ruined. You need to consider all aspects, and ask yourself if it's worth it!

OMNI is a great company, very helpful and knowledgeable. I would highly recommend them!

Nice to get professional service at a fair price! Starting with the presentation, Karis sincerely tried to customize the heat pump system to meet my needs. After weighing all options and getting his opinions, I decided on a Goodman unit. I am convinced that Goodman is as reliable as other brands based on input from a few sources. If there is any anecdotal evidence that Goodman is not as reliable, it is because some manufacturers require higher standards and training of their installers (Omni also sells Carrier, so no worries there) and the fact that some folks buying a more budget-based system may sacrifice quality with install by choosing least expensive contractor. Case in point, I had a Lennox unit that had to be replaced twice in about 9 years due to a bad install by Stanley Cooper - stay away from them as they did not stand behind their work when the unit failed after just 2 years due to "green slime" which Lennox blamed on install. Cost me $2,000 in labor to replace a 2 year old unit under warranty! Now whole system needed to be replaced with same problem. I had install today by Omni Heating and Cooling of Goodman unit which was less money and more efficient (Karis had better warranty, too) than competitors. Karis allowed me to look at all options of inside air handler and showed me important energy efficiency ratings of each combo. Kevin and crew installed and they were awesome; professional, careful, and personable. Bottom line, get a couple of quotes from whoever you want and have Karis come in last, Put aside a couple of hours for him to explain all options. I doubt you will choose anyone else after speaking with him. Very rare I give reviews like this, usually burnt by contractors, but Karis and his guys deserve it and I know how hard it is to find good HVAC contractors - hope this helps! read more

Great service, prompt, reliable and best prices in the area. Installed 2 heating furnaces in our places in fishtown. Would use again in a heartbeat and recommend to our friends. read more

I am a very tough customer for home improvement and utilities-type work, and I give OMNI an emphatic 5 star review. They were priced right from the start (4th company I looked at), and not pushy with me at all. New AC- Lennox 17 seer 2 stage. Works great, they directed me to the correct unit without a doubt. read more

I have been searching for company to rely on for HVAC service since buying my home 5 years ago. When a leak began near my evaporator coils, I decided to give OMNI a try. Our technician, Kevin, called ahead when delayed at a previous job. Once he arrived, he immediately got to work, testing multiple theories to determine the source of the leak. In the end, because of circulation loss due to dirty coils, the water from the drain pan was being pushed out and simulating a leak. Kevin was patient in diagnosing the problem and humored my questions. He proceeded to clean my coils and check the system, all for a very reasonable price, Kevin was polite and kept his work area clean. I was extremely pleased with the whole experience and recommend OMNI to anyone looking for HVAC services in the Greater Philadelphia Area. read more

I owe the safety of my family to Omni Heating. Mr. Kevin came out and discovered my heating system was leaking carbon dioxide. His assessment was so accurate and precise that a second Hvac specialist, who came out and also looked at my hvac system from the City, said and i quote, "this company's assessment was outstanding!" Two thumbs up!!!!!! -Ms. Meka read more

Have to downgrade my rating. I am disappointed in how unreliable their service department is. They never arrive within the 2-hour window of time they are supposed to. Currently the service guy is two hours late, which means I've been waiting for four hours, and no sign of him in sight. Mind you, this is a service call on a unit that was newly installed in June. The AC ran fine all summer long, but when I tried to turn on the heat the unit didn't work. I'm quickly becoming disenchanted with these folks. read more

We recently needed to replace our two oil furnaces. We received several quotes and Omni had the best price by far. Karis their sales rep was very nice and he seemed knowledgeable so we decided to give them a chance. We had two separate installations - both were not completed in the same day. The second install was on a Friday, they left before completing the job and we were without heat for the entire weekend. Unit 1 continues to work intermittently. It needs to be reset on a daily basis. Omni has been to our house several times without correcting the problem. They show up late and sometimes don't show up at all. They want to bring in an analyzer to test the system, but require a $3000 deposit for the unit - REALLY? The other unit is working, but not without some issues. After finally getting it running, we noticed an oil order in our upstairs. Omni sent a technician who could not determine the cause. The smell persisted so we called our previous heating company. They sent out a tech who found an oil leak (dripping on the basement floor). He repaired the leak and cleaned up the area - the smell is gone, but we paid for the service call. I have tried calling Karis a couple of times, but he hasn't returned any of my calls. I rarely write reviews, so for me to take the time and write this should tell you something. My advice is to do business with a different company. Yes you may get a good deal upfront, but you will be sorry in the long run. read more
